DOE requests comment on its MPC calculation as a function of diameter equation and multipliers. 14. DOE did not consider variable pitch blades in its analysis. DOE requests information on the effect variable-pitch blades have on efficiency in the field, the mechanism of that effect, and how testing can be conducted to capture any benefit from variable-pitch blades. 15. DOE requests comment on any of the industry financials (working capital rate; net property, plant, and equipment rate; selling, general, and administrative expense rate; research and development rate; depreciation rate; capital expenditure rate, and tax rate) used in the GRIM (located in the ‘‘Financials’’ tab of the GRIM spreadsheet). 16. DOE requests comment on the use of 11.4 percent as the real industry manufacturer discount rate (also referred to as the weighted average cost of capital) for commercial and industrial fan manufacturers (located in the ‘‘Financials’’ tab of the GRIM spreadsheet). 17. DOE requests comment on the use of 1.45 as a manufacturer markup (this corresponds to a 31 percent gross margin) for all fan groups and efficiency levels in the base case (located in the ‘‘Markups’’ tab of the GRIM spreadsheet). DOE requests information regarding manufacturer markups and whether they vary by fan efficiency, fan group, fan subgroup, or any other attribute. 18. DOE requests comment on both its methodology of calculating total industry capital and product conversion costs and the specific industry average per model capital and product conversion cost estimates for each fan subgroup (located in the Conversion Cost spreadsheet). 19. DOE assumed that every fan model that did not meet a candidate standard level being analyzed would be redesigned to meet that level. DOE requests comment on this assumption and on what portion of fan models that do not meet a standard level would be redesigned to meet the level as opposed to being eliminated from the American market. 20. DOE seeks inputs on its characterization of market channels for the considered fan groups, particularly whether the channels include all intermediate steps, and estimated market shares of each channel. 21. DOE seeks inputs and comments on the estimates of flow operating points used in the energy use analysis VerDate Sep<11>2014 16:37 Dec 09, 2014 Jkt 235001 (expressed as a function of the flow at best efficiency point). 22.

Send your comments to an address listed under the ADDRESSES section. Include ‘‘Docket No. FAA– 2014–0920; Directorate Identifier 2014– NM–192–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 We received a report of a jettison fuel pump that was shut off by the automatic shutoff system during the center tank fuel scavenge process on a short-range flight. The manufacturer had made a design change to the fuel scavenge system to improve its operational reliability under cold temperatures. With this design change incorporated, the jettison fuel pumps in the main fuel tanks are operated every flight as part of the fuel scavenge system. For certain airplanes on which this change has been incorporated, the jettison fuel pumps are automatically shut off after four hours of operating the fuel scavenge system, or when a low pressure condition of the jettison fuel pump is detected under failure conditions such as a fuel leak. The manufacturer discovered that the jettison pump inlets can be uncovered during normal fuel scavenge operation depending on the flight duration (less than four hours) and fuel loading in the main fuel tanks. In addition, the automatic shutoff system can fail in a latent manner. If the automatic shutoff system fails and the jettison pump inlets are uncovered as expected during normal fuel scavenge operation on short-range flights of less than four hours, the jettison pump will run dry for an extended period of time. Extended dry running of the jettison fuel pumps can be a potential ignition source inside the main fuel tanks, and could cause a fuel tank fire or explosion in the event that the jettison pump overheats or has an electrical fault. Relevant Service Information We reviewed Boeing Special Attention Bulletin 777–28–0083, dated September 8, 2014. 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– 0920. 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 ‘‘RC’’ Steps or Procedures in Service Information The FAA worked in conjunction with industry, under the Airworthiness 73253 Directives Implementation Aviation Rulemaking Committee (AD ARC), to enhance the AD system. One enhancement was a new process for annotating which steps or procedures in the service information are required for compliance with an AD. Differentiating these steps or procedures 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 or procedures that are identified as RC (required for compliance) because these steps or procedures have a direct effect on detecting, preventing, resolving, or eliminating an identified unsafe condition. As noted in the specified service information, steps or procedures identified as RC must be done to comply with the proposed AD. However, steps or procedures that are not identified as RC are recommended. Those steps or procedures that are not identified 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 or procedures identified as RC can be done and the airplane can be put back in a serviceable condition. Any substitutions or changes to steps or procedures identified as RC will require approval of an AMOC. Costs of Compliance We estimate that this proposed AD affects 11 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: ESTIMATED COSTS Action Labor cost mstockstill on DSK4VPTVN1PROD with PROPOSALS Groups 1 through Group 4 airplanes: Hardware and software changes ....................... (7 airplanes) ....................................................... Group 5 airplanes: ELMS2 software update ....................................

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.

Subtitle I, section 106, describes the authority of the FAA Administrator. Subtitle VII: Aviation Programs, describes in more PO 00000 Cost per roduct Parts cost Frm 00015 Fmt 4702 Sfmt 4702 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 E:\FR\FM\10DEP1.SGM 10DEP1 73254 Federal Register / Vol. 79, No. 237 / Wednesday, December 10, 2014 / Proposed Rules 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.

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, -300ER, and 777F 
series airplanes. This proposed AD was prompted by a report of a 
jettison fuel pump that was shut off by the automatic shutoff system 
during the center tank fuel scavenge process on a short-range flight. 
This proposed AD would require making wiring changes, modifying certain 
power panels, installing electrical load management system software, 
and accomplishing a functional test. We are proposing this AD to 
prevent extended dry running of the jettison fuel pumps, which can be a 
potential ignition source inside the main fuel tanks, and consequent 
fuel tank fire or explosion in the event that the jettison pump 
overheats or has an electrical fault.

DATES: We must receive comments on this proposed AD by January 26, 
2015.

Discussion

    We received a report of a jettison fuel pump that was shut off by 
the automatic shutoff system during the center tank fuel scavenge 
process on a short-range flight. The manufacturer had made a design 
change to the fuel scavenge system to improve its operational 
reliability under cold temperatures. With this design change 
incorporated, the jettison fuel pumps in the main fuel tanks are 
operated every flight as part of the fuel scavenge system. For certain 
airplanes on which this change has been incorporated, the jettison fuel 
pumps are automatically shut off after four hours of operating the fuel 
scavenge system, or when a low pressure condition of the jettison fuel 
pump is detected under failure conditions such as a fuel leak. The 
manufacturer discovered that the jettison pump inlets can be uncovered 
during normal fuel scavenge operation depending on the flight duration 
(less than four hours) and fuel loading in the main fuel tanks. In 
addition, the automatic shutoff system can fail in a latent manner. If 
the automatic shutoff system fails and the jettison pump inlets are 
uncovered as expected during normal fuel scavenge operation on short-
range flights of less than four hours, the jettison pump will run dry 
for an extended period of time. Extended dry running of the jettison 
fuel pumps can be a potential ignition source inside the main fuel 
tanks, and could cause a fuel tank fire or explosion in the event that 
the jettison pump overheats or has an electrical fault.

Relevant Service Information

    We reviewed Boeing Special Attention Bulletin 777-28-0083, dated 
September 8, 2014. 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-2014-0920.

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 ``RC'' Steps or Procedures in Service Information

    The FAA worked in conjunction with industry, under the 
Airworthiness Directives Implementation Aviation Rulemaking Committee 
(AD ARC), to enhance the AD system. One enhancement was a new process 
for annotating which steps or procedures in the service information are 
required for compliance with an AD. Differentiating these steps or 
procedures 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 
or procedures that are identified as RC (required for compliance) 
because these steps or procedures have a direct effect on detecting, 
preventing, resolving, or eliminating an identified unsafe condition.
    As noted in the specified service information, steps or procedures 
identified as RC must be done to comply with the proposed AD. However, 
steps or procedures that are not identified as RC are recommended. 
Those steps or procedures that are not identified 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 or procedures identified as RC can be done and the 
airplane can be put back in a serviceable condition. Any substitutions 
or changes to steps or procedures identified as RC will require 
approval of an AMOC.

Costs of Compliance

    We estimate that this proposed AD affects 11 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
----------------------------------------------------------------------------------------------------------------
Groups 1 through Group 4 airplanes:
    Hardware and software changes.....  Up to 31 work[dash]hours          $1,286          $3,921         $27,447
    (7 airplanes).....................   x $85 per hour = $2,635.
Group 5 airplanes:
    ELMS2 software update.............  8 work-hours x $85 per                 0             680           2,720
    (4 airplanes).....................   hour = $680.
----------------------------------------------------------------------------------------------------------------

    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

[[Page 73254]]

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.

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

0
1. The authority citation for part 39 continues to read as follows:

    Authority:  49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

The Boeing Company: Docket No. FAA-2014-0920; Directorate Identifier 
2014-NM-192-AD.

(a) Comments Due Date

    We must receive comments by January 26, 2015.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to The Boeing Company Model 777-200, -200LR, 
300ER and 777F series airplanes, certificated in any category, as 
identified in Boeing Special Attention Service Bulletin 777-28-0083, 
dated September 8, 2014.

(d) Subject

    Air Transport Association (ATA) of America Code 28: Fuel.

(e) Unsafe Condition

    This AD was prompted by a report of a jettison fuel pump that 
was shut off by the automatic shutoff system during the center tank 
fuel scavenge process on a short-range flight. We are issuing this 
AD to prevent extended dry running of the jettison fuel pumps, which 
can be a potential ignition source inside the main fuel tanks, and 
consequent fuel tank fire or explosion in the event that the 
jettison pump overheats or has an electrical fault.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Wiring and Software Changes

    (1) For Groups 1 through 4 airplanes, as identified in Boeing 
Special Attention Service Bulletin 777-28-0083, dated September 8, 
2014: Within 36 months after the effective date of this AD, make 
wiring changes, modify power panels P110 and P210, install 
electrical load management system 2 (ELMS2) software, and accomplish 
the functional test and all applicable corrective actions, in 
accordance with the Accomplishment Instructions of Boeing Special 
Attention Service Bulletin 777-28-0083, dated September 8, 2014. Do 
all applicable corrective actions before further flight.
    (2) For Group 5 airplanes, as identified in Boeing Special 
Attention Service Bulletin 777-28-0083, dated September 8, 2014: 
Within 12 months after the effective date of this AD, install ELMS2 
software, and accomplish the functional test and all applicable 
corrective actions, in accordance with the Accomplishment 
Instructions of Boeing Special Attention Service Bulletin 777-28-
0083, dated September 8, 2014. Do all applicable corrective actions 
before further flight.
    Note 1 to paragraph (g) of this AD: GE Aviation Service Bulletin 
5000ELM-28-075, Revision 1, dated August 5, 2014; and GE Aviation 
Service Bulletin 6000ELM-28-076, Revision 1, dated August 5, 2014; 
are additional sources of guidance for modifying the P110 and P210 
panels, respectively.

(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)(l) of this AD. 
Information may be emailed to: 9-ANM-Seattle-ACO-AMOC-Requests@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 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 or procedures that 
are identified as RC (Required for Compliance), those steps or 
procedures must be done to comply with this AD; any steps or 
procedures that are not identified as RC are recommended. Those 
steps or procedures that are not identified 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 or 
procedures identified as RC can be done and the airplane can be put 
back in a serviceable condition. Any substitutions or changes to 
steps or procedures identified as RC require approval of an AMOC.
