## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

DURING CRUISE FLIGHT ON 11/08/2010 ENGINE BEGAN TO RUN ROUGH. PILOT MADE A PRECAUTIONARY LANDING AT CARROLL COUNTY AIRPORT (DMW). MECHANIC FOUND #1 CYLINDER WITH A STUCK INTAKE VALVE, ONE SEVERELY BENT INTAKE PUSHROD, A BOWED EXHAUST PUSHROD, A DAMAGED ROCKER ARM ON THE INTAKE SIDE. IT WAS ALSO DISCOVERED THAT THE ROCKER ARMS FOR THE # 1 AND 3 CYLINDERS WERE INSTALLED IN THE WRONG POSITIONS. THE INTAKE WAS ON THE EXHAUST SIDE AND THE EXHAUST ON THE INTAKE SIDE. THIS WAS VERIFIED BY THE PART NUMBERS THAT ARE VIBRO-ETCHED INTO THE PARTS. THIS INRRECT INSTALLATION CAUSED THE ROCKER ARMS TO CUT A GROOVE INTO THE RUSHRODS ON CYLINDERS 1 & 3. THIS CUTTING PUT METAL THROUGHOUT THE ENGINE. THE OIL FILTER WAS CUT OPEN AND METAL WAS FOUND IN MOST ALL OF THE PLEETS OF THE FILTER PAPER. METAL WAS ALSO FOUND IN THE LOWER OIL SCREEN. THE AMOUNT OF DAMAGE TO THE PUSHRODS IN ONLY 7 HOURS WOULD LIKELY HAVE CAUSED A TOTAL ENGINE FAILURE IN A SHORT PERIOD OF TIME IF THIS ENGINE CONTINUED TO OPERATE.
