Analysis

During cruise flt at 3,000 ft, 20 miles south of the intended destination, the plt reported that smoke filled the cockpit. About 1 minute later the eng seized. During the attempted forced landing on a water filled phosphate pit, the acft collided with an embankment short of the pit, nosed over and came to rest inverted. Exam of the eng revealed that the number 4 cylinder piston was damaged circumferentially for undetermined reasons. Also discovered was the failure of the number 5 cylinder connecting rod. The eng was reportedly recently overhauled but the logbooks were inside the acft & were not recovered.
