Aircraft involved

Probable cause & findings

The pilot's loss of directional control during the takeoff roll, which resulted in a runway excursion, ground loop, and impact with terrain. Contributing to the accident was the pilot's lack of experience from the back seat.

Factual narrative

The pilot of the tailwheel equipped, tandem cockpit airplane, who was sitting in the rear seat, reported that during the takeoff roll, the airplane veered off the left side of the runway and ground looped. The airplane sustained substantial damage to the right wing. The pilot reported no preimpact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation. The pilot reported that he did not have any experience piloting a tailwheel equipped airplane from the rear seat and he could not see the instruments with the passenger seated in the front seat.
