What happened
During a ferry flight intended to relocate an aircraft that had remained grounded for several years, the crew experienced a sudden loss of propulsion. While the aircraft was maintaining an altitude of 7,500 feet, the pilot attempted to transition from the primary tanks to the auxiliary fuel supply. Immediately following the adjustment of the fuel selectors to the auxiliary position, both engines ceased functioning and failed to restart.
In an attempt to avoid a more catastrophic impact, the pilot performed an emergency landing on a roadway. During the descent and touchdown, the aircraft's wings made contact with several mailboxes and posts before the plane ultimately collided with a dirt embankment. Despite the impact, both occupants escaped without injury.
Findings
Investigations into the incident revealed that the primary factor in the dual engine failure was fuel contamination, as evidenced by the discoloration and impurities found in fuel samples. Additionally, the investigation identified deficiencies in the recent annual inspection performed on the aircraft prior to the flight. The pilot's preflight procedures were also noted as inadequate, contributing to the overall sequence of events that led to the loss of power.
