Probable cause

The loss of directional control on the ground and the pilot's inadvertent ground loop. A factor was the failure by the pilot of the conflicting traffic on the runway to maintain proper traffic separation.

Sequence of events

Analysis

During the takeoff roll the pilot observed another aircraft begin a takeoff from the opposite direction. The pilot aborted the takeoff; however, he lost control and the aircraft ground looped.

Factual narrative

On October 10, 1994, at 1230 central daylight time, an Air Tractor AT-502, N133HF, was substantially damaged during an aborted takeoff at Lamesa, Texas. Visual meteorological conditions prevailed and no flight plan was filed for this aerial application flight. The commercial pilot was uninjured.

During an interview conducted by a Federal Aviation Administration inspector, and in his written statement, the pilot stated that he was halfway down the runway when he aborted takeoff due to conflicting traffic in position to takeoff from the opposite direction. During the abort, the pilot lost directional control and ground looped the aircraft.

The aircraft sustained damaged to the empennage, wings, and fuselage.
