Comments We provided the public the opportunity to participate in the development of this AD. We have considered the comment received. Statement of Planned Revision to French Airworthiness Directive The commenter, the airplane manufacturer, notes that the French airworthiness directive F–2005–052 R1, dated April 13, 2005, which was cited in the NPRM, will be revised to add Airbus Modification 36115 as the final fix for the unsafe condition. The commenter notes that the purpose of Airbus Modification 36115 is to ensure that the hinge is manufactured to prevent hinge pin migration. We infer that the commenter is requesting that we consider mandating this modification when the Direction ´ ´ Generale de l’Aviation Civile (DGAC) revises French airworthiness directive F–2005–052. We will consider mandating this modification after the DGAC releases its revision. However, we will not delay issuing this AD pending release of the new French airworthiness directive and the applicable Airbus service bulletin.

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 all Boeing 
Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. That 
supplemental NPRM was published in the Federal Register on December 1, 
2005 (70 FR 72083). That supplemental NPRM proposed to require an 
inspection for chafing of certain wire bundles located above the center 
fuel tank, corrective actions if necessary, and replacement of wire 
bundle clamps with new clamps. That supplemental NPRM also proposed to 
require an inspection for damage to the fuel vapor barrier area located 
below the wire bundles and, corrective action if necessary.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. We have considered the comment received. The 
commenter supports the supplemental NPRM.

Conclusion

    We have carefully reviewed the available data, including the 
comment 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 2,871 airplanes of the affected design in the 
worldwide fleet. The following table provides the estimated costs for 
U.S. operators to comply with this AD.

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.
