## Discrepancy

ON CLIMB OUT ON A MEDIVAC FLIGHT (FLIGHT PLANNED ROUTE FOR FL 140), THE PRESSURIZATION FAILED AT 70 AST.  PILOT REQUESTED FL 100 (NEW FLIGHT PLANNED ROUTE) AND THE FLIGHT CONTINUED WITHOUT INCIDENT.  EXTERNAL FILTER ON THE CONTROLLER WAS FOUND TO BE PLUGGED.  FILTER WAS CLEANED AND NO FURTHER INCIDENTS HAVE PREVAILED.
