What happened
The pilot was conducting an approach to land when monitoring the Automated Weather Observing System (AWOS). The weather data indicated winds from 290 degrees at 8 knots with gusts reaching 20 knots. The aircraft touched down on runway 36, with the left main landing gear making initial contact. After the right main landing gear was lowered, a sudden gust of wind elevated the left wing. This aerodynamic shift caused the aircraft to turn toward an easterly heading. It departed the runway, crossed a taxiway, and entered a ravine where it came to rest in an inverted position.
The investigation
The physical evidence confirmed that the aircraft sustained significant structural damage consistent with a rollover event. The final resting place was inside a ravine adjacent to the airport infrastructure. No mechanical failures were identified as contributing factors prior to the loss of control.
Findings
The primary factor in this accident was the crosswind component during landing. The pilot attempted to land on runway 36 despite wind gusts exceeding the steady-state wind speed by a significant margin. The timing of the gust coincided with the critical phase of gear extension and weight transfer, leading to an asymmetric lift condition that resulted in the loss of directional control.
Safety message
Pilots must carefully evaluate wind conditions during approach and landing. Sudden gusts can significantly alter aircraft handling characteristics, especially when one wing is lifted or during gear transition. Adhering to crosswind limits and being prepared for rapid weather changes is essential for safe operations.
