Sequence of Events
A private pilot, who was receiving instruction for a tailwheel endorsement, was conducting touch-and-go landings. During the takeoff climb of the third or fourth touch-and-go, the engine lost power and began to sputter. At the time of the power loss, the fuel selector was positioned to the left fuel tank.
Prior to the flight, the cockpit fuel sight gauges indicated the left fuel tank was approximately three-quarters full, and the right fuel tank was approximately half full. After the engine lost power, the flight instructor initiated a forced landing to a field. During the forced landing, the airplane impacted trees and terrain, and came to rest on its nose.
Post-Accident Examination
Examination of the airplane revealed that the fuel system was intact. The left main fuel tank was empty, while the right main fuel tank contained "plenty of fuel." The fuel was clear of contaminants. No other anomalies were noted.
