The NTSB's narrative final · quoted from the NTSB record
During the landing roll in a right crosswind, the tailwheel airplane had slowed to 25 mph when it veered to the right and groundlooped. There was a hard shimmy and vibration, and the airplane turned 110 degrees at which point the left main wheel and axle separated from the airframe. The pilot had one hour in the make and model of aircraft. The FAA airworthiness inspector found that the threads from the 'top two nuts and one lower nut were stripped from their bolts holding the axle on the landing gear.' The last annual inspection was performed on 9/1/97. The FAA airworthiness inspector stated that the 'appearance of the aircraft is a generally neglected condition, with worn door hinges, poor operating door latches, fogged instrument glass, and corrosion in plain view.' Maintenance records were not submitted to the Safety Board for review.
