Narrative:

At 19000', the left engine suddenly went from 31' of manifold pressure to 25' and began running slightly rough. I reduced power to 21' mp and noticed quite a bit of oil coming out of the engine. I informed center of the problem, and after about another 10 mins decided to feather the propeller. Normal shutdown procedures were followed, after I obtained a clearance to 11000'. I advanced the right engine to 75% power and gradually drifted down at 100 FPM and elected to land in wichita. I did not declare an emergency, as the situation was well in hand. The approach and landing were completed normally with excellent cooperation from center and wichita approach control. Wichita tower called for emergency vehicles, even though they were not requested. After landing, I cleared the active runway and coasted to a stop about 200' down the taxiway, where shutdown was completed and we were towed to the local FBO. The engine had lost 1 qt of oil and registered 11 qts qty on the dipstick. Cause of the partial power loss was a cracked cylinder (#5). I informed a local FAA maintenance inspector of this and he is looking into the matter.

Title: TWIN ENGINE SMT EXPERIENCES POWER LOSS IN CRUISE AND SHUTS DOWN #1 ENGINE AFTER OIL LOSS NOTED, AND 10 MINUTES OF TIME FOR CONSIDERATION. DIVERTS TO LAND AT ICT. TWR ACTIVATES EMERGENCY EQUIPMENT ON OWN VOLITION.

Narrative: AT 19000', THE LEFT ENG SUDDENLY WENT FROM 31' OF MANIFOLD PRESSURE TO 25' AND BEGAN RUNNING SLIGHTLY ROUGH. I REDUCED PWR TO 21' MP AND NOTICED QUITE A BIT OF OIL COMING OUT OF THE ENG. I INFORMED CENTER OF THE PROB, AND AFTER ABOUT ANOTHER 10 MINS DECIDED TO FEATHER THE PROP. NORMAL SHUTDOWN PROCS WERE FOLLOWED, AFTER I OBTAINED A CLRNC TO 11000'. I ADVANCED THE RIGHT ENG TO 75% PWR AND GRADUALLY DRIFTED DOWN AT 100 FPM AND ELECTED TO LAND IN WICHITA. I DID NOT DECLARE AN EMER, AS THE SITUATION WAS WELL IN HAND. THE APCH AND LNDG WERE COMPLETED NORMALLY WITH EXCELLENT COOPERATION FROM CENTER AND WICHITA APCH CTL. WICHITA TWR CALLED FOR EMER VEHICLES, EVEN THOUGH THEY WERE NOT REQUESTED. AFTER LNDG, I CLRED THE ACTIVE RWY AND COASTED TO A STOP ABOUT 200' DOWN THE TXWY, WHERE SHUTDOWN WAS COMPLETED AND WE WERE TOWED TO THE LCL FBO. THE ENG HAD LOST 1 QT OF OIL AND REGISTERED 11 QTS QTY ON THE DIPSTICK. CAUSE OF THE PARTIAL PWR LOSS WAS A CRACKED CYLINDER (#5). I INFORMED A LCL FAA MAINT INSPECTOR OF THIS AND HE IS LOOKING INTO THE MATTER.
