He was aware that, about five yards from the edge of the airstrip, there was a line of irrigation pipes supported by ten foot diameter metal rotation wheels, but he thought that allowing the aircraft to weathervane into the crosswind would keep him over the airstrip. Therefore, after liftoff he allowed the aircraft to weather vane toward the irrigation pipes. Soon thereafter the wind shifted, and the aircraft flew into one of the ten foot support wheels before the pilot could take corrective action. In the recommendations section of the NTSB Form 6120.1, the pilot stated that he was in a rush, and that he should have taken the time to move over to an adjacent field that was away from the irrigation system. ## Factual narrative The pilot, who was taking off in a powered-lift, weight-shift controlled, light sport aircraft, was departing from a grass airstrip in gusting crosswind conditions.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
