ACTION: Final rule. AGENCY: SUMMARY: The FAA is adopting a new airworthiness directive (AD) for certain E:\FR\FM\09SER1.SGM 09SER1 Federal Register / Vol. 70, No. 174 / Friday, September 9, 2005 / Rules and Regulations Boeing Model 757 airplanes. This AD requires inspections of certain wire bundles in the left and right engine-towing aft fairings for discrepancies; installation of back-to-back p-clamps between the wire and hydraulic supply tube at the aft end of the right-hand strut only; and associated re-routing of the wire bundles, if necessary. This AD results from a report indicating that a circuit breaker for the fuel shutoff valve tripped due to a wire that chafed against the structure in the flammable leakage zone of the aft fairing, causing a short circuit. We are issuing this AD to prevent chafing between the wire bundle and the structure of the aft fairing, which could result in electrical arcing and subsequent ignition of flammable vapors and possible uncontrollable fire.

SUPPLEMENTARY INFORMATION: Examining the Docket You may examine the 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 supplemental notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to certain Boeing Model 757 airplanes. That supplemental NPRM was published in the Federal Register on July 6, 2005 (70 FR 38823). That supplemental NPRM proposed to VerDate Aug<18>2005 15:11 Sep 08, 2005 Jkt 205001 require inspections of certain wire bundles in the left and right engine-towing aft fairings for discrepancies; installation of back-to-back p-clamps between the wire and hydraulic supply tube at the aft end of the right-hand strut only; and associated re-routing of the wire bundles, if necessary. Comments We provided the public the opportunity to participate in the development of this AD. We have considered the comments received. The commenters support the supplemental NPRM. 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 in the supplemental NPRM. Costs of Compliance There are about 618 airplanes of the affected design in the worldwide fleet. This AD will affect about 342 airplanes of U.S. registry. The actions will take between 16 and 44 work hours per airplane, depending on airplane configuration, at an average labor rate of $65 per work hour. Required parts will cost about $600 per airplane. Based on these figures, the estimated cost of this AD on U.S. operators is between $560,880 and $1,183,320, or between $1,640 and $3,460 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 PO 00000 Frm 00019 Fmt 4700 Sfmt 4700 53555 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.

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain

[[Page 53555]]

Boeing Model 757 airplanes. This AD requires inspections of certain 
wire bundles in the left and right engine-to-wing aft fairings for 
discrepancies; installation of back-to-back p-clamps between the wire 
and hydraulic supply tube at the aft end of the right-hand strut only; 
and associated re-routing of the wire bundles, if necessary. This AD 
results from a report indicating that a circuit breaker for the fuel 
shutoff valve tripped due to a wire that chafed against the structure 
in the flammable leakage zone of the aft fairing, causing a short 
circuit. We are issuing this AD to prevent chafing between the wire 
bundle and the structure of the aft fairing, which could result in 
electrical arcing and subsequent ignition of flammable vapors and 
possible uncontrollable fire.

SUPPLEMENTARY INFORMATION:

Examining the Docket

    You may examine the 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

plaza level of the Nassif Building at the street address stated in the 
ADDRESSES section.

Discussion

    The FAA issued a supplemental notice of proposed rulemaking (NPRM) 
to amend 14 CFR part 39 to include an AD that would apply to certain 
Boeing Model 757 airplanes. That supplemental NPRM was published in the 
Federal Register on July 6, 2005 (70 FR 38823). That supplemental NPRM 
proposed to require inspections of certain wire bundles in the left and 
right engine-to-wing aft fairings for discrepancies; installation of 
back-to-back p-clamps between the wire and hydraulic supply tube at the 
aft end of the right-hand strut only; and associated re-routing of the 
wire bundles, if necessary.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. We have considered the comments received. The 
commenters support the supplemental NPRM.

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 in the supplemental NPRM.

Costs of Compliance

    There are about 618 airplanes of the affected design in the 
worldwide fleet. This AD will affect about 342 airplanes of U.S. 
registry. The actions will take between 16 and 44 work hours per 
airplane, depending on airplane configuration, at an average labor rate 
of $65 per work hour. Required parts will cost about $600 per airplane. 
Based on these figures, the estimated cost of this AD on U.S. operators 
is between $560,880 and $1,183,320, or between $1,640 and $3,460 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.
