The NTSB's narrative final · quoted from the NTSB record
The purpose of the flight was for the commercial pilot, the owner who recently purchased this aircraft, to get a tailwheel endorsement and flight review. After completing some air work, the flight returned to the airport to practice landings. The commercial pilot was at the controls for the full stall landing. The aircraft touched down straight, then started a slight turn to the right. The commercial pilot called for the instructor to take control, which he did. Corrective inputs were unsuccessful to realign the aircraft to runway heading. The left main landing gear eventually failed and separated from the structure. The aircraft came to rest on the side of the runway with the left wing contacting the surface. Inspection of the left main landing gear found that two wedges were missing and that the retaining screws were 1/8 of an inch further out than the right side, where the wedges were still in place.
