Narrative:

Engine's 6TH cylinder rod broke in half. Engine indicated drop in manifold pressure approximately 4 inches. An aircraft nearby said smoke was trailing behind. Diverted to closest major airport but engine failed prior to reaching it. Turned to second choice airport for landing. Propeller still wind milling. I shut down the engine and when the magnetos were turned to the 'off' position; the engine ceased; propeller stopped; and oil covered the windscreen. Landing was assured; and we glided in with no problem; nor any further damage to the airframe. If oil pressure drops off; you can plan on an engine to fail shortly afterwards. So if you can land with some power; better than none at all.

Title: A PA32 DIVERTED AND LANDED IN EMER CONDITION DUE TO ENG FAILURE CAUSED BY #6 CYLINDER CONNECTING ROD FAILURE. INFLT ENG SHUTDOWN.

Narrative: ENGINE'S 6TH CYLINDER ROD BROKE IN HALF. ENG INDICATED DROP IN MANIFOLD PRESSURE APPROX 4 INCHES. AN ACFT NEARBY SAID SMOKE WAS TRAILING BEHIND. DIVERTED TO CLOSEST MAJOR ARPT BUT ENG FAILED PRIOR TO REACHING IT. TURNED TO SECOND CHOICE ARPT FOR LNDG. PROP STILL WIND MILLING. I SHUT DOWN THE ENG AND WHEN THE MAGNETOS WERE TURNED TO THE 'OFF' POS; THE ENG CEASED; PROP STOPPED; AND OIL COVERED THE WINDSCREEN. LNDG WAS ASSURED; AND WE GLIDED IN WITH NO PROB; NOR ANY FURTHER DAMAGE TO THE AIRFRAME. IF OIL PRESSURE DROPS OFF; YOU CAN PLAN ON AN ENG TO FAIL SHORTLY AFTERWARDS. SO IF YOU CAN LAND WITH SOME PWR; BETTER THAN NONE AT ALL.
