## Analysis

DURING A PLEASURE CROSS COUNTRY FLT, A PRECAUTIONARY LANDING WAS MADE DUE TO SMOKE IN THE COCKPIT AND A LOW OIL PRESSURE INDICATION. AFTER LANDING, IT WAS FOUND THAT THE OIL LINE TO THE OIL PRESSURE GAUGE WAS BROKEN. AFTER REPAIRS, THE PLT TOOK OFF AND 10 MINUTES INTO THE FLT THE ENGINE EXPERIENCED AN OVERSPEED. A FEW MINUTES LATER, THE PLT HEARD A LOUD BANG AND OIL BEGAN TO COVER THE WINDSHIELD. THE PLT MADE AN EMERGENCY LANDING ON A ROAD. DURING THE LANDING ROLL, THE AIRCRAFT COLLIDED WITH A POLE. INSPECTION OF THE ENGINE REVEALED THAT THE NO. 4 CONNECTING ROD HAD FAILED AND PUNCTURED THE CRANKCASE. FURTHER EXAMINATION REVEALED THAT THE BEARING SHOWED EVIDENCE OF HIGH TEMP SCORCHING.
