ACTION: Final rule. AGENCY: SUMMARY: The FAA is superseding an existing airworthiness directive (AD), E:\FR\FM\23MYR1.SGM 23MYR1 Federal Register / Vol. 71, No. 99 / Tuesday, May 23, 2006 / Rules and Regulations 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.

SUPPLEMENTARY INFORMATION: dsatterwhite on PROD1PC76 with RULES ADDRESSES: VerDate Aug<31>2005 19:30 May 22, 2006 Jkt 208001 Examining the Docket You may examine the airworthiness directive (AD) docket on the Internet at https://dms.dot.gov or in person at the Docket Management Facility office between 9 a.m. and 5 p.m., Monday through Friday, 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 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 onetime 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 PO 00000 Frm 00017 Fmt 4700 Sfmt 4700 29581 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. E:\FR\FM\23MYR1.SGM 23MYR1 29582 Federal Register / Vol. 71, No. 99 / Tuesday, May 23, 2006 / Rules and Regulations 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. dsatterwhite on PROD1PC76 with RULES 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 VerDate Aug<31>2005 19:30 May 22, 2006 Jkt 208001 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.

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.

SUPPLEMENTARY INFORMATION:

Examining the Docket

    You may examine the airworthiness directive (AD) docket on the 
Internet at https://dms.dot.gov or in person at the Docket Management 
Facility office between 9 a.m. and 5 p.m., Monday through Friday, 
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 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.

this AD, Revision 02 of the service bulletin must be used for 
accomplishing the modification. Accomplishing this modification ends 
the repetitive inspections required by paragraph (g) of this AD.

New Requirements of This AD

One-Time Inspection/Replacement if Necessary

    (j) For airplanes on which Airbus Service Bulletin A300-28-6069, 
dated September 4, 2001; or Revision 01, dated May 28, 2002, has 
been accomplished before the effective date of this AD: Within 18 
months after the effective date of this AD, perform a one-time 
detailed 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 replace the bolts as 
applicable, by doing all the actions in accordance with paragraphs
