Analysis

While on a short local flight to a costal area and return. The engine lost some power. Carburetor heat was applied but no increase in power was noted. The plt then set up a glide with intentions of making a landing onto the beach area. At about 500 feet m.s.l. power was resumed and the plt elected to climb to 2,000 feet m.s.l. with the intentions of returning to the departure airport. Over rugged treed terrain a power loss was again noted. Application of carburetor heat had no effect upon the engine. A forced landing was made into tall hay. Inspection of the engine revealed that the engine compartment carburetor air heat control lever was broken with the control cable disconnected and the hot air door jammed in the cold position.
