Incident Overview
During a dual primary instructional flight, the flight instructor reported that after completing airwork in a nearby practice area, the aircraft returned to the airport for touch-and-go traffic pattern operations. On the third touch-and-go landing roll, the instructor stated that he depressed the brakes and felt and heard the right landing gear 'give.' The right main landing gear subsequently collapsed, with the strut puncturing the wing.
Witness Reports
Ground-based witnesses at the airport reported that on the second touch-and-go prior to the incident, the aircraft made a 'very noticeable hard landing.' No further details about the severity or outcome of that landing were provided.
Examination Findings
An FAA airworthiness inspector examined the aircraft and reported that the bolts which secure the landing gear strut to the wing spar appeared to have failed in shear. No other information about the condition of the aircraft or components was disclosed.
