Aircraft Accident/Incident Report
Tuluksak, Alaska 99679
Tuesady, April 25, 2006 18:35 AKD
NTSB Narrative Summary Released at Completion of Accident
The certificated airline transport pilot was departing on a Title 14, CFR Part 135, on-demand air taxi passenger flight from a 2,461 foot-long slush and snow-covered gravel runway. The pilot reported that the airplane became airborne after using about two-thirds of the runway, but would not climb. Once the airplane passed over the departure end of the runway, it stalled and collided with a stand of trees and snow-covered terrain. The airplane sustained structural damage to the wings, fuselage, and horizontal stabilizer. The pilot said that there were no preaccident mechanical anomalies with the airplane. A postaccident investigation revealed that the estimated gross weight of the airplane at takeoff was about 2,485 pounds, or approximately 185 pounds in excess of the maximum takeoff gross weight of 2,300 pounds.
NTSB Probable Cause Narrative
The pilot's inadvertent stall/mush during takeoff-initial climb, which resulted in an in-flight collision with trees and terrain. Factors associated with the accident were the pilot's excessive loading of the airplane, his inadequate preflight planning, and a slush-covered runway.
