L3 FA2100 CVR Component Maintenance Manual With Illustrated Parts List page 256

1. GENERAL
This section is intended to contain information required to restore a worn or damaged part
to a serviceable condition. However, the Fairchild Model FA2100 Cockpit Voice Recorder
is a completely solid-state device that does not contain any electro-mechanical moving
parts. The Model FA2100CVR has been designed as maintenance-free unit which
makes extensive use of surface mount technology (SMT). The repair of printed wiring
assemblies (PWAs) containing SMT components requires specialized factory equipment,
training, and techniques, therefore, such PWAs are not field-repairable. Only the L−3AR
Repair Station, FAA: LD7R612J; EASA.145.4620 is authorized to repair the FA2100CVR
to component level in accordance with L−3AR Factory test, calibration and repair speci-
fications.
As a result, the Model FA2100CVR's maintenance philosophy is replacement of failed as-
semblies. In the case of the Model FA2100CVR, the replaceable assemblies are the Air-
craft Interface PWA, the Audio Compressor PWA, the Acquisition Processor PWA, and
the Crash Survivable Memory Unit (CSMU).
When it has been determined that one or more of these assemblies is faulty, the faulty
assembly(ies) should be removed and returned to the Aviation Recorders factory for re-
pair or replacement. Attempts to repair any of these assemblies will void the warranty.
Extreme care should be used when handling these assemblies.
