SUPPLEMENTARY INFORMATION: Discussion The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would E:\FR\FM\17DER1.SGM 17DER1 Federal Register / Vol. 72, No. 241 / Monday, December 17, 2007 / Rules and Regulations apply to certain Boeing Model 747– 200C and –200F series airplanes. That NPRM was published in the Federal Register on August 16, 2007 (72 FR 45954). That NPRM proposed to require, among other actions, installing mounting brackets, support angles, and moisture curtains in the main equipment center. Comments We provided the public the opportunity to participate in the development of this AD. We have considered the comment received. Request To Refer to Earlier Revision of a Referenced Service Bulletin Boeing requests that paragraph (g) of the NPRM be revised to include Boeing Alert Service Bulletin 747–38A2073, Revision 1, dated June 21, 1990; and Revision 2, dated April 26, 2001; as additional sources of service information for accomplishing the prior or concurrent requirements. Boeing states that this will align the NPRM with Boeing Alert Service Bulletin 747– 38A2073, Revision 3, dated May 22, 2003 (referred to in the NPRM as an appropriate source of service information for accomplishing the prior or concurrent requirements). We partially agree. We agree with Boeing that accomplishing the actions specified in Revisions 1 and 2 of Boeing Alert Service Bulletin 747–38A2073 is acceptable for compliance with the corresponding actions required by paragraph (g) of this AD. However, we do not agree that a change to the final rule is necessary. As mentioned in the Relevant Service Information section of the NPRM, AD 2001–24–30, amendment 39–12547 (66 FR 64104, December 12, 2001), requires installing drip shields in accordance with Boeing Alert Service Bulletin 747–38A–2073, Revision 2; or in accordance with Revision 1 or Original Release, dated November 30, 1989, if done before the effective date of that AD. In addition, paragraph (h) of this AD states, ‘‘Installation of drip shields before the effective date of this AD in accordance with paragraph (a) and Note 2 of AD 2001–24–30, amendment 39–12547, is acceptable for 71219 compliance with the corresponding actions in paragraph (g) of this AD.’’ We have made no change to the final rule in this regard. 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. Interim Action This is considered to be interim action. The manufacturer has advised that it currently is developing another modification that will address the unsafe condition identified in this AD. Once this modification is developed, approved, and available, the FAA might consider additional rulemaking. Costs of Compliance There are about 79 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.

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. 15:24 Dec 14, 2007 Parts 3 Authority for This Rulemaking VerDate Aug<31>2005 Average labor rate per hour Work hours 80 4,497 7,057 25 176,425 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.

SUPPLEMENTARY INFORMATION: 

Discussion

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to include an AD that would

[[Page 71219]]

apply to certain Boeing Model 747-200C and -200F series airplanes. That 
NPRM was published in the Federal Register on August 16, 2007 (72 FR 
45954). That NPRM proposed to require, among other actions, installing 
mounting brackets, support angles, and moisture curtains in the main 
equipment center.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. We have considered the comment received.

Request To Refer to Earlier Revision of a Referenced Service Bulletin

    Boeing requests that paragraph (g) of the NPRM be revised to 
include Boeing Alert Service Bulletin 747-38A2073, Revision 1, dated 
June 21, 1990; and Revision 2, dated April 26, 2001; as additional 
sources of service information for accomplishing the prior or 
concurrent requirements. Boeing states that this will align the NPRM 
with Boeing Alert Service Bulletin 747-38A2073, Revision 3, dated May 
22, 2003 (referred to in the NPRM as an appropriate source of service 
information for accomplishing the prior or concurrent requirements).
    We partially agree. We agree with Boeing that accomplishing the 
actions specified in Revisions 1 and 2 of Boeing Alert Service Bulletin 
747-38A2073 is acceptable for compliance with the corresponding actions 
required by paragraph (g) of this AD. However, we do not agree that a 
change to the final rule is necessary. As mentioned in the Relevant 
Service Information section of the NPRM, AD 2001-24-30, amendment 39-
12547 (66 FR 64104, December 12, 2001), requires installing drip 
shields in accordance with Boeing Alert Service Bulletin 747-38A-2073, 
Revision 2; or in accordance with Revision 1 or Original Release, dated 
November 30, 1989, if done before the effective date of that AD. In 
addition, paragraph (h) of this AD states, ``Installation of drip 
shields before the effective date of this AD in accordance with 
paragraph (a) and Note 2 of AD 2001-24-30, amendment 39-12547, is 
acceptable for compliance with the corresponding actions in paragraph 
(g) of this AD.'' We have made no change to the final rule in this 
regard.

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.

Interim Action

    This is considered to be interim action. The manufacturer has 
advised that it currently is developing another modification that will 
address the unsafe condition identified in this AD. Once this 
modification is developed, approved, and available, the FAA might 
consider additional rulemaking.

Costs of Compliance

    There are about 79 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.

                                                                     Estimated Costs

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
