Airworthiness Directives; Airbus Airplanes

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

ACTION: Final rule; request for comments.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for all 
Airbus Model A330-201, -202, -203, -301, -302, and -303 airplanes. This 
AD requires a one-time ultrasonic inspection for fractures of all aft 
mount-pylon bolts of each engine. This AD was prompted by a report of 
one bolt on the aft engine mount upper beam found totally broken. We 
are issuing this AD to detect and correct fracture of the aft mount-
pylon bolts, which could result in failure of the engine mount and 
consequent detachment of the engine.

DATES: This AD becomes effective February 17, 2015.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of February 17, 
2015.

SUPPLEMENTARY INFORMATION:

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 2013-0094, dated April 15, 2013 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for certain Airbus Model 
A330-201, -202, -203, -301, -302, and -303 airplanes. The MCAI states:

    During a scheduled replacement of a CF6-80E1 engine #1 on an 
A330 aeroplane, one bolt on the aft engine mount upper beam was 
found totally broken. That bolt is one of the four bolts that attach 
the upper beam to the pylon.
    The subsequent analyses of the broken bolt and the upper beam 
identified the following:

--a fatigue origin area with crack propagation from the boundary of 
the bolt,
--a spiral groove with cold work and microstructural distortion 
underlying that extended axially along the shank, and
--a score mark on counter-bore edge of the upper beam.

    The preliminary root-cause investigation shows that an unusual 
contact with the counter-bore edge of the beam induced a significant 
groove on the bolt during its installation in production. It is 
suspected that this groove led to a fatigue crack initiation and 
subsequent quick propagation leading to the complete fracture of the 
bolt.
    As the root-cause is still under investigation, including the 
installation sequence specific to this aeroplane--engine model, the 
other A330 propulsion systems are not affected.
    This condition, if not detected and corrected, could lead, in 
conjunction with a second fractured bolt, to the loss of engine 
mount structural integrity and potential engine detachment in flight 
as the remaining bolts would not be able to sustain the residual 
fatigue and limit loads.
    For the reasons described above, this [EASA] AD requires a one-
time ultrasonic inspection of the four aft mount-pylon bolts of both 
engines for detection of completely sheared [fractured] bolts 
through the bolt section and, depending on finding, accomplishment 
of applicable corrective actions [repair].
    This [EASA] AD is considered as an interim action, pending the 
results of the ongoing investigations, and further AD action may 
follow.

You may examine the MCAI on the Internet at http://www.regulations.gov 
by searching for and locating Docket No. FAA-2015-0079.

Related Service Information

    Airbus has issued Alert Operators Transmission (AOT) A71L002-13, 
dated April 8, 2013. The service information describes procedures to 
perform a one-time ultrasonic inspection for fractures of all aft 
mount-pylon bolts of each engine. The actions described in this service 
information are intended to correct the unsafe condition identified in 
the MCAI.

FAA's Determination and Requirements of This 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 issuing this AD because we 
evaluated all pertinent information and determined the unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.

FAA's Determination of the Effective Date

    Since there are currently no domestic operators of this product, 
notice and opportunity for public comment before issuing this AD are 
unnecessary.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and we did not precede it by notice and opportunity for public 
comment. We invite you to send any written relevant data, views, or 
arguments about this AD. Send your comments to an address listed under 
the ADDRESSES section. Include ``Docket No. FAA-2015-0079; Directorate 
Identifier 2013-NM-091-AD'' at the beginning of your comments. We 
specifically invite comments on the overall regulatory, economic, 
environmental, and energy aspects of this AD. We will consider all 
comments received by the closing date and may amend this AD based on 
those comments.
    We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this AD.

Costs of Compliance

    We estimate that this AD affects 0 airplanes of U.S. registry.
    We also estimate that it will take about 3 work-hours per product 
to comply with the basic requirements of this AD. The average labor 
rate is $85 per work-hour. Based on these figures, we estimate the cost 
of this AD on U.S. operators to be $255 per product.
    We have received no definitive data that would enable us to provide 
cost estimates for the on-condition action specified in this AD. We 
have no way of determining the number of aircraft that might need this 
action.

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 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.

[[Page 5022]]

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.

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.
