Safety record

Accident & incident history

1998-06-16 Accident · Pacific Ocean, PO Damage: Destroyed Fatal injury NTSB · LAX98LA200
Reported aircraft: Hughes 369HS — a different aircraft that carried the N95MS registration before this airframe.
Probable cause: The improper shimmying of the tail rotor driveshaft by maintenance personnel which induced fatigue in the tail rotor driveshaft coupling causing it to fail, which resulted in a loss of tail rotor control. A factor is the failure of the pilot to recognize the warning vibrations indicating impending failure of the coupling.
1997-03-11 Accident · Pacific Ocean, PO Damage: Destroyed NTSB · LAX97LA120
Reported aircraft: McDonnell Douglas MD 369HS — a different aircraft that carried the N95MS registration before this airframe.
Probable cause: A loss of engine power due to a deteriorated compressor air seal, which resulted from inadequate maintenance inspection of the helicopter to detect corrosion in the compressor case while being operated in a marine environment.
