Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are superseding Airworthiness Directive (AD) 2017-07-07, 
which applied to certain Airbus Model A330-200, A330-300, A340-200, and 
A340-300 series airplanes. AD 2017-07-07 required repetitive 
inspections of certain fastener holes, and related investigative and 
corrective actions if necessary. This AD retains the requirements of AD 
2017-07-07 and expands the applicability. This AD was prompted by a 
report of cracking at fastener holes located at frame (FR) 40 on the 
lower shell panel junction. We are issuing this AD to address the 
unsafe condition on these products.

DATES: This AD is effective August 22, 2018.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of August 22, 
2018.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 2017-07-07, Amendment 39-18845 (82 FR 18547, 
April 20, 2017) (``AD 2017-07-07''). AD 2017-07-07 applied to certain 
Airbus Model A330-200, A330-300, A340-200, and A340-300 series 
airplanes with manufacturer serial numbers (MSN) 0176 through 0915 
inclusive. The NPRM published in the Federal Register on February 20, 
2018 (83 FR 7117). The NPRM was prompted by a report of cracking at 
fastener holes located at frame FR40 on the lower shell panel junction. 
The NPRM proposed to retain the requirements of AD 2017-07-07 and 
expand the applicability. We are issuing this AD to detect and correct 
cracking at FR40 on the lower shell panel junction; such cracking could 
lead to reduced structural integrity of the fuselage.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2017-0063, dated April 12, 2017 (referred to after this as the 
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to 
correct an unsafe condition for certain Airbus Model A330-200, A330-
300, and A340-200 series airplanes, and Model A340-312 and -313 
airplanes. The MCAI states:

    During full scale fatigue test of the Frame (FR) 40 to fuselage 
skin panel junction, fatigue damage was found. Corrective actions 
consisted of in-service installation of an internal reinforcing 
strap on the related junction, as currently required by DGAC 
[Direction G[eacute]n[eacute]rale de l'Aviation Civile] France AD 
1999-448-126(B), which refers to Airbus Service Bulletin (SB) A340-
53-4104 Revision 02, and [DGAC] AD 2001-070(B), which refers to 
Airbus SB A330-53-3093 Revision 04; retrofit improvement of internal 
reinforcing strap fatigue life through recommended Airbus SB A330-
53-3145; and

[[Page 33822]]

introducing a design improvement in production through Airbus mod 
44360.
    After those actions were implemented, cracks were found on both 
left-hand (LH) and right-hand (RH) sides on internal strap, butt 
strap, keel beam fitting, or forward fitting FR40 flange. These 
findings were made during embodiment of a FR40 web repair on an A330 
aeroplane, and during keel beam replacement on an A340 aeroplane, 
where the internal strap was removed and a special detailed 
inspection (SDI) was performed on several holes.
    This condition, if not detected and corrected, could affect the 
structural integrity of the centre fuselage of the aeroplane.
    Prompted by these findings, Airbus issued SB A330-53-3215 and SB 
A340-53-4215, providing inspection instructions. Consequently, EASA 
issued AD 2014-0136 [which corresponds to FAA AD 2017-07-07] to 
require repetitive SDI (rototest) of 10 fastener holes located at 
the FR40 lower shell panel junction on both LH and RH sides and, 
depending on findings, accomplishment of applicable corrective 
action(s).
    Since that [EASA] AD was issued, prompted by the results of 
complementary fatigue analyses, it was determined that post-mod 
55792 aeroplanes could be also affected by crack initiation and 
propagation at this area of the fuselage. These analyses 
demonstrated that post-mod 55792 aeroplanes must follow the same 
maintenance program as aeroplanes in post-mod 55306 and pre-mod 
55792 configuration. Consequently, Airbus published SB A330-53-3215 
Revision 02 and SB A340-53-4215 Revision 02 to expand the 
Effectivity accordingly.
    For the reasons described above, this [EASA] AD retains the 
requirements of EASA AD 2014-0136, which is superseded, which now 
also apply to aeroplanes in post-mod 55792 configuration [the 
applicability identifies airplanes in post-mod 44360 configuration].

    AD 2017-07-07 includes Model A340-211 airplanes in its 
applicability. Airbus Model A340-211 airplanes are not identified in 
the applicability of this AD because those airplanes are not affected 
by the identified unsafe condition. All of those airplanes are in the 
pre-Airbus modification 44360 configuration. The MCAI also does not 
include Model A340-211 airplanes in its applicability.
    The compliance time ranges between 20,000 flight cycles or 65,400 
flight hours and 20,800 flight cycles or 68,300 flight hours, depending 
on airplane utilization and configuration. The repetitive inspection 
interval ranges between 14,000 flight cycles or 95,200 flight hours and 
24,600 flight cycles or 98,700 flight hours, depending on airplane 
utilization and configuration. 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-2018-0111.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We considered the comment received. Kenneth Ciallella 
supported the NPRM.

Explanation of Changes Made to This AD

    We have revised this AD to refer to Airbus Service Bulletin A330-
53-3215, Revision 03, dated January 22, 2018, as the appropriate source 
of service information for the required actions. This service 
information incorporates minor editorial changes which have no effect 
on airplanes that have incorporated prior revisions of this service 
information. We have revised table 1 to paragraph (g)(1) of this AD and 
paragraphs (g), (g)(1), (g)(2), (h), (h)(1), (h)(2), and (i) of this AD 
to specify Airbus Service Bulletin A330-53-3215, Revision 03, dated 
January 22, 2018, as the appropriate source of service information for 
accomplishing the required actions in those paragraphs.
    We have revised paragraph (j) of this AD to give credit for using 
Airbus Service Bulletin A330-53-3215, Revision 02, dated November 23, 
2016, to accomplish the required actions before the effective date of 
this AD.

Conclusion

    We reviewed the available data, including the comments received, 
and determined that air safety and the public interest require adopting 
this AD as proposed except for the changes described previously and 
minor editorial changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for correcting 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 Airbus Service Bulletin A330-53-3215, Revision 
03, dated January 22, 2018 (``A330-53-3215, R3'') and Airbus Service 
Bulletin A340-53-4215, Revision 02, dated November 23, 2016. This 
service information describes procedures for repetitive rototest 
inspections of certain fastener holes, and related investigative and 
corrective actions if necessary. 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.

Costs of Compliance

    We estimate that this AD affects 99 airplanes of U.S. registry. We 
estimate the following costs to comply with this AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
                                                                                    Cost per       Cost on U.S.
                          Labor cost                              Parts cost        product         operators

----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary repairs that 
would be required based on the results of the required inspections. We 
have no way of determining the number of aircraft that might need these 
repairs:

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 to 
the Director of the System Oversight Division.

Regulatory Findings

    We determined that 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.
