Aircraft Accident/Incident Report

Palmer, Alaska 99645
Saturday, July 18, 1998 18:28 AKD

NTSB Narrative Summary Released at Completion of Accident

The float equipped airplane was reported by the pilot to be in cruise flight about 800 feet above the surface of a glacier. He estimated the gross weight of the airplane at 3,312 pounds. He was flying in an up-glacier direction, in a mountainous valley. The prevailing winds at the surface were reported by the pilot to be 15 knots in a down-glacier direction. The pilot stated that the airplane began to descend rapidly, and that full power did not arrest the descent. The Cessna U206G performance charts indicate a climb rate between 915 and 1,005 feet per minute given the prevailing conditions. The pilot said there were no mechanical problems with the airplane, and that he did not attempt to turn because the most favorable landing terrain was ahead of the airplane. The airplane collided with slightly rising terrain, in a wings level, nose up attitude, just as the stall warning horn activated. The airplane sustained substantial damage. There were no injuries to the four occupants.

NTSB Probable Cause Narrative

The pilot's inadequate compensation for wind conditions, and inadequate clearance from mountainous terrain. Factors were the downslope winds and downdrafts.
