Probable cause

The pilot's inadequate short-field landing procedure and excessive airspeed that resulted in a landing overrun. Contributing to the accident were gusting unfavorable winds, the short runway, and rocks off the departure end of the strip.

Findings · 6

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

While landing at a 1,000-foot-long remote dirt airstrip, the pilot encountered gusting variable winds. He said that while focusing on compensating for those winds, he failed to slow the airplane sufficiently. After touchdown, the airplane ran off the end of the airstrip, encountered rocks, and nosed over onto its back.

Factual narrative

During the landing roll at a 1,000 foot long remote dirt airstrip, the pilot encountered gusting winds that varied in the their direction. While focused on compensating for the unfavorable winds, the pilot failed to slow the airplane sufficiently to ensure that it could be stopped prior to reaching the end of the airstrip. The airplane therefore overran the end of the airstrip, impacted a number of large rocks, and flipped over onto its back. The accident sequence resulted in damage to the top of the vertical stabilizer, and a permanent bend in both of the lift struts on the left side of the airplane.
