EASA AD 2020-0025
Nacelles / Pylons — Inboard and Outboard Pylon Drain System — Inspection / Modification
Summary
EASA Airworthiness Directive 2020-0025 is an airworthiness directive affecting Airbus A380-841 and A380-842 aeroplanes, excluding those with Airbus modifications 77710, 77711, 77712, and 77713 incorporated in production. It addresses inspection and modification requirements for the inboard and outboard pylon drain systems to prevent potential fire hazards caused by hydraulic fluid leakage and clogged drain lines near the engine pylons.
What Changed
This directive supersedes EASA AD 2019-0002 and retains the requirement for repetitive detailed inspections of the engine drain system flexible hoses. It introduces a mandatory modification of the drain routing on each engine pylon as a terminating action for the repetitive inspections. The directive also updates the applicable service bulletins for inspection and modification procedures.
Why It Matters
This directive is critical for aviation professionals because it mitigates the risk of on-ground fires caused by hydraulic fluid leaks accumulating near hot engine parts due to clogged drain lines. Compliance ensures continued airworthiness and safety of Airbus A380 aircraft, protecting both the aircraft and ground personnel. Operators and maintenance teams must monitor and maintain the pylon drain systems to prevent potential damage and operational disruptions.
What To Do
Operators must perform a detailed inspection of each engine drain system flexible hose within 3 months of 28 February 2020 and repeat the inspection every 12 months thereafter. If black residue is found, corrective actions must be taken before the next flight. Additionally, the drain routing modification must be completed within 34 months after the effective date to terminate the need for repetitive inspections.
