Aircraft Accident/Incident Report

Igiugig, Alaska 99613
Thursday, April 13, 2000 14:30 AKD

NTSB Narrative Summary Released at Completion of Accident

The certificated private pilot was attempting a southeasterly departure from an 800 feet long sand bar. He stated that the takeoff run required a correction for a strong left crosswind. During the takeoff run, as the airplane became airborne, a strong gust of wind pushed the airplane to the right, and over an area of soft snow. He said that when the wind decreased, the airplane's main wheels contacted the soft snow, and the airplane nosed over. The airplane sustained substantial damage to the wings and fuselage. The pilot reported wind conditions at the time of the accident to be from the east at 20 knots, with peak gusts to 40 knots.

NTSB Probable Cause Narrative

The pilot's intentional flight into known adverse weather. Factors associated with the accident were the variable crosswind conditions, and the pilot's inadequate compensation for those wind conditions.
