Probable cause

The pilot's improper landing flare, which resulted in a long landing and subsequent loss of directional control, and his subsequent failure to attain sufficient altitude to clear trees during an attempted go-around.

Findings · 5

NTSB’s coded findings. Those marked are part of the probable cause; the rest are factors or other findings. Under each, the cases with the same finding.

Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot reported that, during landing on a remote, unimproved airstrip, he overshot the touchdown point by about 150 ft. During the landing roll, the airplane veered right, and he decided to go around. During the takeoff climb, he pulled up because he realized that the airplane was not going to be able to clear trees, and the airplane aerodynamically stalled. The left wing dropped and struck trees, and the airplane spun 180° and impacted the ground. The airplane sustained substantial damage to both wings, the empennage, and the fuselage. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.

Factual narrative

The pilot in the tailwheel-equipped airplane reported that during landing on a remote unimproved airstrip, he overshot his touch down point about 150ft. During the landing roll the airplane veered to the right side of the runway and he decided to go-around. During the takeoff climb, he "pulled up when I saw that I was not going to clear trees," and the airplane aerodynamically stalled. The airplane's left wing descended and struck trees, and the airplane spun 180° and impacted the ground. The airplane sustained substantial damage to both wings, the empennage and the fuselage. The pilot reported that there were no mechanical malfunctions or failures with the airplane that would have precluded normal operation.
