Analysis

The CFI and dual student were on initial takeoff after the student had successfully handled a simulated right engine failure on takeoff roll. Shortly after takeoff, the left engine quit. The CFI took control, but was unable to clear trees off the end of the runway. The airplane collided with the trees before impacting the ground. An inspection of the aircraft fuel system revealed presence of some silicone-type material in the left fuel tank. This material stopped up a hand pump used to empty the fuel tank at the accident site. After the accident, the left engine was successfully run with an alternate fuel system, and no abnormalities were found.
