## Discrepancy

ON TAKE OFF JUST AFTER ROTATION R ENG OIL TEMP WENT YELLOW @ 105* C. THEN 109* C. DURING THE COURSE CHANGE TURN THE R ENG OIL TEMP TURNED RED @ 117*C.

GROUND OPERATIONAL CHECKS PERFORMED WITH NO DEFECTS NOTED. A SUCCESSFUL OPERATIONAL CHECK WAS PERFORMED. AIRCRAFT WAS RETURNED TO SERVICE.
