Amateur-built GN 1 AIRCAMPER N437PT accident near Defuniak Springs, Florida

Probable cause

The pilot's loss of directional control during the landing in gusting crosswind conditions resulting in a runway excursion, and the pilot's failure to attain a positive climb rate during the aborted landing and subsequent ground collision.

NTSB analysis

According to the pilot of the tailwheel-equipped airplane, during the landing roll, the airplane encountered a crosswind gust and he applied right rudder. He reported that a subsequent wind gust lifted the right wing, triggering a ground loop to the right and the airplane exited the right side of the runway. He recalled that the airplane was headed for a water drainage catch basin and he decided to add full power, and attempt to fly out of the ground loop in an effort to avoid the catch basin. The right wheel of the airplane collided with the perimeter of the catch basin and the airplane spun to the right. The airplane sustained substantial damage to the left wing lift strut.

According to the nearest meteorological aerodrome report, 19 miles south, the wind about the time of the accident was variable at 3 knots. The pilot landed on runway 27.
