## Discrepancy

DURING A SCHEDULED TEST FLIGHT, WHILE IN CRUISE THE SMOKE DETECTOR SOUNDED WITH SMOKE OCCURRING IN THE CABIN.  THE PACK SUBSEQUENTLY FAILED AND THE SMOKE DISSIPATED.  QRH PROCEDURES WERE COMPLIED WITH AND THE AIRCRAFT LANDED SAFELY.  MAINTENANCE RAN THE AUXILIARY POWER UNIT, PERFORMED ENGINE GROUND RUNS AND INSPECTED THE PACKS.  NO DEFECTS WERE NOTED.  AIRCRAFT OK FOR SERVICE.  (M)
