AGENCY:

Federal Aviation Administration (FAA), Department of Transportation (DOT).

ACTION:

Final rule.

SUMMARY:

The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A320-214, -232, and -271N airplanes, and Model A321-231 airplanes. This AD was prompted by a report of a production line inspection finding of damage on a main landing gear (MLG) side stay attachment outboard lug. This AD requires an inspection for discrepancies of the MLG side stay attachment outboard lugs, left-hand and right-hand sides, and applicable corrective action, 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.

DATES:

This AD is effective April 20, 2020.

The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of April 20, 2020.

SUPPLEMENTARY INFORMATION:

Discussion

The EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2019-0167, dated July 15, 2019 (“EASA AD 2019-0167”) (also referred to as the Mandatory Continuing Airworthiness Information, or “the MCAI”), to correct an unsafe condition for certain Airbus SAS Model A320-214, -232, and -271N airplanes, and Model A321-231 airplanes.

The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain Airbus SAS Model A320-214,-232, and -271N airplanes, and Model A321-231 airplanes. The NPRM published in the Federal Register on November 1, 2019 (84 FR 58634). The NPRM was prompted by report of a production line inspection finding of damage on a MLG side stay attachment outboard lug. Investigation results determined that the detected damage had been caused by using incorrect tooling, and identified a batch of affected parts that may have received the same treatment. The NPRM proposed to require an inspection for discrepancies of the MLG side stay attachment outboard lugs, left-hand and right-hand sides, and applicable corrective action as specified in an EASA AD.

The FAA is issuing this AD to address damaged MLG side stay attachment outboard lugs, which could reduce the structural integrity of the attachment of the MLG to the wing. See the MCAI for additional background information.

Comments

The FAA gave the public the opportunity to participate in developing this final rule. The FAA has considered the comments received. Air Line Pilots Association, International (ALPA) and Darcy Mraz support the intent of the NPRM.

Conclusion

The FAA reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting this final rule as proposed, except for minor editorial changes. The FAA has determined that these minor changes:

• Are consistent with the intent that was proposed in the NPRM for addressing the unsafe condition; and
• Do not add any additional burden upon the public than was already proposed in the NPRM.

Related IBR Material Under 1 CFR Part 51

EASA AD 2019-0167 describes procedures for an inspection for discrepancies (cracks, wear, damage, and corrosion) of the MLG side stay attachment outboard lugs, left-hand and right-hand sides, and corrective action (repair). This material is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section.

Costs of Compliance

The FAA estimates that this AD affects 1 airplane of U.S. registry. The FAA estimates the following costs to comply with this AD:

Estimated Costs for Required Actions

Labor cost	Parts cost	Cost per product	Cost on U.S. operators
121 work-hours × $85 per hour = $10,285	$0	$10,285	$10,285

The FAA has received no definitive data that would enable the FAA to provide cost estimates for the on-condition actions specified in this AD.

Authority for This Rulemaking

Title 49 of the United States Code specifies the FAA's authority to issue rules on aviation safety. Subtitle I, section 106, describes the authority of the FAA Administrator. Subtitle VII: Aviation Programs, describes in more detail the scope of the Agency's authority.

The FAA is issuing this rulemaking under the authority described in Subtitle VII, Part A, Subpart III, Section 44701: “General requirements.” Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action.

Regulatory Findings

This AD will not have federalism implications under Executive Order 13132. This AD will not have a substantial direct effect on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government.

For the reasons discussed above, I certify that this AD:

(1) Is not a “significant regulatory action” under Executive Order 12866,

(2) Will not affect intrastate aviation in Alaska, and

(3) Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.

List of Subjects in 14 CFR Part 39

• Air transportation
• Aircraft
• Aviation safety
• Incorporation by reference
• Safety

Adoption of the Amendment

Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows:
