Probable cause

The pilot’s improper airspeed and pitch control during landing in variable, gusting wind conditions, which resulted in an aerodynamic stall and hard landing.

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 the approach to the desert airport, the wind had increased to about 15 knots, and it was gusting. He reported that, during landing, "a gust of wind hit me from the opposite direction of flight causing a stall." The airplane stalled about 8 ft above the runway and landed hard. The airplane sustained substantial damage to the engine mounts. The METAR at the nearest airport (7 miles from accident airport) reported that, about the time of the accident, the wind was from 210° at 4 knots. An hour later, the METAR reported that the wind was 10 knots, gusting to 17 knots. 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 approach to the desert airport, the wind had increased to about 15kts and gusting. During landing, he reported that, "a gust of wind hit me from the opposite direction of flight causing a stall." The airplane stalled about 8ft above runway 18 and landed hard. The airplane sustained substantial damage to the engine mounts. The METAR at the nearest airport reported that about the time of the accident, the wind was from 210° at 4kts and the temperature was 95°F. The field elevation was 725ft and the density altitude was 3,315ft. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
