Analysis

The pilot was landing a tailwheel and tundra tire-equipped airplane at an off-airport site. Just before touchdown he felt the airplane sink, and added power to correct the condition, but the airplane hit hard and bounced. He recovered from the bounce, and brought the airplane to a full stop. The airplane sustained substantial damage to the fuselage. The pilot reported no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
