Incident Overview
The aircraft had been stored outdoors since its last annual inspection on December 1, 1984. After purchasing the aircraft, a pilot who holds an Aircraft and Powerplant (A&P) maintenance technician certificate examined it. A ferry permit was issued by the Federal Aviation Administration (FAA) for the planned ferry flight to the pilot's home base.
Mechanical Issue
Unbeknownst to the pilot, the main fuel line to the rear engine was partially blocked by foreign material. This blockage permitted adequate fuel flow for sustained static operation at 1000–1500 RPM, as well as a brief burst of power at full throttle. However, it was insufficient for sustained high power settings.
Flight and Landing
During the initial climb, the rear engine's power decreased to a level between 1200 and 1500 RPM. The pilot was unable to maintain flight and directed the aircraft toward the nearest available landing site. While pulling up to avoid trees at the edge of the site, the aircraft lost flying speed. It then mushed to a touchdown, resulting in a hard landing.
