## Discrepancy

(CAN) DURING FLIGHT, THE PILOT SAW THAT THE NR 1 ENGINE OIL TEMP REACHED 119 DEGREES C FOR 2 MINUTES AND THAT THE CB1, CB17 POPPED OUT.  IT`S ALWAYS HAPPENED WHEN THE HELICO IS IN STATIONNARY FLIGHT POSITION FOR A LONG PERIOD AND THE OUTSIDE TEMP IS HIGH,  ABOVE 23 DEGREES C.  IT`S NEVER HAPPENED IN CRUISE.
