Analysis

The pilot was landing the airplane on his 1,500-foot grass airstrip. During the landing, the airplane bounced and the pilot aborted the landing. As power was applied, the airplane moved to the left side of the runway into trees and the airplane came down on a workshop roof south of the runway substantially damaging the fuselage. The pilot reported no mechanical malfunctions or failures with the airplane that would have precluded normal operation.
