Narrative:
At FL280, cabin pressure was climbing at 1000 FPM. Declared an emergency and initiated descent as cabin reached 10000 ft. Accomplished appropriate checklist. Regained control of cabin at 12000 ft. System worked normally for remainder of flight to msp. Suspect icing up of outflow valve due to icing conditions we were in the last 45 mins before the pressurization problem.

Title: EMER DECLARED WITH ASSOCIATED DSCNT WHEN LOSS OF CABIN PRESSURE EXPERIENCED BY ACR MLG.
Narrative: AT FL280, CABIN PRESSURE WAS CLBING AT 1000 FPM. DECLARED AN EMER AND INITIATED DSCNT AS CABIN REACHED 10000 FT. ACCOMPLISHED APPROPRIATE CHKLIST. REGAINED CTL OF CABIN AT 12000 FT. SYS WORKED NORMALLY FOR REMAINDER OF FLT TO MSP. SUSPECT ICING UP OF OUTFLOW VALVE DUE TO ICING CONDITIONS WE WERE IN THE LAST 45 MINS BEFORE THE PRESSURIZATION PROB.
