What happened
The commercial pilot attempted to land the aircraft in conditions characterized by significant wind shear. The reported wind was from 270 degrees at 23 knots, with gusts reaching up to 32 knots. During the landing roll, the strong crosswind component lifted both the left wing and the tail section of the plane. This aerodynamic lift caused the aircraft to lose directional control, leading it to skid off the runway to the right side.
The aircraft ultimately entered a drainage ditch adjacent to the runway surface. The impact with the terrain resulted in substantial structural deformation. The tail section was bent upwards upon impact. Additionally, the nose, engine mount, and firewall were all bent upwards due to the force of the excursion.
The investigation
Post-accident examination revealed extensive damage consistent with a high-energy runway excursion into soft or uneven terrain. The upward bending of the tail, nose, engine mount, and firewall indicates that the aircraft struck the ground with significant vertical and forward momentum after leaving the paved surface. The specific orientation of the damage suggests the aircraft settled into the ditch rather than bouncing off it.
Findings
The primary factor contributing to this accident was the strong crosswind conditions present during the landing phase. The combination of a 23-knot wind with gusts to 32 knots created a challenging environment for maintaining directional control on the runway. The pilot's inability to counteract the lateral force resulted in the skid off the runway and subsequent ditching.
Safety message
Pilots operating in high-wind conditions must remain vigilant for gusty crosswinds that can exceed reported averages. Maintaining directional control during the landing roll requires precise rudder and aileron input to counteract sudden wind shifts. Understanding the limits of aircraft controllability in such weather is critical to preventing runway excursions.
