## Discrepancy

DURING CRUISE FLIGHT AT 27,000 FT, HAD A PRESSURE POP AND THEN A CABIN ALT WITH TRIPLE CHIME.  PERFORMED PRECAUTIONARY EMERGENCY DESCENT TO 10,000 FT AT THAT POINT, WENT TO QRH.  FOLLOWED PROCEDURE FOR LOSS OF CABIN PRESSURE.  WENT TO MANUAL MODE ON PRESSURIZATION CONTROL AND WAS ABLE TO CONTROL CABIN.  CONTINUED TO SLC AND LANDED WITHOUT INCIDENT.  REPLACED AUTO-MAN DAMP SWITCH.  OPS CHECK GOOD IAW 20-13-03 AND 21-30-00.
