Requirements
•
•
•
•
Implement F3I
Guaranteed mission capability rate
Support peace and war time scenarios
USAF/Contractor forms partnership for
sustainment over the system life cycle
• Affordable cost to USAF
Implements F3I Requirements
• Performance based specifications
– Form, Fit, Function Interface (F3I)
– ‘How to’ responsibility given to Contractor
• Contractor Depot Maintenance
– Helps mitigate the risk of short lived technologies
– Contractor has configuration control internal to LRU
• Facilitates technology insertion
• Utilizes Trigger Based Item Management (TBIM)
Process
– Provides for trends and targets actions that provide high payoff
– ‘Proactive’ rather than ‘reactive’ management

Elements of PBL
(Continued)
• Proper O level maintainer training and technical information
– Tech Pubs (plane side repair data) updated during EMD
– CFR/CFI system update; deployment during OT&E
– All technical information evaluated vs “as designed”
– Inclusive Diagnostic System at all levels of assembly
• Automated configuration management required
– For tracking:
Base
Aircraft
LRU
SRU
Critical Component
– Manage parts inventory
– Tracking of bad actor hardware, remove when necessary
PBL Implements F3I Criterion

Shared Responsibility is Key to Success
• Contractor - Provide adequate spares based upon MTBMA
• USAF and Contractor - Minimize Mean Down Time (MDT)
– USAF - 45 Minute MTTR
– Contractor - 5 Hour stores replenishment time (for spares)
– USAF - 8 Hours for local transportation, preparation of
maintenance action and requisition forms,
pack and ship
• Technical Performance Measurands will be implemented to help
manage the program, minimize MDT

CFRS/CFI
1) CFRS - Determine
existence of fault.
2) CFI - Determine most
likely cause of fault.
Identify corrective action
to be performed.
• Perform Additional
Troubleshooting Procedure
and Repair System
• Perform System Verification
PMA
Maintainer Always Receives Positive
Action From Technical Data (e.g. Next
Action).
CFR/CFI System
• Proposed Process
CFR / CFI
(Eliminates need for Fault Isolation Tech manual)
Identify Corrective
Action Required
How is this Done?
If “How To” instructions are not required
Is the Fault Corrected?

Functional Requirements
• Automated Fault Detection
– Provided by on-aircraft system BIT and supplemented with
CFRS
– Accomplished via updates to WIN-95 CFRS
• Automated Fault Isolation capability
– Provides “POSITIVE ACTION” to maintainer
– Electronic automated tool implementation includes Digital
Wire Diagrams
• Currently done with paper manuals today
• Automated data collection
– Enables collection and manipulation of data collected
– Includes maintenance corrective action and parametric
information
Advantages
• CFI data base can readily be updated in 1-2
weeks time frame
– Not Tech Pubs update dependent (months/years
time frame for paper update)
– Maintainer now gets real time data to help isolate
failures
• Portable Maintenance Aid (PMA) compatible
• Deletes paper Fault Isolation/Wiring Diagram
(FI/WD) manuals
