## Discrepancy

BROKEN PRV FOUND IN SLIDE WHEN OPENED FOR OVERHAUL.  SLIDE WOULD NOT HOLD AIR PRESSURE.  DAMAGED PRESSURE RELIEF VALVE WAS OBSERVED DURING SLIDE/RAFT COMPONENT SHOP MAINTENANCE. THE EXACT CAUSE OF THE DAMAGE TO THE PRESSURE RELIEF VALVE COULD NOT BE DETERMINED, BUT IT IS SPECULATED IT WAS DAMAGED DURING THE LAST PACKING PROCESS. PRESSURE RELIEF VALVE ASSEMBLY WAS REPLACED.
