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 of the tailwheel-equipped airplane reported that, during the landing in a crosswind, a strong wind gust lifted the right wing. Subsequently, the airplane exited the left side of the runway, traveled down an embankment, and 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. A review of recorded data from the automated weather observation station located on the airport revealed that, about 15 minutes before the accident, the wind was from 280° at 11 knots, gusting to 17 knots. The pilot landed on runway 22.
