AD 2020-26-18 Requires Replacing Each Affected Fillet Fairing Adjustable Rod

The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A330-243, -343, and -941 airplanes.

This AD was prompted by a report that during an inspection of the wing/fuselage fillet interface, evidence of black stains and white oxidation was found on several areas of the fillet fairing adjustable rods due to surface corrosion. This AD requires replacing each affected fillet fairing adjustable rod with a serviceable part, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products. This AD becomes effective January 14, 2021.

Supplementary Information: The EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2020-0209, dated October 5, 2020 (EASA AD 2020-0209) (also referred to as the Mandatory Continuing Airworthiness Information, or the MCAI), to correct an unsafe condition for certain Airbus SAS Model A330-243, -343, and -941 airplanes.

This AD was prompted by a report that during an inspection of the wing/fuselage fillet interface, evidence of black stains and white oxidation was found on several areas of the fillet fairing adjustable rods due to surface corrosion. The FAA is issuing this AD to address surface corrosion, which could lead to rod failures and consequent fillet fairing detachment, and possibly result in damage to the tailplane and reduced control of the airplane. See the MCAI for additional background information.
