NTSB narrative
The airplane's left main landing gear collapsed while taxiing after landing. The pilot reported he had 3 green lights and that the landing was normal. He taxied for about 2,000 feet and started a right turn onto a taxiway when the landing gear collapsed. An inspection of the accident site revealed that the distance between where the propeller had struck the runway and where the aircraft came to rest was approximately 120 ft. An examination of the landing gear revealed that the only visible damage to the left main landing gear system was a sheared AN25-38A bolt which attached the rod end of the bellcrank to the lower side brace, and the NAS464P4-26 bolt which attaches the upper portion of the bellcrank to the upper portion of the upper barrel. The aircraft inspection revealed the right main landing gear operated, but the left landing gear could not be operationally checked.
Probable cause
The landing gear collapsed for undetermined reasons.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: local date, investigation status. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2002-07-24.
