13. 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.

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. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following

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– 

2014–0920; 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 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 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 http://

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

Action Labor cost Parts cost Cost per 

roduct 

Cost on U.S. 

operators 

Groups 1 through Group 4 airplanes: 

Hardware and software changes .......................

(7 airplanes) .......................................................

Up to 31 work-hours × $85 per hour = 

$2,635.

$1,286 $3,921 $27,447 

Group 5 airplanes: 

ELMS2 software update ....................................

(4 airplanes) .......................................................

8 work-hours × $85 per hour = $680 ... 0 680 2,720 

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 

mstockstill on DSK4VPTVN1PROD with PROPOSALS

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.
