Détails:
The flight crew reported that, after an instrument landing system approach and during the landing flare, the airplane encountered a strong wind gust that pushed the airplane toward the edge of the runway, so they initiated a go-around. During the go-around, the left-wing tip tank struck the runway. The flight crew diverted to another airport where the weather conditions were more favorable, and after landing, examination of the airplane revealed that the left wing had sustained substantial damage. The calculated crosswind component was 18 knots at the time of landing. According to the Airplane Flight Manual, the maximum demonstrated crosswind component was 24.7 knots.

Probable Cause:

PROBABLE CAUSE: "The pilot flying's improper lateral bank control during a go-around in gusting wind conditions, which
resulted in the left-wing tip tank striking the runway."
