Aircraft Accident/Incident Report

Sparrevohn, Alaska 99567
Thursday, September 14, 2000 15:30 AKD

NTSB Narrative Summary Released at Completion of Accident

The certificated commercial pilot started a southwesterly takeoff run from a 1,500 feet long, remote sand bar. Just after lift-off, as the airplane started to climb, a strong gust of wind from the right lifted the right wing, and rolled the airplane about 90 degrees. As he applied full right aileron to correct for the roll, the airplane's wings leveled, but that it was in an uncontrolled decent. The airplane continued to descend and struck an embankment. It sustained substantial damage to the wings, wing lift struts, and fuselage. The pilot said that there were no preaccident mechanical anomalies with the airplane.

NTSB Probable Cause Narrative

The pilot's inadequate compensation for wind conditions. Factors associated with the accident were variable winds, and a crosswind.
