What to do
Operators of affected Airbus A330 and A340 aircraft must replace the halon outlet tubes in the LDMCR fire extinguisher assemblies with the specified flexible hoses within six months from 2020-11-27. Additionally, from the effective date, no affected assembly may be installed on any aircraft. Maintenance teams should follow Zodiac Galleys Europe Service Bulletin 663075-25-001 for replacement instructions and coordinate with EASA for any alternative compliance methods if needed.
Summary
EASA Airworthiness Directive 2020-0255 is an airworthiness directive issued by the European Union Aviation Safety Agency affecting Airbus A330 and A340 aeroplanes equipped with a lower deck mobile crew rest (LDMCR) fire extinguisher assembly. The directive addresses a potential issue with the halon outlet tube connection on certain fire extinguisher bottles installed in these aircraft models. It mandates replacement of the affected halon outlet tubes to ensure proper fire suppression functionality.
What changed
EASA Airworthiness Directive 2020-0255 introduces a new mandatory replacement requirement for the halon outlet tubes (P/N 663075-11) installed in the LDMCR fire extinguisher assemblies on specific Airbus A330 and A340 aircraft. The directive requires operators to replace these tubes with flexible hoses (P/N 241502-3) within six months of the effective date. It also prohibits installation of affected assemblies on any aircraft from the effective date onward.
Why it matters
This directive is critical for aviation professionals because an incorrect connection of the halon outlet tube could lead to disconnection during a fire event, reducing the effectiveness of the fire suppression system in the LDMCR. Compliance ensures continued airworthiness and safety by maintaining proper fire protection in crew rest areas. Operators, maintenance organizations, and compliance teams must address this to avoid operational restrictions and ensure regulatory compliance.
