A B747-200 WAS DISPATCHED IN NON COMPLIANCE WITH LIGHT CORROSION ON A PAX OXYGEN MANIFOLD NOT TREATED OR DEFERRED FOR LATER ACTION.

Narrative

ON JUL/FRI/00; WORKING ON ACFT XYZ; CLEANING DINOL (CORROSION PREVENTIVE FLUID) FROM PAX OXYGEN LINES; NOTICED A DISCOLORATION ON THE OXYGEN MANIFOLD LINES IN THE OVERHEAD PSU'S. I NOTIFIED MY LEAD; MGR; ENGINEERING AND ANOTHER MECH ABOUT WHAT I FOUND. BY XA00 PM; JUL/FRI/00; NO DECISION WAS MADE AS TO WHAT AND IF IT WAS DISCOLORATION; CORROSION OR SOMETHING ELSE. THE MATTER WAS TURNED OVER TO MGMNT AND ENGINEERING. I RETURNED BACK TO WORK ON JUL/MON/00. I WAS HANDED OXYGEN JOB CARD AND A BOEING RPT ON HOW TO REMOVE CORROSION FROM OXYGEN LINES. I INFORMED MGMNT THAT IF THIS SURFACE CORROSION WAS TO BE REMOVED USING THE BOEING GUIDELINES THAT THE MANIFOLD MIGHT BE TAKEN OUT OF REPAIR LIMITS. MGMNT TOOK THE JOB CARD AND TOLD ME THEY WOULD TAKE CARE OF THE MATTER. THAT WAS THE LAST I HEARD ABOUT IT. ON AUG/TUE/00; I HAD A DEATH IN THE FAMILY AND DID NOT RETURN BACK TO WORK UNTIL AUG/FRI/00. I WAS LATER INFORMED AFTER COMING BACK THAT THE ACFT WAS RELEASED FOR FLT AND THE LIGHT SURFACE CORROSION WAS NEVER ADDRESSED.
