The airplane sustained substantial damage to the fuselage. The pilot did not report that there were any preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. The pilot failed to submit the NTSB Pilot/ Operator Aircraft Accident/ Incident Report Form 6120.1.
