SUPPLEMENTARY INFORMATION:
Discussion
We issued a supplemental notice of
proposed rulemaking (NPRM) to amend
14 CFR part 39 to include an
airworthiness directive (AD) that would
apply to certain Model 777–200, –300,
and –300ER series airplanes. That
supplemental NPRM was published in
the Federal Register on June 18, 2010
(75 FR 34663). The original NPRM (72
FR 3956, January 29, 2007) proposed to
require installing Teflon sleeving under
E:\FR\FM\16DER1.SGM
16DER1
Federal Register / Vol. 75, No. 241 / Thursday, December 16, 2010 / Rules and Regulations
the clamps of certain wire bundles
routed along the fuel tank boundary
structure, and cap sealing certain
penetrating fasteners of the main and
center fuel tanks. The supplemental
NPRM proposed to revise the original
NPRM by adding airplanes and adding
and removing certain requirements.
Comments
We gave the public the opportunity to
participate in developing this AD. We
considered the comments received.
jlentini on DSKJ8SOYB1PROD with RULES
Support for Supplemental NPRM
Boeing concurred with the content of
the supplemental NPRM. American
Airlines has a program in place to
address the actions in the proposed rule
and had no objection to the
supplemental NPRM.
Request To Extend Compliance Time
Air Transport Association (ATA), on
behalf of its member Delta Air Lines Inc.
(Delta), asked that the 60-month
compliance time in the supplemental
NPRM be extended to better align with
industry standard tank entry intervals.
Delta stated that the required
modifications will require entry into the
main and center fuel tanks, and Delta
opens those fuel tanks at 8- and 4-year
intervals, respectively. Delta added that
the compliance time of 60 months to
accomplish the corrective action will be
acceptable for work in the center fuel
tank but will force main tank entry
earlier than normally scheduled.
We do not agree to extend the
compliance time. In developing an
appropriate compliance time for this
action, we considered the urgency
associated with the subject unsafe
condition and the practical aspect of
accomplishing the required
modification within a period of time
that corresponds to the normal
scheduled maintenance for most
affected operators. In consideration of
these items, in addition to the unsafe
condition being electrical arcing in the
fuel tank, we have determined that a 60month interval will ensure an
acceptable level of safety. However,
according to the provisions of paragraph
(j)(1) of this AD, we may approve
requests to adjust the compliance time
if the request includes data proving that
the requested compliance time would
provide an acceptable level of safety.
We have not changed the AD in this
regard.
Request To Include Revision 3 of the
Referenced Service Bulletin
Continental Airlines (CAL) asked that
the supplemental NPRM be changed to
include Revision 3 of Boeing Service
VerDate Mar<15>2010
16:09 Dec 15, 2010
Jkt 223001
Bulletin 777–57A0050, instead of
Revision 2, dated May 14, 2009 (referred
to for the applicability and for
accomplishing certain actions in the
supplemental NPRM). CAL stated that
including Revision 3 may be necessary
to avoid the alternative methods of
compliance approval process because
technical errors still exist in Revision 2
of Boeing Service Bulletin 777–
57A0050.
We do not agree to include Revision
3 of the referenced service bulletin in
this AD, since Revision 3 of Boeing
Service Bulletin 777–57A0050 has not
yet been issued. Since Revision 2 of
Boeing Service Bulletin 777–57A0050 is
expected to be revised after issuance of
this AD to correct the discrepancies, we
might consider approving the revised
service bulletin as an alternative method
of compliance (AMOC), according to the
provisions of paragraph (j)(1) of this AD.
We have not changed the AD in this
regard.
Clarify Instructions for Continued
Airworthiness (ICA)
CAL stated that proper ICA must be
provided in order to prevent inadvertent
reversal of implemented changes that
can lead to violation requirements in the
final rule. CAL added that it requested
a copy of the ICA from Boeing to review
and better understand the approach
being taken to support the Special
Federal Aviation Regulation No. 88
(‘‘SFAR 88’’) program; however, the ICA
has not been received yet.
We acknowledge the commenter’s
concern. However, no new ICAs have
been developed for the design change
required by this AD. Operators and
owners are responsible for ensuring that
the configuration mandated by this AD
is maintained in accordance with
section 39.7 of the Federal Aviation
Regulations (14 CFR 39.7).
If any new airworthiness limitations
(AWLs) related to any of the design
features mandated by this AD are
developed, we may consider additional
rulemaking to mandate incorporations
of those AWLs into operators’
maintenance programs. We have not
changed the AD in regard to this issue.
The FAA is working with industry to
evaluate potential changes to the AD
process that are intended to more
clearly identify how to maintain
configurations that are required for AD
compliance.
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
There are 694 airplanes of the affected
design in the worldwide fleet. This AD
affects about 129 airplanes of U.S.
registry. We estimate that it will take
between 278 and 358 work-hours per
product to comply with the basic
requirements of this AD. Required parts
cost about $2,241 per product. The
average labor rate is $85 per work-hour.
Based on these figures, we estimate the
cost of these actions to the U.S.
operators to be between $3,337,359 and
$4,214,559, or $25,871 and $32,671 per
product, depending on airplane
configuration.
Currently, there are no affected Group
3 airplanes on the U.S. Register.
However, if a Group 3 airplane is
imported and placed on the U.S.
Register in the future, the required
actions will take about 480 work hours,
at an average labor rate of $85 per work
hour. Required parts cost about $2,241
per product. Based on these figures, we
estimate the cost of this AD for Group
3 airplanes to be $43,041 per airplane.
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,
E:\FR\FM\16DER1.SGM
16DER1
78590
Federal Register / Vol. 75, No. 241 / Thursday, December 16, 2010 / Rules and Regulations
(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.

panel with improved switches and
doing the associated wiring changes.
This AD also requires, for certain
airplanes, installation of a mounting
bracket for the new indicator lights.
This AD also requires a revision to the
maintenance program to incorporate
airworthiness limitation No. 28–AWL–
22. This AD also requires a revision to
the airplane flight manual to advise the
flightcrew what to do in the event that
the pump low pressure light on the
flight engineer’s panel does not
illuminate when the pump is selected
off. This AD was prompted by fuel
system reviews conducted by the
manufacturer. We are issuing this AD to
prevent uncommanded operation of the
override/jettison pumps of the center
wing tanks, and failure to manually shut
off the override/jettison pumps at the
correct time, either of which could lead
to an ignition source inside the center
wing tank. This condition, in
combination with flammable fuel
vapors, could result in a center fuel tank
explosion and consequent loss of the
airplane.
This AD is effective January 20,
2011.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a supplemental notice of
proposed rulemaking (NPRM) to amend
14 CFR part 39 to include an
airworthiness directive (AD) that would
apply to the specified products. That
supplemental NPRM published in the
Federal Register on October 1, 2010 (75
FR 60661). That supplemental NPRM
proposed to require adding two new
indicator lights on the P10 panel to
inform the captain and first officer of a
low pressure condition in the left and
right override/jettison pumps of the
center wing tanks. That supplemental
NPRM also proposed to require
replacing the left and right override/
jettison switches on the M154 fuel
control module on the P4 panel with
improved switches and doing the
associated wiring changes. That
supplemental NPRM also proposed to
require, for certain airplanes,
installation of a mounting bracket for
the new indicator lights. That
supplemental NPRM also proposed to
require a revision to the maintenance
program to incorporate airworthiness

Airworthiness Directives; The Boeing Company Model 777-200, -300,
and -300ER Series Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are adopting a new airworthiness directive (AD) for certain
Model 777-200, -300, and -300ER series airplanes. This AD requires
installing Teflon sleeving under the clamps of certain wire bundles
routed along the fuel tank boundary structure, and cap sealing certain
penetrating fasteners of the main and center fuel tanks. This AD
results from fuel system reviews conducted by the manufacturer. We are
issuing this AD to prevent electrical arcing on the fuel tank boundary
structure or inside the fuel tanks, which could result in a fire or
explosion.
DATES: This AD is effective January 20, 2011.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a supplemental notice of proposed rulemaking (NPRM) to
amend 14 CFR part 39 to include an airworthiness directive (AD) that
would apply to certain Model 777-200, -300, and -300ER series
airplanes. That supplemental NPRM was published in the Federal Register
on June 18, 2010 (75 FR 34663). The original NPRM (72 FR 3956, January
29, 2007) proposed to require installing Teflon sleeving under
[[Page 78589]]
the clamps of certain wire bundles routed along the fuel tank boundary
structure, and cap sealing certain penetrating fasteners of the main
and center fuel tanks. The supplemental NPRM proposed to revise the
original NPRM by adding airplanes and adding and removing certain
requirements.
Comments
We gave the public the opportunity to participate in developing
this AD. We considered the comments received.
Support for Supplemental NPRM
Boeing concurred with the content of the supplemental NPRM.
American Airlines has a program in place to address the actions in the
proposed rule and had no objection to the supplemental NPRM.
Request To Extend Compliance Time
Air Transport Association (ATA), on behalf of its member Delta Air
Lines Inc. (Delta), asked that the 60-month compliance time in the
supplemental NPRM be extended to better align with industry standard
tank entry intervals. Delta stated that the required modifications will
require entry into the main and center fuel tanks, and Delta opens
those fuel tanks at 8- and 4-year intervals, respectively. Delta added
that the compliance time of 60 months to accomplish the corrective
action will be acceptable for work in the center fuel tank but will
force main tank entry earlier than normally scheduled.
We do not agree to extend the compliance time. In developing an
appropriate compliance time for this action, we considered the urgency
associated with the subject unsafe condition and the practical aspect
of accomplishing the required modification within a period of time that
corresponds to the normal scheduled maintenance for most affected
operators. In consideration of these items, in addition to the unsafe
condition being electrical arcing in the fuel tank, we have determined
that a 60-month interval will ensure an acceptable level of safety.
However, according to the provisions of paragraph (j)(1) of this AD, we
may approve requests to adjust the compliance time if the request
includes data proving that the requested compliance time would provide
an acceptable level of safety. We have not changed the AD in this
regard.
Request To Include Revision 3 of the Referenced Service Bulletin
Continental Airlines (CAL) asked that the supplemental NPRM be
changed to include Revision 3 of Boeing Service Bulletin 777-57A0050,
instead of Revision 2, dated May 14, 2009 (referred to for the
applicability and for accomplishing certain actions in the supplemental
NPRM). CAL stated that including Revision 3 may be necessary to avoid
the alternative methods of compliance approval process because
technical errors still exist in Revision 2 of Boeing Service Bulletin
777-57A0050.
We do not agree to include Revision 3 of the referenced service
bulletin in this AD, since Revision 3 of Boeing Service Bulletin 777-
57A0050 has not yet been issued. Since Revision 2 of Boeing Service
Bulletin 777-57A0050 is expected to be revised after issuance of this
AD to correct the discrepancies, we might consider approving the
revised service bulletin as an alternative method of compliance (AMOC),
according to the provisions of paragraph (j)(1) of this AD. We have not
changed the AD in this regard.
Clarify Instructions for Continued Airworthiness (ICA)
CAL stated that proper ICA must be provided in order to prevent
inadvertent reversal of implemented changes that can lead to violation
requirements in the final rule. CAL added that it requested a copy of
the ICA from Boeing to review and better understand the approach being
taken to support the Special Federal Aviation Regulation No. 88 (``SFAR
88'') program; however, the ICA has not been received yet.
We acknowledge the commenter's concern. However, no new ICAs have
been developed for the design change required by this AD. Operators and
owners are responsible for ensuring that the configuration mandated by
this AD is maintained in accordance with section 39.7 of the Federal
Aviation Regulations (14 CFR 39.7).
If any new airworthiness limitations (AWLs) related to any of the
design features mandated by this AD are developed, we may consider
additional rulemaking to mandate incorporations of those AWLs into
operators' maintenance programs. We have not changed the AD in regard
to this issue.
The FAA is working with industry to evaluate potential changes to
the AD process that are intended to more clearly identify how to
maintain configurations that are required for AD compliance.
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
There are 694 airplanes of the affected design in the worldwide
fleet. This AD affects about 129 airplanes of U.S. registry. We
estimate that it will take between 278 and 358 work-hours per product
to comply with the basic requirements of this AD. Required parts cost
about $2,241 per product. The average labor rate is $85 per work-hour.
Based on these figures, we estimate the cost of these actions to the
U.S. operators to be between $3,337,359 and $4,214,559, or $25,871 and
$32,671 per product, depending on airplane configuration.
Currently, there are no affected Group 3 airplanes on the U.S.
Register. However, if a Group 3 airplane is imported and placed on the
U.S. Register in the future, the required actions will take about 480
work hours, at an average labor rate of $85 per work hour. Required
parts cost about $2,241 per product. Based on these figures, we
estimate the cost of this AD for Group 3 airplanes to be $43,041 per
airplane.
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,
[[Page 78590]]
(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.
