Incident Overview
During takeoff, the pilot reported a significant drop in engine power at approximately 500 feet of altitude. Despite applying full power, the engine surged several times before the pilot executed a forced landing in an open field. The aircraft sustained damage during the landing.
Post-Accident Examination
An FAA-certificated airframe and powerplant mechanic with inspection authorization examined the accident aircraft. The mechanic inspected the fuel, ignition, and induction systems, reporting no anomalies. A subsequent engine test run was performed, operating the engine up to 1,700 rpm, during which the engine functioned normally.
Pilot Statement
The pilot stated that during the climb, she noticed a large power drop. She maintained full power and observed the engine surging multiple times before choosing to land in a nearby field.
Conclusion
The mechanic's inspection and test run did not reveal any mechanical defects that could explain the power loss. The cause of the power drop remains unconfirmed based on available information.
