## Discrepancy

(CAN) THE RT ENG WOULD NOT START, SO IT WAS SENT TO MX WHERE THEY DISCOVERED ON THE NR 4 CYLINDER, THE EXHAUST VLVS WERE STUCK OPEN & THE PISTON WAS SCORED.  THE CYLINDER HEAD WAS REMOVED AS WELL AS THE PISTON.  DISCOVERED THAT THE RINGS HAD LOST THEIR TEMPER, BUT THE PISTON & HEAD WERE OK.  THIS IS AN ENG THAT WAS REPLACED DUE TO FAILURE IN AUGUST 2014 & HAD ONLY 197 HOURS ON IT.  THE ACFT HAS 933.6 HOURS ON THE AIRFRAME.
