Analysis

While on a dual student plt flt, about 10 minutes after takeoff, the eng began severely vibrating. The instructor plt took control of the acft, reduced power and established a glide to a local arpt. The engine then suddenly failed completely. The instructor plt then executed a forced landing into trees. Subsequent examination of the engine revealed that the #2 cylinder connecting rod had failed and penetrated the engine case. The crankshaft journal for the #2 cylinder was heat damaged and the rod cap bearing could not be found. The other cylinder bearings were scored and extensively worn. Available records indicate that the engine had been overhauled about 832 hours previously.
