14 CFR Part 39
[Docket No. FAA-2005-21860; Directorate Identifier 2005-NM-032-AD;
Amendment 39-14445; AD 2006-01-06]
RIN 2120-AA64
Airworthiness Directives; Airbus Model A330-200, A330-300, A340-
200, and A340-300 Series Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
certain Airbus Model A330-200, A330-300, A340-200, and A340-300 series
airplanes. This AD requires operators to modify the hydraulic control
block of the nose landing gear. This AD results from a report of an
unexpected steering event (swerve) during the take-off roll of one
affected airplane. We are issuing this AD to prevent loss of airplane
steering while on the ground, which could result in the airplane going
off the side of the runway.
DATES: This AD becomes effective February 10, 2006.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in the AD as of February 10,
2006.
ADDRESSES: You may examine the AD docket on the Internet at http://dms.dot.gov
or in person at the Docket Management Facility, U.S.
Department of Transportation, 400 Seventh Street, SW., Nassif Building,
room PL-401, Washington, DC.

except Federal holidays. The Docket Management Facility office
(telephone (800) 647-5227) is located on the plaza level of the Nassif
Building at the street address stated in the ADDRESSES section.
Discussion
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 to include an AD that would apply to certain Airbus Model
A330-200, A330-300, A340-200, and A340-300 series airplanes. That NPRM
was published in the Federal Register on July 19, 2005 (70 FR 41354).
That NPRM proposed to require operators to modify the hydraulic control
block of the nose landing gear.
Comments
We provided the public the opportunity to participate in the
development of this AD. We have considered the comments received.
Request To Exclude Airplanes With Certain Modification From
Applicability
The commenter requests that the applicability be revised to match
the effectivity of French airworthiness directive F-2005-016, dated
January 19, 2005. The French airworthiness directive excludes airplanes
on which Airbus Modification 50650 has been embodied in production or
Airbus Service Bulletin A330-32-3156 or A340-32-4194 has been embodied
in service. The original issue of these service bulletins, both dated
December 22, 2004, was referenced as the appropriate source of service
information for accomplishing the actions proposed in the NPRM. The
commenter states that this additional information in the applicability
would be useful for compliance with the FAA AD, particularly at the
delivery level, and would help to avoid requests for alternate methods
of compliance (AMOCs) once the AD is issued.
We partially agree with the commenter. We agree to revise the
applicability to exclude airplanes on which Airbus Modification 50650
has been embodied in production. Airplanes on which Modification 50650
has been embodied are not subject to the identified unsafe condition.
We disagree with including a reference to the service bulletins in the
applicability. Paragraph (f) of the NPRM proposed to require
accomplishing the actions in those service bulletins in order to ensure
that the actions are accomplished on all affected airplanes. In
addition, paragraph (e) of the NPRM and the final rule states, ``You
are responsible for having the actions required by this AD performed
within the compliance times specified, unless the actions have already
been done.'' If the service bulletins referenced in paragraph (f) are
accomplished then, in accordance with paragraph (e), no further actions
are necessary. Paragraph (e) accomplishes the purpose of the
commenter's request regarding airplanes on which the service bulletins
are embodied, without making an additional change to the applicability.
Therefore, we have changed the applicability of the final rule to
exclude airplanes on which Airbus Modification 50650 has been embodied
in production, but we have not added a reference to the service
bulletins in the applicability.
Request To Add Reference to Re-identified Parts
The commenter considers it useful to operators to add a new note at
the end of paragraph (f) to state that ``At the end of the
modification: The hydraulic control block (HCB) part number (P/N)
C24856000-9 will become P/N C24856000-11, and the HCB P/N C24856001-7
will become P/N C24856001-9.''
We agree with the commenter. The information about the part numbers
used for re-identifying the parts after the modification would be
useful to operators. We have not added a new note, but have included
this information in the existing Note 1 of the final rule. Note 1
refers to Messier-Bugatti Service Bulletin C24856-32-064, dated January
26, 2005, which is an additional source
[[Page 874]]
of service information for doing the modification, and which also
contains the references to the re-identified part numbers. We have also
revised paragraph (g) of the final rule to remove the statement
``unless it has been modified in accordance with paragraph (f) of this
AD.'' The modified parts have a new part number, as specified in the
revised Note 1.
Request To Add Airplanes to Applicability
The commenter requests that we add Airbus Model A330-302 and -303
airplanes to the applicability. The commenter points out that French
airworthiness directive F-2005-016, dated January 19, 2005, and Airbus
Service Bulletin A330-32-3156, dated December 22, 2004, which was
referenced as a source of service information in the NPRM, both include
these airplanes. The commenter acknowledges that Airbus Model A330-302
and -303 airplanes have not yet been certified by the FAA, but states
that the certification is expected in the near future. The commenter
suggests that, since the certification is expected and these airplane
models are included in the mandated service information, they be
included in the applicability of the final rule.
We do not agree with the commenter. AD actions are restricted to
airplanes that are type certificated for operation in the United States
under the provisions of section 21.29 of the Federal Aviation
Regulations (14 CFR 21.29) and the applicable bilateral airworthiness
agreement. However, should these airplanes be type certificated, we may
consider further AD action. We have not changed the final rule in this
regard.
Clarification of AMOC Paragraph
We have revised this action to clarify the appropriate procedure
for notifying the principal inspector before using any approved AMOC on
any airplane to which the AMOC applies.
Conclusion
We have carefully reviewed the available data, including the
comments received, and determined that air safety and the public
interest require adopting the AD with the changes described previously.
We have determined that these changes will neither increase the
economic burden on any operator nor increase the scope of the AD.
Costs of Compliance
This AD affects about 22 Model A330-200 and A330-300 airplanes of
U.S. registry. The actions take about 39 work hours per airplane, at an
average labor rate of $65 per work hour. There is no charge for
required parts. Based on these figures, the estimated cost of this AD
for U.S. operators is $55,770, or $2,535 per airplane.
There are currently no Model A340-200 or Model A340-300 airplanes
on the U.S. Register. Should one of these airplanes be imported and
placed on the U.S. Register in the future, the actions would take about
39 work hours per airplane, at an average labor rate of $65 per work
hour. Based on these figures, the estimated cost of this AD would be
$2,535 per airplane.
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 have 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 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 AD and placed it in the AD docket. See the ADDRESSES
section for a location to examine the regulatory evaluation.
