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) 2017-05-
12, which applied to certain Airbus SAS Model A318-112 airplanes; Model 
A319-111, -112, -115, -132, and -133 airplanes; Model A320-214, -232, 
and -233 airplanes; and Model A321-211, -212, -213, -231, and -232 
airplanes. AD 2017-05-12 required a one-time eddy current conductivity 
measurement of certain cabin, cargo compartment, and frame structural 
parts to determine if aluminum alloy with inadequate heat treatment was 
used, and replacement if necessary. This AD retains the requirements of 
AD 2017-05-12, and for certain airplanes, requires additional work, as 
specified in a European Union

SUPPLEMENTARY INFORMATION:

Discussion

    The EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2019-0196, dated August 14, 2019 
(``EASA AD 2019-0196'') (also referred to as the Mandatory Continuing 
Airworthiness Information, or ``the MCAI''), to correct an unsafe 
condition for certain Airbus SAS Model A318-112 airplanes; Model A319-
111, -112, -115, -132, and -133 airplanes; Model A320-214, -216, -232, 
and -233 airplanes; and Model A321-211, -212, -213, -231, and -232 
airplanes.
    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to supersede AD 2017-05-12, Amendment 39-18823 (82 FR 
13382, March 13, 2017) (``AD 2017-05-12''), which applied to certain 
Airbus SAS Model A318-112 airplanes; Model A319-111, -112, -115, -132, 
and -133 airplanes; Model A320-214, -232, and -233 airplanes; and Model 
A321-211, -212, -213, -231, and -232 airplanes. The NPRM published in 
the Federal Register on December 16, 2019 (84 FR 68376). The NPRM was 
prompted by a determination that aluminum alloy with inadequate heat 
treatment had been used for additional structural parts. The NPRM 
proposed to retain the requirements of AD 2017-05-12, and for certain 
airplanes, would require additional work. The FAA is issuing this AD to 
address structural parts made of aluminum alloy with inadequate heat 
treatment, which could result in reduced structural integrity of the 
airplane.

Comments

    The FAA gave the public the opportunity to participate in 
developing this final rule. The following presents the comment received 
on the NPRM and the FAA's response.

Request To Extend Compliance Time

    American Airlines (AAL) asked that the FAA extend the compliance 
time for the additional work required by paragraph (2) of EASA AD 2019-
0196. AAL asked that the compliance time be changed from within 108 
months to within 120 months (10 years) from the date of aircraft 
manufacture due to the nature of the work, and in order for affected 
airplanes to do the work at the next scheduled heavy maintenance check 
opportunity.
    The FAA does not agree with the commenter's request to extend the 
compliance time. AAL did not provide information showing that the 
revised compliance time would provide an adequate level of safety. The 
FAA has determined that the 108-month compliance time in EASA AD 2019-
0196 addresses the identified unsafe condition in a timely manner. In 
developing an appropriate compliance time, EASA considered the degree 
of urgency associated with addressing the subject unsafe condition, the 
average utilization of the affected fleet, and the time necessary to 
perform the additional work. The FAA has determined that the compliance 
time specified in EASA AD 2019-0196 represents an appropriate interval 
of time for affected airplanes to continue to operate without 
compromising safety. However, under the provisions of paragraph (i)(1) 
of this AD, the FAA will consider requests for approval of an extension 
of the compliance time if sufficient data are submitted to substantiate 
that the new compliance time would provide an acceptable level of 
safety. The AD has not been changed in this regard.

Conclusion

    The FAA has reviewed the relevant data, considered the comment 
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 2019-0196 describes procedures for a one-time eddy current 
conductivity measurement of certain cabin, cargo compartment, and frame 
structural parts to determine if aluminum alloy with inadequate heat 
treatment was used, and replacement if necessary. EASA AD 2019-0196 
also describes, for certain airplanes, additional work (a one-time eddy 
current conductivity measurement of certain other structural parts, and 
replacement if necessary). 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 63 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

[[Page 21761]]



                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
                                                                                                 Cost on U.S.
              Action                    Labor cost        Parts cost      Cost per product        operators
----------------------------------------------------------------------------------------------------------------
Retained actions from AD 2017-05-  6 work-hours x $85               $0  $510...............  $32,130.
 12.                                per hour = $510.
New actions......................  Up to 7 work-hours               $0  Up to $595.........  Up to $37,485.
                                    x $85 per hour =
                                    Up to $595.
----------------------------------------------------------------------------------------------------------------

    The FAA has received no definitive data that enables the agency to 
provide cost estimates for the on-condition actions specified in this 
AD.
    According to the manufacturer, some or all of the costs of this AD 
may be covered under warranty, thereby reducing the cost impact on 
affected individuals. The FAA does not control warranty coverage for 
affected individuals. As a result, the FAA has included all known costs 
in the cost estimate.

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.
