The pilot reduced engine power to idle; however, the airplane encountered a “hole,” causing the left main landing gear to collapse. A postaccident inspection revealed that the left elevator had struck a Precision Approach Path Indicator (PAPI) light. The left wing was also damaged, resulting in substantial damage to the airplane. The pilot stated that there were no failures or malfunctions with the airplane prior to the accident. Recorded winds in the vicinity of the accident airport were from the south at 6 knots. However, southerly winds with gusts to 16 knots had been recorded prior to the accident. ## Factual narrative The pilot stated that during the takeoff roll, “a strong wind gust from the left caused me to lose control and veer off the runway.” The airplane temporarily became airborne over the grass area adjacent to the runway.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
