Plain English Summary

2/10 complexity

What this does: This is a mandatory safety directive requiring inspection and potential repair of pilot and co-pilot seats in specific Sikorsky S-76 helicopters due to manufacturing defects in the seat support frames.

Who it affects: Operators of Sikorsky S-76 helicopters fitted with AMI Industries seats (part numbers 1078-1 and 1078-3) that have serial numbers listed in the manufacturer's Service Bulletin No. 25-S76-1.

What must be done: Operators must inspect the seat support frames by 9 May 1981 (or before the next flight if the helicopter is already flying after this date) to check for defective tube support members. If defects are found, repairs must be carried out strictly following the procedures in AMI Industries Service Bulletin No. 25-S76-1.

Why it matters: Defective seat support members could fail during an accident, hard landing, or turbulence, potentially injuring the flight crew or preventing them from properly controlling the aircraft.
