densitometer wiring from causing
failure of the FQIS densitometer
resistors, which could result in an
ignition source inside the center or

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
certain Model 747–400, 747–400D, and
747–400F series airplanes. That NPRM
E:\FR\FM\01OCR1.SGM
01OCR1
Federal Register / Vol. 75, No. 190 / Friday, October 1, 2010 / Rules and Regulations
was published in the Federal Register
on February 11, 2010 (75 FR 6821). That
NPRM proposed to require installing a
hot short protector for the fuel quantity
indicating system of the center fuel tank
and, for certain airplanes, the horizontal
stabilizer fuel tank.
Comments
We gave the public the opportunity to
participate in developing this AD. We
considered the comments received from
The Boeing Company.
Request To Revise Preamble of the
NPRM
Boeing requests the following changes
to sections of the preamble of the
NPRM:
• In the section ‘‘Relevant Service
Information,’’ revise ‘‘We have received
Boeing Service Bulletin 74728A2266,
Revision 1, dated December 10, 2009
(for the CWTs)’’ to ‘‘We have received
Boeing Service Bulletin 74728A2266,
Revision 1, dated December 10, 2009
(for all airplanes),’’ because there are no
configurations of the Model 747–400
without the center fuel tank.
• Revise ‘‘Relevant Service
Information’’ to add the phrase ‘‘(for
airplanes with horizontal stabilizer
tanks)’’ to ‘‘Boeing Alert Service Bulletin
747–28A2267, dated December 18,
2008.’’ Boeing states that this service
bulletin adds a hot short protector on
the horizontal stabilizer tank (HST).
We acknowledge the commenter’s
requests. While the commenter’s
suggestions may clarify information that
the NPRM contained, these sections are
not included in the final rule. As a
result, we have not changed the AD in
regard to these issues.
Request To Clarify the FQIS Wire
Separation Requirement
Boeing requests that we clarify the
requirement of the FQIS wire separation
from the wiring of the other systems as
a result of implementing the actions
required by this AD. Boeing requests
that we revise the Discussion section of
the NPRM to state that after the actions
required by the AD are implemented,
then no further actions are required to
separate the FQIS wire from the wiring
of other systems.
We agree with the commenter that no
action is required for the undisturbed
portion of the densitometer wiring from
the HSP to the fuel quantity processor
unit at the electrical equipment bay.
This final rule requires the installation
of the HSP according to the
accomplishment instructions of the
applicable service bulletins. No part of
this AD implies or requires action for
the undisturbed portion of the
densitometer wiring. Therefore, we have
60615
not changed the final rule in regard to
this issue.
Request To Add Service Bulletin to
Credit Paragraph
Boeing requests that we revise
paragraph (h) of the NPRM to include
Boeing Alert Service Bulletin 747–
28A2266, Revision 1, dated December
10, 2009.
We do not agree to revise the AD,
because such a revision is unnecessary.
Paragraph (h) of this AD exists to give
credit for actions accomplished before
the effective date of this AD using
Boeing Alert Service Bulletin 747–
28A2266, dated December 18, 2008, and
paragraph (g) of this AD requires that
Revision 1 of this service bulletin is
used for the action specified in that
paragraph. We have not changed the AD
in regard to this issue.
Conclusion
We reviewed the relevant data,
considered the comments received, and
determined that air safety and the
public interest require adopting the AD
as proposed.
Costs of Compliance
We estimate that this AD affects 80
airplanes of U.S. registry. The following
table provides the estimated costs for
U.S. operators to comply with this AD.

Authority for This Rulemaking
mstockstill on DSKH9S0YB1PROD with RULES
Fleet cost
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

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,

dated December 10, 2009 (for the CWTs)'' to ``We have received Boeing
Service Bulletin 74728A2266, Revision 1, dated December 10, 2009 (for
all airplanes),'' because there are no configurations of the Model 747-
400 without the center fuel tank.
Revise ``Relevant Service Information'' to add the phrase
``(for airplanes with horizontal stabilizer tanks)'' to ``Boeing Alert
Service Bulletin 747-28A2267, dated December 18, 2008.'' Boeing states
that this service bulletin adds a hot short protector on the horizontal
stabilizer tank (HST).
We acknowledge the commenter's requests. While the commenter's
suggestions may clarify information that the NPRM contained, these
sections are not included in the final rule. As a result, we have not
changed the AD in regard to these issues.
Request To Clarify the FQIS Wire Separation Requirement
Boeing requests that we clarify the requirement of the FQIS wire
separation from the wiring of the other systems as a result of
implementing the actions required by this AD. Boeing requests that we
revise the Discussion section of the NPRM to state that after the
actions required by the AD are implemented, then no further actions are
required to separate the FQIS wire from the wiring of other systems.
We agree with the commenter that no action is required for the
undisturbed portion of the densitometer wiring from the HSP to the fuel
quantity processor unit at the electrical equipment bay. This final
rule requires the installation of the HSP according to the
accomplishment instructions of the applicable service bulletins. No
part of this AD implies or requires action for the undisturbed portion
of the densitometer wiring. Therefore, we have not changed the final
rule in regard to this issue.
Request To Add Service Bulletin to Credit Paragraph
Boeing requests that we revise paragraph (h) of the NPRM to include
Boeing Alert Service Bulletin 747-28A2266, Revision 1, dated December
10, 2009.
We do not agree to revise the AD, because such a revision is
unnecessary. Paragraph (h) of this AD exists to give credit for actions
accomplished before the effective date of this AD using Boeing Alert
Service Bulletin 747-28A2266, dated December 18, 2008, and paragraph
(g) of this AD requires that Revision 1 of this service bulletin is
used for the action specified in that paragraph. We have not changed
the AD in regard to this issue.
Conclusion
We reviewed the relevant data, considered the comments received,
and determined that air safety and the public interest require adopting
the AD as proposed.
Costs of Compliance
We estimate that this AD affects 80 airplanes of U.S. registry. 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
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.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.
Adoption of the Amendment
0
Accordingly, under the authority delegated to me by the Administrator,
the FAA amends 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
[[Page 60616]]
Sec. 39.13 [Amended]
0
2. The FAA amends Sec. 39.13 by adding the following new airworthiness
directive (AD):
2010-20-12 The Boeing Company: Amendment 39-16447; Docket No. FAA-
2010-0035; Directorate Identifier 2009-NM-066-AD.
Effective Date
(a) This AD is effective November 5, 2010.
Affected ADs
(b) None.
Applicability
(c) This AD applies to The Boeing Company Model 747-400, 747-
400D, and 747-400F series airplanes, certificated in any category;
as identified in the service bulletins listed in paragraphs (c)(1)
and (c)(2) of this AD.
(1) Boeing Service Bulletin 747-28A2266, Revision 1, dated
December 10, 2009.
(2) Boeing Alert Service Bulletin 747-28A2267, dated December
18, 2008.
Subject
(d) Air Transport Association (ATA) of America Code 28: Fuel.
Unsafe Condition
(e) This AD results from fuel system reviews conducted by the
manufacturer. The Federal Aviation Administration is issuing this AD
to prevent an electrical hot short from a source outside the fuel
quantity indicating system (FQIS) to the densitometer wiring from
causing failure of the FQIS densitometer resistors, which could
result in an ignition source inside the center or horizontal
stabilizer fuel tanks. An ignition source, in combination with
flammable fuel vapors, could result in a fuel tank explosion and
consequent loss of the airplane.
Compliance
(f) You are responsible for having the actions required by this
AD performed within the compliance times specified, unless the
actions have already been done.
Installation of Hot Short Protector (HSP)
(g) Within 60 months after the effective date of this AD: Do the
applicable installations of the HSP specified in paragraphs (g)(1)
and (g)(2) of this AD.
