## Discrepancy

THE AIRCRAFT HAD A BRIEF HISTORY OF SMOKE APPEARING IN THE COCKPIT AND CABIN MOMENTARILY WHILE IN FLIGHT.  THE SMOKE DISSIPATED QUICKLY ONCE THE EFFECTED PACK WAS TURNED OFF.  THE APU WAS REMOVED AND REPLACED IAW MM 49-00-00, PAGES 401-415.  OPERATIONAL CHECKS WERE GOOD WITH NO SMOKE DETECTED.
