## Analysis

ACCORDING TO THE PLT, ACFT PREFLIGHT, ENGINE RUNUP AND WARM UP WERE NORMAL. TAKEOFF AND INITIAL CLIMB UP TO APPROX 300 FT AGL WERE NORMAL ALSO. AT THIS POINT THE ENGINE QUIT AND THE PLT PERFORMED A FORCED LANDING IN A CLOVER FIELD BELOW HIM. THE ACFT WAS SUBSTANTIALLY DAMAGED DURING THE FORCED LANDING. FOLLOWING THE ACCIDENT THE ENGINE WAS TEST-RUN ON A TEST BENCH UP TO 2500 RPM. THE ONLY DISCREPANCY NOTED WAS THAT THE ENGINE RAN ROUGH ON THE LEFT MAGNETO.
