1.5.1 General
For practical consideration splitting of maintenance checks and performance together with lower maintenance events may be
possible as long as it is assured that each check item mentioned in the interval column of the Maintenance Program will be
repeated at the required maintenance interval. If necessary a check to be performed on parts or components located in several
positions at the aircraft (e.g. at engine 1, 2, 3 and 4) may be performed together with other, lower maintenance checks if the
time between the check does not exceed the inspection interval. Splitting of checks should be approved by Bermuda CAA.
Flight hour land flight cycle-limited items can also be treated in accordance with this paragraph.
The date/time the Certificate of Release to Service (CRS) is issued is considered to be the date/time a maintenance check has
been performed. The count for the next interval begins:
- at the date/time the CRS has been issued for tasks controlled by calendar hours;
years).
In case the maintenance check ground time exceeds the normally practiced ground time significantly, the count for
the next interval begins at the date/time a maintenance task has actually been performed.
AirBridgeCargo Airlines is responsible for managing continuous airworthiness.
Continuous Airworthiness and other Service Information will be permanently evaluated by AirBridgeCargo Airlines in
accordance with AirBridgeCargo Maintenance Control Manual Section 1.2 and where necessary appropriate action will be
taken to amend the Maintenance Schedule.

INTRODUCTION
1.9 Reliability Program
AirBridgeCargo 747-400 Reliability Program provides an appropriate means of monitoring the effectiveness of maintenance
program. Review of the reliability data may result in adjustment of the maintenance program as required.
1.9.1 Aircraft Reliability Monitoring.
Aircraft reliability data are contained in AirBridgeCargo Reliability Report issued quarterly. The report contains operational data
such as total flight hours, total flight cycles, daily utilization, etc. The data concerning incidents, maintenance reports (ma-reps)
and pilot reports (pi-reps) and flight delays and cancellations are included.
1.9.2 Engine Condition Monitoring
According to General Term Agreement between AirBridgeCargo and General Electric Company main engine parameters such as
EGT, Fuel Flow, N1, N2 , vibration, etc. are transferred via ACARS to GE Engine Remote Diagnostic Group for collecting and
analyzing with immediate notification of Duty Engineer and Power Plant Engineers of any exceedance in parameters (by e-mail
and phone call). AirBridgCargo Engine Diagnostic Group reviews Engine Data on GE site on daily basis to reveal any deviations
such as abnormal trends or shifts to perform correcting actions timely. In case of ACARS malfunction GE sends notification of
missing data to AirBridgeCargo Engineering. On request pilots provide Engineering with snapshot of engine parameters for
analysis and correcting actions and GE data base. Flight Data Monitoring Group receives Flight Data from DFDR, proceeds them
and sends data with exceedance to Power Plant Engineers for analyses and correction actions.
1.9.3 Component Reliability Monitoring
Component reliability data such as MTBR, MTBUR, MTBF will be contained in AirBridgCargo Reliability Report issued
quarterly.

INTRODUCTION
2. Maintenance Program
2.1 Line Maintenance
Line Maintenance should be understood as any maintenance that is carried out before flight to ensure that the aircraft is fit for the
intended flight. Line maintenance may include:
Component replacement with use of external test equipment if required component replacement may include components such as
engines and APU.
conditions/discrepancies but do not require extensive in-depth inspection. It may also include internal structure, systems and
powerplant items which are visible through quick opening access panels/doors.
sive disassembly and can be accomplished by simple means.
For the purpose of protection from inclement weather conditions (including ambient air temperature below 5 degrees Celcius)
during performing line maintenance tasks the hangar (or component workshop structures) should be provided to a standard that
prevents the ingress of rain, hail, ice, snow, wind and dust etc. into the maintenance area and ensures proper environment to
perform the tasks.
Line Maintenance Checks:
PF/TRANSIT Preflight/Transit Check
Tasks are to be performed prior to each flight.
The PF/Transit Check has to be performed at ramp position not earlier than two hours before take-off.
Preflight Check is split to two phases: After Arrival Check and Preflight Before Departure Check and is performed according to
Task Cards B744-00-000-00-01A - PREFLIGHT / TRANSIT CHECK AFTER ARRIVAL and B744-00-000-00-01B
PREFLIGHT CHECK BEFORE DEPARTURE.
Task Cards provide instructions to perform actions according to Check Lists B744-00-000-00-01A-CL and B744-00-000-00-01BCL, located onboard the aircraft.

INTRODUCTION
NOTE: Training and test-flights. Before the first take-off of a training flight or a test flight a PF/Transit Check has to be
performed. After each training flight or a test flight a walk around inspection has to be performed. The PF/Transit Check has to
be repeated if the training or test flight is interrupted for more than 2 hours.
During an en-route stop in case of maintenance personnel is not available the Transit check could be performed by the task trained
flight crew. It basically is a walk-around inspection which requires a check of the aircraft interior and exterior for obvious damage,
leaks, proper operating equipment and security of attachments.
Flight crew perform preflight inspection according to FCOM and final release the aircraft to flight after completion of the
maintenance preflight check.
DAILY - Daily Check
Daily Check is to be accomplished before the first flight of each calendar day or once every 24 hours elapsed time, not to exceed
48 hours elapsed time. CMR items with DAILY intervals (if any) are to be performed not to exceed 24 elapsed hours.
A - A-Check
The "A" Check is to be accomplished at intervals not to exceed 1000 Flight Hours.
Tasks selected for "A" Check (or multiples thereof) are so specified in the "Frequency" column of the task summary.
A-Multiples based on the A-interval are 1A, 2A, 3A, 4A.
2.2. Base Maintenance
C - C-Check
The C-Check is to be accomplished at intervals not to exceed 10000 flight hours or 24 months calendar time whichever comes first.
C-multiples based on the C-interval are 1C, 2C, 3C, 4C.
NOTE: No multiple "C" Check task is to be escalated until at least ONE airplane inspection has been satisfactorily accomplished
at 20,000 flight hours for 2C tasks, 30000 flight hours for 3C tasks and 40,000 flight hours for 4C tasks.
D - D-Check
The D-Check inspection interval is 8 years for initial and second D-Check, thereafter the D-Check inspection interval is 6 years.
Example: 8 years, 8 years, 6 years thereafter.

INTRODUCTION
For multiple A-, C- and D-Checks use multiples of the basic check intervals stated above, (e.g. 2A=2000FH, 3C=30000 FH and
2D=16 years. Repeat 2D=12 years thereafter.
An operator may desire to perform the "A", "C", and/or "D" check on a continuous or a progressive maintenance program system;
i.e., the "A", "C", and/or "D" check would be phased into a number of individual check packages. This would be considered
acceptable provided the maximum interval between successive check packages does not exceed the letter check interval.
Time Controlled Maintenance
In addition to the intervals expressed in letter codes other parameters are used such as:
Flight hours
FH
Flight cycles
FC
Calendar time
- days
DY
- months
MO
- years
YR
Engine/APU Change
ENG/APU CNG

INTRODUCTION
LUB - Lubrication
The term "SERVICE" or "LUBRICATION" implies that a component or system should be checked and serviced with
fuel, oil, grease, water, oxygen, etc., to a level or condition specified by the appropriate Maintenance Manual
procedure. "SERVICE" may also be used to indicate that filter cleaning or replacement is recommended.
DET - Detailed Inspection
An intensive examination of a specific item, installation, or assembly to detect damage, failure, or irregularity.
Available lighting is normally supplemented with a direct source of good lighting at an intensity deemed appropriate.
Inspection aids such as mirrors, magnifying lenses, etc. may be necessary. Surface cleaning and elaborate access procedures
may be required.
GVI - General Visual Inspection
A visual examination of an interior or exterior area, installation or assembly to detect obvious damage, failure or
irregularity. This level of inspection is made from within touching distance unless otherwise specified. A mirror may be
necessary to ensure visual access to all surfaces in the inspection area. This level of inspection is made under normally
available lighting conditions such as daylight, hangar lighting, flashlight or drop-light and may require removal or
opening of access panels or doors. Stands, ladders or platforms may be required to gain proximity to the area being
checked.
OPC - Operational Check
An "Operational Check" is a test used to determine that a system or component or any function thereof is operating
normally.
FNC - Functional Check
A "FUNCTIONAL CHECK" is a detailed examination in which a complete system, sub-system or component is
checked to determine if operating parameters are within limits of movement, rate of flow, temperature, pressure,
revolutions per minute, degrees of travel, etc., as prescribed in the manufacturer/vendors Maintenance Manual.
VCK - Visual Check
A "Visual Check" is an observation to determine that an item is fulfilling its intended purpose. Does not require
quantitative tolerances. This is a failure finding task.
SDI Special Detailed Inspection
An intensive examination of a specific items, installation or assembly to detect damage, failure or irregularity. The
examination is likely to make extensive use of specialized inspection techniques and/or equipment. Intricate cleaning
and substantial access or disassembly procedures may be required.

Maintenance Manual.
3. The tasks listed are to be accomplished at the specified intervals. The most appropriate task interval (frequency and usage
parameter) has been used in determining the APU scheduled maintenance task requirements. Conversion factors (i.e., APU hour to
flight hours) could be determined with the approval of regulating authorities for incorporation into the maintenance program,
provided such conversion does not exceed the interval shown for the tasks.
POWERPLANT
1. With the exception of life-limited parts, off-wing (in-shop) maintenance tasks are not included herein. Off-wing tasks shall be
controlled by AirBridgeCargo Airlines based on contractual arrangements with General Electric Company.
2. Limitations of life-limited parts are controlled by the engine manufacturers and are published in the General Electric CF6-80C2,
Engine Manuals, Section 5.
2.4. Structural Maintenance Program
The program is designed to provide timely detection and repair of structural damage which may occur in the fleet during
commercial operations. Detection of corrosion, stress corrosion, minor accidental damage and fatigue cracking by visual and NonDestructive Test (NDT) procedures is considered. Major accidental damage such as that caused by bird strike or large ground
handling equipment is considered readily detectable. Additionally fuel leaks, loose fasteners, loss of cabin pressure, etc. are
considered readily detectable and continue to be an essential part of Structural Maintenance Program.

NOTES:
1. Tasks for detecting corrosion, stress corrosion and minor accidental damage using visual and/or Non-Destructive Test (NDT)
procedures are specified. After discrepancies are found, repair or modification action may be required to assure continuing
airworthiness of the airplane.
2. Inspection
An examination of an item against a specific standard to detect irregularities and discrepancies such as wear, deterioration,
damage, corrosion, cracking, etc. Certain inspection tasks are used in Structural Maintenance Program General Visual
Inspection (GVI), Detailed Inspection (DET) and Special Detailed Inspection (SDI). A list of inspection tasks is given in para
2.9 Task codes and definitions.
2.4.1 Structure Program Operating Rules
1. All airplanes in AirBridgeCargo 747-400 fleet are subject to the provisions of this section. These include requirements for
external and internal structural inspections, corrosion prevention and control tasks.
2. Intervals for the structural maintenance program are expressed in calendar time and/or letter check. Any interval change would
be substantiated by service experience and handled by Regulatory Authority approved program revision procedures as applicable.
3. The 747-400 Corrosion Prevention and Control Program (CPCP) is an integral part of the Structures Inspection Requirements.
All tasks in the Structure Maintenance Program require the application of the CPCP basic task at the specified intervals. The
objective of the CPCP is to control corrosion found on all structure listed in the Structures Maintenance Program to Level 1 or
better.
4. Deviation from the structural program defined in this document should be coordinated and approved by the Principal
Airworthiness Inspector (local regulatory authority).
5. Special Detailed inspections are to be used when specified for inspecting hidden details or may be used as alternatives to
detailed visual inspections.
Hidden details requiring NDT procedures are listed under appropriate zones either internally or externally. Procedures for
conducting these Special Detailed inspections are given in the Boeing Non-Destructive Test Manual (D6-7170).
6. Normal cleanup procedures are to be used prior to conducting general visual or detailed inspections. Specified cleanup
procedures are to be used for special detailed inspections. Sealant and corrosion protection finishes should only be removed when
specified and restored in accordance with the Corrosion Prevention Manual (D6-82560) after the task is completed.
7. Excessive dust, debris, or overspray of corrosion inhibiting compounds, found during any inspection, are considered to be
unsatisfactory condition possibly reducing the fire resistance of the airplane design. Cleanup of these materials should be a
standard part of maintenance activity. (Reference Service Letter 747- SL-25-170)..

INTRODUCTION
2.4.2 Fatigue related inspection program
For a listing of fatigue related inspection requirements please refer to the 747 Supplemental Structural Inspection Document (D635022) and 2.6 of the Maintenance Program.
The FAA published final rule addressing widespread fatigue damage (WFD). The rule requires to establish a Limit of Validity
(LOV) for the engineering data that supports the structural maintenance program of most transport category airplanes.
The LOV values for 747-400 (Group 1 aircraft) are 35000 flight cycles or 165000 flight hours whichever occurs first.
2.4.3 Corrosion Prevention and Control Program (CPCP)
Structural maintenance requirements are determined on the basis of continual maintenance to preserve or restore the inherent
corrosion preventive measures and structural surface finishes.
As the CPCP maintenance requirements have been integrated into the Structures and Zonal Requirements, the CPCP Basic Task
steps apply to both sections and are listed as follows:
1. Remove all obscuring systems, equipment, material and furnishings to allow access to the area to be inspected. It is not
necessary to remove bushings unless specified in the task description, or there is an indication of corrosion, or that the bushing has
migrated.
2. When cleaning the inspection area as necessary to accomplish the inspection, it is not necessary to remove normal amount of
sealant/leveling compound or protective films or finishes unless these items have deteriorated to the point where moisture can
penetrate. A light uniform film of corrosion inhibiting compound (CIC) that has not accumulated dirt or debris will normally allow
adequate inspection of the structure without removal. Obscuring CIC may require removal if there are multiple layers, evidence of
moisture, and/or accumulations of dirt or debris.
3. Visually inspect all structures items and other structure described and accessed in the Structures and Zonal Maintenance
Requirements for evidence of corrosion or hidden corrosion. The inspection method is as specified in each task description. Use
additional non-destructive inspections or visual inspections, as appropriate if there are indications of hidden corrosion, such as
bulging skins, or corrosion running into splices or under fittings, etc. Note possible effects from adjacent items not specified that
may have caused corrosion problems.
4. If found during any maintenance opportunities, in addition to and including activities specified in this requirement, remove all
corrosion (see SRM 51-21-01, or the Corrosion Prevention Manual D6-82560), evaluate damage, and repair or replace all
discrepant structure as necessary, including restoration of protective finishes, sealants and other materials. Program evaluation of
corrosion and revision of the program schedule and procedures, and reporting of corrosion Level 2 or 3 is required.
5. Clear any blocked holes or gaps, and sources of blockage that may hinder drainage, as applicable.

INTRODUCTION
6. Restore inspection area finishes, sealants, corrosion inhibiting compounds, lubricants and other protective materials per the
current prescribed procedures in the SRM 51-10-02, or the Corrosion Prevention Manual D6-82560. Apply suitable approved
water-displacing/anti-corrosion compounds, finishes, sealants, or lubrication as appropriate and only if the previous applied
covering has been disturbed, or removed except as noted in the table below. As an option, applying a single coat of water
displacing/anticorrosion compound is acceptable, that penetrates faying surfaces, displaces moisture and forms a durable barrier
after drying, e.g. a single coat of BMS 3-35, where the initial or previous coat has been disturbed or removed. It is recommended,
in areas with high potential for severe corrosion, to apply a single coat of BMS 3-23 or equivalent followed by a single coat of
BMS 3-26 Type II or equivalent.
NOTE: Corrosion inhibitors contain flammable components. Do not expose these materials to open flame, active circuits or other
components where a potential fire hazard may exist. Maintain safety precautions until all volatile materials have evaporated to
include installation of insulation blankets.
7. Ventilate and dry any wet insulation blankets prior to re-installing, or replace with new, as necessary. Reinstall insulation
blankets with drainage holes down, facing interior of airplane.
NOTE: Do not apply water displacing/anti-corrosion compounds in the following areas:
Cables, pulleys, wiring, plastics, oxygen systems.
Adjacent to tears or holes in insulation blankets.
Interior materials, including cargo liners.
APU, APU shroud or any structure in direct contact with the APU.
Over Cosmoline 1058 or equivalent per MIL-C-16173 Grade 1.
Lubricated or Teflon surfaces (e.g. greased joints, sealed bearings).
Areas with electrical arc potential.
Engine strut cavities or cowling structure.
Regions where temperature exceeds 220 degrees Fahrenheit (100 degrees Centigrade).
2.4.4 Transportation of live animals
In case of transportation of live animals in cargo compartment appropriate maintenance will be performed in accordance with
AMM 51-00-60 to prevent corrosion build up.

INTRODUCTION
2.5. Zonal Program
The Zonal Inspection Program includes a General Visual and, if required, physical check of the general condition and security of
attachment of the accessible systems and structures items contained in defined zones. This includes checks for degradation such as
chafing of tubing, loose duct supports, wiring damage, cable and pulley wear, fluid leaks, electrical bonding, general condition of
fasteners, cracked, chipped, or missing paint on composite structure, inadequate drainage, etc., and general corrosion. The Zonal
program packages a number of General Visual (GV) Inspections and Visual Checks (VCK) into one or more zonal inspections.
The program includes any GVI/VCK tasks required to assure security of attachment and general condition of any system or
structural items within the zone.
The Zonal Inspection Program serves two primary purposes:
a. To assess the general condition and security of attachment of all systems and structures items contained in each zone by use of
adequate zonal inspection tasks.
b. To package a number of GVI/VCK tasks generated against Maintenance Significant Items (MSIs) and Structures Significant
Items (SSIs) into one or more Zonal tasks.
2.5.1 Zone program rules
1. The Zonal Inspection Program contains a series of tasks identified as Inspection-Zonal . This inspection is defined as:
"A visual examination of an interior or exterior area, installation or assembly to detect obvious damage, failure or irregularity. This
level of inspection is made from within touching distance unless otherwise specified. A mirror may be necessary to ensure visual
access to all surfaces in the inspection area. This level of inspection is made under normally available lighting conditions such as
daylight, hangar lighting, flashlight or drop-light and may require removal or opening of access panels or doors. Stands, ladders or
platforms may be required to gain proximity to the area being checked".
Adequate lighting and normal inspection aids are to be used as required, such as flashlight and/or inspection mirror.
2. Internal/External, as used in the Zonal inspection tasks, refers to the point from which the inspection is accomplished in relation
to the zone.
3. The zonal task includes visual checks of all electrical wiring, hydraulic tubing, water/waste plumbing, pneumatic ducting,
components, and fittings, brackets, etc., associated with systems as well as all visible structure which are contained within the zone
boundaries. The extent of the intended area of the inspection is defined by the access, if any, listed with each inspection item.
4. General Visual Inspections included in the zonal program are to detect obvious unsatisfactory conditions, damage, failures,
irregularities / discrepancies in visible structure, systems and powerplant installations or assemblies. Inspection/checks other than

MAINTENANCE PROGRAM
Boeing 747-400F
INTRODUCTION
"General Visual" are not included in the zonal program and are listed as separate tasks in the respective Systems, Powerplant or
Structures Programs sections.
5. Detailed (DET) and Special Detailed Inspections (SDI) are not contained in the Zonal Inspection Program.
6. Zones which contain systems/components/installations are assigned a zonal inspection task to be performed at specified
intervals.
7. The scope and intent of what is to be inspected is based on what is visible within the zone with the specified access open. Any
fairings, panels, or other items which are specified to be opened to gain access to a particular zone should also be inspected if they
are not covered by a separately defined zonal task.
2.6 Certification Maintenance Requirements (CMR)
CMRs are listed in Boeing document D621U400-9 which forms MPD Section 9. A CMR is a required periodic task, established
during the design certification of the airplane as an operating limitation of the type certificate. CMRs usually result from a formal,
numerical analysis conducted to show compliance with catastrophic and hazardous failure conditions.
A CMR is intended to detect safety-significant latent (hidden) failures that would, in combination with one or more specific
failures or events, result in a hazardous or catastrophic failure condition. CMRs are derived from a fundamentally different
analysis process than the maintenance tasks and intervals that result from the Maintenance Steering Group (MSG-3) Analysis
associated with Maintenance Review Board (MRB) activities. MSG-3 Analysis activity produces maintenance tasks that are
performed for safety, operational, or economic reasons, involving both preventative maintenance tasks, which are performed
before failure occurs (and are intended to prevent failures), as well as failure-finding tasks. CMRs, on the other hand, are failurefinding tasks only, and exist solely to limit the exposure to otherwise hidden failures.
CMRs are designed to verify that a certain failure has or has not occurred, and do not provide any preventative maintenance
pair if it
has failed. Because the exposure time to a latent failure is a key element in the calculations used in a safety analysis performed to
show compliance with FAR 25.1309, limiting the exposure time will have a significant effect on the resultant overall failure
probability of the system. The CMR task interval should be designated in terms of flight hours, cycles, or calendar time, as
appropriate.
All applicable CMRs are included into System & Powerplant Maintenance Program Section with the CMR Number next to the

INTRODUCTION
2.7 Fuel Systems Airworthiness Limitations (AWL)
Airworthiness Limitations are listed in Boeing document D621U400-9 which forms MPD Section 9. AWLs are to meet standards
and assumptions, introduced by FAR 25.981 and Special Federal Aviation Regulation SFAR 88.
An AWL may be an Airworthiness Limitation Instruction (ALI) and Critical Design Configuration Control Limitations (CDCCL).
All applicable AWLs are included in Airworthiness Limitations Section of the Maintenance Program.
CDCCL are means of identifying certain design configuration features intended to preclude a fuel tank ignition source for the
operational life of the aircraft. A critical fuel tank ignition source prevention feature may exist in the fuel system and its related
installation or in systems that, if the failure condition were to develop, could interact with the fuel system in such a way that an
unsafe condition would develop without this limitation.
ALIs identify inspection tasks related to fuel tank ignition source prevention which must be done to maintain the design level of
safety for the operational life of the aircraft.
CDCCLs and ALIs are mandatory and cannot be changed or deleted without the approval of the FAA Seattle ACO that is
responsible for the aircraft model Type Certificate or applicable regulatory agency. Strict adherence to configuration, methods,
techniques or practices as prescribed is required to ensure compliance with the CDCCLs and ALI. Any use of methods, techniques
or practices not contained in the applicable ALI and CDCCLs must be approved by the FAA Seattle ACO that is responsible for
the aircraft Type Certificate or applicable regulatory agency.
2.8 Supplemental Structural Inspection Program (SSID)
The requirements of Boeing Document D6-35022 Supplemental Structural Inspection Program to ensure continuing structural
airworthiness are applicable for aircraft approaching 20000 flight cycles for all structure or 100000 flight hours (for wings) in the
Maintenance Schedule. The program is to be incorporated into a separate Section of Maintenance Schedule on approaching the
threshold.
2.9 Identification of MSIs and SSIs
Maintenance Significant Items (MSI) and Structure Significant Items (SSI)
MSIs
are items identified by manufacturer whose failure could affect safety (on ground or in flight) and/or are undetectable during
operations and/or could have significant operational impact and/or could have significant economic impact. There are MSG-3
Failure Effect Categories for each MSI in 747-400 MRB-Document.

2.10 Component Maintenance Program
The Component Maintenance Program of the Maintenance Program includes
components related tasks as required per the MPD, MRB, AWL and CMR and the tasks to be periodically performed on aircraft
components after an operative or storage period. It defines the periods / limits at which off-aircraft maintenance and / or
replacement of life limited parts by new or appropriately shop maintained parts should be made and intervals of periodic on/offaircraft components maintenance.
A
component is a component that requires a specific action at a specific interval (replacement, overhaul,
refurbishment, bench check, etc.) per the manufacturers recommendations.
A
component is a component that requires a specific action (replacement, overhaul, refurbishment, bench check, etc.)
chosen by the operator to be done at a specific interval based on Reliability Program analysis but may be adjusted to fit operational
schedule in accordance with para 2.11.3 Permitted Variations of Task Frequencies of the subject Maintenance Program
Introduction.
Life limited Component means any Part that is required either by the Airframe, Engine, Appliance, or Part manufacturer or by
the Aviation Authority or by the Maintenance Program to be overhauled or replaced after a certain number of hours, calendar time,
cycles, or landings, including without limitation life-limited parts, rotables, and discard items.

2.11.4 Implementation period of new tasks
Implementation period is a threshold for accomplishment of new tasks derived from Boeing 747-400 MPD revision, other
regulatory requirements or service experience for the aircraft already in service.
The policy below is applied to the new task implementation unless it is specified otherwise by regulations.
For the items controlled by Flight Hours/Flight Cycles the threshold is counted from the Maintenance Schedule Revision approval
date unless the item could be accomplished at the nearest corresponding Letter Check.
For the items, controlled by Letter Checks the first accomplishment is to be at the nearest corresponding Letter Check unless the
Letter Check Work Package has been already provided to the Maintenance & Repair Organization. In this case the item is to be
implemented at the nearest lower letter check.
For the items, controlled by Calendar Time the first accomplishment is to be together with other items, having the same interval, at
the nearest possible opportunity.
2.12 Structure Repair Inspections Section
Once repair on aircraft structure has been performed it is categorized as Permanent, Interim or Time-limited for repairs that have
not been evaluated and analyzed for damage tolerance and as categories
for the damage tolerant repairs in
and interim repairs must be inspected at specified threshold and
repeat intervals. Repairs for certain aircraft are included into Structure Repair Inspections Section.
2.13 Special Rules for Parked or Stored Aircraft
An aircraft taken out of operation and parked or stored for more than 24 hours must be maintained according to the following rules:
All maintenance requirements and checks defined in the Maintenance Schedule which become due during the parking/storage
period, may be postponed until the end of the parking period (unless required by AMM).
All deferred and open items, scheduled for rectification during the parking period, may be postponed until the end of the parking
period (unless required by AMM).
All changes of components, which become due during the parking period according the Maintenance Program, may be postponed
until the end of the parking period (unless required by AMM).
All EOs, SBs, SLs, ADs and national authority requirements, which become due during the parking period, may be postponed
until the end of the parking period provided there is no specific requirement during the parking/storage period.
Provisioning relating components, APU or engine removals during the parking/storage period are allowed. The reinstallation of a
component, APU or engine can be postponed until the end of the storage/parking period but has to be performed in accordance
Issue 3 Revision 23
ABW747-400MSG3MP

Boeing 747-400F
INTRODUCTION
with all relevant procedures. All outstanding work and component replacements must be completed before return the aircraft
back into service. For appropriate handling of a removed components, APU or engine before installation in another aircraft refer
to the relevant procedures.
For maintenance requirements and maintenance checks limited in Maintenance Program with calendar time an interval credit
may be used. The amount of the interval credit depends on the duration and the condition of the parking/storage and subjects to
national authority approval.
Before the aircraft is returned to service all postponed maintenance requirements and checks defined in the Maintenance
Program, all component changes as required by the Maintenance Program, SBs, SLs and ADs, national authority requirements
and rectification of deferred items must be performed.
Calendar time intervals for scheduled maintenance tasks may be halted (sometimes referred to as Clock Stoppage) from the
Airplane Maintenance Program while in a maintenance or preserved status as long as the following are met:
1. For aircraft in storage, the airplane must be preserved and maintained in accordance with applicable Boeing Active, Short,
Medium or Long Term Storage Prolonged Parking procedures. These procedures may be found in Chapter 10 of the Airplane
Maintenance Manual (AMM). All applicable storage inspections are to be scheduled and followed.
2. The Storage Inspection Program is meant to keep the aircraft in preserved status and not require the accomplishment of normal
scheduled maintenance as described in the Airplane Maintenance Program. In other words, the scheduled maintenance tasks
within the Maintenance Review Board Report (MRBR) and the Maintenance Planning Document (MPD) are intended for use on
in-service airplanes. They are not intended for stored airplanes, so the maintenance items that would become due during the
storage period can be performed at the end of the storage as part of de-preserving the airplane and re-certifying for revenue flight.
The aircraft must conform to applicable airworthiness requirements and limitations of the maintenance program and local
regulations. While there is no accumulation of FH and FC, calendar time items may get some storage credit as negotiated
between the operator and the local regulatory agency, as long as the airplane is properly preserved as noted above and stored in
an environment not promoting corrosion. Calendar items that cannot have the clock stopped typically includes items such as
emergency equipment like rafts, slides, flotation devices, oxygen masks, batteries, fire bottle squibs and medical kits (this is not
an all-inclusive list).
3. Clock Stoppage is also not applicable to AD's, Life Limited Parts, CMR's, SCI/AWL's, or AWL's. Any overdue AD's, Life
Limited Items/Parts, CMR's, SCI/AWL's, AWL's, must be complied with before return to service.
4. The date the airplane entered maintenance / the storage program should be noted in the airplane log, to track the duration of
clock stoppage as applicable.
5. For scheduled maintenance tasks that have been halted, the clock restarts at Maintenance Release.

2.14 Specific Aircraft Operations
2.14.1 CAT II/CAT III Operation
All AirBridgeCargo 747-400 aircraft are approved for CAT IIIa operations and Low Visibility Takeoff RVR 150.
Boeing Document D6-35236 and FAA Advisory Circular 120-28D provide information on equipment, data and procedures
necessary for CATII/CAT III operations. To remain in CAT III status a periodic low visibility system use or a satisfactory systems
ground check should be accomplished.
System and
Powerplant Maintenance Program Section.
2.14.2 Reduced Vertical Separation Minimum (RVSM).
Boeing Service Letter 747-SL-02-011 provides information on the engineering data, necessary avionics equipment and procedures
concerning qualification of Model 747-400 airplanes to use Reduced Vertical Separation Minimum (RVSM) procedure. The SL
also provides the required inspection for continuous airworthiness.
System Maintenance and External Inspections
The Maintenance Review Board Report defines the required inspections for continued airworthiness. Boeing MPD 747-400
contains all MRBR requirements. Each MPD item is reflected in Boeing Task Cards. The scheduled maintenance tasks required
for continued RVSM compliance are the required scheduled maintenance tasks in the current revision of the 747-400 Maintenance
Review Board Report.
Skin Waviness
Service experience has shown that the design of airplane Section 41 in the extra critical RVSM area encompassing the Pitot Static
Probes and AOA sensors is such that distortion is kept to a minimum when subjected to airplane design loads. Skin waviness does
not change over time with normal airplane operation. Damage and/or corrosion on the skin or supporting structure in the vicinity
of the Pitot Static probes and AOA sensors needs to be addressed by non-routine repair procedures specific for maintaining RVSM
AMM 51-10-00-601 defines the fuselage skin waviness measurement procedure.
Fuselage skin waviness surrounding the Pitot Static Probes is required to be measured only when visual inspections reveal skin
damage or repairs. A scheduled periodic in-service measurement of skin waviness is not required.

INTRODUCTION
Altimetry/Avionics System
Existing Boeing recommended inspection and maintenance schedules for altimetry and height keeping/monitoring system
equipment are adequate for RVSM. There are no additional scheduled maintenance requirements for the automatic altitude control
system, the altitude alert system or the ATC transponder. However, periodic maintenance shall continue to be performed in
accordance with FAR 91.413 requirements for 24-month ATC/Mode S Transponder and inspection cycle per FAR 43, Appendix f.
NOTE: Refer to MS item 3405301-100.
There are no RVSM specific maintenance requirements for the altimetry data system. Periodic maintenance shall be performed in
Also no additional
changes to the Air Data test equipment are required. The Air Data test equipment presently defined in 747-400 AMM Section 3412ion, existing AMM inspection
and maintenance schedules, as outlined in MRB/MPD for the altimetry system, are adequate and satisfy the RVSM accuracy
requirements.
Structural Repair Manual (SRM)
The SRM does allow for some skin damage. SRM 51-10-01 defines the aerodynamic smoothness requirements in the vicinity of
the Pitot Static Probes and AOA sensors and SRM 51-10-03 specifies the RVSM allowable damage and external repairs for
RVSM-qualified aircraft. SRM 51-10-03 restricts nonand AOA sensors. For damage and/or external repairs in the region surrounding the PItot Static Probes and AOA sensors that
exceeded the SRM allowable limits, the operator is encouraged to contact Boeing with the description of the damage/repair to the
2.15 Human Factors Critical Task Control
The practice of performing maintenance on any critical system may present opportunities for error. Maintenance of all multiple
critical airplane systems at the same time or by the same individual or team presents the potential for similar errors being
introduced onto multiple systems. This risk of error can be offset through staggered maintenance, varying maintenance personnel,
developing specific processes for critical system maintenance and educating maintenance personnel about critical systems. The
means above eliminate the potential that improper maintenance will occur on similar or backup systems. Worldwide fleet
experience has shown that this policy will improve airplane reliability.
System maintenance requirements should be purposely designed to avoid working on critical redundant systems during a single
maintenance visit. Additional processes or instructions such as checklists, cross-checking work performed, using tools provided by

4. Weighing
The Boeing 747-400 Weight and Balance Manual describes the recommended procedures for preparation and weighing of the
model 747-400 airplane. Each aircraft will be weighed and the C of G location established prior to being placed into service. New
production aircraft delivered to the airline and weighed by the manufacturer are eligible to be placed into operations without
reweighing if no or only minor change and equipment installation are accomplished by the airline.
Aircraft will be weighed after major repair or after major alteration unless reliable data, allowing analytical calculation of weight
and balance change, are available. Each aircraft will be weighed every 5 years. The weighing procedure to be followed is defined
in Airplane Weight and Balance Control and Loading Manual D043U542 Chapter 1-82-001.

Over-Current and Arcing Protection Electrical Design Features
Operation Fault Current Detector (FCD) for Center Wing Tank
(CWT) Pumps, and Inboard Main Tank Override/Jettison (O/J)
Pumps and Horizontal Stabilizer Tank (HST) Transfer Fuel
Pumps
Concern: Potential for pump housing burn-through, either
internal or external to the fuel tank, as a result of major arcing
due to electrical failure (i.e., damaged electrical connector, stator
windings or lead wire to housing/end cap shorting).
The FCD is designed to detect electrical faults and open the
circuit prior to pump housing burnthrough.
The following action is required in order to ensure continued
functionality of each fuel pump FCD circuit (refer to Boeing AMM
28-17-14 for HST transfer pumps and AMM 28-31-14 for CWT
and inboard main tank pumps):
1. Using the FCD test equipment, The Boeing Company (81205),
2805401-100 Part Number: G28013-20, perform the following operational test
of the HST, CWT, Inboard O/J Pumps FCD:
a. Verify that the fault current detector test equipment, POWER
PHASE ON indicator lights for phases A, B, and C go off once
the LOAD switch on the fault current detector test equipment is
set to the LOAD position for the following pumps:
I. L HST Pump M7862
II. R HST Pump M7863
III. L CTR Fuel Override Jettison Pump M224
IV. R CTR Fuel Override Jettison Pump M225
V. Main 2 FWD Override Jettison Pump M222
