What happened
The pilot recently acquired the aircraft and possessed only six hours of flight time in tailwheel-equipped airplanes. During the approach for landing, the aircraft bounced once upon initial contact with the runway surface. Following this bounce, the aircraft touched down just to the left of the runway centerline.
As the aircraft moved along the pavement, it began to veer toward the left side of the runway. In an attempt to maintain directional control and correct the deviation, the pilot applied right rudder input. This overcorrection caused the aircraft to turn sharply to the right. The sudden change in orientation resulted in the aircraft turning sideways relative to the direction of travel. Under these conditions, the left main landing gear collapsed.
The investigation
The investigation focused on the mechanical failure of the landing gear and the sequence of events leading to the collapse. Examination confirmed that the structural integrity of the left main gear was compromised due to the lateral forces generated during the sideways turn. No pre-existing mechanical defects were identified as the primary cause of the failure.
Findings
Contributing factors included the pilot's limited experience with tailwheel aircraft and the decision-making process during the landing roll. The initial bounce reduced tire traction, making directional control more difficult. The subsequent overcorrection exacerbated the loss of control, leading to the gear collapse. The proximity to the runway centerline at touchdown also played a role in the lateral instability.
Safety message
Pilots with limited experience in tailwheel aircraft should exercise extreme caution during landing operations. Proper technique for handling bounces and maintaining directional control is critical. Overcorrection can lead to loss of control and structural damage. Adequate training and supervision are essential for mastering these skills.
