The defining event best describes what happened. - [Landing-landing roll: Landing gear collapse](https://openairdocs.org/ntsb-events/094) (defining event); cases with it: [Cessna 195, 6 cases](https://openairdocs.org/ntsb-events/094/sequence.md?model=2073102), [All aircraft, 1,787 cases](https://openairdocs.org/ntsb-events/094/sequence.md) ## Analysis The pilot reported that 1-2 seconds after landing on runway 21, he heard a 'bang', then the right wing dropped, and the airplane ground-looped to the right, substantially damaging the wing and fuselage. Upon examination of the right landing gear strut, he 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 fractured and the other two were stripped of their respective nuts. 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. ## Factual narrative The pilot reported that 1-2 seconds after landing on runway 21, he heard a 'bang', then the right wing dropped, and the airplane ground looped to the right substantially damaging the wing and fuselage.
