What to do
Operators of Airbus A350-941 and A350-1041 aeroplanes must identify if affected emergency passenger oxygen container assemblies are installed and replace the passenger oxygen masks within the compliance times specified, which is before 72 months since the aeroplane's date of manufacture or within 6 months after the AD's effective date if the relevant service bulletin has not been embodied. Additionally, installation of affected parts is prohibited after replacement or from the effective date for aeroplanes without affected parts.
Summary
EASA Airworthiness Directive 2022-0112 is an airworthiness directive affecting Airbus A350-941 and A350-1041 aeroplanes. It addresses an unsafe condition related to passenger oxygen masks, specifically the emergency passenger oxygen container assemblies that may have breathing bags prone to sticking after exposure to high temperatures. The directive mandates replacement and re-identification of affected passenger oxygen masks to ensure safety during depressurization events.
What changed
EASA Airworthiness Directive 2022-0112 supersedes the previous AD 2020-0031 and expands the list of affected emergency passenger oxygen container assemblies by including additional serial numbers identified by B/E Aerospace. It retains the original replacement requirements but adds further affected parts and updates the related Airbus Service Bulletin to Revision 02.
Why it matters
This directive is critical for aviation professionals because it addresses a potential safety hazard where passenger oxygen masks may fail to inflate properly during an emergency, risking injury to cabin occupants. Operators and maintenance organizations must ensure compliance to maintain airworthiness and passenger safety. Failure to comply could result in regulatory penalties and increased operational risk.
