The airplane was substantially damaged at about 1325 Eastern time during a forced landing following a total loss of engine power. The flight instructor (CFI) and commercial-rated student pilot were not injured. Visual conditions prevailed.
According to the CFI, upon reaching 3000 feet MSL, the engine began to run rough and several loud noises were heard. The engine then lost all power, with zero oil pressure and rpm. Oil was visible on the windscreen. After securing the engine, the CFI set up for a forced landing in a nearby field. After an uneventful landing, the landing gear contacted a ditch and nosed over. A cursory examination revealed the engine case was ruptured and the camshaft was partially exposed.
