SUPERSEDED BY EASA AD 2021-0049
Summary
EASA Airworthiness Directive 2020-0133 is an airworthiness directive issued by the European Union Aviation Safety Agency affecting Airbus A318, A319, A320, and A321 aeroplanes. It addresses the issue of air leakage through certain cargo door seals that could reduce the effectiveness of the cargo compartment fire extinguishing system. The directive applies to specific part numbers of forward, aft, and bulk cargo door seals installed on these aircraft models.
What Changed
This directive introduces mandatory repetitive cleaning and greasing of affected cargo door seals to prevent air leakage that compromises fire protection. It also prohibits the installation of affected parts on aircraft that do not currently have them installed. The directive is considered an interim action and may be followed by further regulatory measures.
Why It Matters
This directive is critical for maintaining the effectiveness of the cargo compartment fire extinguishing system, ensuring safety in the event of a fire. Operators, maintenance organizations, and compliance teams must adhere to these requirements to avoid potential fire suppression failures and to remain compliant with continuing airworthiness regulations. Failure to comply could result in unsafe operating conditions and regulatory penalties.
What To Do
Operators of affected Airbus A318, A319, A320, and A321 aeroplanes must clean and grease the specified cargo door seals within six months after the aircraft's date of manufacture or within three months after the directive's effective date, whichever is later, and repeat this every six months thereafter. For aircraft without affected parts installed, the installation of such parts is prohibited from the directive's effective date. Compliance with Airbus Technical Adaptation 80774334/003/2020 is required.
