What happened
The pilot was operating a light aircraft for his first solo cross-country flight. During the landing phase at touchdown, the airplane bounced upon contact with the runway surface and began to porpoise, oscillating vertically. On the third bounce, the nose wheel fork failed structurally. Following this mechanical failure, the aircraft turned 180 degrees to the left and came to rest on the left side of the runway. The incident resulted in structural damage to the firewall and the airframe.
The investigation
The examination focused on the mechanical failure of the landing gear during the bounced landing sequence. The investigation confirmed that the nose wheel fork failed during the third bounce of the porpoising motion. Subsequent inspection revealed significant structural damage to the firewall and the airframe caused by the impact and the resulting 180-degree turn.
Findings
The primary factor in this accident was the failure of the nose wheel fork during a bounced landing. The sequence of events began with the airplane bouncing at touchdown, which led to porpoising. The structural integrity of the nose gear could not withstand the forces of the third bounce, leading to immediate failure and loss of directional control. The aircraft then turned left and sustained damage to the airframe and firewall.
Safety message
Pilots should be aware that bounced landings can place excessive stress on landing gear components. Proper technique to avoid bouncing is critical, especially during solo flights where experience may be limited. Monitoring for signs of porpoising after initial touchdown is essential to prevent structural failure.
