Analysis

According to the pilot, while conducting a low altitude pass over an off-airport site with a 5 to 7 mph tailwind in his tailwheel-equipped airplane, the landing gear contacted a patch of alder brush. The airplane subsequently came to rest in an area of tall brush, both wings, lift struts and empennage sustained substantial damage. The pilot reported no pre-impact mechanical malfunctions or failures with the airplane that would have precluded normal operation.
