## Discrepancy

SMOKE CAME OUT OF OVERHEAD VENT AT REAR OF COCKPIT FOR APPROX 5 SECONDS.  JUST TURNED UP COCKPIT & COURIER TEMPS FROM 67 TO 74 DEGREES.  DONNED O2 MASKS & TURNED DOWN BOTH TEMPS TO 70 DEGREES.  FIRST SMELLED SOMETHING HOT & THAT PROMPTED US  TO TURN AROUND.  THE SMOKE NEVER CAME FWD TO OUR  SEATS & IT WENT AWAY AFTER APPROX 10 SECONDS.  RAN NR 1 & 3 PACKS FOR 20 MINUTES & DID NOT NOTICE ANY ODOR OR SMOKE.  ALL TEMPS WERE IN LIMITS & CHANGED NR 1 & 3 COALESCER BAGS IAW MM 21-54-03-2.  OK FOR  SERVICE.
