He did a mental checklist, and thought that the landing gear was down; however, it was not. The airplane subsequently landed with the landing gear retracted, which resulted in substantial damage to the fuselage. The pilot reported no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation. ## Factual narrative The pilot reported that during the sixth and final landing of the day, he was aware of another airplane in the landing pattern that disrupted his routine.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
