What is "wingstrike"

Wingstrike is contact between an aircraft's wing and the ground during takeoff or landing, most often as a complication of a crosswind landing.

Unexpected gusts of wind may cause an aircraft to roll to one side or the other during landing, whether they are performing a crosswind landing or not.

However, crosswind landings have a much more complex dynamic relationship between the wind and the aircraft attitude. Because the wind is blowing across the runway, the aircraft has to either roll or yaw into the wind to be able to approach down the runway's centerline. As the aircraft transitions from descent to touchdown, the roll and/or yaw have to be countered to land smoothly and stay on the runway. This transition can cause upsets, particularly in gusting wind.

Damage from wingstrike can range from replacement of wing surface skin areas at the wingtip, to structural damage throughout the wing due to overloads.
