Discussion We have received a report of fuel leaking from the wing leading edge area 34919 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 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 767 design review revealed that some of the design features in the Model 737 wing leading edge area also exist in Model 767 airplanes. Additional design reviews have led to similar findings in Model 757 and Model 747 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 747 airplanes. path in the leading edge area of the wing. The modification consists of changing the leading edge of the lower wing skin panels and the seal doors at outboard slat station (OSS) 424.097, and the wing ribs at OSS 464.475, through repairs and new parts installation. Additionally, the service information specifies applying sealant, hole filling compound, and leveling compound to the wing leading edge; and applying sealant to the wing ribs. Relevant Service Information We reviewed Boeing Special Attention Service Bulletin 767–57– 0121, dated October 7, 2010. This service information describes procedures for modifying the fluid drain Costs of Compliance 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. We estimate that this proposed AD affects 361 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: ESTIMATED COSTS Action Labor cost Parts cost Cost per product Cost on U.S. operators Leading edge fluid drainage modification ....... 22 work-hours × $85 per hour = $1,870 ........ $651 $2,521 $910,081 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. Authority for This Rulemaking jlentini on DSK4TPTVN1PROD with PROPOSALS 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. Regulatory Findings 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 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, VerDate Mar<15>2010 16:15 Jun 14, 2011 Jkt 223001 PO 00000 Frm 00006 Fmt 4702 Sfmt 4702 (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.

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 
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 767 design review revealed that some of the design features 
in the Model 737 wing leading edge area also exist in Model 767 
airplanes. Additional design reviews have led to similar findings in 
Model 757 and Model 747 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 747 
airplanes.

Relevant Service Information

    We reviewed Boeing Special Attention Service Bulletin 767-57-0121, 
dated October 7, 2010. This service information describes procedures 
for modifying the fluid drain path in the leading edge area of the 
wing. The modification consists of changing the leading edge of the 
lower wing skin panels and the seal doors at outboard slat station 
(OSS) 424.097, and the wing ribs at OSS 464.475, through repairs and 
new parts installation. Additionally, the service information specifies 
applying sealant, hole filling compound, and leveling compound to the 
wing leading edge; and applying sealant to the wing ribs.

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 affects 361 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                    Cost per       Cost on U.S.
               Action                        Labor cost           Parts cost        product         operators

Leading edge fluid drainage           22 work-hours x $85 per            $651           $2,521         $910,081
 modification.                         hour = $1,870.
----------------------------------------------------------------------------------------------------------------

    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.
