submitting information that he or she 

believes to be confidential and exempt 

by law from public disclosure should 

submit via email two well-marked 

copies: One copy of the document 

marked ‘‘confidential’’ including all the 

information believed to be confidential, 

and one copy of the document marked 

‘‘non-confidential’’ with the information 

believed to be confidential deleted. DOE 

will make its own determination about 

the confidential status of the 

information and treat it according to its 

determination. 

It is DOE’s policy that all comments 

may be included in the public docket, 

without change and as received, 

including any personal information 

provided in the comments (except 

information deemed to be exempt from 

public disclosure). 

E. Issues on Which DOE Seeks Comment 

Although DOE welcomes comments 

on any aspect of this proposed 

determination, DOE is particularly 

interested in receiving comments and 

views of interested parties concerning 

the following issues: 

(1) DOE requests data and information 

related to achievable R-values of 

polyurethane foam insulation on 

jacketed UFHWSTs at thicknesses above 

3 inches. DOE also seeks comment on 

its understanding of the difficulties 

associated with applying more than 3 

inches of foam to jacketed UFHWSTs. 

(2) DOE seeks comment on the 

considered efficiency levels analyzed 

for UFHWSTs. Additionally, DOE seeks 

comment on its assumption that 

polyurethane foam has an R-value per 

inch of 6.25, up to a maximum 

thickness of 3 inches. 

(3) DOE requests comment on the 

inputs and assumptions used in its 

engineering analysis. In particular, DOE 

requests input on its choice of 

representative volumes, its assumptions 

about the typical coverage of various 

insulation materials, and its estimated 

R-values for each insulation material at 

each EL considered. 

(4) DOE requests comment on the 

appropriateness of its assumption 

regarding the use of a constant internal 

water temperature of 140 °F. 

(5) DOE requests comment on its 

assumption regarding the typical 

ambient temperatures for UFHWSTs 

installed indoors and outdoors. 

(6) DOE requests comment on its 

assumption that 10 percent of all 

UFHWST would be installed outdoors. 

DOE requests information on the typical 

capacities and R-values of outdoor 

equipment. 

(7) DOE requests comment on its 

assumption that outdoor installations 

would be limited to climate zones 1A, 

2A, and 2B. DOE requests information 

or data on the fraction of installations 

that occur within these, or other, 

climate zones. 

(8) DOE requests comment on its Tank 

Thermal Loss Model. 

(9) DOE requests data and information 

which can be used to estimate 

installation costs of UFHWSTs with 

modified dimensions. 

(10) DOE requests information and 

data characterizing the types of 

buildings where installation difficulties 

are likely to occur and to lead to 

increased installation cost, as well as 

the frequency with which such 

installation problems may arise. 

(11) DOE requests information and 

data characterizing the average 

installation costs for UFHWSTs at all 

different storage volumes. 

(12) DOE requests information and 

data characterizing the circumstances 

that would drive the decision to 

potentially restructure existing building 

spaces, including doorways and 

mechanical rooms, when installing a 

replacement UFHWST. For example, is 

the decision driven by a minimum 

building code requirement for door 

openings? 

(13) DOE requests comments 

generally regarding its stock analysis for 

UFHWSTs. 

(14) DOE requests comment regarding 

its assumption that there would be only 

one UFWHST per building. 

(15) DOE requests comment regarding 

its disaggregation of UFHWST stock by 

sector. 

(16) DOE requests comment on its 

assumption that UFHWSTs are not used 

for industrial process hot water storage. 

(17) DOE requests comment on its 

assumption of a 12-year lifetime for 

UFHWSTs similar to commercial 

electric hot water storage tanks. 

(18) DOE requests comment on its use 

of AEO 2021 trends as a scaler to project 

shipments to new construction. 

(19) DOE requests comment on its 

distribution of shipments by storage 

volume, and on its assumption that the 

distribution of shipments by storage 

volume does not change over time. 

(20) DOE requests comment regarding 

its applied efficiency distribution that 

99 percent of all units sold are currently 

at baseline (R–12.5).

Background 

The CAAI, which is the aviation 

authority for Israel, has issued CAAI AD 

I–57–2020–06–01, dated January 27, 

2021 (CAAI AD I–57–2020–06–01) (also 

referred to as the Mandatory Continuing 

Airworthiness Information, or the 

MCAI), to correct an unsafe condition 

for certain Gulfstream Aerospace LP 

Model Gulfstream G280 airplanes. 

This proposed AD was prompted by 

a report that during full-scale fatigue 

testing, a crack was found in the area of 

the attachment of the wing rib 0 to the 

front spar. The FAA is proposing this 

AD to address any cracking at the area 

of the wing rib 0 to the front spar, which 

could affect the structural integrity of 

the wing. See the MCAI for additional 

background information. 

Related Service Information Under 1 

CFR Part 51 

CAAI AD I–57–2020–06–01 specifies 

procedures for non-destructive testing 

(high frequency, mid frequency, bolt 

hole eddy current inspections, and a 

liquid (dye) penetrant inspection) for 

cracking on the forward (front) spar 

vertical stiffener and rib 0, installation 

of a doubler to the forward (front) spar 

and rib 0 attachment, and repair if 

necessary. This material 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. 

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 the 

FAA’s bilateral agreement with the State 

of Design Authority, the FAA has been 

notified of the unsafe condition 

described in the MCAI referenced 

above. The FAA is proposing this AD 

because the FAA 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 

CAAI AD I–57–2020–06–01 described 

previously, as incorporated by 

reference, except for any differences 

identified as exceptions in the 

regulatory text of this AD. 

Explanation of Required Compliance 

Information 

In the FAA’s ongoing efforts to 

improve the efficiency of the AD 


khammond on DSKJM1Z7X2PROD with PROPOSALS
Federal Register / Vol. 86, No. 110 / Thursday, June 10, 2021 / Proposed Rules 30821 

process, the FAA initially worked with 

Airbus and EASA to develop a process 

to use certain EASA ADs as the primary 

source of information for compliance 

with requirements for corresponding 

FAA ADs. The FAA has since 

coordinated with other manufacturers 

and civil aviation authorities (CAAs) to 

use this process. As a result, CAAI AD 

I–57–2020–06–01 will be incorporated 

by reference in the FAA final rule. This 

proposed AD would, therefore, require 

compliance with CAAI AD I–57–2020– 

06–01 in its entirety, through that 

incorporation, except for any differences 

identified as exceptions in the 

regulatory text of this proposed AD. 

Service information specified in CAAI 

AD I–57–2020–06–01 that is required 

for compliance with CAAI AD I–57– 

2020–06–01 will be available on the 

internet at https://www.regulations.gov 

by searching for and locating Docket No. 

FAA–2021–0459 after the FAA final 

rule is published. 

Costs of Compliance 

The FAA estimates that this proposed 

AD affects 23 airplanes of U.S. registry. 

The FAA estimates the following costs 

to comply with this proposed AD: 

ESTIMATED COSTS FOR REQUIRED ACTIONS

Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

80 work-hours × $85 per hour = $6,800 * ................................................................................... $400 * $7,200 * $165,600

* If the actions are accomplished during 4C Check. 

The FAA has received no definitive 

data on which to base the cost estimates 

for the repair specified in this proposed 

AD. 

According to the manufacturer, some 

or all of the costs of this proposed AD 

may be covered under warranty, thereby 

reducing the cost impact on affected 

oeprators. The FAA does not control 

warranty coverage for affected operators. 

As a result, the FAA has included all 

known costs in the 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. 

The FAA is 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 

The FAA 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) Would not affect intrastate 

aviation in Alaska, and 

(3) Would 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 adding 

the following new airworthiness 

directive: 

Gulfstream Aerospace LP: Docket No. FAA– 

2021–0459; Project Identifier MCAI– 

2021–00129–T. 

(a) Comments Due Date 

The FAA must receive comments on this 

airworthiness directive (AD) by July 26, 2021. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to Gulfstream Aerospace 

LP Model Gulfstream G280 airplanes, 

certificated in any category, as identified in 

The Civil Aviation Authority of Israel (CAAI) 

AD I–57–2020–06–01, dated January 27, 2021 

(CAAI AD I–57–2020–06–01). 

(d) Subject 

Air Transport Association (ATA) of 

America Code 57, Wings. 

(e) Reason 

This AD was prompted by a report that 

during full-scale fatigue testing, a crack was 

found in the area of the attachment of the 

wing rib 0 to the front spar. The FAA is 

issuing this AD to address any cracking at the 

area of the wing rib 0 to the front spar, which 

could affect the structural integrity of the 

wing. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Requirements 

Except as specified in paragraph (h) of this 

AD: Comply with all required actions and 

compliance times specified in, and in 

accordance with, CAAI AD I–57–2020–06– 

01. 

(h) Exceptions to CAAI AD I–57–2020–06–01 

Where CAAI AD I–57–2020–06–01 requires 

compliance ‘‘not later than 5,000 flight 

cycles,’’ this AD requires compliance before 

the accumulation of 5,000 total flight cycles 

since the date of issuance of the original 

Israeli airworthiness certificate or the date of 

issuance of the original Israeli export 

certificate of airworthiness. 

(i) No Reporting Requirement 

Although the service information 

referenced in CAAI AD I–57–2020–06–01 

specifies to submit certain information to the 

manufacturer, this AD does not include that 

requirement. 

(j) Other FAA AD Provisions 

The following provisions also apply to this 

AD:

supporting data. The FAA will consider 

all comments received by the closing 

date and may amend this proposal 

because of those comments. 

Except for Confidential Business 

Information (CBI) as described in the 

following paragraph, and other 

information as described in 14 CFR 

11.35, the FAA will post all comments 

received, without change, to https://

www.regulations.gov, including any 

personal information you provide. The 

agency will also post a report 

summarizing each substantive verbal 

contact received about this NPRM. 

Confidential Business Information 

CBI is commercial or financial 

information that is both customarily and 

actually treated as private by its owner. 

Under the Freedom of Information Act 

(FOIA) (5 U.S.C. 552), CBI is exempt 

from public disclosure. If your 

comments responsive to this NPRM 

contain commercial or financial 

information that is customarily treated 

as private, that you actually treat as 

private, and that is relevant or 

responsive to this NPRM, it is important 

that you clearly designate the submitted 

comments as CBI. Please mark each 

page of your submission containing CBI 

as ‘‘PROPIN.’’ The FAA will treat such 

marked submissions as confidential 

under the FOIA, and they will not be 

placed in the public docket of this 

NPRM. Submissions containing CBI 

should be sent to Kristi Bradley, 

Program Manager, COS Program 

Management Section, Operational 

Safety Branch, Compliance & 

Airworthiness Division, FAA, 10101 

Hillwood Pkwy., Fort Worth, TX 76177; 

telephone (817) 222–5110; email 

kristin.bradley@faa.gov. Any 

commentary that the FAA receives 

which is not specifically designated as 

CBI will be placed in the public docket 

for this rulemaking.
