SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to include an airworthiness directive (AD) that would apply to 
all Boeing Model 727 airplanes. That NPRM was published in the Federal 
Register on August 8, 2007 (72 FR 44433). That NPRM proposed to require 
repetitive external high frequency eddy current (HFEC) inspections of 
the crown skin for cracks at certain stringer attachment holes, and 
repair if necessary.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We considered the comment received from the commenter.

Request to Delegate Approval of Alternative Methods of Compliance 
(AMOC) for Repairs

    Boeing requests that paragraph (h) of the NPRM be revised to allow 
AMOCs for any required repair to be approved by an Authorized 
Representative for the Boeing Commercial Airplanes Delegation Option 
Authorization Organization who has been authorized by the Manager, 
Seattle Aircraft Certification Office.
    We agree with Boeing's request and have revised paragraph (h) of 
the AD accordingly.

Conclusion

    We reviewed the relevant data, considered the comment received, and 
determined that air safety and the public interest require adopting the 
AD with the change described previously. We also determined that this 
change will not increase the economic burden

[[Page 4054]]

on any operator or increase the scope of the AD.

Costs of Compliance

    There are about 842 airplanes of the affected design in the 
worldwide fleet. This AD affects about 459 airplanes of U.S. registry. 
The inspection takes about 110 work hours per airplane, at an average 
labor rate of $80 per work hour. Based on these figures, the estimated 
cost of the AD for U.S. operators is $4,039,200, or $8,800 per 
airplane, per inspection cycle.

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

    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.
    You can find our regulatory evaluation and the estimated costs of 
compliance in the AD Docket.

Alternative Methods of Compliance (AMOCs)

    (h)(1) The Manager, Seattle Aircraft Certification Office (ACO), 
FAA, has the authority to approve AMOCs for this AD, if requested in 
accordance with the procedures found in 14 CFR 39.19.
    (2) To request a different method of compliance or a different

Flight Standards District Office (FSDO), or lacking a PI, your local 
FSDO.
    (3) An AMOC that provides an acceptable level of safety may be 
used for any repair required by this AD, if it is approved by an 
Authorized Representative for the Boeing Commercial Airplanes 
Delegation Option Authorization Organization who has been authorized

method to be approved, the repair must meet the certification basis 
of the airplane, and the approval must specifically refer to this 
AD.
