subgroups of firms, and key issues from 

the manufacturers’ perspective. 

As part of the MIA, DOE intends to 

analyze impacts of potential energy 

conservation standards on small 

business manufacturers of covered 

products. DOE intends to use the Small 

Business Administration’s (SBA) small 

business size standards to determine 

whether manufacturers qualify as small 

businesses. The size standards are listed 

by North American Industry 

Classification System (NAICS) code and 

industry description.14 Manufacturing 

of residential clothes dryers is classified 

under NAICS 335224, ‘‘Household 

Laundry Equipment Manufacturing.’’ 

The SBA sets a threshold of 1,000 

employees or less for an entity to be 

considered as a small business for this 

category. This 1,000-employee threshold 

would include all employees in a 

business’s parent company and any 

other subsidiaries. 

DOE intends to conduct a market 

survey using publicly available 

information to identify potential small 

manufacturers using the abovementioned size threshold. In identifying 

potential small businesses, DOE 

generally uses its Compliance 

Certification Management System 

(CCMS), industry trade association 

membership directories (including 

AHAM), individual company Web sites, 

and market research tools (e.g., Hoovers 

reports) to create a list of companies that 

manufacture or sell products covered by 

this rulemaking. 

Issue J.1 DOE requests comment on 

whether there are any small business 

manufacturers of residential clothes 

dryers that it should consider in its 

analysis. 

III. Submission of Comments 

DOE invites all interested parties to 

submit in writing by May 11, 2015, 

comments and information on matters 

addressed in this notice and on other 

matters relevant to DOE’s consideration 

of new or amended energy 

conservations standards for residential 

clothes dryers. After the close of the 

comment period, DOE will collect data, 

conduct analyses, and review public 

comments, as needed. These actions 

will aid in the development of a NOPR 

for residential clothes dryers if DOE 

decides to amend the standards for such 

products. 

DOE considers public participation to 

be a very important part of the process 

for developing test procedures and 

energy conservation standards. DOE 

actively encourages the participation 

and interaction of the public during the 

comment period in each stage of the 

rulemaking process. Interactions with 

and between members of the public 

provide a balanced discussion of the 

issues and assist DOE in the rulemaking 

process. Anyone who wishes to be 

added to the DOE mailing list to receive 

future notices and information about 

this rulemaking should contact Ms. 

Brenda Edwards at (202) 586–2945, or 

via email at Brenda.Edwards@

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to supersede 

Airworthiness Directive (AD) 2005–18– 

18, which applies to certain The Boeing 

Company Model 757 airplanes. AD 

2005–18–18 currently requires 

inspections of certain wire bundles in 

the left and right engine-to-wing aft 

fairings for discrepancies; installation of 

back-to-back p-clamps between the wire 

and hydraulic supply tube at the aft end 

of the right-hand strut only; and 

associated re-routing of the wire 

bundles, if necessary. Since we issued 

AD 2005–18–18, we have determined 

that the service information referenced 

in AD 2005–18–18 did not adequately 

address fuel shutoff valve (FSV) wires at 

the aft end of the struts. This proposed 

AD would add an installation of spiral 

cable wrap on FSV wires at the aft end 

of the strut, for both left and right 

engines, and related investigative and 

corrective actions. We are proposing 

this AD to prevent chafing between the 

wire bundle and the structure of the aft 

fairing, which could result in electrical 

arcing and subsequent ignition of 

flammable vapors and possible 

uncontrollable fire. 

DATES: We must receive comments on 

this proposed AD by May 11, 2015. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following

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 

On August 31, 2005, we issued AD 

2005–18–18, Amendment 39–14258 (70 

FR 53554, September 9, 2005), for 

certain The Boeing Company Model 

757–200, –200PF, –200CB, and –300 

series airplanes. AD 2005–18–18 

requires inspections of certain wire 

bundles in the left and right engine-towing aft fairings for discrepancies; 

installation of back-to-back p-clamps 

between the wire and hydraulic supply 

tube at the aft end of the right-hand strut 

only; and associated re-routing of the 

wire bundles, if necessary. AD 2005– 

18–18 resulted from a report indicating 

that a circuit breaker for the fuel shutoff 

valve tripped due to a wire that chafed 

against the structure in the flammable 

leakage zone of the aft fairing, causing 

a short circuit. We issued AD 2005–18– 

18 to prevent chafing between the wire 

bundle and the structure of the aft 

fairing, which could result in electrical 

arcing and subsequent ignition of 

flammable vapors and possible 

uncontrollable fire. 

Actions Since AD 2005–18–18, 

Amendment 39–14258 (70 FR 53554, 

September 9, 2005), Was Issued 

Since we issued AD 2005–18–18, 

Amendment 39–14258 (70 FR 53554, 

September 9, 2005), we received a 

report that the service information 

referenced in AD 2005–18–18 did not 

adequately address FSV wires at the aft 

end of the strut, for both left and right 

engine struts. The proposed installation 

of tetrafluoroethylene spiral cable wrap 

on the FSV wires at the aft end of the 

strut would provide additional wiring 

protection. 

Related Service Information Under 1 

CFR Part 51 

We reviewed Boeing Alert Service 

Bulletins 757–28A0073 and 757– 

28A0074, both Revision 2, both dated 

June 4, 2009. The service information 

describes procedures for inspecting 

certain wire bundles in the left and right 

engine-to-wing aft fairings for 

discrepancies; installing back-to-back pclamps between the wire and hydraulic 

supply tube at the aft end of the righthand strut only; associated re-routing of 

the wire bundles, if necessary; and 

installing spiral cable wrap on FSV 

wires on the aft ends of the left and right 

engine struts, and related investigative 

and corrective actions. Refer to this 

service information for information on 

the procedures and compliance times. 

This service information is reasonably 

available; see ADDRESSES for ways to 

access this service information. 

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 retain all 

requirements of AD 2005–18–18, 

Amendment 39–14258 (70 FR 53554, 

September 9, 2005). This proposed AD 

would add a requirement to install 

spiral cable wrap on FSV wires at the aft 

end of the strut, for both left and right 

engines, and related investigative and 

corrective actions. This proposed AD 

would require accomplishing the 

actions specified in the service 

information identified previously. 

The phrase ‘‘related investigative 

actions’’ is used in this proposed AD. 

‘‘Related investigative actions’’ are 

follow-on actions that (1) are related to 

the primary action, and (2) further 

investigate the nature of any condition 

found. Related investigative actions in 

an AD could include, for example, 

inspections. 

The phrase ‘‘corrective actions’’ is 

used in this proposed AD. ‘‘Corrective 

actions’’ are actions that correct or 

address any condition found. Corrective 

actions in an AD could include, for 

example, repairs. 

Costs of Compliance 

We estimate that this proposed AD 

affects 346 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 product Cost on U.S. operators 

Inspection of certain wire bundles, and p-clamp installation [retained actions from 

AD 2005–18–18, Amendment 39–14258 (70 FR 

53554, September 9, 2005)].

Between 16 and 44 workhours × $85 per hour = Between $1,360 and $3,740.$600 Between $1,960 and $4,340 Between $678,160 and 

$1,501,640. 

Installation of spiral cable 

wrap [new proposed action].

10 work-hours × $85 per hour 

= $850.

$10 $860 ....................................... $297,560. 

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.

16320 Federal Register / Vol. 80, No. 59 / Friday, March 27, 2015 / Proposed Rules 

Regulatory Findings 

We have 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 that the 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. 

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: 

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

§ 39.13 [Amended] 

■ 2. The FAA amends § 39.13 by 

removing Airworthiness Directive (AD) 

2005–18–18, Amendment 39–14258 (70 

FR 53554, September 9, 2005), and 

adding the following new AD:

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to supersede 

Airworthiness Directive (AD) 2013–08– 

23, which applies to all The Boeing 

Company Model DC–10–10, DC–10– 

10F, DC–10–15, DC–10–30, DC–10–30F 

(KC–10A and KDC–10), DC–10–40, DC– 

10–40F, MD–10–10F, MD–10–30F, MD– 

11, and MD–11F airplanes. AD 2013– 

08–23 currently requires adding design 

features to detect electrical faults and to 

detect a pump running in an empty fuel 

tank. Since we issued AD 2013–08–23, 

we have determined that it is necessary 

to clarify the requirements for the 

design features and to remove a 

terminating action for certain 

inspections. This proposed AD would 

clarify certain requirements and remove 

a terminating action. This proposed AD 

would also provide an optional method 

of compliance for the proposed actions. 

We are proposing this AD to reduce the 

potential of ignition sources inside fuel 

tanks, which, in combination with 

flammable fuel vapors, could result in 

fuel tank explosions and consequent 

loss of the airplane. 

DATES: We must receive comments on 

this proposed AD by May 11, 2015. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR

Discussion 

On April 10, 2013, we issued AD 

2013–08–23, Amendment 39–17441 (78 

FR 24037, April 24, 2013), for all The 

Boeing Company Model DC–10–10, DC– 

10–10F, DC–10–15, DC–10–30, DC–10– 

30F (KC–10A and KDC–10), DC–10–40, 

DC–10–40F, MD–10–10F, MD–10–30F, 

MD–11, and MD–11F airplanes. AD 

2013–08–23 requires adding design 

features to detect electrical faults and to 

detect a pump running in an empty fuel 

tank. AD 2013–08–23 resulted from fuel 

system reviews conducted by the 

manufacturer. We issued AD 2013–08– 

23 to reduce the potential of ignition 

sources inside fuel tanks, which, in 

combination with flammable fuel 

vapors, could result in fuel tank 

explosions and consequent loss of the 

airplane. 

Actions Since AD 2013–08–23, 

Amendment 39–17441 (78 FR 24037, 

April 24, 2013), Was Issued 

Since we issued AD 2013–08–23, 

Amendment 39–17441 (78 FR 24037, 

April 24, 2013), we have determined
