Aircraft Accident/Incident Report
Skwentna, Alaska 99667
Sunday, August 21, 2005 13:00 AKD
NTSB Narrative Summary Released at Completion of Accident
The commercial pilot was conducting a 14 CFR Part 135 on-demand passenger flight to a remote, dirt airstrip at a lodge, when he said the airplane began to sink rapidly on final approach. The pilot said he added power, but the airplane touched down short of the runway, collided with a stump, and came to rest inverted. He said there were no known mechanical anomalies with the airplane prior to the accident, but felt the throttle may not have responded appropriately when he added throttle to arrest the descent rate. After deplaning the passengers, the pilot returned to the airplane and checked the throttle, which appeared to function normally. The airplane received structural damage to the wings and fuselage.
NTSB Probable Cause Narrative
The pilot's misjudged distance/altitude on final approach, which resulted in a noseover following an undershoot and in-flight collision with rough/uneven terrain. A factor associated with the accident was the rough/uneven terrain.
