Analysis

The pilot reported that at the conclusion of a Title 14, CFR Part 91 personal flight, he landed his tailwheel airplane on a hard-surfaced runway. During the landing roll, he said he lost directional control, and the airplane ground-looped to the right, damaging the left wing, left aileron, and left elevator. The pilot indicated the wind was 5 to 8 knots and variable in direction. He noted that had he been more aware of its variable direction, he would have slowed his taxi speed and anticipated a possible wind shift. He said there were no preaccident mechanical problems with the airplane.
