Accident & incident history

1. DCA20LA100Apr 20, 2020Camp Dwyer, OFSerious

   Fatigue cracking of the auxiliary servo cylinder’s pedal damper check valve housing and its bolts, which caused the sudden and uncommanded movement of the helicopter’s left pedal and a subsequent left yaw that continued until ground impact. Contributing to the accident were (1) the nonconforming edge of the pedal damper check valve housing during manufacture and (2) Sikorsky’s lack of a specific inspection for the pedal damper check valve housing.
