## Discrepancy

DURING A FLIGHT JUST AFTER TAKEOFF, PILOT REPORTED THE ENGINE PERIODICALLY LOST POWER AND VIBRATED.  UPON LANDING, PILOT ALSO NOTICED A CONSIDERABLE AMOUNT OF OIL ON THE NACELLE.  UPON INVESTIGATION, DISCOVERED THE NR 6 CYLINDER PUSH ROD WAS BENT AND PUSH ROD TUBE HAD BROKEN.  AFTER CYLINDER REMOVAL, IT WAS DETERMINED A SCREW HAD BEEN INJESTED INTO THIS CYLINDER.  GOOD HOUSEKEEPING PROCEDURES AND ACCOUNTABILITY OF HARDWARE DURING INSTALLATION WOULD REDUCE THE POSSIBILITY OF THIS IN THE FUTURE.
