NTSB narrative
During landing roll, the twin-engine airplane's right main landing gear collapsed. The pilot reported that during takeoff, as the airplane lifted off the ground, he heard a 'bump.' Then as the landing gear retracted, just before reaching the up and locked position, he heard a 'loud bang.' The pilot proceeded to his intended destination. At the destination, when the landing gear was lowered, the right main landing gear green light did not illuminate. The pilot raised the landing gear and heard another 'loud bang.' The pilot then elected to return to his departure airport. The pilot performed flybys at an en route airport and at the destination airport to confirm a problem with the right main landing gear. The pilot initiated a slow approach to runway 36, and when landing was assured, shut down both engines. The airplane touched down, and during the landing roll, the right main landing gear collapsed. An examination of the right main landing gear by an A & P mechanic with an FAA Inspection Authorization (IA), revealed that the 'gear torque tube support bracket/pivot bearing broke allowing the gear down lock tube to break by overtorquing.'
Probable cause
The failure of the right main landing gear torque tube support bracket/pivot bearing which resulted in the failure of the landing gear locking mechanism.

- 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: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
