Aircraft Accident/Incident Report
Glennallen, Alaska 99588
Thursday, September 5, 2013 19:54 AKD
NTSB Narrative Summary Released at Completion of Accident
The pilot departed a remote, off-airport site to search for a moose he had shot earlier in the day. A witness observed the airplane perform a series of low-altitude maneuvers before flying by his location about 80 to 100 feet above the ground. The airplane then began a left turn, and the nose of the airplane pitched down abruptly and began to spin. The airplane subsequently descended vertically, nose first, and it collided with the tundra and brush-covered terrain.
A postaccident examination of the airframe and engine revealed no mechanical malfunctions or anomalies that would have precluded normal operation.
Given the lack of mechanical deficiencies with the airplane and engine, the witness statements, and the nature of the damage to the airplane, it is likely that the pilot inadvertently stalled and spun the airplane at a low altitude and was unable to recover.
NTSB Probable Cause Narrative
The pilot’s failure to maintain adequate airspeed while maneuvering at a low altitude, which resulted in an aerodynamic stall/spin and impact with the ground.
