What happened
During a positioning flight conducted under Federal Aviation Regulation Part 91, the pilot reported an unsafe nose gear down indication prior to attempting to land. Despite the warning, the aircraft proceeded with the landing sequence. Upon touchdown, the nose gear collapsed, resulting in damage to the aircraft.
The investigation
Following the incident, a thorough examination of the landing gear assembly was conducted to determine the cause of the failure. The inspection revealed no evidence of any pre-existing mechanical malfunction within the gear system itself. However, detailed analysis of the bearing ends, specifically part number 452-412, showed clear signs consistent with an overload failure.
Findings
The primary factors contributing to this incident include the N600TS experiencing a nose gear collapse during landing and the subsequent overload failure of the bearing components. The absence of mechanical malfunction suggests that the failure was likely induced by the forces applied during the landing event rather than a pre-landing defect.
