Analysis

The acft collided with the terrain during a forced landing following a loss of engine power. The plt indicated that he retarded the throttle and applied the carburetor heat to descend from 3,000 to 2,000 ft when the engine quit. He was unable to restart the engine because the acft was not equipped with an electrical starting system. He landed the acft in a field with rough/soft surface conditions collapsing the landing gear and causing substantial damage to the acft's fuselage. The plt also indicated that there were no mechanical failures or malfunctions. The acft's engine was examined and no cause for the loss of power was determined.
