NTSB Safety Recommendation — Aviation
Recommendation text
THE NTSB RECOMMENDS THAT THE FEDERAL AVIATION ADMINISTRATION: ISSUE A MAINTENANCE ALERT TO PRINCIPAL MAINTENANCE INSPECTORS TO INSPECT SEATBELT ATTACHMENT SHACKLES INSTALLED ON PASSENGER SEATS ON AIR CARRIER, AIR TAXI, AND COMMERCIAL AIRPLANES TO VERIFY THAT THE CORRECT BOLTS ARE USED TO FASTEN THE SHACKLES TO THE SEATS, THE BOLTS ARE TORQUED TO CORRECT VALUE, AND THE SHACKLES ARE FREE TO SELF-CENTER AFTER THE CORRECT TORQUE HAS BEEN APPLIED TO THE BOLTS.
In plain language (FlightFinder summary)
The NTSB asks the FAA to issue a maintenance alert directing principal maintenance inspectors to inspect seatbelt attachment shackles on passenger seats in air carrier, air taxi, and commercial airplanes. The inspections must confirm that the correct bolts are used, that bolts are torqued to the correct value, and that the shackles can self-center after proper torque is applied.
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.
