## Discrepancy

AFTER TAKEOFF, LEFT ENGINE STARTED VIBRATING.  ENGINE WAS SHUT DOWN AND AIRCRAFT RETURNED TO THE AIRPORT.  INSPECTION REVEALED A CRACK IN THE NR 5 CYLINDER.  SINCE OVERHAULED CYLINDERS HAVE HIGH TOTAL TIME, THEY ARE MORE LIKELY TO CRACK DUE TO AGE AND STRESS.  RECOMMEND USING NEW CYLINDERS AT OVERHAUL TO REDUCE RECURRENCE OF THIS PROBLEM.
