Accident Details
During the final approach, after lowering the landing gear, the pilot received an unsafe gear indication. He flew past the control tower, and the controller confirmed that the landing gear appeared to be down. The pilot then recycled the landing gear and received a normal gear-down indication. Upon touchdown, the right main landing gear collapsed, causing the aircraft to slide off the runway into the grass.
Investigation Findings
A post-crash investigation revealed no evidence of broken components. Inspection of the aircraft maintenance records showed that the left and right main landing gear downlocks had been adjusted two flights prior to the incident. Additionally, it was learned that during the flight prior to this occurrence, the right main landing gear fell into a hole while the aircraft was taxiing.
Maintenance History
The maintenance records indicated that the downlock adjustments were performed two flights before the collapse. The earlier incident where the right main gear fell into a hole during taxiing may have affected the gear's integrity, though no direct causal link is stated in the source.
