Accident Sequence
According to the pilot's report, during the takeoff roll and initial climb, the aircraft had ascended to approximately 500 feet above ground level when the engine power suddenly decreased. The engine RPM dropped from 2600 to 2100. Subsequently, the aircraft began descending and struck trees before crashing roughly three-quarters of a mile from the departure end of the runway.
Preflight Inspection
Days before the flight, the fuel tanks had been fully serviced. During the preflight inspection, the pilot checked the fuel tanks and the gascolator for water or contamination, and none was found. The aircraft was deemed ready for flight.
Investigation Findings
Post-accident examination of the airframe and engine revealed no evidence of any preimpact part failure or mechanical malfunction. The investigation did not identify any specific component that contributed to the loss of engine power. The cause of the power reduction remains undetermined from the available evidence.
