ACTION: Notice of proposed rulemaking
(NPRM).
AGENCY:
We propose to adopt a new
airworthiness directive (AD) for the
products listed above. This proposed
AD would require modification of the
fluid drain path in the leading edge area
of the wing. This proposed AD was
prompted by a design review following
a ground fire incident and reports of
flammable fluid leaks from the wing
leading edge area onto the engine
exhaust area. We are proposing this AD
to prevent flammable fluid from leaking
onto the engine exhaust nozzle, which
could result in a fire.
DATES: We must receive comments on
this proposed AD by July 29, 2011.
ADDRESSES: You may send comments by
any of the following methods:

this proposal. Send your comments to
an address listed under the ADDRESSES
section. Include ‘‘Docket No. FAA–
2011–0566; Directorate Identifier 2010–
NM–271–AD’’ at the beginning of your
comments. We specifically invite
comments on the overall regulatory,
economic, environmental, and energy
aspects of this proposed AD. We will
consider all comments received by the
closing date and may amend this
proposed AD because of those
comments.
We will post all comments we
receive, without change, to https://
www.regulations.gov, including any
personal information you provide. We
will also post a report summarizing each
substantive verbal contact we receive
about this proposed AD.
Discussion
We have received a report of fuel
leaking from the wing leading edge area
at the inboard end of the number 5
leading edge slat of a Model 737
airplane. The leak was discovered
during a post-flight inspection with a
fuel quantity of over 2,500 pounds.
Subsequent investigation found that the
leak occurred in an area of the front spar
E:\FR\FM\14JNP1.SGM
14JNP1
34626
Federal Register / Vol. 76, No. 114 / Tuesday, June 14, 2011 / Proposed Rules
that does not have a proper drain path.
This led to the fuel draining onto the
engine exhaust nozzle. The leak appears
to have been caused by a loose retaining
nut of the slat track down stop. We are
proposing this AD to prevent flammable
fluid from leaking onto the engine
exhaust nozzle, which could result in a
fire.
A Model 747 design review revealed
that some of the design features in the
Model 737 wing leading edge area also
exist in Model 747 airplanes. Additional
design reviews have led to similar
findings in Model 757 and Model 767
airplanes. We have issued AD 2010–23–
13 Amendment 39–16502 (75 FR 68688,
November 9, 2009), for Model 757
airplanes, and are considering
rulemaking for Model 737 and Model
767 airplanes.
Relevant Service Information
We reviewed Boeing Special
Attention Service Bulletin 747–57–
2332, dated November 9, 2010. This
service information divides the affected
airplanes into 10 groups. For all groups,
this service information describes
procedures for modifying the fluid drain
path in the leading edge area of the
wing. The modification consists of
changing fluid dam assemblies at the
wing outboard leading edge station
(OLES) 1250, and installing seal
assemblies at OLES 1185. Additionally,
this service information specifies
changing the lower leading edge wing
panels through repairs, parts
installation, and installing drain tube
assemblies.
For Groups 1 through 6, this service
information also specifies installing
fluid dam assemblies at wing inboard
leading edge station 770.
FAA’s Determination
We are proposing this AD because we
evaluated all the relevant information
and determined the unsafe condition
described previously is likely to exist or
develop in other products of the same
type design.
Proposed AD Requirements
This proposed AD would require
accomplishing the actions specified in
the service information described
previously.
Costs of Compliance
We estimate that this proposed AD
will affect 258 airplanes of U.S. registry.
We estimate the following costs to
comply with this proposed 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.

According to the manufacturer, some

individuals. We do not control warranty
coverage for affected individuals. As a
result, we have included all costs in our

Regulatory Findings
We determined that this proposed AD
would not have federalism implications
under Executive Order 13132. This
proposed AD would 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 this proposed regulation:
(1) Is not a ‘‘significant regulatory
action’’ under Executive Order 12866,
(2) Is not a ‘‘significant rule’’ under
the DOT Regulatory Policies and
Procedures (44 FR 11034, February 26,
1979),
(3) Will not affect intrastate aviation
in Alaska, and
(4) 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.

installing fluid dam assemblies at wing inboard leading edge station
770.
FAA's Determination
We are proposing this AD because we evaluated all the relevant
information and determined the unsafe condition described previously is
likely to exist or develop in other products of the same type design.
Proposed AD Requirements
This proposed AD would require accomplishing the actions specified
in the service information described previously.
Costs of Compliance
We estimate that this proposed AD will affect 258 airplanes of U.S.
registry.
We estimate the following costs to comply with this proposed AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost on U.S.
Action Labor cost Parts cost Cost per product operators
----------------------------------------------------------------------------------------------------------------
Fluid drainage modification 95 work-hours x $85 per $33,609 $41,684 $5,960,812
(Groups 1-6) (143 airplanes). hour = $8,075.
Fluid drainage modification 90 work-hours x $85 per 29,304 36,954 4,249,710
(Groups 7-10) (115 airplanes). hour = $7,650.
----------------------------------------------------------------------------------------------------------------
According to the manufacturer, some of the costs of this proposed
AD may be covered under warranty, thereby reducing the cost impact on
affected individuals. We do not control warranty coverage for affected
individuals. As a result, we have included all costs in our cost
estimate.
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 determined that this proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would 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 this proposed
regulation:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866,
(2) Is not a ``significant rule'' under the DOT Regulatory Policies
and Procedures (44 FR 11034, February 26, 1979),
(3) Will not affect intrastate aviation in Alaska, and
(4) 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.
