SUPPLEMENTARY INFORMATION: VerDate Sep<11>2014 19:05 Feb 29, 2016 Jkt 238001 Comments Invited We invite you to send any written relevant data, views, or arguments about this proposal. Send your comments to an address listed under the ADDRESSES section. Include ‘‘Docket No. FAA– 2016–3986; Directorate Identifier 2015– NM–147–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 The manufacturer has determined that a certain fastener type in the fuel tank walls has insufficient bond to the structure, and an electrical wiring short could cause arcing to occur at the ends of fasteners in the fuel tanks. Potential ignition sources in the fuel tank in the event of a lightning strike or highpowered short circuit, if not corrected, could result in a fire or explosion. Related Rulemaking On September 17, 2007, we issued AD 2007–20–01, Amendment 39–15211 (72 FR 54533, September 26, 2007), applicable to certain The Boeing Company Model 747–100B SUD, 747– 200B, 747–200C, 747–200F, 747–300, 747–400, 747–400D, 747–400F, and 747SP series airplanes. That AD requires reconfiguring the clamps of certain wire bundles and applying insulating sealant to certain fasteners inside the fuel tanks using Boeing Special Attention Service Bulletin 747– 57–2327, Revision 1, dated July 10, 2006, on airplane line numbers 696 through 1363. Airplane line numbers 1364 through 1419 were changed during production. The actions required by AD 2007–20–01 are intended to prevent arcing inside the fuel tanks in the event of a lightning strike or high-powered short circuit, which could result in a fuel tank explosion or fire. Since we issued AD 2007–20–01, Amendment 39–15211 (72 FR 54533, September 26, 2007), the FAA has determined that for certain The Boeing Company Model 747–400, 747–400D, PO 00000 Frm 00009 Fmt 4702 Sfmt 4702 and 747–400F series airplanes, a certain fastener type in the fuel tank walls has insufficient bond to the structure and that an electrical wiring short could cause arcing to occur at the ends of fasteners in the fuel tanks. We determined that certain clamp locations need to be changed to prevent possible ignition sources in the fuel tanks. These clamps were not installed at these locations during production and were not identified in Boeing Special Attention Service Bulletin 747–57– 2327, Revision 1, dated July 10, 2006. Therefore, it is necessary to install new clamps and TFE sleeves at these additional locations on the wire bundles of the front spars and rear spars of the left and right wings. Related Service Information Under 1 CFR Part 51 We reviewed Boeing Special Attention Service Bulletin 747–28– 2324, Revision 1, dated July 27, 2015. The service information describes procedures for installing new clamps and TFE sleeves on the wire bundles of the front spars and rear spars of the wings. The service information also describes procedures for inspecting TFE sleeves under the wire bundle clamps that were installed using the procedures specified in Boeing Special Attention Service Bulletin 747–28–2324, dated November 4, 2014, for correct installation, and replacing them if necessary. This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section. 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 135 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: E:\FR\FM\01MRP1.SGM 01MRP1 Federal Register / Vol. 81, No. 40 / Tuesday, March 1, 2016 / Proposed Rules 10539 ESTIMATED COSTS Action Labor cost Installation of wire bundle clamps Inspection ...................................... Up to 7 work-hours × $85 per hour = $595 .............. Up to 5 work-hours × $85 per hour = $425 .............. We have received no definitive data that would enable us to provide cost estimates for the on-condition actions specified in this proposed AD. asabaliauskas on DSK5VPTVN1PROD with PROPOSALS 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.

(AD 2013–10–03 superseded AD 2010– 02–10, Amendment 39–16181 (75 FR 4477, January 28, 2010)). Since we issued AD 2013–10–03, Amendment 39–17456 (78 FR 31386, May 24, 2013), we have determined that certain one-time inspections are no longer necessary, certain compliance times may be extended, and an optional terminating action should be provided. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2014– 0120R1, dated August 31, 2015 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for all Airbus Model A330– 200, –200 Freighter, and –300 series airplanes; and Model A340–200, –300, –500, and –600 series airplanes. The MCAI states: During a scheduled maintenance inspection on the Main Landing Gear (MLG), the bogie stop pad was found deformed and cracked. Upon removal of the bogie stop pad for replacement, the bogie beam was also found cracked. The results of a laboratory investigation indicated that an overload event had occurred and no fatigue propagation of the crack was evident. A second bogie beam crack was subsequently found on another aeroplane, located under a bogie stop pad which only had superficial paint damage. This condition, if not detected and corrected, could lead to landing gear bogie detachment from the aeroplane, or landing gear collapse, or a runway excursion, E:\FR\FM\01MRP1.SGM 01MRP1

Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain The Boeing Company Model 747-400, 747-400D, and 747-400F series 
airplanes. This proposed AD was prompted by a determination that a 
certain fastener type in the fuel tank walls has insufficient bond to 
the structure, and an electrical wiring short could cause arcing to 
occur at the ends of fasteners in the fuel tanks. This proposed AD 
would require the installation of new clamps and 
polytetrafluoroethylene (TFE) sleeves on the wire bundles of the front 
spars and rear spars of the wings. This proposed AD would also require 
inspecting the existing TFE sleeves under the wire bundle clamps for 
correct installation, and replacement if necessary. We are proposing

Discussion

    The manufacturer has determined that a certain fastener type in the 
fuel tank walls has insufficient bond to the structure, and an 
electrical wiring short could cause arcing to occur at the ends of 
fasteners in the fuel tanks. Potential ignition sources in the fuel 
tank in the event of a lightning strike or high-powered short circuit, 
if not corrected, could result in a fire or explosion.

Related Rulemaking

    On September 17, 2007, we issued AD 2007-20-01, Amendment 39-15211 
(72 FR 54533, September 26, 2007), applicable to certain The Boeing 
Company Model 747-100B SUD, 747-200B, 747-200C, 747-200F, 747-300, 747-
400, 747-400D, 747-400F, and 747SP series airplanes. That AD requires 
reconfiguring the clamps of certain wire bundles and applying 
insulating sealant to certain fasteners inside the fuel tanks using 
Boeing Special Attention Service Bulletin 747-57-2327, Revision 1, 
dated July 10, 2006, on airplane line numbers 696 through 1363. 
Airplane line numbers 1364 through 1419 were changed during production. 
The actions required by AD 2007-20-01 are intended to prevent arcing 
inside the fuel tanks in the event of a lightning strike or high-
powered short circuit, which could result in a fuel tank explosion or 
fire.
    Since we issued AD 2007-20-01, Amendment 39-15211 (72 FR 54533, 
September 26, 2007), the FAA has determined that for certain The Boeing 
Company Model 747-400, 747-400D, and 747-400F series airplanes, a 
certain fastener type in the fuel tank walls has insufficient bond to 
the structure and that an electrical wiring short could cause arcing to 
occur at the ends of fasteners in the fuel tanks. We determined that 
certain clamp locations need to be changed to prevent possible ignition 
sources in the fuel tanks. These clamps were not installed at these 
locations during production and were not identified in Boeing Special 
Attention Service Bulletin 747-57-2327, Revision 1, dated July 10, 
2006. Therefore, it is necessary to install new clamps and TFE sleeves 
at these additional locations on the wire bundles of the front spars 
and rear spars of the left and right wings.

Related Service Information Under 1 CFR Part 51

    We reviewed Boeing Special Attention Service Bulletin 747-28-2324, 
Revision 1, dated July 27, 2015. The service information describes 
procedures for installing new clamps and TFE sleeves on the wire 
bundles of the front spars and rear spars of the wings. The service 
information also describes procedures for inspecting TFE sleeves under 
the wire bundle clamps that were installed using the procedures 
specified in Boeing Special Attention Service Bulletin 747-28-2324, 
dated November 4, 2014, for correct installation, and replacing them if 
necessary. This service information is reasonably available because the 
interested parties have access to it through their normal course of 
business or by the means identified in the ADDRESSES section.

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

    We have received no definitive data that would enable us to provide 
cost estimates for the on-condition actions specified in this proposed 
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

    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.
