Department of Energy 

For the reasons set forth in the 

preamble, DOE proposes to amend part 

430 of chapter II, subchapter D, of title 

10 of the Code of Federal Regulations, 

as set forth below: 

PART 430—ENERGY CONSERVATION 

PROGRAM FOR CONSUMER 

PRODUCTS 

■ 1. The authority citation for part 430 

continues to read as follows: 

Authority: 42 U.S.C. 6291–6309; 28 U.S.C. 

2461 note. 

■ 2. Amend § 430.2 by: 

■ (a) Revising the definition for 

‘‘Circulating water heater;’’ and 

■ (b) Adding in alphabetical order, the 

definitions for ‘‘Electric circulating 

water heater,’’ ‘‘Gas-fired circulating 

water heater,’’ and ‘‘Oil-fired circulating 

water heater.’’ 

The revision and additions read as 

follows: 

§ 430.2 Definitions. 

* * * * * 

Circulating water heater means a 

water heater that does not have an 

operational scheme in which the burner, 

heating element, or compressor initiates 

and/or terminates heating based on 

sensing flow; has a water temperature 

sensor located at the inlet or the outlet 

of the water heater or in a separate 

storage tank that is the primary means 

of initiating and terminating heating; 

and must be used in combination with 

a recirculating pump to circulate water 

and either a separate storage tank or 

water circulation loop in order to 

achieve the water flow and temperature 

conditions recommended in the 

manufacturer’s installation and 

operation instructions. Paired with a 

separate storage tank, a circulating water 

heater constitutes a storage-type water 

heater. 

* * * * * 

Electric circulating water heater 

means a circulating water heater with an 

input of 12 kW or less; contains more 

than one gallon of water per 4,000 Btu/ 

h of input (including heat pump-only 

units with power inputs of no more than 

24 A at 250 V). 

* * * * * 

Gas-fired circulating water heater 

means a circulating water heater with a 

nominal input of 75,000 Btu/h or less; 

contains more than one gallon of water 

per 4,000 Btu/h of input. 

* * * * * 

Oil-fired circulating water heater 

means a circulating water heater with a 

nominal input of 105,000 Btu/h or less; 

contains more than one gallon of water 

per 4,000 Btu/h of input.

Airworthiness Directives; BAE 

Systems (Operations) Limited 

Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to 

supersede Airworthiness Directive (AD) 

2022–25–18, which applies to certain 

BAE Systems (Operations) Limited 

Model BAe 146 and Model Avro 146– 

RJ series airplanes. AD 2022–25–18 

requires repetitive inspections for 

cracking of the main landing gear (MLG) 

side stay outer link and replacement if 

necessary. Since the FAA issued AD 

2022–25–18, additional investigations of 

the causes of the cracking were 

conducted. This proposed AD would 

require a reduction of the repetitive 

visual inspection interval, provide 

optional repetitive special detailed 

inspections, accomplishing a one-off 

dimensional tolerance check and 

performing a repetitive lubrication of 

the MLG side stay outer link pivot, as 

specified in a United Kingdom (U.K.) 

Civil Aviation Authority (CAA) (U.K. 

CAA) AD, which is proposed for 

incorporation by reference (IBR). The 

FAA is proposing this AD to address the 

unsafe condition on these products. 

DATES: The FAA must receive comments 

on this proposed AD by February 12, 

2024. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following 

methods:

Background 

The FAA issued AD 2022–25–18, 

Amendment 39–22274 (87 FR 75915, 

December 12, 2022; corrected December 

27, 2022 (87 FR 79236)) (AD 2022–25– 

18), for certain BAE Systems 

(Operations) Limited Model BAe 146 

and Model Avro 146–RJ series airplanes. 

AD 2022–25–18 was prompted by an 

MCAI originated by the U.K. CAA, 

which is the aviation authority for the 

United Kingdom. U.K. CAA issued AD 

G–2022–0018, dated October 18, 2022, 

to correct an unsafe condition. 

AD 2022–25–18 requires repetitive 

inspections for cracking of the MLG side 

stay outer link and replacement if 

necessary. The FAA issued AD 2022– 

25–18 to address cracking on the 

shoulders of a MLG side stay outer link. 

The unsafe condition, if not addressed, 

could lead to failure of the MLG side 

stay outer link and MLG collapse, which 

could result in a runway departure and 

the engine or wing contacting the 

ground. The engine or wing contacting 

the ground could result in damage to the 

airplane, an increased risk of fire, the 

airplane flipping, and injury to 

occupants. 

Actions Since AD 2022–25–18 Was 

Issued 

Since the FAA issued AD 2022–25– 

18, U.K. CAA superseded AD G–2022– 

0018, dated October 18, 2022, and 

issued AD G–2023–0004R1, dated 

November 16, 2023 (U.K. CAA AD G– 

2023–004R1) (also referred to as the 

MCAI), to correct an unsafe condition 

for all BAE Systems (Operations) 

Limited Model BAe 146–301, BAe 146– 

100A, –200A, and –300A airplanes and 

Model Avro 146–RJ70A, 146–RJ85A, 

146–RJ100A. Model BAe 146–301 

airplanes are not certificated by the FAA 

and are not included on the U.S. type 

certificate data sheet; this AD therefore 

does not include those airplanes in the 

applicability. The MCAI states that 

further investigation resulted in a 

reduced repetitive detailed visual 

inspection interval and an option to do 

repetitive special detailed inspections; a 

new requirement for a one-time 

dimensional tolerance check; and a 

requirement to perform a repetitive 

lubrication of the MLG side stay outer 

link pivot. 

The FAA is proposing this AD to 

address cracking of the MLG side stay 

outer link. The unsafe condition, could 

lead to failure of the MLG side stay 

outer link and MLG collapse, which 

could result in a runway departure and 

the engine or wing contacting the 

ground. The engine or wing contacting 

the ground could result in damage to the 

airplane, an increased risk of fire, the 

airplane flipping, and injury to 

occupants. You may examine the MCAI 

in the AD docket at regulations.gov 

under Docket No. FAA–2023–2400. 

Related Service Information Under 1 

CFR Part 51 

U.K. CAA AD G–2023–004R1 

specifies procedures for doing repetitive 

detailed visual inspections or special 

detailed inspections for cracking of the 

MLG side stay outer link and 

replacement if necessary; a one-time 

dimensional tolerance check of the MLG 

side stay outer link and corrective 

actions including replacement if 

necessary: and repetitive lubrication of 

the MLG side stay outer link pivot. 

The FAA reviewed BAE Systems 

(Operations) Limited Alert Service 

Bulletin (ASB) ASB.32–A189, Revision 

2, dated August 3, 2023. This service 

information describes procedures for 

doing, among other actions, detailed 

visual inspections and special detailed 

inspections (fluorescent dye penetrant) 

for cracking of the MLG side stay outer 

link, replacement of the side stay outer 

link; a one-time dimensional tolerance 

check of the MLG side stay outer link; 

removing the side stay outer link and 

contacting the manufacturer; reapplying protective treatment/paint; and 

lubrication of the MLG side stay outer 

link pivot. 

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 

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 this State of 

Design Authority, it has notified the 

FAA of the unsafe condition described 

in the MCAI and service information 

referenced above. The FAA is issuing 

this NPRM after determining that the 

unsafe condition described previously is 

likely to exist or develop in other 

products of the same type design. 

Proposed AD Requirements in This 

NPRM 

This proposed AD requires 

accomplishing the actions specified in 

U.K. CAA AD G–2023–0004R1 

described previously, except for any 

differences identified as exceptions in 

the regulatory text of this proposed AD. 

Interim Action 

The FAA considers that this proposed 

AD would be an interim action. If final 

action is later identified, the FAA might 

consider further rulemaking then.

Federal Register / Vol. 88, No. 247 / Wednesday, December 27, 2023 / Proposed Rules 89341 

Explanation of Required Compliance 

Information 

In the FAA’s ongoing efforts to 

improve the efficiency of the AD 

process, the FAA developed a process to 

use some civil aviation authority (CAA) 

ADs as the primary source of 

information for compliance with 

requirements for corresponding FAA 

ADs. The FAA has been coordinating 

this process with manufacturers and 

CAAs. As a result, the FAA proposes to 

incorporate U.K. CAA AD G–2023– 

004R1 by reference in the FAA final 

rule. This proposed AD would, 

therefore, require compliance with U.K. 

CAA AD G–2023–004R1 in its entirety 

through that incorporation, except for 

any differences identified as exceptions 

in the regulatory text of this proposed 

AD. Service information required by 

U.K. CAA AD G–2023–004R1 for 

compliance will be available at 

regulations.gov under Docket No. FAA– 

2023–2400 after the FAA final rule is 

published. 

Costs of Compliance 

The FAA estimates that this AD, if 

adopted as proposed, would affect 20 

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 

2 work-hours × $85 per hour = $170 .......................................................................................... $0 $170 $3,400 

ESTIMATED COSTS FOR ON-CONDITION ACTIONS

Labor cost Parts cost Cost per product 

Up to 5 work-hours × $85 per hour = Up to $425 .................................. Up to $3,000 .................................. Up to $3,425. 

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:
