What happened
The pilot had just completed a landing from a business flight. During the landing roll, a strong wind gust originating from the left side caused the aircraft to turn unexpectedly to the left. In response, the pilot applied full power to regain control. However, the aircraft continued to depart the runway to the left.
The pilot then attempted to correct by turning the aircraft back to the right. This maneuver caused the aircraft to cross the runway and subsequently depart the runway to the right side. During this departure, the right main gear struck the edge of a concrete taxiway, causing damage to that gear. The aircraft then swerved further to the right, leading to the collapse of the left main landing gear.
The investigation
The investigation focused on the mechanical failure and the sequence of events during the landing roll. It was determined that the strong wind gust from the left was the primary factor initiating the loss of directional control. The subsequent actions taken by the pilot, including applying full power and turning right, contributed to the aircraft crossing the runway and striking the taxiway edge.
Findings
The collapse of the left main landing gear was a direct result of the swerving motion after the right main gear struck the concrete taxiway edge. The initial loss of control was attributed to the strong wind gust from the left during the landing roll. The pilot's response, while intended to correct the situation, led to further departure from the runway and subsequent structural damage.
Safety message
Pilots should be aware of the potential for sudden wind gusts during landing roll and the importance of maintaining directional control. Proper use of rudder and brake inputs, rather than relying solely on power adjustments, may help prevent similar incidents in crosswind conditions.
