Aircraft Accident/Incident Report

Iliamna, Alaska 99606
Saturday, February 5, 2000 16:00 AST

NTSB Narrative Summary Released at Completion of Accident

The airplane impacted level terrain, covered by smooth, wind-blown, snow, in a left bank of 26 degrees or greater. The leading edge of the first impact crater was angled 15 degrees below the horizon. The area surrounding the wreckage for about one mile was featureless, snow-covered, tundra. Beyond one mile, were rising hills with areas of exposed vegetation. Visible and infrared satellite images displayed a band of bright cloud tops and thick clouds, which traversed the flight path of the accident airplane between the departure airport, 27 miles to the east, and the accident site. Similar reflective images existed over a weather reporting station with visibility of one mile in light snow and mist, and overcast ceilings of 1,100 feet. The airplane's heading at the time of impact was in the direction of the departure airport. The GPS receiver was providing navigation information to the original destination at the time of impact. The airplane was equipped with basic flight instruments, and the pilot was required by the company to demonstrate his ability to control the airplane by reference to those instruments. No evidence of any preimpact mechanical anomaly was discovered with the airplane.

NTSB Probable Cause Narrative

The pilot's attempted flight into adverse weather, and his failure to maintain altitude/clearance above the snow-covered tundra. Factors associated with the accident were snow, rain, and whiteout conditions.
