Accident Overview
During a training flight, a certified flight instructor (CFI) and a dual student were conducting a simulated right engine failure during the takeoff roll, which the student successfully handled. Immediately after the actual takeoff, the left engine ceased operation. The CFI assumed control of the aircraft but was unable to clear trees located at the end of the runway. The airplane subsequently collided with the trees before impacting the ground.
Post-Accident Examination
An inspection of the aircraft's fuel system revealed the presence of a silicone-type material within the left fuel tank. This material was found to have obstructed a hand pump that was used to empty the fuel tank at the accident site. After the accident, the left engine was successfully operated using an alternate fuel supply system, and no abnormalities were detected during this test.
Conclusion
The investigation identified silicone-type contamination in the left fuel tank but did not determine the exact cause of the engine failure. No other anomalies were found in the engine or fuel system.
