What to do
Affected operators must modify the electrical installations in both wings within 36 months after 19 February 2014, or within 48 months for certain aircraft depending on previous service bulletin embodiment. Additional work must be completed within 12 months after the effective date of this AD for specific groups of A300-600 aeroplanes. Compliance involves following the instructions in the applicable Airbus Service Bulletins, including revisions 04 and 05 of SB A300-24-6103 and others as specified.
Summary
EASA Airworthiness Directive 2019-0014 is an official regulatory document addressing electrical power wing installation modifications for Airbus A300-600, A300-600ST, and A310 aeroplanes. It mandates modifications to the wing electrical installations to prevent damage caused by insufficient clearance and potential chafing of electrical harnesses. The directive applies to all certified models and serial numbers of these aircraft types.
What changed
This directive supersedes EASA AD 2016-0172 and retains its requirements while introducing additional work for certain A300-600 aeroplanes. It requires implementing Airbus Service Bulletin revisions that improve wing electrical installation clearance and protection, including installation of new bracket assemblies, protective sleeves, and clamps. The latest revision clarifies additional work related to spacers and clamp modifications that were previously unclear.
Why it matters
This directive is critical for aviation professionals because it addresses a safety risk involving potential damage to wing electrical harnesses and surrounding structure, which could compromise aircraft safety. Operators and maintenance organizations must ensure compliance to maintain airworthiness and avoid operational restrictions. The directive also provides clear guidance on acceptable service bulletin revisions and additional work to ensure proper installation and protection of electrical systems.
