The commercial pilot, with two passengers, was preparing to land following a Title 14, CFR Part 91 personal flight. The pilot said that as the airplane descended to about 1,000 msl, all engine power was lost. In an attempt to restore engine power, he switched the airplane's fuel tank selector valve from the "both" position to the "left", then to the "right" position, and back to "both." The pilot noted that he did not activate the airplane's auxiliary fuel pump while he was switching fuel tanks. The pilot selected a small open area that was surrounded by trees and power lines for a forced landing. During the landing approach, the airplane collided with the power lines and trees, receiving substantial damage to the wings, fuselage, and empennage. The accident airplane's maximum fuel capacity is 84 gallons, with 78 gallons of usable fuel. The unusable fuel is 6 gallons, or 3 gallons per side. During an on-site postaccident inspection, about 6 gallons of fuel was drained from the right fuel tank, and about 1.5 gallons of fuel from the left fuel tank. A postaccident engine examination revealed that the brass, fuel control-mounted mixture control lever, was loose on the mixture control shaft. The mixture control shaft was in the closed (off) position. Once the fuel control shaft was manually moved to the open position, the engine was started and operated at various power settings for an extended time. The engine produced its full rated rpm. According to an FAA airworthiness inspector, the accident airplane was about 10 months overdue for an annual inspection, and the mixture control linkage is an item required to be checked during the annual inspection.
Probable Cause: A total loss of engine power during descent due to a loose mixture control linkage, and the pilot/owner's failure to maintain the airplane's annual inspection schedule, which resulted in a forced landing in an area that contained power lines and trees.
