Event Overview
A commercial pilot, who was the recent owner of the aircraft, was conducting a flight to obtain a tailwheel endorsement and a flight review. After completing some air work, the flight returned to the airport to practice landings. The commercial pilot was at the controls for a full stall landing.
Landing Sequence
The aircraft touched down straight but then began a slight turn to the right. The commercial pilot called for the instructor to take control, which the instructor did. However, corrective inputs were unsuccessful in realigning the aircraft to the runway heading.
Landing Gear Failure
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.
Post-Accident Inspection
An inspection of the left main landing gear revealed that two wedges were missing. Additionally, the retaining screws on the left side were found to be 1/8 of an inch further out compared to the right side, where the wedges were still in place.
