## Discrepancy

(CAN) NR 2 ENGINE MOT WENT TO A MAX TEMP OF 127.8 C, AREA B FOR 666 SECONDS AND AREA D FOR 261 SECONDS IAW MM.  THE CAPTAIN REDUCED THE TORQUE DOWN TO 68 PERCENT WHEN OIL TEMP WENT ABOVE 100 C.  THE ENGINE WAS SHUTDOWN IN FLIGHT AT A MOT INDICATION OF 126C. SUSPECT A DEFECTIVE OIL COOLER, BUT TROUBLESHOOTING IS ONGOING.
