Airworthiness Directives; Airbus Model A300 B4-600R and A300 F4-
600R Series Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is superseding an existing airworthiness directive
(AD),
[[Page 29581]]
which applies to certain Airbus Model A300 B4-600R and A300 F4-600R
series airplanes. That AD currently requires repetitive inspections for
damage of the center tank fuel pumps and fuel pump canisters and
replacement of any damaged parts, and mandates modification of the
canisters of the center tank fuel pumps, which terminates the
repetitive inspections. For certain airplanes, this new AD requires a
one-time inspection of the attachment bolts of the outlet flange of the
canisters of the center tank fuel pumps for bolts that are too short
and do not protrude through the nut, and replacement of the bolts if
necessary. This AD results from several reports that the attachment
bolts for the canisters, modified by the requirements in the existing
AD, are too short and do not fully protrude from the nuts. We are
issuing this AD to prevent damage to the fuel pump and fuel pump
canister, which could result in loss of flame trap capability and could
provide a fuel ignition source in the center fuel tank.
DATES: This AD becomes effective June 27, 2006.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in the AD as of June 27, 2006.
On December 20, 2004 (69 FR 65528, November 15, 2004), the Director
of the Federal Register approved the incorporation by reference of
certain publications.
On February 8, 2000 (65 FR 213, January 4, 2000), the Director of
the Federal Register approved the incorporation by reference of a
certain publication.
On December 28, 1998 (63 FR 70639, December 22, 1998), the Director
of the Federal Register approved the incorporation by reference of a
certain publication.

Discussion
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 to include an AD that supersedes AD 2004-23-08, amendment
39-13863 (69 FR 65528, November 15, 2004). The existing AD applies to
certain Airbus Model A300 B4-600R and A300 F4-600R series airplanes.
That NPRM was published in the Federal Register on February 2, 2006 (71
FR 5620). That NPRM proposed to continue to require repetitive
inspections for damage of the center tank fuel pumps and fuel pump
canisters and replacement of any damaged parts, and modification of the
canisters of the center tank fuel pumps, which terminates the
repetitive inspections. For certain airplanes, that NPRM also proposed
to require a one-time inspection of the attachment bolts of the outlet
flange of the canisters of the center tank fuel pumps for bolts that
are too short and do not protrude through the nut, and replacement of
the bolts if necessary.
Comments
We provided the public the opportunity to participate in the
development of this AD. We have considered the comments that have been
received on the NPRM.
Request for Exemption From New Actions
Airbus asks that we include a note that specifies that airplanes on
which Airbus Service Bulletin A300-28-6069, Revision 02, dated October
17, 2003, has been accomplished previously are exempt from the new
requirements in the NPRM.
American Airlines (AA) states that paragraph (j) of the NPRM does
not specifically reference Service Bulletin A300-28-6069, Revision 02;
therefore, AA concludes that airplanes modified per Revision 02 are
excluded from the NPRM because they would have been modified by
incorporating the correct length bolt. AA adds that paragraph (j)
instructs operators to do all the actions in accordance with paragraphs
3.A., 3.B., 3.C., 3.D., and 3.E. of the Accomplishment Instructions of
Airbus Service Bulletin A300-28-6087, dated April 8, 2005. AA notes
that Service Bulletin A300-28-6087 specifies that if the additional
work in Service Bulletin A300-28-6069, Revision 02, has been
accomplished, the actions specified in Service Bulletin A300-28-6087
are not applicable. AA states that this conclusion may not be readily
apparent to all operators and should be clarified.
We agree with the above comments. We have included a note which
specifies that airplanes modified in accordance with Service Bulletin
A300-28-6069, Revision 02, are not subject to the requirements of
paragraph (j) of this AD.
Request for Increased Administrative Responsiveness
AA provided comments on its perception of the lack of
administrative responsiveness to relevant emerging service information
affecting regulatory actions. AA states that AD 2004-23-08, amendment
39-13863 (69 FR 65528, November 15, 2004), issued on November 15, 2004,
is an example of where relevant information to the regulatory actions
was published prior to the release of the subject NPRM. AA adds that
the unsafe condition addressed in this NPRM supersedure was first
published in Airbus Service Bulletin A300-28-6069, Revision 02, dated
October 17, 2003, which was issued 13 months prior to the release of AD
2004-23-08 (the AD that was superseded). AA notes that sufficient
awareness during that time should have allowed both unsafe conditions
to be addressed concurrently in the NPRM.
Although AA did not submit a specific request, we acknowledge their
comments. We make every effort to streamline our rulemaking process and
ensure that a complete and up-to-date rulemaking package is issued.
While the condition was addressed in an earlier service bulletin, the
corresponding DGAC airworthiness directive was not published until
after we issued AD 2004-23-08. At that time we discovered that an
unsafe condition existed related to the actions required by that AD. We
are responsible for ensuring the continued airworthiness of U.S. type
certificated and U.S-registered airplanes. Thus, we determined it was
necessary to address the identified unsafe condition. This AD is
intended to address that unsafe condition, and we find no change to
this AD is possible with regard to the commenter's statements.
[[Page 29582]]
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 as proposed.
Costs of Compliance
This AD affects about 101 airplanes of U.S. registry.
The inspections that are required by AD 2004-23-08, and retained in
this AD, take about 2 work hours per airplane, at an average labor rate
of $65 per work hour. Based on these figures, the estimated cost of the
currently required inspections is $130 per airplane, per inspection
cycle.
The modification that is required by AD 2004-23-08, and retained in
this AD, takes about 2 work hours per airplane, at an average labor
rate of $65 per work hour. Required parts will cost about $9,620 per
airplane. Based on these figures, the estimated cost of the currently
required modification is $9,750 per airplane.
The new one-time inspection takes about 1 work hour per airplane,
at an average labor rate of $65 per work hour. Based on these figures,
the estimated cost of the new inspection specified in this AD for U.S.
operators is $6,565 or $65 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.
