What happened
The incident occurred while the aircraft was preparing for departure. The pilot had successfully completed the engine run-up procedure and was in the process of taxiing toward the runway when the right main landing gear suddenly collapsed. This structural failure prevented further movement under its own power.
The investigation
Following the accident, recovery personnel were able to manually cycle the landing gear mechanism, successfully returning it to a down-and-locked position for safe removal of the aircraft. A thorough mechanical examination was conducted on the landing gear system to determine the root cause of the collapse.
Findings
The post-accident inspection revealed that none of the landing gears were in the down-and-locked position prior to the collapse. Despite this critical configuration error, the mechanical examination found no mechanical anomalies within the landing gear system itself. This suggests the failure was likely due to improper setup or indication rather than a hardware malfunction.
