Aircraft Accident/Incident Report

Nabesna, Alaska 99586
Friday, September 18, 2009 14:00 AKD

NTSB Narrative Summary Released at Completion of Accident

The pilot was departing from a rough and uneven 800-foot-long remote airstrip in a tundra tire-equipped airplane. The pilot said that after assessing his passenger's weight, coupled with the southerly light and variable winds, he elected to depart to the south. He said that just after takeoff the wind suddenly switched to a tailwind and the airplane stopped climbing. The airplane then collided with a stand of trees and brush at the departure end of the site, sustaining substantial damage to the wings and empennage. The pilot noted that there were no preaccident mechanical anomalies with the airplane.

NTSB Probable Cause Narrative

The pilot's selection of an unsuitable takeoff area with an unfavorable wind.
