[FR Doc. 2015–30821 Filed 12–22–15; 8:45 am] BILLING CODE 4910–13–P DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2015–7527; Directorate Identifier 2015–NM–094–AD] RIN 2120–AA64 Airworthiness Directives; The Boeing Company Airplanes Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 777–200, –200LR, –300, and –300ER series airplanes. This proposed AD was prompted by a report indicating that the manufacturer discovered locations where the control components and wiring of the left and right engine fuel spar valves do not have adequate physical separation to meet the redundant system separation requirements. This proposed AD would require modifying the wiring, and installing a new relay bracket and new location for the relay on the left and right engine fuel spar valves. This proposed AD would also require an inspection to identify the part number of the motor operated valve (MOV) actuators for the left and right engine fuel spar valves; replacement of specified MOV actuators with new MOV actuators; certain bonding resistance measurements; and applicable corrective actions. We are proposing this AD to prevent loss of control of both the left and right engine fuel spar valves during a single event, such as SUMMARY: E:\FR\FM\23DEP1.SGM 23DEP1 Federal Register / Vol. 80, No. 246 / Wednesday, December 23, 2015 / Proposed Rules asabaliauskas on DSK5VPTVN1PROD with PROPOSALS local wire bundle damage or a wire bundle fire, which could cause both engines to shut down or result in the inability to control an engine fire.

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– 2015–7527; Directorate Identifier 2015– NM–094–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 have received a report indicating that the manufacturer discovered locations where the control components and wiring of the left and right engine fuel spar valve do not have adequate physical separation to meet the redundant system separation requirements. The control relays for both the left and right engine fuel spar valves are located in the same panel, and the left and right fuel spar valve control wiring is routed in common wire bundles and share the same electrical connectors. This condition, if not corrected, could result in loss of control of both the left and right engine fuel spar valves during a single event, such as local wire bundle damage or a wire bundle fire, which could cause both engines to shut down or result in the inability to control an engine fire. Related Service Information Under 1 CFR Part 51 We reviewed Boeing Special Attention Service Bulletin 777–28– 0061, Revision 2, dated May 4, 2015. The service information describes procedures for modifying the wiring, and installing a new relay bracket and new location for the relay on the left and right engine fuel spar valves. We have also reviewed Boeing Service Bulletin 777–28A0034, Revision 3, PO 00000 Frm 00037 Fmt 4702 Sfmt 4702 79755 dated September 25, 2015. The service information describes procedures for an inspection of the MOV actuators of the left and right engine fuel spar valves for part number (P/N) MA20A1001–1, replacement of MOV actuators, measurement of the electrical resistance of the bond from the adapter plate to the airplane structure, and applicable corrective actions. 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 of this NPRM. Other Relevant Rulemaking AD 2013–05–03, Amendment 39– 17375 (78 FR 17290, March 21, 2013), was issued for certain Model 777–200, –200LR, –300, and –300ER series airplanes. AD 2013–05–03 requires an inspection to identify the part number of the MOV actuators of the main and center fuel tanks; replacing certain MOV actuators with new MOV actuators; and measuring the electrical resistance of the bond from the adaptor plate to the airplane structure, and doing corrective actions if necessary. AD 2013–05–03 refers to Boeing Service Bulletin 777– 28A0034, Revision 2, dated September 20, 2010, as the appropriate source of service information for accomplishing the required actions. In addition, AD 2015–19–01, Amendment 39–18264 (80 FR 55521, September 16, 2015), requires revising the maintenance or inspection program to add a new airworthiness limitation for a repetitive inspection of the fuel spar valve. 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 133 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: E:\FR\FM\23DEP1.SGM 23DEP1 79756 Federal Register / Vol. 80, No. 246 / Wednesday, December 23, 2015 / Proposed Rules ESTIMATED COSTS Action Labor cost Parts cost Installation and modification. 119 work-hours × $85 per hour = $10,115.

We have received no definitive data on the costs of the corrective actions for the bonding resistance measurement 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. (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. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES 1. The authority citation for part 39 continues to read as follows: ■ asabaliauskas on DSK5VPTVN1PROD with PROPOSALS Regulatory Findings Authority: 49 U.S.C. 106(g), 40113, 44701. 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 17:28 Dec 22, 2015 Jkt 238001 § 39.13 [Amended] 2.

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 777-200, -200LR, -300, and -300ER 
series airplanes. This proposed AD was prompted by a report indicating 
that the manufacturer discovered locations where the control components 
and wiring of the left and right engine fuel spar valves do not have 
adequate physical separation to meet the redundant system separation 
requirements. This proposed AD would require modifying the wiring, and 
installing a new relay bracket and new location for the relay on the 
left and right engine fuel spar valves. This proposed AD would also 
require an inspection to identify the part number of the motor operated 
valve (MOV) actuators for the left and right engine fuel spar valves; 
replacement of specified MOV actuators with new MOV actuators; certain 
bonding resistance measurements; and applicable corrective actions. We 
are proposing this AD to prevent loss of control of both the left and 
right engine fuel spar valves during a single event, such as

[[Page 79755]]

local wire bundle damage or a wire bundle fire, which could cause both 
engines to shut down or result in the inability to control an engine 
fire.

DATES: We must receive comments on this proposed AD by February 8, 
2016.

Discussion

    We have received a report indicating that the manufacturer 
discovered locations where the control components and wiring of the 
left and right engine fuel spar valve do not have adequate physical 
separation to meet the redundant system separation requirements. The 
control relays for both the left and right engine fuel spar valves are 
located in the same panel, and the left and right fuel spar valve 
control wiring is routed in common wire bundles and share the same 
electrical connectors. This condition, if not corrected, could result 
in loss of control of both the left and right engine fuel spar valves 
during a single event, such as local wire bundle damage or a wire 
bundle fire, which could cause both engines to shut down or result in 
the inability to control an engine fire.

Related Service Information Under 1 CFR Part 51

    We reviewed Boeing Special Attention Service Bulletin 777-28-0061, 
Revision 2, dated May 4, 2015. The service information describes 
procedures for modifying the wiring, and installing a new relay bracket 
and new location for the relay on the left and right engine fuel spar 
valves.
    We have also reviewed Boeing Service Bulletin 777-28A0034, Revision 
3, dated September 25, 2015. The service information describes 
procedures for an inspection of the MOV actuators of the left and right 
engine fuel spar valves for part number (P/N) MA20A1001-1, replacement 
of MOV actuators, measurement of the electrical resistance of the bond 
from the adapter plate to the airplane structure, and applicable 
corrective actions.
    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 of this 
NPRM.

Other Relevant Rulemaking

    AD 2013-05-03, Amendment 39-17375 (78 FR 17290, March 21, 2013), 
was issued for certain Model 777-200, -200LR, -300, and -300ER series 
airplanes. AD 2013-05-03 requires an inspection to identify the part 
number of the MOV actuators of the main and center fuel tanks; 
replacing certain MOV actuators with new MOV actuators; and measuring 
the electrical resistance of the bond from the adaptor plate to the 
airplane structure, and doing corrective actions if necessary. AD 2013-
05-03 refers to Boeing Service Bulletin 777-28A0034, Revision 2, dated 
September 20, 2010, as the appropriate source of service information 
for accomplishing the required actions.
    In addition, AD 2015-19-01, Amendment 39-18264 (80 FR 55521, 
September 16, 2015), requires revising the maintenance or inspection 
program to add a new airworthiness limitation for a repetitive 
inspection of the fuel spar valve.

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

    We have received no definitive data on the costs of the corrective 
actions for the bonding resistance measurement 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.
