SUPPLEMENTARY INFORMATION:

Discussion

We 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
A318 and A319 series airplanes, Model A320-211, -212, -214, -216, -231,
-232, and -233 airplanes, and Model A321-111, -112, -131, -211, -212, -
213, -231, and -232 airplanes. The NPRM published in the Federal
Register on December 11, 2018 (83 FR 63598). The NPRM was prompted by a
report that taperloks used in a certain wing-to-fuselage junction were
found to be non-compliant with the applicable specification, resulting
in a loss of pre-tension in the fasteners. The NPRM proposed to require
repetitive special detailed inspections of the center and outer wing
box lower stiffeners and panels at a certain junction on the left- and
right-hand sides for any cracking, and repair if necessary, as
specified in, and in compliance with, EASA AD 2018-0218, dated October
11, 2018; corrected October 26, 2018 (``EASA AD 2018-0218''). The NPRM
also proposed, as specified in EASA AD 2018-0218, an optional
modification, which would terminate the repetitive inspections.
We are issuing this AD to address the loss of pre-tension in the
fasteners, which could affect the structural integrity of the airplane.
The EASA, which is the Technical Agent for the Member States of the
European Union, has issued EASA AD 2018-0218 (also referred to as the
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to
correct an unsafe condition for certain Airbus SAS Model A318 and A319
series airplanes, Model A320-211, -212, -214, -216, -231, -232, and -
233 airplanes, and Model A321-111, -112, -131, -211, -212, -213, -231,
and -232 airplanes. The MCAI states:

Taperloks used in the wing-to-fuselage junction at Rib 1 were
found to be non-compliant with the applicable specification,
resulting in a loss of pre-tension in the fasteners.
This condition, if not detected and corrected, could affect the
structural integrity of the aeroplane. To address this potential
unsafe condition, Airbus issued SB A320-57-1129 and SB A320-57-1130,
later revised twice, providing instructions for repetitive internal
inspections of the lower stiffeners and for repetitive external
inspections of the lower panels of the center and outer wing box at
the level of Rib 1 junction. Consequently, EASA issued AD 2007-0067,
later revised [which corresponds to FAA AD 2008-02-15, Amendment 39-
15345 (73 FR 4063, January 24, 2008) (``AD 2008-02-15'')], to
require accomplishment of these inspections.
Since EASA AD 2007-0067R1 was issued, new events and the results
of studies identified an aging effect on these parts. Prompted by
these findings, Airbus revised SB A320-57-1129 (now at Revision 05)
and A320-57-1130 (now at Revision 04), expanding the applicability,
modifying the area to be inspected and updating the inspection
intervals.
For the reasons stated above, this [EASA] AD retains the
requirements of EASA AD 2007-0067R1, which is superseded, expands
the Applicability, modifies the areas to be inspected and revises
the inspection thresholds and intervals.
This [EASA] AD is republished to correct typographical errors in
paragraph (2) and in Tables 1 and 3.

Comments

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

Conclusion

We 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. We have determined that these minor
changes:
<bullet> Are consistent with the intent that was proposed in the
NPRM for addressing the unsafe condition; and
<bullet> 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 2018-0218 describes procedures for repetitive special
detailed inspections of the center and outer wing box lower stiffeners
and panels at the level of rib 1 junction on the left- and right-hand
sides for any cracking, and repair if necessary. EASA AD 2018-0218 also
provides procedures for an optional modification, which would terminate
the repetitive inspections. 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
and it is publicly available through the EASA website.

Costs of Compliance

We estimate that this AD affects 516 airplanes of U.S. registry. We
estimate the following costs to comply with 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.
We are 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) Is not a ``significant rule'' under the DOT Regulatory Policies
and Procedures (44 FR 11034, February 26, 1979),
(3) Will not affect intrastate aviation in Alaska, and
(4) 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.
