A-82-106
NTSB Safety Recommendation — Aviation
Recommendation text
TO THE FEDERAL AVIATION ADMINISTRATION: Encourage timely adoption of the Society of Automotive Engineers (SAE) standard for "general aviation" flight recorders (intended for installation in multiengine, turbine powered fixed-wing aircraft and rotorcraft in any type of operation not currently required by 14 CFR 121.343, 121.359, 135.151, and 127.127 to have a cockpit voice recorder and/or a flight data recorder), and issue a technical standard order (TSO) covering such recorders immediately after the SAE document is approved. Include in the TSO requirements that: (a) specify a cockpit voice recorder (CVR) of high enough audio quality to render intelligible recorded data on each of two channels which reserves one channel for voice communications transmitted from or received in the aircraft by radio, and one channel for audio signals from a cockpit area microphone; (b) specify all flight data recorder (FDR) parameters, ranges, accuracies, and sampling intervals cited in tables I and II; (c) specify crash and fire survivability standards for CVRs and FDRs which are at least as stringent as those of tso-c51a for type I (nonejectable) and type iii. (Superseded by A-87-77 through -89) (Urgent)
In plain language (FlightFinder summary)
The Federal Aviation Administration is asked to encourage the adoption of a new SAE standard for flight recorders in general aviation aircraft not already required to have them, and to issue a Technical Standard Order (TSO) after the standard is approved. The TSO must specify audio quality and channel requirements for cockpit voice recorders, parameters for flight data recorders, and survivability standards at least as stringent as existing TSOs.
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.
