## Discrepancy

DEN - FLT 401 - AIR TURN BACK.  FLIGHT CREW REPORTED AIRCRAFT WOULD NOT PRESSURIZE.  MAINTENANCE PLACARDED THE RIGHT PACK HIGH FLOW MODE PER MEL 21-2-1.  SUPPLEMENTAL INFORMATION WILL BE SUBMITTED WHEN IT IS AVAILABLE.  THIS MRR IS A SUPPLEMENT TO CLOSE MRR NR F3LA-97-099.  ON 4-6-97, MAINTENANCE REPLACED THE RIGHT FLOW CONTROL VALVE AND SYSTEM CHECKED OKAY.  (X)
