The NTSB's narrative final · quoted from the NTSB record

The aircraft was modified by STC to a conventional landing gear configuration. The pilot reported that he did not sufficiently reduce the airspeed during the approach and the aircraft 'bounced about 2-3 feet' on the touchdown. At that point, the seat slid backwards about 3 to 4 inches and the pilot stated that the abrupt seat movement caused his loss of control. The aircraft then ground looped, turned approximately 90 degrees, and came to a stop upright on the runway. Aircraft maintenance records disclosed that Airworthiness Directive 87-20-03R2, which pertains to the inspection of the seat tracks, had been complied with. The pilot reported to an FAA inspector that he had forgotten to engage the seat locking pin before the flight.
