EASA AD 26-118
Fire Protection – Fire-extinguishing Pipes – Replacement
Summary
EASA Airworthiness Directive Proposal 26-118 addresses a safety issue on Airbus A380-861 aeroplanes equipped with EA GP7200 engines. It concerns the replacement of fire-extinguishing pipes, specifically part number L2621011100200, located in the core zone of each engine pylon. The directive aims to improve fire protection by mandating the installation of redesigned fire-extinguishing pipes.
What Changed
This proposed Airworthiness Directive introduces a requirement to replace the affected fire-extinguishing pipes with a redesigned part, P/N L2621090000000, to mitigate cracking caused by excessive vibrations. It also prohibits the reinstallation of the affected parts after replacement. This is a new regulation addressing a specific unsafe condition identified in the Airbus A380-861 engine pylons.
Why It Matters
This directive is critical for maintaining the effectiveness of the engine fire extinguishing system on affected Airbus A380 aircraft. Cracks in the fire-extinguishing pipes could compromise fire suppression capability, posing a safety risk. Operators, maintenance organizations, and compliance teams must address this to ensure continued airworthiness and regulatory compliance.
What To Do
Operators must replace each affected fire-extinguishing pipe with the redesigned part within 72 months of the directive's effective date, following Airbus Service Bulletin A380-26-8011 instructions. After replacement, installation of the old affected parts on the aircraft is prohibited. Stakeholders should monitor the consultation period and prepare for compliance once the directive is finalized.
