The NTSB's narrative final · quoted from the NTSB record
The pilot completed two full stop solo landings on runway 26 and aborted the third. He realized the winds had '...picked up somewhat with occasional gusts on the third approach.' He stated about his last approach that 'at flare/touchdown a gust caused the aircraft to become airborne and turn to the left.' The pilot said he applied power to attempt a go around and the 'airplane continued [its] left turn, [and] then began descending.' He said the left main landing gear contacted the ground, which caused the aircraft to ground loop and the 'aircraft came to rest facing north in the center of the grass runway 18/36.' The pilot listed damage to the nose gear, right main landing gear, propeller, engine mount, both outboard wing tips, and horizontal stabilizer. An on-scene examination of the accident airplane did not reveal any preimpact anomalies. Wind at General Mitchell International Airport, Milwaukee, Wisconsin was 340 degrees at 13 knots gusts to 20 knots.
