We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A330-200, A330-300, A340-200, and A340-300 series airplanes. This proposed AD was prompted by a report of cracking at fastener holes located at a certain frame on the lower shell panel junction. This proposed AD would require repetitive inspections of certain fastener holes, and related investigative and corrective actions if necessary. We are proposing this AD to detect and correct cracking on the lower shell panel junction; such cracking could lead to reduced structural integrity of the fuselage.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2014-0136, dated June 13, 2014 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for certain Airbus Model 
A330, A340-200, and A340-300 series airplanes. The MCAI states:

    During A330/A340 aeroplanes full scale fatigue test specimen in 
the FR40-to-fuselage skin panel junction, fatigue damage has been 
found. Corrective actions consisted of the following actions:

--In-service installation of an internal reinforcing strap on 
related junction required by DGAC [Direction G[eacute]n[eacute]rale 
de l'Aviation Civile (DGAC)] France AD 1999-448-126(B) and AD 2001-
070(B),
--retrofit improvement of internal reinforcing strap fatigue life 
through recommended Airbus Service Bulletin (SB) A330-53-3145, and
--new design in production through Airbus modification 44360.

    The aeroplanes listed in the Applicability section of this AD 
are all aeroplanes post-mod 44360 and pre-mod 55792 (fuselage 
reinforcement at FR40 in production).
    Recently, during embodiment of a FR40 web repair on an A330 
aeroplane and during FR40 keel beam fitting replacement on an A340 
aeroplane, the internal strap was removed and rototest inspection 
was performed on several holes.
    Cracks were found on both left-hand (LH) and right-hand (RH) 
sides on internal strap, or butt strap, or keel beam fitting, or 
forward fitting FR40 flange.
    This condition, if not detected and corrected, could lead to 
crack propagation, possibly resulting in reduced structural 
integrity of the fuselage.
    For the reasons described above, this [EASA] AD requires 
repetitive rototest inspections of 10 fastener holes located at FR40 
lower shell panel junction on both LH and RH sides, and, depending 
on findings, accomplishment of the applicable corrective actions 
[which include oversizing, installing

[[Page 73358]]

fasteners and repair; and accomplishment of applicable related 
investigative actions, which include a rototest inspection for 
cracking after oversizing].

    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 
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-2016-9192.

Related Service Information Under 1 CFR Part 51

    We reviewed Airbus Service Bulletin A330-53-3215, Revision 01, 
dated April 17, 2014; and Airbus Service Bulletin A340-53-4215, 
Revision 01, dated April 17, 2014. The service information describes 
procedures for repetitive rototest inspections of certain fastener 
holes, 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.

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with the State of Design Authority, we have 
been notified of the unsafe condition described in the MCAI and service 
information referenced above. We are proposing this AD because we 
evaluated all pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of these 
same type designs.

Costs of Compliance

    We estimate that this proposed AD affects 41 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

                                                                     Estimated Costs

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

    We estimate the following costs to do any necessary repairs that 
would be required based on the results of the proposed inspection. We 
have no way of determining the number of airplanes 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.

Regulatory Findings

    We determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 this proposed 
regulation:
    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.
