Controlled Documents Used for operation and/or maintenance of the aircraft in accordance with FAA regulations Have limited distribution within airline and require regular revisions and must include list of revisions, active and rescinded page numbers in document Noncontrolled Documents Furnished by airline and manufacturer Manufacturer’s Documentation Manufacturer’s Documentation: Airplane Maintenance Manual Component Maintenance Manuals Vendor Manuals Fault Isolation Manual Fault Reporting Manual Illustrated Parts Catalog Storage and Recovery Document Structural Repair Manual Maintenance Planning Data Document Schematic Diagram Manual Wiring Diagram Manual Master Minimum Equipment List (MMEL) Dispatch Deviation Guide Configuration Deviation List Task Cards Service Bulletins Service Letters Maintenance Tips Airplane Maintenance Manual (AMM) Contains the basic information on the operation and maintenance of the aircraft and its on-board equipment Explanation of how each system and subsystems work Basic Maintenance and Servicing action such as R&R of LRUs Functional Tests, Operational Tests, Adjustments, Replenishing of fluids and other servicing tasks Component and Vendor Manuals Component and vendor manuals are for components that are to be removed for maintenance in the shop The manuals provide same type of information on components that the AMM provides for aircraft and its systems Fault Isolation Manuals Contains a set of isolation trees for the purpose of pinpointing and fixing numerous problems related to the various systems and components on the aircraft. Fault Reporting Manual Used by Flight Crew to provide maintenance with advanced warning of malfunctions and an indication of where to begin looking for a solution prior to aircraft’s arrival. Identifies their problem using a series of questions and diagrams of system operation and instrument indication Leads to 8 digit code used by maintenance to determine solution Illustrated Parts Catalog Produced by the airframe manufacturer and includes lists and location diagram of all parts used on the aircraft model Provides information on location, part numbers, vendors, interchangeability of parts Storage and Recovery Document Info on maintenance and servicing of aircraft that are to be out of service and stored for a long period of time Procedures for draining fluids, moving aircraft so the tires will not go flat, and protecting components from the weather Structural Repair Manual Contains information for certain repairs of the aircraft structure These simple repairs are approved by FAA to be completed by the operator Other repairs must be done by the airframe manufacturer or some other FAA designated repair facility Maintenance Planning Data Document Provides the airline operator with a list of maintenance and servicing tasks to be performed on the aircraft Tasks are divided into groupings Daily, Transit, Letter Checks, Hourly Limits, Cycle Limits Tasks are divided into Letter Checks Hours, cycles, and calendar time Schematic Diagram Manual Contains diagrams of the electrical, electronic, and hydraulic systems Can be block diagram and often contain detailed diagrams Wiring harnesses, connectors, and interfacing equipment Wiring Diagram Manual Shows the complete run of wiring, including cable bundle numbers and routing, plug and connector numbers and locations, bulkheads, and other structural elements through which the wiring is routed. Master Minimum Equipment List (MMEL) Identifies the equipment which may be degraded or inoperative Systems that the flight crew may agree to accept in a degraded or inoperative condition – as long as it is fixed in a prescribed time limit set by the MMEL Contains information on all equipment available on the aircraft model to which it applies Dispatch Deviation Guide MMEL items that require maintenance prior to deferral and dispatch May need to pull and placard certain circuit breakers, disconnect power, tie up loose cables for removed equipment, and various other actions to secure aircraft and the systems against inadvertent operation Configuration Deviation List (CDL) Involves configuration of the aircraft rather than systems and equipment Provides information on panels, fairings, and similar variations in configuration that be nonstandard at dispatch as long as it does not affect the safety of flight Task Cards Certain tasks for removal/installation, testing, servicing, and similar maintenance items are produced on separate cards or sheets so that a mechanic can perform the action without taking the whole manual Service Bulletins, Service Letters, and Maintenance Tips SB is a modification of a system that will provide improved safety or operation of a system and includes detailed description of the work and parts required. SL provides information to improve maintenance actions without equipment modification Maintenance tip is suggestion to assist in their work or improve conditions Regulatory Documentation Federal Aviation Regulations (FARs) Advisory Circulars Airworthiness Directives Notice of Proposed Rule Making (NPRM) Federal Aviation Regulations (FARs) • Federal laws are collected in a document called the code of federal regulations (CFRs) • Laws for commercial aviation are under title 14 of this code – aeronautics and space – parts 1 through 200 • Certification and operation of large, commercial aircraft are part 121 • Noted as 14 CFR 121 Advisory Circulars (ACs) • A document to provide the “means, but not the only means” of complying with a regulation • Allows leeway in how regulations are to be met without micro managining the operator Airworthiness Directives (ADs) • Substantial regulations issued by the FAA to correct unsafe conditions that exist in a product (aircraft, aircraft engine, propeller, or appliance) • Aircraft owners / operators are required to maintain the aircraft in compliance with all ADs • AD include: • Description of the condition; the product to which the AD applies; corrective action required; date of compliance; where to get additional information; information on alternative methods of compliance if applicable Notice of Proposed Rule Making (NPRM) • FAA issues in advance of FAR in advance in order for the industry to have ample time to study and comment on the proposed rule change. Airline Generated Documentation • Operation Specifications • Technical Policies and Procedures Manual • Inspection Manual • Reliability Program Manual • Minimum Equipment List • Task Cards • Engineering Orders Operations Specifications (Ops Specs) • Required for each aircraft type flown • Details the airline’s maintenance, inspection, and operations programs Technical Policies and Procedures Manual (TPPM) • Usually written by engineering • Defines how all Maintenance and Engineering functions should be carried out Inspection Manual • Contents relate to all inspection activities within M&E • • • • • Mechanic inspections QC Inspection tasks Special Inspections (hard landings, bird strikes, etc) Airline’s required inspection item (RII) program The paperwork, forms, and reports required to carry out these functions Quality Assurance Manual (QA) • Defines the duties and responsibilities of the QA department and defines the processes and procedures used in the annual quality assurance audits • Forms used and reports are also covered along with the procedures for the follow-up and enforcement of QA write-ups Reliability Program Manual • Defines the relaibility program in detail so that the FAA can evaluate and approve all its elements at one time. Minimum Equipment List (MEL) • Is a customizable MMEL for the owner/operators particular airframe/engine configuration • Must carry copies in each aircraft for flight crew reference Task Cards • Produced by the manufacturer for usually one action • Simplifies tasks • Engineering section responsible for creating cards to ensure technical accuracy Engineering Orders (EO) • Maintenance work not covered in the standard maintenance plan developed by engineering • The EO must be issued as a work order ATA Document Standards • ATA Standard Chapter Numbers (pg 66) • ATA Airplane Maintenance Manual Page Block Assignments (pg 68 – 70) Closer Look at TPPM • Purpose of the TPPM is to identify all aspects of the maintenance and engineering organization • Identification of key personnel, descriptions of their job functions and their qualifications • Definition of the operator’s philosophy and goals • Layout drawings and maps of the maintenance facilities including shops, ramps, and other significant buildings and areas related to maintenance activities • Specific items IAW FAA regulations, • Controlled document – refer to pgs 71 - 73 Documentation for Maintenance Introduction (Types of Documentation) Manufacturer’s Documentation Regulatory Documentation Airline Documentation ATA Document Standards A Closer Look at the TPPM Summary Questions?
