Accident & incident history

1998-07-30 Accident · Nondalton, AK Fatal injury NTSB · ANC98LA112
Reported aircraft: de Havilland DHC-2
Probable cause: The pilot's inadequate procedures/directives when he allowed a passenger to exit the cabin area while the propeller was still turning, and the passenger's failure to follow the pilot's instructions to stay away from the propeller. A factor associated with the accident is the passenger's unfamiliarity with aircraft.
