Analysis

The uncertificated pilot was landing a tailwheel-equipped airplane, with one passenger at a remote, rough and uneven off-airport site, at the completion of a Title 14, CFR Part 91, business flight. Witnesses noted that during the landing roll the airplane's right main wheel struck a log, and the right main landing gear collapsed. The right wing and right horizontal stabilizer struck the ground. The airplane sustained substantial damage to the right wing, right wing lift struts, empennage, and fuselage. Due to the remote location the airplane has not been examined by the NTSB.
