Read the full NTSB narrative

THE PILOT EXPERIENCED AN ENGINE FAILURE AND EXECUTED AN EMERGENCY LANDING ON A NARROW ROAD WHICH RESULTED IN ONE OF THE LANDING GEAR TOUCHING DOWN ON THE SOFT SHOULDER. THE LANDING GEAR FAILED AND SUBSTANTIAL DAMAGE RESULTED. EXAMINATION OF THE ENGINE REVEALED THAT THE CYLINDER SEPERATED DUE TO IMPROPERLY TORQUED STUD BOLTS WHICH ALLOWED AN OVER STRESS CONDITION TO EXIST ON A FEW STUDS THAT WERE PROPERLY TORQUED.
