Airworthiness Directives; Airbus SAS Airplanes

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

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2018-09-
09, which applied to certain Airbus Model A318 and A319 series 
airplanes; all Model A320-211, -212, -214, -216, -231, -232, and -233 
airplanes; and all Model A321-111, -112, -131, -211, -212, -213, -231, 
and -232 airplanes. AD 2018-09-09 required modifying the holes of the 
upper cleat to upper stringer attachments at certain areas of the left- 
and right-hand wings. Since the FAA issued AD 2018-09-09, additional 
affected configurations were identified and, for certain airplanes, it 
was determined that additional modification work and revised compliance 
times are necessary. This AD retains the requirements of AD 2018-09-09 
and adds airplanes, requires different compliance times for certain 
airplane configurations, and, for certain airplanes, requires 
additional modifications or reduces compliance times, 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 May 10, 2022.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of May 10, 
2022.

SUPPLEMENTARY INFORMATION: 

Background

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2021-0167, dated July 14, 2021 (EASA 
AD 2021-0167) (also referred to as the MCAI), to correct an unsafe 
condition for certain Airbus SAS Model A318-111, -112, -121, and -122 
airplanes; Model A319-111, -112, -113, -114, -115, -131, -132, and -133 
airplanes; Model A320-211, -212, -214, -215, -216, -231, -232, and -233 
airplanes; and Model A321-111, -112, -131, -211, -212, -213, -231, and 
-232 airplanes. Model A320-215 airplanes are not certificated by the 
FAA and are not included on the U.S. type certificate data sheet; this 
AD therefore does not include those airplanes in the applicability.
    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to supersede AD 2018-09-09, Amendment 39-19266 (83 FR 
19925, May 7, 2018; corrected May 15, 2018 (83 FR 22354)) (AD 2018-09-
09). AD 2018-09-09 applied to certain Airbus Model A318 and A319 series 
airplanes; all Model A320-211, -212, -214, -216, -231, -232, and -233 
airplanes; and all Model A321-111, -112, -131, -211, -212, -213, -231, 
and -232 airplanes. The NPRM published in the Federal Register on 
December 21, 2021 (86 FR 72195). The NPRM was prompted by a report 
indicating that additional affected configurations were identified to 
be subject to widespread fatigue damage and, for certain airplanes, it 
was determined that additional modification work (such as, for certain 
configurations, oversizing certain additional holes, replacing a 
certain fastener with a corrosion-resistant fastener, or cleat refit 
and sealant procedure) or revised compliance times are necessary. The 
NPRM proposed to retain the requirements of AD 2018-09-09 and add 
airplanes, require different compliance times for certain airplane 
configurations, and, for certain airplanes, require additional 
modifications or reduce compliance times, as specified in EASA AD 2021-
0167.
    The FAA is issuing this AD to prevent fatigue cracking in the 
stringer attachment holes of the wings, which could result in reduced 
structural integrity of the wings. See the MCAI for additional 
background information.

Discussion of Final Airworthiness Directive

Comments

    The FAA received comments from two commenters, Air Line Pilots 
Association, International (ALPA), and United Airlines, who supported 
the NPRM without change.

Conclusion

    The FAA reviewed the relevant data, considered the comments 
received, and determined that air safety requires adopting this AD as 
proposed. Except for minor editorial changes, this AD is adopted as 
proposed in the NPRM. None of the changes will increase the economic 
burden on any operator. Accordingly, the FAA is issuing this AD to 
address the unsafe condition on these products.

Related Service Information Under 1 CFR Part 51

    EASA AD 2021-0167 specifies procedures for modifying the stringer 
attachments at rib 2 through rib 7 of the left- and right-hand wings. 
The modification includes oversizing the holes, doing an eddy current 
inspection of the affected holes for damage, and repairing damage. EASA 
AD 2021-0167 also specifies additional work for airplanes on which the 
modification actions were accomplished using certain service 
information. 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 1,446 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
                                                                              Cost per

                                        hour = $10,625.                                   airplanes).
New actions..........................  125 work-hours x $85 per       1,520      12,145  $17,561,670.
                                        hour = $10,625.
----------------------------------------------------------------------------------------------------------------

    The FAA has received no definitive data on which to base the cost 
estimates for the on-condition actions or the additional work for 
certain previously modified airplanes, as 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.
