## Discrepancy

PAX O2 MASKS DROPPED DURING DEPRESSURIZATION.  MASKS IN ROW 3 DID NOT DROP.  CREW MASKS WERE DEPLOYED.  CLEANED THE USED MASKS AND RE-PACKED AND STOWED.  ROW 3 PAX O3 MASK DOOR INTERFERES WITH ADJACENT ACCESS PANEL.  TRIMMED EDGE OF ACCESS PANEL AS NEEDED TO PROVIDE CLEARANCE FOR O2 MASK DOOR.  OPERATIONAL CHECK GOOD.
