Analysis

While on final apch, the plt added power but the eng did not respond. After touchdown in a field short of the rwy. The lt main landing gear separated & punctured the fuel tank. The acft was destroyed by fire. Exam of the eng compartment revealed that a bolt which secures the mixture & throttle bellcranks to the bellcrank support assy, failed due to fatigue. This prevented throttle control input in the cockpit from activating the carburetor.
