NTSB Safety Recommendation — Aviation
Recommendation text
SINCE A CVR WILL NOT OPERATE PROPERLY WITH A SPLIT-RING CONNECTOR AND BECAUSE OF THE IMMENSE VALUE OF THE CVR RECORD IN AIRCRAFT ACCIDENT INVESTIGATIONS, THE NTSB RECOMMENDS THAT THE FEDERAL AVIATION ADMINISTRATION: ISSUE AN AIRWORTHINESS DIRECTIVE (AD) MAKING MANDATORY AN INSPECTION (AS SOON AS PRACTICAL DEPENDING ON AVAIL ABILITY OF SPARE UNITS AND THE CAPABILITY TO REPLACE THE DEFECTIVE UNITS) FOR INCORRECT SPLIT-RING SOCKETS SPECIFIED IN SUNDSTRAND DATA CONTROL SERVICE BULLETIN DOCUMENT NO. 012-0296-109, DATED JANUARY 25, 1982, TITLED "COMMUNICATION -- COCKPIT VOICE RECORDERS/MODELS AV-557A, AV-557B, AND AV-557C/TAPE DECK HOUSING CONNECTOR CHECK," AND REQUIRE REPLACEMENT OF INCORRECT CONNECTORS AT THE EARLIEST POSSIBLE DATE.
In plain language (FlightFinder summary)
The NTSB asks the FAA to issue an Airworthiness Directive (AD) requiring inspection, as soon as practical, for incorrect split-ring sockets specified in Sundstrand Data Control Service Bulletin No. 012-0296-109 (January 25, 1982), and to mandate replacement of any incorrect connectors at the earliest possible date, because a cockpit voice recorder (CVR) will not operate properly with a split-ring connector, and the CVR recording is critically important for aircraft accident investigations.
This plain-language summary is written by FlightFinder to explain the recommendation above. It is not the official wording — the verbatim NTSB text is quoted above.
