Analysis

During IFR cruise, a loss of power occurred. The pilot complied with emergency procedures for power loss but when he reached down to switch the fuel tank selector he lost control of the aircraft and entered into a nose down unusual attitude, descending at the rate of 2,500 feet per minute. During recovery, the aircraft broke out of clouds at 1200 feet AGL. During attempt to land on a curving road, the pilot was forced to avoid power lines. A hard landing resulted. Investigation revealed a loose carburetor heat housing clamp, restricting travel of the carb heat control and that automotive/mixed fuel was being used.
