Analysis
During the planned termination of an instructional proficiency flight in his tailwheel-equipped airplane, the pilot attempted a full-stop landing in a nearly direct crosswind that was gusting to 15 knots. During the landing roll, the pilot failed to maintain directional control and the flight instructor providing dual instruction did not take action in time to remedy the situation. The airplane therefore veered sharply off the runway surface, and during the excursion sequence its right wing contacted the ground and sustained structural damage.
