Required actions

If any affected oxygen cylinder and regulator assembly (OCRA) is installed, before further flight replace the affected part with a new or reworked OCRA, in accordance with the Accomplishment Instructions of SB 700-35-7502.
Unsafe condition
This AD was prompted by a report that the flightcrew and passenger oxygen system's refill and capillary lines may have been contaminated by sealant and cotton fibers. The FAA is issuing this AD to address the contamination, which may cause a blockage of the oxygen system components and result in a reduction of oxygen flow, reduce the total amount of available oxygen, or create a fire hazard.
Affected ADs
None.
