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. ## Factual narrative The pilot of the homebuilt Pitts Model 12 airplane stated that he overflew the airport from the east and observed the windsock was indicating a 90-degree crosswind for the airport's runway, designated 36/18.
