Series Airplanes, and A310 Series Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: We propose to adopt a new airworthiness directive (AD) for the
products listed above. This proposed AD results from mandatory
continuing airworthiness information (MCAI) originated by an aviation
authority of another country to identify and correct an unsafe
condition on an aviation product. The MCAI describes the unsafe
condition as: During a maintenance check performed by an A310 operator,
the recommended modification of the lower attachment beam of rack 101VU
by accomplishment of Airbus Service Bulletin (SB) A310-53-2076 was
embodied on the aeroplane, leading the operator to find three cracks on
the FR15A crossbeam above the NLG [nose landing gear] box at the
splicing with rack 107VU fitting. This condition, if not detected and
corrected, could degrade the structural integrity of the crossbeam on
NLG FR15A web attachment fitting of rack 107VU. Rack 107VU contains
major airworthiness system components whose functioning could be
adversely affected by the loss of the attachment fitting. As the A300
and A300-600 aeroplanes share this design feature, they are also
affected. The proposed AD would require actions that are intended to
address the unsafe condition described in the MCAI.

Discussion
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Community, has issued EASA
Airworthiness Directive 2009-0165, dated July 31, 2009 (referred to
after this as ``the MCAI''), to correct an unsafe condition for the
specified products. The MCAI states:
During a maintenance check performed by an A310 operator, the
recommended modification of the lower attachment beam of rack 101VU
by accomplishment of Airbus Service Bulletin (SB) A310-53-2076 was
embodied on the aeroplane, leading the operator to find three cracks
on the FR15A crossbeam above the NLG [nose landing gear] box at the
splicing with rack 107VU fitting.
This condition, if not detected and corrected, could degrade the
structural integrity of the crossbeam on NLG FR15A web attachment
fitting of rack 107VU. Rack 107VU contains major airworthiness
system components whose functioning could be adversely affected by
the loss of the attachment fitting.
As the A300 and A300-600 aeroplanes share this design feature,
they are also affected.
[[Page 8550]]
For the reasons stated above, this AD requires repetitive
inspections for cracks of the crossbeam on NLG FR15A web face
attachment fitting of rack 107VU and corrective action, depending on
findings.
The corrective actions include contacting Airbus for repair
instructions, and doing the repair if any crack is found. You may
obtain further information by examining the MCAI in the AD docket.
Relevant Service Information
Airbus has issued the following service bulletins:
Airbus Mandatory Service Bulletin A300-53-0388, including
Appendix 01, dated March 17, 2009;
Airbus Mandatory Service Bulletin A300-53-6164, including
Appendix 01, dated March 17, 2009; and
Airbus Mandatory Service Bulletin A310-53-2131, including
Appendix 01, dated March 17, 2009.
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 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 the same
type design.
Differences Between This AD and the MCAI or Service Information
We have reviewed the MCAI and related service information and, in
general, agree with their substance. But we might have found it
necessary to use different words from those in the MCAI to ensure the
AD is clear for U.S. operators and is enforceable. In making these
changes, we do not intend to differ substantively from the information
provided in the MCAI and related service information.
We might also have proposed different actions in this AD from those
in the MCAI in order to follow FAA policies. Any such differences are
highlighted in a NOTE within the proposed AD.
Costs of Compliance
Based on the service information, we estimate that this proposed AD
would affect about 206 products of U.S. registry. We also estimate that
it would take about 2 work-hours per product to comply with the basic
requirements of this proposed AD. The average labor rate is $85 per
work-hour. Based on these figures, we estimate the cost of the proposed
AD on U.S. operators to be $35,020, or $170 per product, per inspection
cycle.
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); and
3. 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.
We prepared a regulatory evaluation of the estimated costs to
comply with this proposed AD and placed it in the AD docket.

certificated in any category.
Subject
(d) Air Transport Association (ATA) of America Code 53:
Fuselage.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
During a maintenance check performed by an A310 operator, the
recommended modification of the lower attachment beam of rack 101VU
by accomplishment of Airbus Service Bulletin (SB) A310-53-2076 was
embodied on the aeroplane, leading the operator to find three cracks
on the FR15A crossbeam above the NLG [nose landing gear] box at the
splicing with rack 107VU fitting.
This condition, if not detected and corrected, could degrade the
structural integrity of the crossbeam on NLG FR15A web attachment
fitting of rack 107VU. Rack 107VU contains major airworthiness
system components whose functioning could be adversely affected by
the loss of the attachment fitting.
As the A300 and A300-600 aeroplanes share this design feature,
they are also affected.
For the reasons stated above, this AD requires repetitive
inspections for cracks of the crossbeam on NLG FR15A web face
attachment fitting of rack 107VU and corrective action, depending on
findings.
The corrective actions include contacting Airbus for repair
instructions, and doing the repair if any crack is found.
Compliance
(f) You are responsible for having the actions required by this
AD performed within
[[Page 8551]]
the compliance times specified, unless the actions have already been
done.
