A-87-086
NTSB Safety Recommendation — Aviation
Recommendation text
TO THE FEDERAL AVIATION ADMINISTRATION: Develop a technical standard order (TSO) for solid-state flight data recorders (SFDR) specifying resolution, sampling intervals, accuracies, and specify crash/fire survivability requirements to accommodate the unique design characteristics of the SFDR not currently covered by TSO c-51a. Also provide specific criteria by which the ability of the recorder to retain the most recent 25 or 8 hours recorded data can be verified. (Supersedes Safety Recommendations A-78-028, A-82-064 through A-82-067, A-82-106 through A-82-111) (Superseded by A-92-46 through A-92-48)
In plain language (FlightFinder summary)
The Federal Aviation Administration is asked to develop a technical standard order (TSO) for solid-state flight data recorders (SFDR) that specifies resolution, sampling intervals, accuracies, and crash/fire survivability requirements, since current TSO c-51a does not cover the unique design characteristics of SFDRs. Additionally, the FAA must provide criteria to verify that the recorder can retain the most recent 25 or 8 hours of recorded data.
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.
