Airworthiness Directive · Amendment 39-19839 · Oxygen
Airbus SAS Airplanes
Superseded. A later AD replaced this one: AD 2025-11-12. Comply with the one in force.
This AD applies to all Airbus SAS Model A350-941 and -1041 airplanes, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A350-941 and -1041 airplanes. This AD was prompted by reports of loss of retention of the regulator inlet filter retainer on certain crew oxygen cylinder assemblies. This AD requires an inspection of the crew oxygen cylinder assembly for any discrepancy and replacement of an affected crew oxygen cylinder assembly with a serviceable part, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
Except as specified in paragraph (h) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, European Union Aviation Safety Agency (EASA) AD 2019-0168, dated July 16, 2019 (“EASA AD 2019-0168”).
(1) Where EASA AD 2019-0168 refers to its effective date this AD requires using the effective date of this AD.
(2) The “Remarks” section of EASA AD 2019-0168 does not apply to this AD.
(3) Where paragraphs (1) and (2) of EASA AD 2019-0168 state “the instructions of the AOT,” replace that language with “paragraph 4.2.2., Inspection Requirements, of the AOT.”
(4) Where paragraph (1) of EASA AD 2019-0168 specifies to “inspect each affected part,” this AD requires a one-time inspection of any “affected part” that is installed on-wing.
Although the service information referenced in EASA AD 2019-0168 specifies to submit certain information to the manufacturer, this AD does not include that requirement.
Although the service information referenced in EASA AD 2019-0168 specifies to return affected parts to the manufacturer, this AD does not include that requirement.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
