A pilot executed a precautionary landing in an alfalfa field after losing power on one engine. The aircraft sustained damage during the gear-up touchdown, though no mechanical malfunction was found.

What happened

The aircraft experienced a loss of power on its engines during flight. The pilot managed to restore power on only one engine and subsequently initiated a precautionary landing in an alfalfa field located away from the airport. Prior to ground contact, the landing gear was not extended.

After the accident, the pilot reported that he had attempted to switch the fuel selector in an effort to restore power, but this action was unsuccessful. Upon inspection following the incident, it was determined that the aircraft still contained approximately 25 gallons of fuel on board. A thorough examination revealed no malfunction in the aircraft systems.

The investigation

The investigation focused on the mechanical condition of the aircraft and the pilot's actions during the emergency. Inspectors examined the engine systems to determine if a mechanical failure contributed to the power loss. They also reviewed the fuel quantity remaining after the event.

Findings

  • Partial engine failure occurred, with power restored on only one engine.
  • The aircraft landed in an alfalfa field off the airport.
  • The landing gear was not extended before ground contact.
  • The pilot attempted to switch the fuel selector but was unsuccessful.
  • Approximately 25 gallons of fuel remained on board after the accident.
  • No malfunction in the aircraft systems was found.

Safety message

Pilots should be aware that even with remaining fuel, partial engine failures can occur. Proper emergency procedures, including gear extension and fuel system management, are critical during such events.

Probable cause

The pilot's failure to extend the landing gear prior to touchdown, which resulted in damage to the aircraft. The cause of the initial power loss was undetermined as no mechanical malfunction was found despite approximately 25 gallons of fuel remaining on board.
