## Discrepancy

LOST CABIN PRESSURE ON DESCENT AT 7000 FEET. COULD NOT PRESSURIZE EVEN IN MANUAL. FLIGHT ATTENDANT NOTICED HISSING NOISE AT AFT AIR STAIRS DOOR. MANTENANCE INSPECTED ALL DOOR SEALS; CYCLED THE PASSENGER AND CARGO DOOR HANDLES; CLEANED AROUND THE AFT PASSENDER DOOR SEAL. MAINTENANCE PERFORMED AN OPERATIONAL CHECKS WITH ENGINES RUNNING. ALL CHECKS WERE GOOD. THE AIRCRAFT RETURNED TO SERVICE.
