Probable cause

The pilot's failure to maintain adequate airspeed during the approach, which resulted in a rapid descent rate, hard landing, and nose-over.

Findings · 3

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 the landing approach to a ridgeline airstrip, he deployed full flaps and descended to the touchdown point. About 15 ft above ground level, the airplane started to descend, which he failed to recognize and arrest. The pilot added that the approach speed was also a little too slow for the unstable air, which likely increased the descent rate. Subsequently, the airplane touched down hard short of the touchdown point, nosed over, and came to rest inverted. The left wing and empennage were substantially damaged. 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 reported that during the landing approach to a ridgeline airstrip, he deployed full wing flaps and descended to the touchdown point. About 15 ft above ground level, the airplane encountered a sink that he failed to recognize and arrest. The pilot further remarked that the approach speed was also a little too slow for the unstable air which likely increased the rate of descent. The airplane touched down hard, short of the touchdown point, and nosed over, coming to rest inverted. The left wing and empennage were substantially damaged. The pilot reported no mechanical anomalies with the airplane that would have precluded normal operation.
