NTSB narrative
The pilot was unable to obtain cockpit landing gear down-and-locked indications while on a visual approach to the destination airport. After repeated attempts to actuate the emergency landing gear extension system, he was still unable to obtain a gear down-and-locked indication. He overflew the airport so that air traffic control personnel could observe the landing gear position, which was observed as extended. The pilot then attempted a landing, during which the right main landing gear collapsed, and the airplane veered off the runway and hit a runway sign. During the repair of the landing gear system, several components exhibited a lack of lubrication, which resulted in the landing gear failing to lock when extended. Once the components were cleaned, lubricated, and adjusted, the landing gear functioned normally. The airplane and landing gear system were last inspected and repaired about 8 months prior to the accident during which adequate lubrication of the landing gear components should have been confirmed.
Probable cause
The collapse of the right main landing gear during landing due to a lack of component lubrication, which resulted in the failure of the landing gear to lock once extended.

- 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.
