Aircraft Accident/Incident Report

Bethel, Alaska 99559
Saturday, September 6, 1997 19:00 AKD

NTSB Narrative Summary Released at Completion of Accident

The pilot and three passengers were departing a remote, private airstrip. The airstrip is 1,000 feet long and 40 feet wide, at an elevation of 1,200 feet mean sea level. It is located in a narrow canyon with steep terrain on the north side, and lower hills on the south side. During the takeoff on a magnetic heading of 130 degrees, the airplane lifted off near the end of the runway. The pilot indicated that after lift-off the airplane climbed to about 50 feet above the ground, and suddenly encountered a downdraft. The airplane began descending toward the ground, and collided with rough terrain. The pilot indicated the wind conditions at the time of the accident were 040 degrees at 20 knots, with gusts to 25 knots.

NTSB Probable Cause Narrative

The pilot's inadequate evaluation of the weather conditions. Factors in the accident were a downdraft, crosswind conditions, and rough/uneven terrain.
