14 CFR Part 39
[Docket No. 2003-NM-16-AD; Amendment 39-13970; AD 2005-03-14]
RIN 2120-AA64
Airworthiness Directives; Airbus Model A300 B2 and B4 Series
Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This amendment supersedes an existing airworthiness directive
(AD) that applies to all Airbus Model A300 B2 and B4 series airplanes.
The existing AD currently requires determining the part and amendment
number of the variable lever arm (VLA) of the rudder control system to
verify the parts were installed using the correct standard, and
corrective actions if necessary. For certain VLAs, this new AD requires
repetitive inspections of the VLA and corrective action if necessary.
This new AD also provides a terminating action for the repetitive
inspections. Furthermore, this new AD reduces the applicability of
affected airplanes. The actions specified by this AD are intended to
prevent failure of both spring boxes of certain VLAs due to corrosion
damage, which could result in loss of rudder control and consequent
reduced controllability of the airplane. This action is intended to
address the identified unsafe condition.
DATES: Effective March 21, 2005.
The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of March 21, 2005.
The incorporation by reference of a certain other publication as
listed in the regulations was approved previously by the Director of
the Federal Register as of November 13, 2001 (66 FR 54416, October 29,
2001).
ADDRESSES: The service information referenced in this AD may be
obtained from Airbus, 1 Rond Point Maurice Bellonte, 31707 Blagnac
Cedex, France. This information may be examined at the Federal Aviation
Administration (FAA), Transport Airplane Directorate, Rules Docket,

FOR FURTHER INFORMATION CONTACT: Tim Backman, Aerospace Engineer,
International Branch, ANM-116, FAA, Transport Airplane Directorate,
1601 Lind Avenue, SW., Renton, Washington 98055-4056; telephone (425)
227-2797; fax (425) 227-1149.
SUPPLEMENTARY INFORMATION: The FAA proposed to amend part 39 of the
Federal Aviation Regulations (14 CFR part 39) with an AD to supersede
AD 2001-22-02, amendment 39-12481 (66 FR 54416, October 29, 2001). The
existing AD applies to all Airbus Model A300 B2 and B4 series
airplanes. The proposed AD was published as a supplemental notice of
proposed
[[Page 7385]]
rulemaking (NPRM) in the Federal Register on October 5, 2004 (69 FR
59557). The supplemental NPRM proposed to continue to require
determining the part and amendment number of the variable lever arm
(VLA) of the rudder control system to verify the parts were installed
using the correct standard, and corrective actions if necessary. The
supplemental NPRM also proposed to require repetitive inspections for
damage, and replacement with a new VLA if necessary. The supplemental
NPRM also proposed to reduce the applicability of affected airplanes
and to mandate a terminating modification of the VLA, which would end
the repetitive inspections.
Comments
Interested persons have been afforded an opportunity to participate
in the making of this amendment. Due consideration has been given to
the comment received.
Request To Clarify Affected Part Numbers
The commenter requests that paragraph (b) of the proposed AD be
revised to specify that the referenced part numbers are for VLA spring
boxes. The commenter states that the supplemental NPRM gives the
impression of addressing a VLA assembly with P/Ns other than 418473-20
or 418473-200. The commenter notes that the referenced P/Ns are
actually for the VLA spring boxes, not the VLA assembly. The P/Ns of
the VLA assemblies are ``40720 with amendments other than 6,'' as
described in Airbus Service Bulletin A300-27-0196, Revision 01, dated
November 13, 2002 (which was referenced in the supplemental NPRM as the
appropriate source of service information for accomplishment of the
inspections and corrective actions). The commenter contends that unless
the P/Ns are clearly identified, operators may be confused regarding
the applicability of paragraph (b) of the supplemental NPRM.
We agree with the commenter's request to clarify the affected part
numbers. Paragraph (b) of this AD has been revised accordingly.
Conclusion
After careful review of the available data, including the comment
noted above, we have determined that air safety and the public interest
require the adoption of the rule with the change described previously.
We have determined that this change will neither increase the economic
burden on any operator nor increase the scope of the AD.
Cost Impact
About 33 airplanes of U.S. registry will be affected by this AD.
The actions that are currently required by AD 2001-22-02, and
retained in this AD, take about 1 work hour per airplane to accomplish,
at an average labor rate of $65 per work hour. Based on these figures,
the cost impact of the currently required actions on U.S. operators is
estimated to be $65 per airplane.
The new inspection required by this AD will take about 1 work hour
per airplane to accomplish, at an average labor rate of $65 per work
hour. Based on these figures, the cost impact of the new inspections on
U.S. operators is estimated to be $2,145, or $65 per airplane, per
inspection cycle.
The new modification required by this AD will take about 4 hours
per airplane to accomplish, at an average labor rate of $65 per work
hour. Required parts cost will be minimal. Based on these figures, the
cost impact of the new modification on U.S. operators is $8,580, or
$260 per airplane.
The cost impact figures discussed above are based on assumptions
that no operator has yet accomplished any of the requirements of this
AD action, and that no operator would accomplish those actions in the
future if this AD were not adopted. The cost impact figures discussed
in AD rulemaking actions represent only the time necessary to perform
the specific actions actually required by the AD. These figures
typically do not include incidental costs, such as the time required to
gain access and close up, planning time, or time necessitated by other
administrative actions.
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 Impact
The regulations adopted herein 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. Therefore, it
is determined that this final rule does not have federalism
implications under Executive Order 13132.
For the reasons discussed above, I certify that this action (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. A final evaluation has been prepared for this action
and it is contained in the Rules Docket. A copy of it may be obtained
from the Rules Docket at the location provided under the caption
