VerDate Sep<11>2014 16:37 Dec 16, 2014 Jkt 235001 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– 2014–0926; Directorate Identifier 2014– NM–085–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 It was determined by analysis that, within a limited speed/Mach/altitude envelope and with specific payload and fuel conditions, divergent flutter could occur on Model 747–8 and 747–8F airplanes with 0% tail fuel during a high g-load maneuver (>1.6 g) in combination with any of the following system failures: • Dual hydraulic failure resulting in a free outboard (OB) aileron, free inboard (IB) elevator, and free OB elevator; • Dual electrical system failure resulting in both OB ailerons free; • System failures resulting in a free OB aileron; • System failures resulting in a free IB elevator; and • Latent excessive IB elevator freeplay. We are proposing this AD to prevent certain system failures from resulting in divergent flutter, and subsequent loss of continued safe flight and landing. Relevant Service Information We reviewed the following service information. For information on the procedures and compliance times, see this service information at https:// www.regulations.gov by searching for and locating Docket No. FAA–2014– 0926. • Boeing Alert Service Bulletin 747– 27A2506, February 3, 2014. • Boeing Alert Service Bulletin 747– 27A2513, Revision 1, dated July 18, 2014. We have also reviewed Boeing 747–8/ 8F Certification Maintenance Requirements (CMRs) Document D011U721–02–03, Revision December PO 00000 Frm 00029 Fmt 4702 Sfmt 4702 75101 2013, which contains the following tasks in Section G., ‘‘CMR Tasks:’’ • Item Numbers 27–CMR–10, ‘‘Lubricate inboard elevator hinge bearings.’’ • Item Number 27–CMR–11, ‘‘Functional check of inboard elevator hinge bearing and power control unit rod end bearing freeplay.’’ 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. Explanation of Applicability, Compliance Time, and Repetitive Intervals The applicability in paragraph (c) and the compliance times and repetitive intervals in paragraph (i) of this proposed AD are based on airplane utilization. Model 747–8 airplanes referred to as Boeing Business Jets (BBJs) are designated as low utilization airplanes and are maintained under a Boeing Manufacturer’s Recommended Program (MRP). The Boeing MRP is limited to airplanes operated less than 1,200 flight hours per calendar year. Therefore, this proposed AD has different implementation task intervals and repetitive intervals for these low utilization airplanes due to unique operations. Explanation of ‘‘RC’’ Steps in Service Information The FAA worked in conjunction with industry, under the Airworthiness Directives Implementation Aviation Rulemaking Committee, to enhance the AD system. One enhancement was a new process for annotating which steps in the service information are required for compliance with an AD. Differentiating these steps from other tasks in the service information is expected to improve an owner’s/ operator’s understanding of crucial AD requirements and help provide consistent judgment in AD compliance. The actions specified in the service information described previously include steps that are labeled as RC (required for compliance) because these steps have a direct effect on detecting, preventing, resolving, or eliminating an identified unsafe condition. E:\FR\FM\17DEP1.SGM 17DEP1 75102 Federal Register / Vol. 79, No. 242 / Wednesday, December 17, 2014 / Proposed Rules As noted in the specified service information, steps labeled as RC must be done to comply with the proposed AD. However, 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 service information without obtaining approval of an alternative method of compliance (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 will require approval of an AMOC. Costs of Compliance We estimate that this proposed AD affects 8 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: ESTIMATED COSTS Cost per product Labor cost Replacement of LCEs ..................................... Replacement of IB elevator PCPs and installation of external IB elevator compensators. Revision to maintenance or inspection program. 4 work-hours × $85 per hour = $340 ............. 57 work-hours × $85 per hour = $4,845 ........ $0 44,894 $340 49,739 $2,720 397,912 1 work-hour × $85 per hour = $85 ................. 0 85 680 According to the manufacturer, all 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. tkelley on DSK3SPTVN1PROD 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, VerDate Sep<11>2014 16:37 Dec 16, 2014 Jkt 235001 Parts cost Cost on U.S. operators Action (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.

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 747-8 and 747-8F airplanes. This 
proposed AD was prompted by an analysis, which determined that in a 
limited flight envelope with specific conditions, divergent flutter 
could occur during a high g-load maneuver in combination with certain 
system failures. This proposed AD would require replacing the lateral 
control electronic (LCE)

[[Page 75101]]

modules, replacing the inboard elevator power control packages (PCPs), 
installing new external compensators for the PCPs, and revising the 
maintenance or inspection program. We are proposing this AD to prevent 
certain system failures from resulting in divergent flutter, and 
subsequent loss of continued safe flight and landing.

DATES: We must receive comments on this proposed AD by February 2, 
2015.

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

Discussion

    It was determined by analysis that, within a limited speed/Mach/
altitude envelope and with specific payload and fuel conditions, 
divergent flutter could occur on Model 747-8 and 747-8F airplanes with 
0% tail fuel during a high g-load maneuver (>1.6 g) in combination with 
any of the following system failures:
     Dual hydraulic failure resulting in a free outboard (OB) 
aileron, free inboard (IB) elevator, and free OB elevator;
     Dual electrical system failure resulting in both OB 
ailerons free;
     System failures resulting in a free OB aileron;
     System failures resulting in a free IB elevator; and
     Latent excessive IB elevator freeplay.
    We are proposing this AD to prevent certain system failures from 
resulting in divergent flutter, and subsequent loss of continued safe 
flight and landing.

Relevant Service Information

    We reviewed the following service information. For information on 
the procedures and compliance times, see this service information at 
https://www.regulations.gov by searching for and locating Docket No. 
FAA-2014-0926.
     Boeing Alert Service Bulletin 747-27A2506, February 3, 
2014.
     Boeing Alert Service Bulletin 747-27A2513, Revision 1, 
dated July 18, 2014.
    We have also reviewed Boeing 747-8/8F Certification Maintenance 
Requirements (CMRs) Document D011U721-02-03, Revision December 2013, 
which contains the following tasks in Section G., ``CMR Tasks:''
     Item Numbers 27-CMR-10, ``Lubricate inboard elevator hinge 
bearings.''
     Item Number 27-CMR-11, ``Functional check of inboard 
elevator hinge bearing and power control unit rod end bearing 
freeplay.''

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.

Explanation of Applicability, Compliance Time, and Repetitive Intervals

    The applicability in paragraph (c) and the compliance times and 
repetitive intervals in paragraph (i) of this proposed AD are based on 
airplane utilization. Model 747-8 airplanes referred to as Boeing 
Business Jets (BBJs) are designated as low utilization airplanes and 
are maintained under a Boeing Manufacturer's Recommended Program (MRP). 
The Boeing MRP is limited to airplanes operated less than 1,200 flight 
hours per calendar year. Therefore, this proposed AD has different 
implementation task intervals and repetitive intervals for these low 
utilization airplanes due to unique operations.

Explanation of ``RC'' Steps in Service Information

    The FAA worked in conjunction with industry, under the 
Airworthiness Directives Implementation Aviation Rulemaking Committee, 
to enhance the AD system. One enhancement was a new process for 
annotating which steps in the service information are required for 
compliance with an AD. Differentiating these steps from other tasks in 
the service information is expected to improve an owner's/operator's 
understanding of crucial AD requirements and help provide consistent 
judgment in AD compliance. The actions specified in the service 
information described previously include steps that are labeled as RC 
(required for compliance) because these steps have a direct effect on 
detecting, preventing, resolving, or eliminating an identified unsafe 
condition.

[[Page 75102]]

    As noted in the specified service information, steps labeled as RC 
must be done to comply with the proposed AD. However, 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 service 
information without obtaining approval of an alternative method of 
compliance (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 will require approval of an AMOC.

Costs of Compliance

    We estimate that this proposed AD affects 8 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

 program.                                hour = $85.
----------------------------------------------------------------------------------------------------------------

    According to the manufacturer, all 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.
