## Discrepancy

EACH SHIFT HAS NOW FOUND MORE FINDINGS WHICH ARE RELATIVELY CRITICAL FINDINGS SUCH AS LIQUID IN SOME OXYGEN MASKS AND OXYGEN TUBING IN THE CABIN COMPARTMENT HANGING FREELY WITHOUT BEING SECURED. A SERVICEABLE TAG FROM THE COMPANY VALLAIR HAS ALSO BEEN FOUND.  A SAMPLE OF THE LIQUID FOUND WILL BE SUBMITTED FOR ANALYSIS TO DETERMINE ITS COMPOSITION.  INCLUDING THE ASSESSMENT OF ECCAIRS REPORTABILITY, WILL BE DETERMINED.  THE SAMPLE WAS SEND TO ANALYSIS WITH THE LABORATOY OF LUFTHANSA TECHNIK THE 19-10-2026, THE CONTAMINATION (LIQUID) FOUND IN THE OXY MASK TUBS ARE PROBABLY BASED ON A CHEMICAL BINDER PRODUCT (BASED ON RESIN-MODIFIED, SHORT-OIL ALKYD). THE EXACT SOURCE OF THE CONTAMINATION COULD NOT BE IDENTIFIED.  ECCAIRS REPORT NUMBER: OR-0000000001749331
