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 flare, the airplane encountered a "sudden massive gust of wind" that pitched the nose up. He pushed the yoke forward, but the wind shifted to a tailwind, and the airplane "slammed" onto the runway. Subsequently, the left main landing gear collapsed, the airplane veered right off the runway, and it then came to rest nose down. The airplane sustained substantial damage to the left wing. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. The automated weather observation system at the airport reported that, about the time of the accident, the wind was from 260° at 4 knots. The pilot landed on runway 26.
