Analysis

The private pilot was using his single-engine airplane to conduct an aerial survey of his ranch when he noted a trough that was overflowing. He elected to land at the nearby 1,100-foot-long dirt airstrip so that he could fix the water problem. During landing, the pilot encountered a gust of wind and the airplane bounced, traveling beyond the point where an aborted landing could be safely achieved due to a row of power lines. The pilot first applied brakes, which caused the tail to rise, but not enough to slow the airplane down to a full stop. He then applied full brakes, subsequently flipping the airplane over and resulting in damage to both wings and the vertical stabilizer.
