## Analysis

THE ACFT COLLIDED WITH THE GROUND IN A CORN FIELD DURING A SIMULATED FORCED LANDING AFTER THE POWER FAILED TO RESPOND TO FULL THROTTLE. THE ACFT HAD BEEN DESCENDED FROM 3000 FT AGL WITH THROTTLE AT IDLE, FULL FLAPS AND CARBURETOR HEAT ON. IN TURNING 180 DEGREES AT ABOUT 300 FT AGL THE CFI RAISED THE FLAPS AND THE STALL WARNING HORN CAME ON. THE ACFT DEVELOPED A HIGH SINK RATE AND THE CFI REACHED TO ADVANCE THE THROTTLE BUT FOUND IT ALREADY ADVANCED. THE ENGINE REPORTEDLY DID NOT RESPOND AND THE ACFT DESCENDED TO THE GROUND. AFTER THE ACCIDENT THE ENGINE WAS TEST RUN AND IT RAN ROUGH ON LEFT MAG. IT WAS FOUND TO BE WORN IN THE DISTRIBUTOR BLOCK AND BEARINGS.
