What was found
OXYGEN LINE WAS PERFORATED BY AN UPHOLSTERY TRIM SCRE. DURING THE PROCESS OF A ROUTINE ANNUAL INSPECTION, THE LEFT SIDE TRIM PANES WAS REMOVED AND THE HOLE WAS DISCOVERED. THE LINE SHOULD HAVE BEEN RUN LOWER AND TIED TO A GLUED ON SKIN ATTACH POINT, BUT WAS NOT, PRESUMABLE FROM THE FACTORY SINCE THIS PANEL HAD MOST LIKELY NOT PREVIOUSLY BEEN REMOVED.
