Analysis

The pilot stated that he began his takeoff from the very beginning of the runway, and that on rotation, the engine seemed to lose power. He stated that he observed the tachometer and saw that the engine was dropping below 1500 RPM. Subsequently, the aircraft struck the top's of trees about 150 ft from the departure end of the runway. The aircraft then crashed into the bank of a dry creek about 400 ft from the runway. A disassembly of the engine revealed no preimpact malfunction of failure.
