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 homebuilt airplane stated that he overflew the airport from the east and observed that the windsock was indicating a 90-degree crosswind of 15-20 knots for the airport's runway, designated 36/18. The pilot elected to land on runway 36 and entered the downwind leg of the traffic pattern. The pilot reported inputting a "significant" amount of slip to maintain centerline during final approach and flare. The airplane touched down on the right main landing gear first and then bounced off the grass strip. During the bounce, the crosswind forced the airplane toward the left, off the runway, and into a fence where the left wingtip struck a fence post. The airplane yawed, the wing hit the ground, and the airplane cart-wheeled, coming to rest inverted.
