Event Description
The pilot reported that 1-2 seconds after landing on runway 21, a 'bang' was heard, followed by the right wing dropping and the airplane ground looping to the right. The event resulted in substantial damage to the wing and fuselage.
Examination Findings
Upon inspection of the right landing gear strut, the pilot observed that the right wheel had separated from the strut leg. Examination of the bolts that attached the wheel to the strut revealed that one bolt had fractured, and the other two were stripped of their respective nuts.
Maintenance Compliance
The pilot stated that the bolts installed on the wheel were not in compliance with a recent service bulletin that recommended a higher tensile strength bolt.
