What happened
While operating in clouds at a cruise altitude of 7,000 feet, the pilot of the Cessna (registration not provided) experienced an engine surge followed by a loss of power approximately 30 minutes into the instrument flight. In response to the power loss, the pilot switched fuel tanks and activated the electric fuel pump; however, the fuel gauge indicated no fuel pressure, and the engine failed to regain full power. The pilot did not apply carburetor heat during the event. After declaring an emergency with air traffic control, the pilot attempted an emergency landing, during which the aircraft collided with trees.
The accident resulted in no fatalities (based on provided text), though the impact caused significant damage to the airframe. Post-accident examination revealed that the fuselage was buckled and both wing assemblies had separated from the fuselage.
The investigation
A post-accident examination of the aircraft was conducted, which revealed no mechanical or flight control anomalies. The investigation also included a review of Advisory Circular 20-113 regarding procedures for suspected induction system icing.
