What happened
The pilot reported conducting an approach to land on the runway under conditions involving a moderate crosswind. As the aircraft descended to approximately three feet above the runway surface, the wind speed decreased significantly or reversed direction entirely. This sudden change in wind conditions caused the airplane to bounce upon contact with the ground. During this bounce, the shifting wind began to turn the aircraft laterally. The pilot was unable to maintain directional control as the airplane turned, resulting in a ground loop that inflicted substantial damage to the airframe.
The investigation
The investigation relied primarily on the pilot's statement regarding the sequence of events during the final approach and landing phase. No mechanical failure or pre-landing anomaly was identified by the pilot prior to the wind shift. The primary factor examined was the interaction between the aircraft's ground handling characteristics and the rapidly changing wind environment.
Findings
The accident was caused by the pilot's inability to maintain directional control during a landing in gusty crosswind conditions. Specifically, the sudden loss or reversal of wind at low altitude led to an uncommanded bounce and subsequent turn that exceeded the pilot's ability to correct. The resulting ground loop placed excessive stress on the landing gear and fuselage, leading to substantial damage.
Safety message
Pilots should be aware that sudden changes in wind speed or direction during the final stages of landing can cause unexpected aircraft behavior. Maintaining adequate control authority and being prepared for rapid corrections is essential when operating in variable wind conditions near the ground.
