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 all Airbus SAS Model A330-
200 Freighter series airplanes, Model A330-200 and -300 series 
airplanes, and Model A340-200 and -300 series airplanes. The NPRM 
published in the Federal Register on May 29, 2018 (83 FR 24427). The 
NPRM was prompted by reports of cracked slat tracks at the location of 
the front stop attachment to the track. The NPRM proposed to require a 
detailed inspection, repetitive special detailed inspections, and 
corrective actions if necessary.
    We are issuing this AD to address cracked slat tracks which could 
affect the structural integrity of the slat surface, possibly leading 
to detachment of an outer or inner slat surface, and resulting in 
reduced control of the airplane.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2017-0060, dated April 7, 2017 (referred to after this as the Mandatory 
Continuing Airworthiness Information, or ``the MCAI''), to correct an 
unsafe condition for all Airbus SAS Model A330-200 Freighter series 
airplanes; Model A330-200 and -300 series airplanes; and Model A340-200 
and -300 series airplanes. The MCAI states:

    Several cases of cracked slat tracks at the location of front 
stop attachment to track have been reported by operators. Analysis 
of the affected slat tracks (Airbus pre-modification (mod) 45967 
design) revealed that induced torque loads during normal 
installation of the front stop, in combination with an incorrect 
shaft length of the attachment bolts and geometry of the front stop, 
are the root cause.
    This condition, if not detected and corrected, would affect the 
structural integrity of the slat surface, which could lead to 
detachment of an outer or inner slat surface, possibly resulting in 
reduced control of the aeroplane and/or injury to persons on the 
ground.
    To address this potential unsafe condition, Airbus issued 
Service Bulletin (SB) A330-57-3123 and SB A340-57-4130, to provide 
inspection instructions.
    For the reasons described above, this [EASA] AD requires a one-
time detailed inspection (DET) of the front stop lateral and aft 
surfaces [for marks (dents or scratches),] and repetitive special 
detailed inspections (SDI) of the front stop attachment areas, of 
slat tracks number (No.) 5 to No. 16 inclusive, both left hand (LH) 
and right hand (RH) wings [for cracks], and, depending on findings, 
accomplishment of applicable corrective action(s) [corrective 
actions include rework, repair, and slat rigging].
    This [EASA] AD also includes reference to an optional 
modification (Airbus mod 205378) of the affected slat tracks, for 
which the associated SBs (SB A330-57-3126 and SB A340-57-4133, as 
applicable) are expected to become available in July 2017, which 
constitutes terminating action for the repetitive inspections 
required by this [EASA] AD.

    You may examine the MCAI in the AD docket on the internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2018-
0454.

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:
     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 Service Information Under 1 CFR Part 51

    Airbus has issued Service Bulletin A330-57-3123, Revision 01, dated 
September 27, 2017; and Service Bulletin A340-57-4130, Revision 01, 
dated September 27, 2017. This service information describes procedures 
for a detailed inspection of the front stop lateral and aft surfaces 
for marks (dents or scratches), repetitive special detailed inspections 
of the front stop attachment areas, of slat track numbers 5 to 16 
inclusive, both LH and RH wings for cracks, and corrective actions. 
These documents are distinct since they apply to different airplane 
models.
    Airbus has also issued Service Bulletin A330-57-3126, dated 
December 21, 2017; and Service Bulletin A340-57-4133, dated December 
21, 2017. This service information describes procedures for 
modification of all affected slat tracks on an airplane. These 
documents are distinct since they apply to different airplane models.
    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.

Paperwork Reduction Act

    A federal agency may not conduct or sponsor, and a person is not 
required to respond to, nor shall a person be subject to penalty for 
failure to comply with a collection of information subject to the 
requirements of the Paperwork Reduction Act unless that collection of

[[Page 45541]]

information displays a current valid OMB control number. The control 
number for the collection of information required by this AD is 2120-
0056. The paperwork cost associated with this AD has been detailed in 
the Costs of Compliance section of this document and includes time for 
reviewing instructions, as well as completing and reviewing the 
collection of information. Therefore, all reporting associated with 
this AD is mandatory. Comments concerning the accuracy of this burden 
and suggestions for reducing the burden should be directed to the FAA 
at 800 Independence Ave. SW, Washington, DC 20591, ATTN: Information 
Collection Clearance Officer, AES-200.

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.
