Introduction
An aircraft that had been inactive for eight years was being ferried to the pilot's facilities for rebuilding. The ferry flight encountered multiple engine failures, leading to a forced landing that resulted in structural damage.
Flight and Engine Failures
During cruise flight, the right engine ceased operation and the propeller could not be feathered. The aircraft was unable to maintain altitude in that configuration, prompting the pilot to initiate a forced landing. While descending, the left engine also quit.
The aircraft subsequently impacted soft terrain. The landing gear collapsed, and the lower fuselage sustained damage.
Maintenance and Permit Status
The last annual inspection of the aircraft had been conducted in 1982. The ferry permit issued for the flight had expired two weeks prior to the accident. Before the flight, a fuel tank was changed, and the pilot applied tape on the filler cap.
Post-Accident Findings
Examination of the aircraft's fuel system after the accident revealed that the left fuel tanks were empty. Additionally, the right outboard tank line was blocked. The right outboard tank had been selected when the right engine quit.
