Sequence of Events
During the upwind leg after the fourth or fifth touch-and-go landing, the engine experienced a total loss of engine power due to fuel starvation. The flight instructor (CFI) took the controls and landed the airplane on the runway, but there was insufficient runway remaining to stop. During the landing roll, the engine power was restored, and the CFI elected to take off to return for landing.
During the subsequent upwind leg, the engine again experienced a total loss of engine power due to fuel starvation. During the left turn to return to the airport, the airplane stalled and impacted the ground with the nose and left wing low.
Fuel Selector and Tank Contents
The fuel selector was positioned to the left tank for the duration of the flight. The left fuel tank was empty. The right fuel tank contained 15.4 gallons of fuel.
