SUPPLEMENTARY INFORMATION:

Discussion

    The EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2019-0288, dated November 28, 2019 
(``EASA AD 2019-0288'') (also referred to as the Mandatory Continuing 
Airworthiness Information, or ``the MCAI''), to correct an unsafe 
condition for all Airbus SAS Model A350-941 and -1041 airplanes.
    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to supersede AD 2019-03-11, Amendment 39-19563 (84 FR 5584, 
February 22, 2019) (``AD 2019-03-11''). AD 2019-03-11 applied to 
certain Airbus SAS Model A350-941 and -1041 airplanes. The NPRM 
published in the Federal Register on April 10, 2020 (85 FR 20206). The 
NPRM was prompted by a determination that new or more restrictive 
airworthiness limitations are necessary. The NPRM proposed to require 
revising the existing maintenance or inspection program, as applicable, 
to incorporate new or more restrictive airworthiness limitations, as 
specified in an EASA AD.
    The FAA is issuing this AD to address safety-significant latent 
failures that would, in combination with one or more other specific 
failures or events, result in a hazardous or catastrophic failure 
condition. See the MCAI for additional background information.

Comments

    The FAA gave the public the opportunity to participate in 
developing this final rule. The FAA received no comments on the NPRM or 
on the determination of the cost to the public.

Conclusion

    The FAA reviewed the relevant data 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 2019-0288 describes airworthiness limitations for 
certification maintenance requirements.
    This AD also requires Airbus A350 Airworthiness Limitations Section 
(ALS) Part 3, Certification Maintenance Requirements (CMR), Revision 
04, dated December 15, 2017; and Airbus A350 ALS Part 3, Certification 
Maintenance Requirements (CMR), Variation 4.2, dated July 26, 2018, 
which the Director of the Federal Register approved for incorporation 
by reference as of March 29, 2019 (84 FR 5584, February 22, 2019).
    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 13 airplanes of U.S. 
registry.
    The FAA estimates the following costs to comply with this AD:

[[Page 53157]]

    The FAA estimates the total cost per operator for the retained 
actions from AD 2019-03-11 to be $7,650 (90 workhours x $85 per work-
hour).
    The FAA has determined that revising the maintenance or inspection 
program takes an average of 90 work-hours per operator, although the 
agency recognizes that this number may vary from operator to operator. 
In the past, the agency has estimated that this action takes 1 work-
hour per airplane. Since operators incorporate maintenance or 
inspection program changes for their affected fleet(s), the FAA has 
determined that a per-operator estimate is more accurate than a per-
airplane estimate. The FAA estimates the total cost per operator for 
the new actions to be $7,650 (90 work-hours x $85 per work-hour).

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.
