10498 Federal Register / Vol. 86, No. 33 / Monday, February 22, 2021 / Proposed Rules 

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

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: 

General Electric Company: Docket No. FAA– 

2020–1179; Project Identifier AD–2020– 

00818–E.

Code 7250, Turbine Section. 

(e) Unsafe Condition 

This AD was prompted by an inspection by 

the manufacturer that revealed cracking of 

the high-pressure turbine (HPT) rotor stage 1 

disk, caused by initial flange-to-flange 

cracking on the HPT thermal shield between 

the HPT rotor stage 1 disk and the HPT rotor 

stage 2 disk. The FAA is issuing this AD to 

prevent failure of the HPT rotor stage 1 disk 

and the HPT rotor stage 2 disk. The unsafe 

condition, if not addressed, could result in 

uncontained release of the HPT rotor stage 1 

and stage 2 disks, damage to the engine, and 

damage to the airplane. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Required Actions 

(1) After the effective date of this AD, at 

every piece-part exposure of the HPT rotor 

stage 1 disk, HPT rotor stage 2 disk, or the 

HPT thermal shield, perform a visual 

inspection and a fluorescent penetrant 

inspection (FPI) of the HPT thermal shield. 

(2) During any inspection required by 

paragraph (g)(1) of this AD, if a crack 

extending through either the forward or aft 

flange of the HPT thermal shield is detected, 

remove the HPT thermal shield, the HPT 

rotor stage 1 disk, and the HPT rotor stage 2 

disk from service. 

(h) Installation Prohibition 

Do not install onto any engine an HPT 

rotor stage 1 disk or HPT rotor stage 2 disk 

that was removed from service due to the 

requirements of paragraph (g)(2) of this AD. 

(i) Definition 

For the purpose of this AD, ‘‘piece-part 

exposure’’ is when the HPT rotor stage 1 

disk, HPT rotor stage 2 disk, or HPT thermal 

shield is separated from their mating rotor 

parts within the HPT rotor module. 

(j) Alternative Methods of Compliance 

(AMOCs) 

(1) The Manager, ECO Branch, FAA, has 

the authority to approve AMOCs for this AD, 

if requested using the procedures found in 14 

CFR 39.19. In accordance with 14 CFR 39.19,

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to adopt a 

new airworthiness directive (AD) for 

certain Airbus SAS Model A330–200 

Freighter series airplanes. This 

proposed AD was prompted by a report 

indicating occurrences of broken 

brackets of the support structure of the 

halon fire extinguishing bottle 4005WX; 

investigation showed that fatigue cracks 

initiated in the attachment brackets at 

the cross beams due to dynamic loading, 

and in some cases propagated in the 

struts. This proposed AD would require 

replacing the support brackets of the 

4005WX fire extinguisher bottle with 

reinforced support brackets, and 

replacing the strut assembly at the 

affected location, as specified in a 

European Union Aviation Safety Agency 

(EASA) AD, which is proposed for 

incorporation by reference. 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 April 8, 2021.

Discussion 

The EASA, which is the Technical 

Agent for the Member States of the 

European Union, has issued EASA AD 

2020–0234, dated October 27, 2020 

(EASA AD 2020–0234) (also referred to 

as the Mandatory Continuing 

Airworthiness Information, or the 

MCAI), to correct an unsafe condition 

for certain Airbus SAS Model A330–200 

Freighter series airplanes. 

This proposed AD was prompted by 

a report indicating occurrences of 

broken brackets of the support structure 

of the halon fire extinguishing bottle 

4005WX; investigation showed that 

fatigue cracks initiated in the 

attachment brackets at the cross beams 

due to dynamic loading, and in some 

cases propagated in the struts. The FAA 

is proposing this AD to address fatigue 

cracking on the attachment brackets, 

which could lead to damage of the 

tubing and electrical wiring of the lower 

deck cargo compartment (LDCC) fire 

extinguishing system, and possibly 

result in insufficient fire suppression 

capability in the LDCC. See the MCAI 

for additional background information. 

Related Service Information Under 1 

CFR Part 51 

EASA AD 2020–0234 describes 

procedures for replacing the support 

brackets of the 4005WX fire 

extinguisher bottle with reinforced 

support brackets, and replacing the strut 

assembly at the right-hand underfloor 

section 13/14 at frame (FR) 34/35 and 

FR35/36. 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 

EASA AD 2020–0234 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 

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 


tkelley on DSKBCP9HB2PROD with PROPOSALS
10500 Federal Register / Vol. 86, No. 33 / Monday, February 22, 2021 / Proposed Rules 

use this process. As a result, EASA AD 

2020–0234 will be incorporated by 

reference in the FAA final rule. This 

proposed AD would, therefore, require 

compliance with EASA AD 2020–0234 

in its entirety, through that 

incorporation, except for any differences 

identified as exceptions in the 

regulatory text of this proposed AD. 

Using common terms that are the same 

as the heading of a particular section in 

the EASA AD does not mean that 

operators need comply only with that 

section. For example, where the AD 

requirement refers to ‘‘all required 

actions and compliance times,’’ 

compliance with this AD requirement is 

not limited to the section titled 

‘‘Required Action(s) and Compliance 

Time(s)’’ in the EASA AD. Service 

information specified in EASA AD 

2020–0234 that is required for 

compliance with EASA AD 2020–0234 

will be available on the internet at 

https://www.regulations.gov by 

searching for and locating Docket No. 

FAA–2021–0014 after the FAA final 

rule is published. 

Costs of Compliance 

The FAA estimates that this proposed 

AD affects 6 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 

14 work-hours × $85 per hour = $1,190 ..................................................................................... $1,900 $3,090 $18,540

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 

individuals. The FAA does not control 

warranty coverage for affected 

individuals. 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) Will not affect intrastate aviation 

in Alaska, and 

(3) 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.

SUMMARY: The FAA proposes to adopt a 

new airworthiness directive (AD) for 

certain Safran Helicopter Engines, S.A. 

(Safran Helicopter Engines) Arriel 2B, 

2B1, 2C, 2C1, 2C2, 2S1 and 2S2 model 

turboshaft engines. This proposed AD 

was prompted by reports of nonconforming fuel filter pre-blockage 

pressure switches. This proposed AD 

would require repetitive visual 

inspections of the fuel filter by-pass 

indicator pop-up, a one-time operational 

test of the fuel filter pre-blockage 

pressure switch and, depending on the 

findings, replacement of the fuel filter 

pre-blockage pressure switch with a part
