## Discrepancy

DURING AN OPERATIONAL CHECK OF THE INFLATABLE EVACUATION SYSTEM AT THE RT UPPER DECK DOOR ACCORDING MS 23-66-00-040-100 THE RESERVOIR WAS NOT ACTIVATED AND THE SLIDE DID NOT INFLATE.  FURTHER INVESTIGATION REVEALED THAT THE PACKBOARD LOCKING PLATE WAS RELEASED DUE TO A BENT MECHANISM.  THEREFORE, THE LOCKING PLATE SLIPPED OVER THE LOCKLEVER AND WAS NOT ABLE TO FULLFIL THE ORIGINAL FUNCTION.  CHANGED BENT LOCKING PLATE.
