Incident
A flight instructor was evaluating a pilot receiving instruction in a tailwheel-equipped, high performance airplane during a visual flight rules (VFR) cross-country flight. The instructor reported that they considered the runway to be "a one-way strip." Upon arrival at the private airstrip, the GPS indicated a 5-knot crosswind from the southeast.
During the approach, the airplane was about "50 ft high" when it crossed the predetermined go-around point. On touchdown, the airplane bounced twice, and the pilot initiated a go-around. The instructor then "reminded" the pilot that they were committed to the landing and instructed him not to go around, so the pilot transitioned the airplane back to landing.
During the subsequent touchdown, the airplane "quickly" veered right. The pilot attempted to correct the veer, but the airplane exited the right side of the airstrip, encountered soft ground, and nosed down, coming to rest on the spinner and left wing.
Damage and Findings
The airplane sustained substantial damage to the left wing. The flight instructor reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. The pilot indicated that the wind at the airport was about 140° at 5 knots, and the pilot was landing on runway 5.
Pilot and Instructor Actions
The flight instructor recommended that he should have taken the controls sooner in the abnormal situation.
