Incident Summary
A pilot reported that during initial climb, the engine lost power, resulting in the aircraft striking trees. The three passengers on board stated that the pilot did not complete a weight and balance calculation prior to departure. They noted that the pilot neither asked their individual weights nor weighed their baggage.
Pilot Report
The pilot indicated that the engine power loss occurred shortly after takeoff, during the initial climb phase of flight. The subsequent descent led to a collision with trees.
Passenger Statements
Passengers recounted that no weight and balance procedure was performed. When their actual weights and baggage were later computed, the aircraft was found to be 233 pounds over its maximum takeoff gross weight of 2,500 pounds. One occupant reported hearing the stall warning horn just before the aircraft struck the trees.
Examination Findings
Examination of the airplane did not disclose any evidence of mechanical malfunction with the engine or any other part of the aircraft. No preexisting defects were identified that could explain the loss of engine power.
