## Discrepancy

ACFT WOULD NOT MAKE MAX DIF IN FLIGHT, AND THE PASSENGER SAID THAT THEY COULD HEAR ALOT MORE WIND NOISE AROUND THE CABIN DOOR AREA THAN NORMAL.  GROUND CHECKED THE SYS AND FOUND THAT THE CABIN DOOR PNEUMATIC VALVE WAS STUCK IN THE CLOSED POSITION.  THIS VALVE IS IN A LOW AREA OF THE BLEED AIR SYS AND IS PRONE TO WATER GETTING INTO THE VALVE AND CORRODING IT.  THIS VALVE NEEDS TO BE REMOVED AT SOME INSP TIME INTERVAL AND CLEANED THIS WOULD KEEP THIS FROM HAPPENING.
