## Discrepancy

AFTER TAKEOFF, A "VENT BLOWING FAULT" WAS DETECTED, AND THE AIRCRAFT EXPERIENCED A CABIN PRESSURIZATION ISSUE. THE CREW DECIDED TO MAINTAIN ALTITUDE, DURING WHICH THE PRESSURIZATION WAS RESTORED, THEN THE FLIGHT PROCEEDED TO MAO STATION. UPON LANDING, MAINTENANCE INSPECTIONS WERE CARRIED OUT IN ACCORDANCE WITH THE MANUALS (AIRBUS TSM TASK 21-26-00-810-804-A & TSM TASK 21-51-00-810-848-A). NO DISCREPANCIES WERE FOUND, AND THE ASSOCIATED PRESSURIZATION SYSTEMS WERE CONFIRMED TO BE OPERATING NORMALLY.
