What to do
Operators of Airbus A350-941 and A350-1041 aeroplanes must identify if affected cargo door seals are installed and replace them with serviceable parts within 12 months of the directive's effective date. Maintenance teams must cease using the specified maintenance procedure on all aircraft and avoid installing affected parts or cargo doors. Replacement can be performed by following Airbus Service Bulletin A350-52-P078 instructions.
Summary
EASA Airworthiness Directive Proposal 26-124 addresses inspection and replacement of forward and aft cargo door seals on Airbus A350-941 and A350-1041 aeroplanes. The directive targets specific cargo door seals with part numbers V0007007220200 and V0007007320200 that have been repaired using a maintenance procedure incorrectly published as a permanent repair. This proposal aims to ensure the integrity of cargo compartment fire extinguishing systems by mandating replacement of affected seals.
What changed
This new proposed airworthiness directive introduces a requirement to replace affected cargo door seals that were repaired using a temporary maintenance procedure mistakenly treated as permanent. It prohibits further maintenance using the flawed procedure and bans installation of affected parts or cargo doors containing them. The directive also provides acceptable compliance methods including replacement of entire cargo doors.
Why it matters
This directive is critical for maintaining the airtightness and halon retention capability of cargo compartments, which directly impacts the effectiveness of fire extinguishing systems. Operators and maintenance organizations must comply to prevent potential fire safety failures. Compliance ensures continued airworthiness and regulatory adherence for Airbus A350 operators.
