What was found
DURING FLIGHT, AT FL360 THE RH PACK WENT INOP. AS OUR LIMITATION STATES 1 PACK OPERATION MUST BE FL310 OR BELOW, THE CREW REQUESTED THE DESCEND TO COMPLY. ATC COULD NOT PROVIDE THIS, SO THE CREW DECLARED. AFTER DESCENDING, AND CONTINUING ON, THE PACK RESUMED FUNCTIONING AT WHICH POINT THE FLIGHT CREW CANCELLED THE EMERGENCY AND LANDED SAFELY AND NORMALLY IN BHM WITH NO OTHER ISSUES. NO OTHER MAINTENANCE WAS PERFORMED.
