Download as PDF 35968 Federal Register / Vol. 79, No. 122 / Wednesday, June 25, 2014 / Proposed Rules (b) Affected ADs None. (c) Applicability This AD applies to The Boeing Company Model 747–8 and 747–8F series airplanes; certificated in any category; having a Variable Number identified in paragraph 1.A., ‘‘Effectivity,’’ of Boeing Alert Service Bulletin 747–54A2238, dated January 31, 2014; and Variable Number RC573. (d) Subject Air Transport Association (ATA) of America Code 54, Nacelles/Pylons. (e) Unsafe Condition This AD was prompted by an analysis by the manufacturer, which revealed that the fuse pins for the strut-to-wing attachment of the outboard aft upper spar on struts Nos. 1 and 4 are susceptible to migration in the event of a failed fuse pin through bolt. We are issuing this AD to prevent migration of the fuse pins for the strut-to-wing attachment of the outboard aft upper spar on struts Nos. 1 and 4, which could result in the complete disconnect and loss of the strut-to-wing attachment load path for the outboard aft upper spar. The complete loss of the No. 1 or No. 4 outboard aft upper spar strut-to-wing attachment load path could result in divergent flutter in certain parts of the flight envelope, which could result in loss of control of the airplane. (f) Compliance Comply with this AD within the compliance times specified, unless already done. ehiers on DSK2VPTVN1PROD with PROPOSALS (g) Replacement of Fuse Pins and Access Cover Assemblies Within 48 months after the effective date of this AD: Replace the fuse pins for the outboard aft upper spar and the access cover assemblies on struts Nos. 1 and 4, with new fuse pins and access cover assemblies, in accordance with the Accomplishment Instructions of Boeing Alert Service Bulletin 747–54A2238, dated January 31, 2014. (h) Alternative Methods of Compliance (AMOCs) (1) The Manager, Seattle Aircraft Certification Office (ACO), FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19, send your request to your principal inspector or local Flight Standards District Office, as appropriate. If sending information directly to the manager of the ACO, send it to the attention of the person identified in paragraph (i)(1) of this AD. Information may be emailed to: 9-ANM-Seattle-ACO-AMOCRequests@faa.gov. (2) Before using any approved AMOC, notify your appropriate principal inspector, or lacking a principal inspector, the manager of the local flight standards district office/ certificate holding district office. (3) An AMOC that provides an acceptable level of safety may be used for any repair required by this AD if it is approved by the Boeing Commercial Airplanes Organization Designation Authorization (ODA) that has VerDate Mar<15>2010 14:17 Jun 24, 2014 Jkt 232001 been authorized by the Manager, Seattle ACO to make those findings. For a repair method to be approved, the repair must meet the certification basis of the airplane, and the approval must specifically refer to this AD. (4) If the service information contains steps that are labeled as RC (Required for Compliance), those steps must be done to comply with this AD; any steps that are not labeled as RC are recommended. Those steps that are not labeled as RC may be deviated from, done as part of other actions, or done using accepted methods different from those identified in the specified service information without obtaining approval of an AMOC, provided the steps labeled as RC can be done and the airplane can be put back in a serviceable condition. Any substitutions or changes to steps labeled as RC require approval of an AMOC.

SUPPLEMENTARY INFORMATION: 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– 2014–0342; Directorate Identifier 2014– NM–007–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 http:// 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 received reports of very high temperatures—up to 67 degrees Celsius (152 degrees Fahrenheit)—near the floor in the aft lower lobe cargo compartment. The operator noted that loose cargo blocked the cover plate for the bulk cargo ZTS. The aft cargo heat system is controlled by three temperature switches (two control switches and one overheat switch) located in the bulk cargo ZTS assembly. When the air inlet to this assembly becomes blocked by loaded or shifted cargo, the temperature switches fail to receive an adequate sample of compartment air. Under these conditions, the switches will not command the system valves properly, and the switches may fail to shut off the flow of hot air to the lower lobe cargo compartment, causing compartment temperatures to rise beyond 60 degrees Celsius (140 degrees Fahrenheit). This condition, if not corrected, could result in overheating of the aft lower lobe cargo compartment, where, if temperature sensitive cargo is present, the release of flammable vapors could result in a fire or explosion if exposed to an ignition source. 35969 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 identified previously, except as discussed under ‘‘Differences Between this Proposed AD and the Service Information.’’ Differences Between This Proposed AD and the Service Information We reviewed Boeing Special Attention Service Bulletins 747–21– 2544, Revision 1, dated September 30, 2013, and 747–21–2550, dated December 6, 2013. For information on the procedures and compliance times, see this service information at http:// www.regulations.gov by searching for Docket No. FAA–2014–0342. Although Boeing Special Attention Service Bulletin 747–21–2550, dated December 6, 2013, specifies Boeing Service Bulletin 747–21–2367 as a concurrent service bulletin for certain airplanes, this proposed AD would not include that requirement. This difference has been coordinated with Boeing. Certain airplane variable numbers are not identified in Boeing Special Attention Service Bulletins 747–21– 2544, Revision 1, dated September 30, 2013, and 747–21–2550, dated December 6, 2013. These variable numbers are affected by the identified unsafe condition, therefore, this proposed AD would require that the actions specified in paragraphs (g) and (h) of this AD, as applicable, be completed on these variable numbers. This difference has been coordinated with Boeing. FAA’s Determination Costs of Compliance We are proposing this AD because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or We estimate that this proposed AD affects 130 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: Relevant Service Information ESTIMATED COSTS Action Labor cost Parts cost Cost per product Cost on U.S. operators Install zone temperature sensor .......... 91 work-hours × $85 per hour = $7,735 ................... $7,545 $15,280 $1,986,400 We estimate the following costs to do the optional actions specified in this proposed AD.

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. ehiers on DSK2VPTVN1PROD with PROPOSALS List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.

ACTION: Proposed rule; request for comments. AGENCY: NMFS proposes regulations to implement Amendment 97 to the Fishery Management Plan for Groundfish of the Gulf of Alaska (FMP). If approved, Amendment 97 would limit Chinook salmon prohibited species catch (PSC) in Western and Central Gulf of Alaska (GOA) non-pollock trawl catcher/processor (C/P) and catcher vessel (CV) fisheries. This action would establish separate annual Chinook salmon PSC limits for trawl catcher/ processors (Trawl C/P Sector), trawl catcher vessels participating in the Central GOA Rockfish Program (Rockfish Program CV Sector), and trawl catcher vessels not participating in the Central GOA Rockfish Program (Non- ehiers on DSK2VPTVN1PROD with PROPOSALS SUMMARY: VerDate Mar<15>2010 14:17 Jun 24, 2014 Jkt 232001 Rockfish Program CV Sector) fishing for groundfish species other than pollock. If a sector reaches its Chinook salmon PSC limit, NMFS would prohibit further fishing for non-pollock groundfish by vessels in that sector. This action also would establish and clarify Chinook salmon retention and discard requirements for vessels, shoreside processors, and stationary floating processors participating in both the GOA pollock and non-pollock groundfish trawl fisheries. This action is necessary to minimize the catch of Chinook salmon to the extent practicable in the GOA non-pollock trawl fisheries. Amendment 97 is intended to promote the goals and objectives of the Magnuson-Stevens Fishery Conservation and Management Act (Magnuson-Stevens Act), the FMP, and other applicable laws.

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, 747-400F, 747-8F, 
and 747-8 series airplanes. This proposed AD was prompted by reports of 
very high temperatures, up to 67 degrees Celsius (152 degrees 
Fahrenheit), near the floor in the aft lower lobe cargo compartment. 
This proposed AD would require installing an additional zone 
temperature sensor (ZTS) in the aft cargo compartment. For certain 
airplanes, the proposed AD would first require installing tape and 
replacing the markers in the bulk cargo compartment, unless terminated 
by the early installation of the ZTS. We are proposing this AD to 
prevent overheating of the aft lower lobe cargo compartment, where, if 
temperature sensitive cargo is present, the release of flammable vapors 
could result in a fire or explosion if exposed to an ignition source.

DATES: We must receive comments on this proposed AD by August 11, 2014.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

Discussion

    We received reports of very high temperatures--up to 67 degrees 
Celsius (152 degrees Fahrenheit)--near the floor in the aft lower lobe 
cargo compartment. The operator noted that loose cargo blocked the 
cover plate for the bulk cargo ZTS. The aft cargo heat system is 
controlled by three temperature switches (two control switches and one 
overheat switch) located in the bulk cargo ZTS assembly. When the air 
inlet to this assembly becomes blocked by loaded or shifted cargo, the 
temperature switches fail to receive an adequate sample of compartment 
air. Under these conditions, the switches will not command the system 
valves properly, and the switches may fail to shut off the flow of hot 
air to the lower lobe cargo compartment, causing compartment 
temperatures to rise beyond 60 degrees Celsius (140 degrees 
Fahrenheit). This condition, if not corrected, could result in 
overheating of the aft lower lobe cargo compartment, where, if 
temperature sensitive cargo is present, the release of flammable vapors 
could result in a fire or explosion if exposed to an ignition source.

Relevant Service Information

    We reviewed Boeing Special Attention Service Bulletins 747-21-2544, 
Revision 1, dated September 30, 2013, and 747-21-2550, dated December 
6, 2013. For information on the procedures and compliance times, see 
this service information at http://www.regulations.gov by searching for 
Docket No. FAA-2014-0342.

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 identified previously, except as discussed 
under ``Differences Between this Proposed AD and the Service 
Information.''

Differences Between This Proposed AD and the Service Information

    Although Boeing Special Attention Service Bulletin 747-21-2550, 
dated December 6, 2013, specifies Boeing Service Bulletin 747-21-2367 
as a concurrent service bulletin for certain airplanes, this proposed 
AD would not include that requirement. This difference has been 
coordinated with Boeing.
    Certain airplane variable numbers are not identified in Boeing 
Special Attention Service Bulletins 747-21-2544, Revision 1, dated 
September 30, 2013, and 747-21-2550, dated December 6, 2013. These 
variable numbers are affected by the identified unsafe condition, 
therefore, this proposed AD would require that the actions specified in 
paragraphs (g) and (h) of this AD, as applicable, be completed on these 
variable numbers. This difference has been coordinated with Boeing.

Costs of Compliance

    We estimate that this proposed AD affects 130 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

                                                 Estimated Costs

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.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.
