Aircraft Accident/Incident Report

Togiak, Alaska 99678
Thursday, May 2, 1996 8:30 AKD

NTSB Narrative Summary Released at Completion of Accident

The certificated commercial pilot was conducting flight operations in support of fish spotting activities and was departing a remote beach at gross weight. The pilot reported that frost was present on the wings of the airplane and he began a short field takeoff. The airplane lifted off sluggishly and then began to settle toward the ground that was sloping toward the ocean. At full power, the airplane touched down momentarily and then climbed into the air. The airplane skipped off the water about three times and the pilot aborted the takeoff. The airplane settled into the water and stopped in a nose down attitude.

NTSB Probable Cause Narrative

The pilot's failure to remove frost from the surface of the wings and his delay in aborting the takeoff. Factors in the accident were the presence of frost on the wings and a deteriorated climb performance.
