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.

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.

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,

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
certain Boeing Model 747-200C and -200F series airplanes. This AD
requires, among other actions, installing mounting brackets, support
angles, and moisture curtains in the main equipment center. This AD
results from reports of water contamination in the electrical/
electronic units in the main equipment center. We are issuing this AD
to prevent water contamination of the electrical/electronic units,
which could cause the electrical/electronic units to malfunction, and
as a consequence, could adversely affect the airplane's continued safe
flight.
DATES: This AD becomes effective January 22, 2008.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in the AD as of January 22,
2008.

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.

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.
