SUPPLEMENTARY INFORMATION: 

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2018-0288, dated December 21, 2018 (referred to after this as the 
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to 
correct an unsafe condition for all Airbus SAS Model A318, A319, A320 
and A321 series airplanes. Model A320-215 airplanes are not certified 
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. You may examine the MCAI in the AD docket on the 
internet at https://www.regulations.gov by searching for and locating 
Docket No. FAA-2019-0321.
    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 by adding an AD that would apply to all Airbus SAS Model 
A318 series airplanes; A319-111, -112, -113, -114, -115, -131, -132, 
and -133 airplanes; A320-211, -212, -214, -216, -231, -232, -233, -
251N, -252N and -271N airplanes; and A321 series airplanes. The NPRM 
published in the Federal Register on May 9, 2019 (84 FR 20303). 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. The 
FAA is issuing this AD to address fatigue cracking, accidental damage, 
or corrosion in principal structural elements, which could result in 
reduced structural integrity of the airplane. See the MCAI for 
additional background information.

Comments

    The FAA gave the public the opportunity to participate in 
developing this final rule. The following presents the comments 
received on the NPRM and the FAA's response to each comment. Delta 
Airlines (DAL) stated that it supports the NPRM.

Request for a Reporting Requirement

    DAL requested that we add a reporting requirement to the proposed 
AD. DAL recommended that the proposed AD state that all crack findings, 
along with corrective actions performed, be reported to Airbus via the 
Airbus Tech Request system within 30 days. DAL commented that the 
philosophy of the fatigue-related inspections is that they are in 
places where cracking might be found in the future, and if cracking is 
found, then the task in Airbus A318/A319/A320/A321 Airworthiness 
Limitations Section (ALS) Part 2--Damage Tolerant Airworthiness 
Limitation Items (DT-ALI), Revision 07, dated June 13, 2018, will be 
removed and become its own service information and AD; therefore, 
mandatory reporting must be part of this process. DAL also stated that 
they could not locate information regarding where to submit reports and 
the timeframe for reporting.
    The FAA would like to clarify the intent of the referenced damage-
tolerant task in Airbus A318/A319/A320/A321 Airworthiness Limitations 
Section (ALS) Part 2--Damage Tolerant Airworthiness Limitation Items 
(DT-ALI), Revision 07, dated June 13, 2018. Unlike airplanes that 
follow a Supplemental Structural Inspection Program that requires 
reporting (those with an older certification basis that does not 
include damage tolerance criteria), the airplanes specified in 
paragraph (c) of this AD comply with 14 CFR 25.571 damage tolerance 
criteria. Section 25.571 requires applicants to evaluate all structures 
that could contribute to catastrophic failure of the airplane with 
respect to its susceptibility to fatigue cracking, corrosion, and 
accidental damage. Applicants must establish inspections or other 
procedures (also referred to as maintenance actions) as necessary to 
avoid catastrophic failure during the operational life of the airplane 
based on the results of these evaluations. It is intended that all 
maintenance actions required to address fatigue cracking, corrosion, 
and accidental damage are identified in the structural-maintenance 
program. All inspections and other procedures (e.g., modification 
times, replacement times) that are necessary to prevent a catastrophic 
failure due to fatigue are included in the Airworthiness Limitations 
Section (ALS) of the Instructions for Continued Airworthiness (ICA), as 
required by 14 CFR 25.1529. Therefore, reporting is not needed to 
comply with this AD.
    FAA Advisory Circular 25.571-1D provides guidance for compliance 
with the provisions of 14 CFR 25.571, pertaining to the requirements 
for damage-tolerance and fatigue evaluation of transport category 
aircraft structure, and may be referenced for further information.
    While airplane manufacturers may benefit from receiving information 
from the outcome of the ALI inspections, the EASA did not make 
reporting a requirement in EASA AD 2018-0288. The FAA concurs with the 
EASA, and therefore, this AD does not include a reporting requirement. 
However, operators may report the findings, as an option, to Airbus as 
specified in paragraph 6., ``Reporting,'' of Section 1 of Airbus A318/
A319/A320/A321 Airworthiness Limitations Section (ALS) Part 2--Damage 
Tolerant Airworthiness Limitation Items (DT-ALI), Revision 07, dated 
June 13, 2018, that indicates reports should be sent to 
MPDtask.Reports@airbus.com. This AD has not been changed in this 
regard.

Request To Add an Alternative Methods of Compliance (AMOC)

    Airbus requested that AIR-676-19-235, dated June 3, 2019, which is 
an AMOC for paragraphs (g) and (l)(2)(i) of AD 2018-25-02, Amendment 
39-19513 (83 FR 62690, December 6, 2018), be allowed as an AMOC for the 
requirements of paragraph (j) of the proposed AD.
    The FAA agrees with the commenter's request. The agency finds that 
the provisions of AMOC AIR-676-19-235, which is limited to certain 
airplanes, are acceptable for all corresponding provisions of this AD. 
Therefore, the FAA has added paragraph (j)(1)(iii) to this AD to allow 
AIR-676-19-235, dated June 3, 2019, as an acceptable method of 
compliance for the corresponding provisions of this AD.

[[Page 66581]]

Changes Made to This Final Rule

    The FAA has determined that Airbus SAS Model A320-252N airplanes 
were inadvertently omitted from the Applicability of the proposed AD. 
Therefore, the FAA has updated paragraph (c)(3) of this AD to add those 
airplanes. Since there are currently no domestic operators of this 
product, additional notice and opportunity for public comment before 
issuing this AD are unnecessary.

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 with the change described previously 
and 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.
    The FAA also determined that these changes will not increase the 
economic burden on any operator or increase the scope of this final 
rule.

Related Service Information Under 1 CFR Part 51

    Airbus has issued Airbus A318/A319/A320/A321 Airworthiness 
Limitations Section (ALS) Part 2--Damage Tolerant Airworthiness 
Limitation Items (DT-ALI), Revision 07, dated June 13, 2018. This 
service information describes damage tolerant airworthiness 
limitations. This service information 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 1,463 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:
    The FAA has determined that revising the existing 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 FAA 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. Therefore, the FAA estimates the total cost per 
operator 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.
    This AD is issued in accordance with authority delegated by the 
Executive Director, Aircraft Certification Service, as authorized by 
FAA Order 8000.51C. In accordance with that order, issuance of ADs is 
normally a function of the Compliance and Airworthiness Division, but 
during this transition period, the Executive Director has delegated the 
authority to issue ADs applicable to transport category airplanes and 
associated appliances to the Director of the System Oversight Division.

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.
