EASA AD 2019-0183
Electric and Electronic Common Installation — Cargo Lining Gutter Assemblies — Modification
Summary
EASA Airworthiness Directive 2019-0183 is an airworthiness directive issued by the European Union Aviation Safety Agency affecting Airbus A350-941 aeroplanes. It mandates a modification to the electric and electronic common installation, specifically the cargo lining gutter assemblies, to improve water drainage and prevent potential water spillage risks. This directive applies to all Airbus A350-941 aircraft except those with Airbus modification 111827 incorporated in production.
What Changed
This new airworthiness directive introduces a required modification to the cargo lining gutter assemblies by implementing a new drain gutter design with improved outlets on both sides. The change addresses the risk of water overflow caused by leakage or rupture of potable water distribution pipes near the electronics bay entrance. The modification is detailed in Airbus Service Bulletin A350-92-P014.
Why It Matters
This directive is critical for aviation professionals because it mitigates the risk of fluid contamination of electrical equipment and connectors, which could lead to loss of multiple flight control functions and reduced aircraft control. Operators and maintenance teams must ensure compliance to maintain aircraft safety and airworthiness. Failure to comply could result in unsafe flight conditions and regulatory non-compliance.
What To Do
Operators of affected Airbus A350-941 aeroplanes must modify the cargo lining gutter assemblies according to Airbus Service Bulletin A350-92-P014 before the aircraft reaches 80 months since its date of manufacture. Maintenance and compliance teams should plan and execute this modification within the specified timeframe to ensure continued airworthiness and regulatory compliance.
