service testing using factory procedures for all
FA2100 CVRs. L-3AR Repair Station is the only authorized Repair
Station to use the L

112 compliant Model FA2100CVR has been de-
signed as a maintenance-free unit. The Model FA2100CVR is considered an “ON
CONDITION LRU.” Each of its printed wiring assemblies (PWAs) makes extensive
use of surface mount technology (SMT). The repair of a PWA containing SMT de-
vices requires specialized training and factory equipment, along with special trouble-
shooting and soldering techniques; therefore, L-3 Communications, Aviation Record-
ers has deemed that PWAs containing SMT devices are not to be repaired in the
field. As a result, the Model FA2100CVR’s maintenance philosophy is to level-2
board replacement.
The FA2100CVR, has four field replaceable assemblies: (1) the Aircraft Interface
PWA, which contains the power and input circuits; (2) the Audio Compressor PWA,
which conditions the audio streams into digital formats for recording; (3) the Acquisi-
tion Processor PWA, which contains the processing and control circuits; and (4) the
Crash Survivable Memory Unit (CSMU), which is used to digitally store and crash
protect the cockpit voice communications. When it has been determined that an as-
sembly is faulty, it should be removed from service, properly packaged, and returned
to L3 Communications, Aviation Recorders for repair or replacement. No trouble-
shooting procedure is provided for any of these assemblies. Attempting field repair
on any of these assemblies will void their warranty.
