Aircraft Accident/Incident Report
Naknek, Alaska 99633
Friday, May 19, 2006 7:30 AKD
NTSB Narrative Summary Released at Completion of Accident
The private certificated pilot was in cruise flight about 1,000 feet above ground level (agl), when the engine began to lose rpm. The pilot said the engine gauges appeared to be normal, but the rpm kept decreasing. The pilot said he performed all emergency procedures, including application of carburetor heat, but the airplane could not sustain level flight. He turned toward a remote airstrip, and prepared for an emergency landing. The pilot said the airplane collided with alders and then bounced off the ground, coming to rest near the end of runway 13 at the airstrip, facing the opposite direction of flight. The airplane received structural damage to the fuselage, empennage, and wings. The pilot was unable to determine what precipitated the loss of engine power, and the engine was not examined by NTSB or FAA personnel.
NTSB Probable Cause Narrative
A loss of engine power during cruise flight for an undetermined reason, which resulted in a forced landing and subsequent collision with high vegetation and the ground.
