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 all 
Airbus Model A330-200, A330-200 Freighter, A330-300, A340-500, and 
A340-600 series airplanes; and A340-313 airplanes. This proposed AD was 
prompted by the discovery of Tartaric Sulfuric Anodizing (TSA)/Chromic 
Acid

[[Page 95539]]

Anodizing (CAA) surface treatment in certain bulk cargo door frame 
holes of certain airplanes. This proposed AD would require inspection 
of the fuselage bulk cargo door frames at specific locations, and

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 2016-0102, dated June 1, 2016; corrected June 
7, 2016 (referred to after this as the Mandatory Continuing 
Airworthiness Information, or ``the MCAI''); to correct an unsafe 
condition for all Airbus Model A330-200, A330-200 Freighter, A330-300, 
A340-500, and A340-600 series airplanes; and A340-313 airplanes. The 
MCAI states:

    In the frame of the certification of the A330 Extended Service 
Goal exercise, it has been identified that Tartaric Sulfuric 
Anodising (TSA)/Chromic Acid Anodising (CAA) surface treatment is 
present in some frame holes, from aeroplane MSN 0400 and later MSN, 
following production process modification. On bulk cargo door frames 
(FR) 67 and FR 69 Right Hand Side, the door fitting attachment holes 
have this TSA/CAA treatment, which leads to a detrimental effect on 
fatigue behaviour. This condition, if not detected and corrected, 
could lead to critical cracks in the primary structure, possibly 
resulting in in-flight loss of a bulk cargo door, consequent 
decompression and potential damage to the aeroplane that could 
reduce the control of the aeroplane.
    To address this potential unsafe condition, Airbus issued Alert 
Operators Transmission (AOT) A53L012-16 to provide instructions to 
inspect the fuselage bulk cargo door frames at specific locations.
    For the reasons described above, this [EASA] AD requires 
repetitive non-destructive test (rototest and high-frequency eddy-
current (HFEC)) inspection or visual detailed (DET) inspections [to 
detect cracking] of the affected areas, and, depending on findings, 
accomplishment of a repair.
    This [EASA] AD is considered an interim measure, and further 
[EASA] AD action may follow.

    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-
9517.

Related Service Information Under 1 CFR Part 51

    We reviewed Airbus Alert Operators Transmission (AOT), AOT A53L012-
16, Revision 00, including Appendices 1 through 6, dated May 30, 2016:

Door-Fittings FR67 at STGR 37 and at STGR 42 and FR 69 at STRG 38 and 
at STGR 45,'' advanced copy approved for use, dated May 18, 2016.
    The service information describes procedures for inspections of the 
fuselage bulk cargo frames at the door support and latch fittings 
location; repair instructions; and reporting instructions. 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.

[[Page 95540]]

Costs of Compliance

    We estimate that this proposed AD affects 96 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                                 Cost on U.S.

    We estimate the following costs to do any necessary replacements 
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 
this replacement:

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.

List of Subjects in 14 CFR Part 39
