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

Ref. PBBE Flexible Sustainment Guidehttps://acc.dau.mil/GetAttachment.aspx?id=19314&pname=file&lang=en-US&aid=980 -

• 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

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

DTM Transfer

Maintainer Always Receives PositiveAction From Technical Data (e.g. NextAction).

1) CFRS - Determine existence of fault.

2) CFI - Determine most likely cause of fault. Identify corrective action to be performed.

a DTM is similar to a thumb drive

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
