C

. REASON

During m anufacturing at the manufacturer facilities particles had been detected in the oxygen generator manifolds. Investigation revealed that those pa rticles (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 ch ips . Such ch ips may reduce or block the oxygen supply . Green Dot

### For 1XC15

- 0100 Series Oxygen Container

This Service Bulletin may be accomplished on the Aircraft or in the work shop

. Th e estimated time to do the work in this Service Bulletin is 0. 3 0 hours per oxygen container

. (1) O pen the door of the oxygen container.

(2) Remove and secure the mask assemblies with rubber bands against uncoiling ( preferable by a second person) . Disconnect the mask lanyards (remain attached to the release pin) at the mask assemblies

. (3) Remove th e manifold together with mask hoses from the oxygen generator , c ut the mask hoses from the manifold fitting s . Discard the manifold.

(4) Install the mask hoses to the fittings of a new manifold
, install the manifold back to the oxygen generator

. (5) Connect the mask lanyards to the mask assemblies

. Repack the oxygen mask assemblies and close the door assy.

(6) Do a manual door release test with test button in test position



### For 1XC22

- 0100

- Series Oxygen Container

This Service Bulletin is recommended to be performed in a workshop within the following approximate man

- hours and elapsed time of 0.5 hours per oxygen container

.
NOTE : The man

- hours and elapsed time do not include the removal/installation of the

oxygen container from/to the aircraft.

(7) Open the door of the oxygen container, secure the mask assemblies with a rubber band
, remove the oxygen generator together with the mask assemblies

. Disconnect the mask lanyards (remain attached to the release pin) at the mask assemblies

(8) Remove the manifold together with mask hoses from the ox ygen generator, cut the mask hoses from the manifold fittings. Discard the manifold.

(1) Remove the oxygen container from the aircraft as specified in the Aircraft Maintenance Manual.

(2) Put the oxygen container on a clean flat surface so that the door assy shows face up and the test button is in front of you.

(3) Open the Door Assy as follows:

CAUTION : EXERCISE CAUTION WIT H THE MASK LANYARDS WH EN YOU OPEN
