Analysis

During takeoff, the eng lost power as the acft was climbing thru aprx 400 ft. the plt made a 180 deg turn to land back on the arpt. However, he then realized that the acft would not reach the rwy, so he turned & landed in a swamp area. An exam of the eng revealed that the #3 cylinder had failed. No fatigue was found in the fracture area. There were indications that the cylinder had failed from overload, but the reason for the overload was not verified.
