SERVICE INFORMATION LETTER
DATE: March 11, 2015
Letter No. FA2100CVR 037
TO:
USERS OF THE MODEL FA2100CVR COCKPIT VOICE RECORDER
SUBJECT:
NEW CONFORMAL COATING PROCESS FOR ACQUISITION PRO-
CESSOR CIRCUIT CARD ASSEMBLY (CCA)
To Whom It May Concern,
As of January 2015, all part numbers of L
−
3 Communications Model FA2100 Cockpit Voice
Recorders manufactured will contain a new conformal coating process on the Acquisition
Processor CCA.
L-3 Communications has introduced this new conformal coating process on all configura-
tions of the Acquisition Processor Circuit Card Assemblies (CCA’s) to improve their mois-
ture resistance and mitigate pending obsolescence of the incumbent coating.
As this is a process change only, not affecting any form, fit or function aspects of the Model
FA2100 CVR, no external modification identification will be implemented. However,
through L-3 AR’s internal serialization and as built manufacturing system, we are tracking
all Serial Numbers that have the new process CCA’s incorporated.
Sincerely
L‐3 Communications, Aviation Recorders
Mike Phillips
Product Support Manager
