- Date: July 11, 2009
- Aircraft: Noorduyn Norseman
- Location: Akiachak, Alaska, United States
- Fatalities: 0
- Phase of flight: Approach and landing
- Cause: Loss of engine power from the failure of a crankshaft component, leading to an off-airport landing.
A Part 135 passenger flight in a 1944 Norseman lost engine power in cruise after a loud bang and rough running. The pilot tried to reach an airport but the engine seized and he came down short of the runway, damaging both wings and the fuselage. The NTSB traced the failure to a crankshaft counterweight that had come loose after a locking screw backed out.
