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 manufacturer 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.
