What to do
Operators of Airbus A350-941 and A350-1041 aeroplanes must inspect and replace passenger oxygen masks containing affected parts before the aircraft reaches 72 months since its date of manufacture. Affected parts must not be installed on any aircraft after replacement or from the effective date for aircraft without affected parts. Compliance must follow the instructions in Airbus Service Bulletin A350-35-P013.
Summary
EASA Airworthiness Directive 2020-0031 is an airworthiness directive issued by the European Union Aviation Safety Agency affecting Airbus A350-941 and A350-1041 aeroplanes. It addresses an unsafe condition related to passenger oxygen masks that may stick and fail to fully inflate after exposure to high ground temperatures. The directive mandates replacement of affected passenger oxygen masks to ensure continued airworthiness.
What changed
EASA Airworthiness Directive 2020-0031 introduces a requirement to identify and replace passenger oxygen masks containing specific affected parts and serial numbers on Airbus A350 aircraft. It prohibits the re-installation of these affected parts after replacement. This directive is a new regulation addressing a safety issue with oxygen masks manufactured from a specific raw material lot.
Why it matters
This directive is critical for aviation professionals because it prevents potential failure of passenger oxygen masks during depressurization events, which could result in injury to cabin occupants. Operators and maintenance organizations must ensure compliance to maintain aircraft airworthiness and passenger safety. Non-compliance could lead to regulatory penalties and increased safety risks.
