## Discrepancy

DURING GROUND RUN, THE PILOT OBSERVED THE NR 1 ENGINE OIL TEMP WAS ELEVATED.  UPON ARRIVING BACK TO DEPARTURE, IT WAS FOUND THAT THE LT OIL COOLER BLOWER WAS NOT TURNING WHILE ROTATING THE MGB.  MECHANIC CONFIRMED DISCREPENCY.  NO METAL FOUND IN MGB OIL FILTER AND ONLY VERY SMALL FUZZ FOUND ON MGB CHIP PLUG.  DUE TO THIS BEING THE THIRD OIL COOLER BLOWER SHAFT SHEER IN A 6 WEEK TIME LINE THE MFG WAS CONSULTED.   MGB CHANGE IS IN PROGRESS.
