Probable cause

The pilot’s failure to maintain aircraft control during landing. Contributing to the accident were the crosswind wind conditions and terrain induced turbulence.

Findings · 4

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

As the pilot began flaring for landing at a private airstrip, the airplane encountered sudden turbulence and immediately rolled to the right. Despite the pilot’s attempt to counteract the roll and abort the landing, the right wing struck the surface of runway 24 and the airplane began to cartwheel. The airplane came to rest upright adjacent to the runway. The pilot noted that at the time of the accident the wind was from 210 degrees at 20 knots. Examination of the airplane by the pilot revealed that both wings were structurally damaged. The pilot stated that there were no mechanical anomalies with the engine, airframe, and flight control system at the time of the accident. The owner of the private airstrip stated that due to the location of a residential structure, it is common to experience turbulence near the approach end of runway 24 during high wind conditions.
