SUPPLEMENTARY INFORMATION: DOE 

published a NOPR in the Federal 

Register to make available and invite 

public comments on its analysis 

regarding potential energy conservation 

standards for hearth products. 80 FR 

7082 (Feb. 9, 2015). The document set 

a deadline for the submission of written 

comments by April 10, 2015. RH 

Peterson Co. requested an extension of 

the public comment period, stating that 

additional time is necessary to review 

the published analysis in order to 

prepare and submit comments. DOE has 

determined that extending the comment 

period to allow additional time for 

interested parties to submit comments is 

appropriate based on the foregoing 

reason. DOE believes that extending the 

comment period by 30 days will provide 

the public with sufficient time to submit 

comments responding to DOE’s 

analysis. Accordingly, DOE will 

consider any comments postmarked by 

May 11, 2015, and deems any comments 

received by that date to be timely 

submitted. 

Issued in Washington, DC, on April 1, 

2015.

Airworthiness Directives; Bombardier,

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

Bombardier, Inc. Model CL–600–2B19 

(Regional Jet Series 100 & 440) 

airplanes. This proposed AD was 

prompted by results of a design review 

indicating that the burst pressure of the 

flexible hose, used to vent oxygen from 

the high-pressure relief valve of the 

oxygen cylinder overboard, was lower 

than the opening pressure of the highpressure relief valve, which could cause 

the flexible hose to burst before it can 

vent the excess oxygen overboard. This 

proposed AD would require replacing 

the oxygen hose assembly with a new, 

improved assembly. We are proposing 

this AD to prevent the accumulation of 

oxygen in an enclosed space, which 

could result in an uncontrolled oxygenfed fire if an ignition source is nearby. 

DATES: We must receive comments on 

this proposed AD by May 28, 2015. 

ADDRESSES: You may send comments by 

any of the following methods:

Discussion 

Transport Canada Civil Aviation 

(TCCA), which is the airworthiness 

authority for Canada, has issued 

Canadian Airworthiness Directive CF– 

2014–36, dated October 17, 2014 

(referred to after this as the Mandatory 

Continuing Airworthiness Information, 

or ‘‘the MCAI’’), to correct an unsafe 

condition for certain Bombardier, Inc. 

Model CL–600–2B19 (Regional Jet 

Series 100 & 440) airplanes. The MCAI 

states: 

Design review found that the burst 

pressure of the flexible hose, used to vent 

oxygen from the high-pressure relief valve of 

the oxygen cylinder overboard, is lower than 

the opening pressure of the high-pressure 

relief valve. This could cause the flexible 

hose to burst before it is able to vent the 

excess oxygen overboard. If an ignition 

source is present, the accumulation of oxygen 

in an enclosed space may result in an 

uncontrolled oxygen-fed fire. 

This [Canadian] AD mandates the 

replacement of the oxygen hose assembly 

with a new design oxygen hose assembly. 

You may examine the MCAI in the 

AD docket on the Internet at http://

www.regulations.gov by searching for 

and locating Docket No. FAA–2015– 

0823. 

Related Service Information Under 1 

CFR Part 51 

Bombardier has issued Service 

Bulletin 601R–35–018, dated May 21, 

2013. The service information describes 

procedures for replacing the oxygen 

hose assembly with a new, improved 

assembly. The actions described in this 

service information are intended to 

correct the unsafe condition identified 

in the MCAI. This service information is 

reasonably available; see ADDRESSES for 

ways to access this service information. 

FAA’s Determination and Requirements 

of This Proposed AD 

This product has been approved by 

the aviation authority of another 

country, and is approved for operation 

in the United States. Pursuant to our 

bilateral agreement with the State of 

Design Authority, we have been notified 

of the unsafe condition described in the 

MCAI and service information 

referenced above. We are proposing this 

AD because we evaluated all pertinent 

information and determined an unsafe 

condition exists and is likely to exist or 

develop on other products of the same 

type design. 

Costs of Compliance 

We estimate that this proposed AD 

affects 575 airplanes of U.S. registry. 

We also estimate that it would take 

about 2 work-hours per product to 

comply with the basic requirements of 

this proposed AD. Required parts would 

cost about $0 per product. The average 

labor rate is $85 per work-hour. Based 

on these figures, we estimate the cost of 

this proposed AD on U.S. operators to 

be $97,750, or $170 per airplane. 

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 

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 


wreier-aviles on DSK5TPTVN1PROD with PROPOSALS
19572 Federal Register / Vol. 80, No. 70 / Monday, April 13, 2015 / Proposed Rules 

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 

■ 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 adding 

the following new airworthiness 

directive (AD):

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for all 

Viking Air Limited (Type Certificate 

Previously Held by Bombardier, Inc.) 

Model DHC–7–1 and DHC–7–100 

airplanes. This proposed AD was

This proposed AD would require a onetime detailed visual inspection for 

cracking in the outboard nacelles upper 

longeron channels and angles; and 

repair if necessary. We are proposing 

this AD to detect and correct cracks in 

the outboard nacelles upper longeron 

channels and angles, which could lead 

to the loss of stiffness in the forward 

engine mount; and possible catastrophic 

failure.
