First Takeoff Attempt
A private pilot was being instructed in flying a tailwheel-equipped airplane by a commercial pilot seated in the right seat. The commercial pilot did not hold a flight instructor certificate. During the initial takeoff roll, the airplane veered to the left. After stopping, one of the tailwheel centering springs was found disconnected. The spring was reconnected.
Second Takeoff Attempt
The pilots swapped seats, taxied back to the runway, and attempted another takeoff. During the takeoff roll, the airplane again veered left, departed the runway, and struck a fence.
Postaccident Examination
A postaccident inspection of the airplane revealed that the attachment point for the right rudder cable was bent forward, causing slack in the cable.
Pilot Qualifications
Neither pilot was current to carry a passenger in a tailwheel-equipped airplane. Additionally, the commercial pilot did not possess a current FAA medical certificate or a current biennial flight review.
