MAINTENANCE PHILOSOPHY
The Model FA2100 Solid-State CVR Recorder is considered an “ON CONDITION LRU”
and is designed as maintenance-free unit which makes extensive use of surface mount
technology (SMT).
The repair of printed wiring assemblies (PWAs) containing SMT devices requires special-
ized factory equipment, training, and techniques, therefore, such PWAs are not field-re-
pairable while the unit is under the warranty period. As a result, during the unit’s warranty
period, the FA2100’s CVR maintenance philosophy is replacement of failed level 2 as-
semblies.
The field replaceable assemblies identified for the FA2100CVR are the Aircraft Interface
PWA, the Audio Compressor PWA, the Acquisition Processor PWA, and the Crash Surviv-
able Memory Unit (CSMU).
When it has been determined that one or more of these assemblies is faulty, the assem-
bly(ies) should be removed and returned to L-3 Aviation Recorders for repair or replacement.
Attempts to repair any discrete components of these assemblies will void the warranty.
