Aircraft Accident/Incident Report
Mekoryuk, Alaska 99630
Monday, December 3, 2012 10:50 AST
NTSB Narrative Summary Released at Completion of Accident
Shortly after the scheduled commuter flight departed with the second-in-command (SIC) at the controls, the engine "coughed," started vibrating, and lost power. The SIC attempted to restart the engine, but was unsuccessful. Subsequently, the pilot-in-command assumed control of the airplane and landed on a frozen bay, which resulted in substantial damage to the airplane's right wing and fuselage. A postaccident examination of the airplane's engine revealed that one of the first-stage compressor blades had fractured due to fatigue cracking. The source of the fatigue crack could not be determined due to secondary damage sustained to the fracture surface.
NTSB Probable Cause Narrative
The total loss of engine power as a result of a fractured first-stage compressor blade due to fatigue cracking. The source of the fatigue crack could not be determined due to secondary damage sustained to the fracture surface.
