EASA AD US-2022-04-08
Fire Protection / Doors — Cargo Door Seals — Replacement / Operational Limitation / Placard Installation
Summary
Federal Aviation Administration Airworthiness Directive 2022-04-08 is a final rule addressing Airbus SAS Model A318, A319, A320, and A321 series airplanes. It focuses on fire protection related to cargo door seals, specifically requiring replacement of certain forward and aft cargo compartment door seals and installation of placards. The directive also mandates operational limitations for certain routes via revisions to the airplane flight manual.
What Changed
This AD supersedes AD 2020-16-01 by retaining repetitive cleaning and greasing requirements while introducing mandatory replacement of specific cargo door seals with improved versions. It requires installation of placards on cargo compartment doors and, for some airplanes, revising the flight manual to implement operational limitations. The applicability is limited to airplanes with certain parts manufacturer approval (PMA) parts installed.
Why It Matters
The directive addresses low halon concentration in cargo compartments caused by air leakage through door seals, which could compromise fire extinguishing system effectiveness. Compliance ensures enhanced fire safety in cargo areas, reducing the risk of uncontrolled fires. Operators, maintenance organizations, and compliance teams must update procedures and manuals to meet these safety requirements and avoid operational restrictions.
What To Do
Affected operators must replace the specified forward and aft cargo door seals with new improved seals and install the required placards on cargo compartment doors by the effective date. For certain airplanes, the existing airplane flight manual must be revised to include operational limitations for specific routes. The AD becomes effective on April 11, 2022, and compliance with all requirements must be achieved by that date.
