A pilot took off from a mountain airport near maximum gross weight in gusty winds. After reaching 200 feet, the airplane encountered downdrafts, turned back, touched wheels, then left wing struck terrain, resulting in a cartwheel.

Accident Sequence

The pilot initiated a takeoff from a mountain airport. After becoming airborne, the airplane climbed to approximately 200 feet above ground level. As it flew over mountainous terrain, the airplane encountered downdrafts and began to sink. The pilot executed a turn back toward the airport. During the turn, the airplane continued to descend. Prior to reaching the airport, the wheels briefly contacted the terrain, but the airplane regained flight. Almost immediately thereafter, the left wing struck the ground, causing the airplane to cartwheel into the terrain. No evidence of engine or flight control anomalies was found.

Aircraft Loading and Conditions

According to Federal Aviation Administration calculations, the airplane was loaded to within about 50 pounds of its maximum gross weight. The density altitude at the mountain airport was approximately 8,000 feet, and winds were gusting to 14 knots at the time of takeoff.

Pilot Statement

The pilot stated that the way to prevent such an accident from recurring is "To not fly in the mountains when the gross weight is close to the maximum."
