What happened
The aircraft experienced a nose-over incident during the landing phase. According to the pilot, the touchdown was slightly hard, and the aircraft struck a bump on the runway surface. This impact resulted in the failure of the left shock cord.
The investigation
Following the event, the pilot provided an assessment of the mechanical failure. He noted that while the landing was firm, he did not believe the force was sufficient to cause immediate structural failure under normal conditions. Instead, he suggested that the gear had been fatigued due to repeated operations from unimproved landing sites.
Findings
The primary factor in this accident was the collapse of the landing gear. The pilot's statement indicates that the left shock cord broke upon impact with a bump during touchdown. The condition of the gear is attributed to operational history rather than a single excessive force event.
