Read the full NTSB narrative

During the cross-country flight, the engine experienced a total loss of power and the student pilot performed a forced landing to a field. The airplane nosed over during the landing and came to rest inverted. An examination of the engine revealed that the incorrect bearing and thrust washer had been used during the engine reassembly about 90 flight hours before the accident, resulting in the seizure and failure of the #1 and #2 connecting rods and the subsequent loss of engine power. The mechanic who performed the overhaul and reassembly used an outdated parts manual and installed the improper bearing and thrust washer assembly.
