NOTE : As far as still available at the Airbus final assembly line a few aircraft have already been reworked before handover to the operator .Those units have been marked with a green dot on the test button label as shown below and do not need further rework.

B. CONCURRENT REQUIREMENTS

Not Applicable

C. REASON

During manufacturing at the ma nufacturer facility particles had been detected in the oxygen generator manifolds. Investigation revealed that those particles (chips) are chafed from the mask hoses when installed onto the generator outlets. It was found out that a defective mask hose installation device has caused the chips. Such chips may reduce or block the oxygen supply.

A replacement of the manifold is necessary. Green Dot
