Federal Register Volume 81, Issue 174 (September 8, 2016)

We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A300 B4-600R series airplanes, Model A300 C4-605R Variant F airplanes, and Model A300 F4-600R series airplanes. This proposed AD was prompted by the results of a full stress analysis of the lower area of a certain frame that revealed a crack could occur in the forward fitting lower radius of a certain frame after a certain number of flight cycles. This proposed AD would require an inspection of the lower area of a certain frame radius for cracking, and corrective action if necessary. We are proposing this AD to detect and correct cracking in the forward fitting lower radius of a certain frame. Such cracking could reduce the structural integrity of the fuselage.

Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain Airbus Model A300 B4-600R series airplanes, Model A300 C4-605R 
Variant F airplanes, and Model A300 F4-600R series airplanes. This 
proposed AD was prompted by the results of a full stress analysis of 
the lower area of a certain

frame that revealed a crack could occur in the forward fitting lower 
radius of a certain frame after a certain number of flight cycles. This 
proposed AD would require an inspection of the lower area of a certain 
frame radius for cracking, and corrective action if necessary. We are 
proposing this AD to detect and correct cracking in the forward fitting 
lower radius of a certain frame. Such cracking could reduce the 
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 2016-0085, dated April 28, 2016 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for certain Airbus Model 
A300 B4-600R series airplanes, Model A300 C4-605R Variant F airplanes, 
and Airbus Model A300 F4-600R series airplanes. The MCAI states:

    Following a recently completed full stress analysis of the Frame 
(FR) 40 lower area, supported by a Finite Element Model (FEM), of 
the post-mod 10221 configuration, it was demonstrated that for the 
FR40 forward fitting lower radius, a crack could occur after a 
certain amount of flight cycles (FC).
    This condition, if not detected and corrected, could reduce the 
structural integrity of the fuselage.
    To address this potential unsafe condition, Airbus established 
that crack detection could be performed through a special detail 
inspection (SDI) using a high frequency eddy current (HFEC) method, 
and issued Alert Operators Transmission (AOT) A57W009-16.
    For the reasons described above, this AD requires a one-time SDI 
of the FR40 lower area and, depending on findings, accomplishment of 
applicable corrective action(s).

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-
9055.

Related Service Information Under 1 CFR Part 51

    We reviewed Airbus Alert Operators Transmission--AOT A57W009-16, 
Rev 00, dated February 25, 2016, including Appendixes 1 and 2, both 
undated. The service information describes procedures for inspecting 
the forward fitting lower radius of FR40 for cracking and corrective 
action. 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.

Clarification of Applicability

    The MCAI lists Airbus Model A300 B4-622R airplanes twice in the 
applicability. We have discussed the applicability with EASA, and the 
second reference was a typographical error which should have been 
``Airbus Model A300 F4-622R airplanes.'' The applicability of this 
proposed AD will include Airbus Model A300 F4-622R airplanes.

Costs of Compliance

    We estimate that this proposed AD affects 94 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                     Cost per      Cost on U.S.
                Action                         Labor cost           Parts cost        product        operators

                                         hour = $85.
----------------------------------------------------------------------------------------------------------------
We have received no definitive data that would enable us to provide cost estimates for the on-condition actions
  specified in this proposed AD.

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 
information displays a current valid OMB control number. The control 
number for the collection of information required by this proposed AD 
is 2120-0056. The paperwork cost associated with this proposed 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 proposed 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.

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.
