The pilot was familiarizing himself with the airplane in preparation for a multi-day cross-country flight. He also said that there was a potential that he would provide flight instruction to a student during the upcoming flights, so he wanted to perform three takeoffs and landings in the airplane to meet the recent flight experience requirements of Title 14 Code of Federal Regulations Part 61.57. He said that as he approached the airport, the reported weather indicated the wind was aligned with the runway. During the approach, he noted that the windsock showed a left crosswind, and he adjusted the approach using crosswind control correction for the left crosswind. During the rollout, the wind shifted, and the right wing rose. The pilot attempted to correct but when the wing came back down the airplane veered off the left side of the runway and the right main landing gear collapsed. He said that after the event the windsock showed a right crosswind and he believed that there was some windshear that resulted in the right wing raising during the event. The airplane received substantial damage to the right wing. The pilot reported that there were no mechanical issues with the airplane. The recorded weather at the airport where the accident occurred was from 020° at 3 knots, about the time of the accident.
