ACTION: Final rule. AGENCY: sroberts on PROD1PC70 with RULES Revision level SUMMARY: The FAA is superseding an existing airworthiness directive (AD), which applies to certain Airbus Model A300 B4–600 and A300 C4–600 series airplanes. That AD currently requires a one-time inspection to detect damage of the pump diffuser guide slots (bayonet) of the center tank fuel pumps, the pump diffuser housings, and the pump canisters; repetitive inspections to detect damage of the fuel pumps and the fuel pump canisters; and corrective action, if necessary. This new AD adds, VerDate Aug<31>2005 19:09 Jun 06, 2006 Jkt 208001 for new airplanes, repetitive inspections of the pump bodies for cracking, damage, and missing and broken fasteners; repetitive inspections of the fuel pump canisters for a cracked flange web; and corrective actions if necessary. For all airplanes, this new AD also adds replacement of the fuel pump canisters with new reinforced fuel pump canisters, which ends the repetitive inspections. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to detect and correct damage of the center tank fuel pumps and fuel pump canisters, which could result in separation of a pump from its electrical motor housing, loss of flame trap capability, and a possible fuel ignition source in the center fuel tank. DATES: This AD becomes effective July 12, 2006. The Director of the Federal Register approved the incorporation by reference of certain publications listed in the AD as of July 12, 2006. On May 19, 2004 (69 FR 19756, April 14, 2004), the Director of the Federal Register approved the incorporation by reference of Airbus All Operators Telex A300–600–28A6075, dated February 20, 2003.

SUPPLEMENTARY INFORMATION: Examining the Docket You may examine the airworthiness directive (AD) docket on the Internet at http://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 2004–08–03, amendment 39–13572 (69 FR 19756, April 14, 2004). The existing AD applies to certain Airbus Model A300 B4–600 and A300 C4–600 series airplanes. That NPRM was published in the Federal Register on March 27, 2006 (71 FR 15079). That NPRM proposed to require a one-time inspection to detect damage of the pump diffuser guide slots (bayonet) of the center tank fuel pumps, the pump diffuser housings, and the pump canisters; repetitive inspections to detect damage of the fuel pumps and the fuel pump canisters; and corrective action, if necessary. That NPRM proposed to add, for new airplanes, repetitive inspections of the pump E:\FR\FM\07JNR1.SGM 07JNR1 32816 Federal Register / Vol. 71, No. 109 / Wednesday, June 7, 2006 / Rules and Regulations bodies for cracking, damage, and missing and broken fasteners; repetitive inspections of the fuel pump canisters for a cracked flange web; and corrective actions if necessary. For all airplanes, that NPRM also proposed to add replacement of the fuel pump canisters with new reinforced fuel pump canisters, which ends the repetitive inspections. Comments We provided the public the opportunity to participate in the development of this AD. No comments have been received on the NPRM or on the determination of the cost to the public. Conclusion We have carefully reviewed the available data and determined that air safety and the public interest require adopting the AD as proposed. Costs of Compliance This AD will affect about 74 airplanes of U.S. registry. The following table provides the estimated costs, at an average labor rate of $80 per hour, for U.S. operators to comply with this AD.

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. sroberts on PROD1PC70 with RULES 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, VerDate Aug<31>2005 19:09 Jun 06, 2006 Jkt 208001 Parts Number U.S.-registered airplanes Airbus Model— Cost per airplane 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.

ACTION: SUMMARY: The FAA is adopting a new airworthiness directive (AD) for certain 747–100B, 747–200B, 747–200F, 747– 300, 747–400, 747–400F, and 747SP series airplanes. This AD requires doing inspections of the midpivot bolt and midpivot bolt access door of the spring beam of the inboard side of the outboard struts for discrepancies, installing a placard on the midpivot bolt access door, and applicable corrective actions if necessary. This AD results from reports indicating that the midpivot bolt and midpivot bolt access door of the spring beam of the inboard side of the outboard struts were installed in the incorrect position. We are issuing this AD to ensure that the subject midpivot bolts and midpivot bolt access doors are installed in the correct position. If not installed in the correct position, a midpivot bolt could be overloaded and crack or fracture, which could result in the loss of the spring load path and consequent separation of the associated E:\FR\FM\07JNR1.SGM 07JNR1

Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The FAA is superseding an existing airworthiness directive 
(AD), which applies to certain Airbus Model A300 B4-600 and A300 C4-600 
series airplanes. That AD currently requires a one-time inspection to 
detect damage of the pump diffuser guide slots (bayonet) of the center 
tank fuel pumps, the pump diffuser housings, and the pump canisters; 
repetitive inspections to detect damage of the fuel pumps and the fuel 
pump canisters; and corrective action, if necessary. This new AD adds, 
for new airplanes, repetitive inspections of the pump bodies for 
cracking, damage, and missing and broken fasteners; repetitive 
inspections of the fuel pump canisters for a cracked flange web; and 
corrective actions if necessary. For all airplanes, this new AD also 
adds replacement of the fuel pump canisters with new reinforced fuel 
pump canisters, which ends the repetitive inspections. This AD results 
from fuel system reviews conducted by the manufacturer. We are issuing 
this AD to detect and correct damage of the center tank fuel pumps and 
fuel pump canisters, which could result in separation of a pump from 
its electrical motor housing, loss of flame trap capability, and a 
possible fuel ignition source in the center fuel tank.

DATES: This AD becomes effective July 12, 2006.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of July 12, 2006.
    On May 19, 2004 (69 FR 19756, April 14, 2004), the Director of the 
Federal Register approved the incorporation by reference of Airbus All 
Operators Telex A300-600-28A6075, dated February 20, 2003.

SUPPLEMENTARY INFORMATION:

Examining the Docket

    You may examine the airworthiness directive (AD) docket on the 
Internet at http://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 2004-08-03, amendment 
39-13572 (69 FR 19756, April 14, 2004). The existing AD applies to 
certain Airbus Model A300 B4-600 and A300 C4-600 series airplanes. That 
NPRM was published in the Federal Register on March 27, 2006 (71 FR 
15079). That NPRM proposed to require a one-time inspection to detect 
damage of the pump diffuser guide slots (bayonet) of the center tank 
fuel pumps, the pump diffuser housings, and the pump canisters; 
repetitive inspections to detect damage of the fuel pumps and the fuel 
pump canisters; and corrective action, if necessary. That NPRM proposed 
to add, for new airplanes, repetitive inspections of the pump

[[Page 32816]]

bodies for cracking, damage, and missing and broken fasteners; 
repetitive inspections of the fuel pump canisters for a cracked flange 
web; and corrective actions if necessary. For all airplanes, that NPRM 
also proposed to add replacement of the fuel pump canisters with new 
reinforced fuel pump canisters, which ends the repetitive inspections.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. No comments have been received on the NPRM or 
on the determination of the cost to the public.

Conclusion

    We have carefully reviewed the available data and determined that 
air safety and the public interest require adopting the AD as proposed.

Costs of Compliance

    This AD will affect about 74 airplanes of U.S. registry. The 
following table provides the estimated costs, at an average labor rate 
of $80 per hour, for U.S. operators to comply with this AD.

runAuthority 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.
