SUPPLEMENTARY INFORMATION: 

Background 

EASA, which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA AD 2020–0242, 

dated November 5, 2020 (EASA AD 

2020–0242) (also referred to as the 

Mandatory Continuing Airworthiness 

Information, or the MCAI), to correct an 

unsafe condition for certain RRD Trent 

1000–A, Trent 1000–AE, Trent 1000–C, 

Trent 1000–CE, Trent 1000–D, Trent 

1000–E, Trent 1000–G, and Trent 

1000–H model turbofan engines. 

This AD was prompted by the 

manufacturer revising the engine TLM 

life limits of certain critical rotating 

parts and updating certain maintenance 

tasks. The FAA is issuing this AD to 

address the failure of critical rotating 

parts. 

FAA’s Determination 

These engines have been approved by 

the aviation authority of another 

country and are 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 about the unsafe condition 

described in the EASA AD referenced in 

this proposed AD. The FAA is issuing 

this AD because the agency evaluated 

all the relevant information provided by 

EASA and determined the unsafe 

condition described previously is likely 

to exist or develop in other products of 

the same type design. 

Related Service Information Under 1 

CFR Part 51 

The FAA reviewed EASA AD 2020– 

0242. EASA AD 2020–0242 specifies 

procedures for revising the approved 

AMP by incorporating the limitations, 

tasks, and associated thresholds and 

intervals described in the TLM. 

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 ADDRESSES. 

Other Related Service Information 

The FAA reviewed Chapter 05–10 of 

Rolls-Royce (RR) Trent 1000 TLM T– 

TRENT–10RRB, dated August 1, 2020. 

RR Trent 1000 TLM T–TRENT–10RRB, 

Chapter 05–10, identifies the reduced 

life limits of certain critical rotating 

parts. 

The FAA also reviewed Chapter 05– 

20 of RR Trent 1000 TLM T–TRENT– 

10RRB, dated August 1, 2020. RR Trent 

1000 TLM T–TRENT–10RRB, Chapter 

05–20, identifies the critical rotating 

part inspection thresholds and intervals. 

AD Requirements 

This AD requires accomplishing the 

actions specified in EASA AD 2020– 

0242, described previously, as 

incorporated by reference, except for 

any differences identified as exceptions 

in the regulatory text of this AD and 

except as discussed under ‘‘Differences 

Between this AD and the MCAI.’’ 

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 since coordinated 

with other manufacturers and civil 

aviation authorities (CAAs) to use this 

process. As a result, EASA AD 2020– 

0242 will be incorporated in this final 

rule. This AD, therefore, requires 

compliance with EASA AD 2020–0242 

in its entirety through that 

incorporation, except for any differences 

identified as exceptions in the 

regulatory text of this AD. Using 

common terms that are the same as the 

heading of a particular section in EASA 

AD 2020–0242 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 EASA AD 2020–0242. 

Service information required by EASA 

AD 2020–0242 for compliance will be 

available at https://www.regulations.gov 

by searching for and locating Docket No. 

FAA–2021–0879.

Federal Register / Vol. 86, No. 234 / Thursday, December 9, 2021 / Rules and Regulations 69989 

Differences Between This AD and the 

MCAI 

This AD does not mandate the 

‘‘Maintenance Tasks and Replacement 

of Critical Parts’’ and ‘‘Corrective 

Action(s)’’ sections of EASA AD 2020– 

0242. Where EASA AD 2020–0242 

requires compliance from its effective 

date, this AD requires using the effective 

date of this AD. Where EASA AD 2020– 

0242 requires revising the approved 

AMP within 12 months from its 

effective date, this AD requires revising 

the existing approved AMP within 90 

days after the effective date of this AD. 

This AD does not mandate compliance 

with the ‘‘Remarks’’ section of EASA 

AD 2020–0242. 

Justification for Immediate Adoption 

and Determination of the Effective Date 

Section 553(b)(3)(B) of the 

Administrative Procedure Act (APA) (5 

U.S.C. 551 et seq.) authorizes agencies 

to dispense with notice and comment 

procedures for rules when the agency, 

for ‘‘good cause’’ finds that those 

procedures are ‘‘impracticable, 

unnecessary, or contrary to the public 

interest.’’ Under this section, an agency, 

upon finding good cause, may issue a 

final rule without seeking comment 

prior to issuance. Further, section 

553(d) of the APA authorizes agencies to 

make rules effective in less than thirty 

days, upon a finding of good cause. 

The FAA justifies waiving notice and 

comment prior to adoption of this rule 

because no domestic operators use this 

product. It is unlikely that the FAA will 

receive any adverse comments or useful 

information about this AD from any U.S. 

operator. Accordingly, notice and 

opportunity for prior public comment 

are unnecessary, pursuant to 5 U.S.C. 

553(b)(3)(B). In addition, for the 

foregoing reason, the FAA finds that 

good cause exists pursuant to 5 U.S.C. 

553(d) for making this amendment 

effective in less than 30 days. 

Comments Invited 

The FAA invites you to send any 

written relevant data, views, or 

arguments about this final rule. Send 

your comments to an address listed 

under ADDRESSES. Include ‘‘Docket No. 

FAA–2021–0879; Project Identifier 

MCAI–2020–01494–E’’ at the beginning 

of your comments. The most helpful 

comments reference a specific portion of 

the final rule, explain the reason for any 

recommended change, and include 

supporting data. The FAA will consider 

all comments received by the closing 

date and may amend this final rule 

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 final rule. 

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 AD 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 AD, 

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 AD. Submissions containing CBI 

should be sent to Kevin M. Clark, 

Aviation Safety Engineer, ECO Branch, 

FAA, 1200 District Avenue, Burlington, 

MA 01803. Any commentary that the 

FAA receives that is not specifically 

designated as CBI will be placed in the 

public docket for this rulemaking. 

Regulatory Flexibility Act 

The requirements of the Regulatory 

Flexibility Act (RFA) do not apply when 

an agency finds good cause pursuant to 

5 U.S.C. 553 to adopt a rule without 

prior notice and comment. Because the 

FAA has determined that it has good 

cause to adopt this rule without notice 

and comment, RFA analysis is not 

required. 

Costs of Compliance 

The FAA estimates that this AD 

affects 0 engines installed on airplanes 

of U.S. registry. The FAA estimates the 

following costs to comply with this AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Revise the ALS of the AMP ............................ 1 work-hour × $85 per hour = $85 ................. $0 $85 $0 

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 

This AD will not have federalism 

implications under Executive Order 

13132. This AD will 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 this AD: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866, 

and 

(2) Will not affect intrastate aviation 

in Alaska.

Airworthiness Directives; Airbus 

Helicopters 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for all 

Airbus Helicopters Model AS355NP 

helicopters. This AD was prompted by 

a report of mechanical deformation 

found on the protective cover (also 

referred to as switch guard) of the 

‘‘SHEAR’’ control pushbutton installed 

on a co-pilot collective stick of a Model 

EC225LP helicopter, caused by incorrect 

handling; due to having an identical 

design switch guard installed on the 

pilot collective stick, Model AS355NP 

helicopters are also affected. This AD 

requires replacement of the protective 

cover of the ‘‘SHEAR’’ control 

pushbutton, and re-identification of the 

pilot collective stick, as specified in a 

European Union Aviation Safety Agency 

(EASA) AD, which is incorporated by 

reference. The FAA is issuing this AD 

to address the unsafe condition on these 

products. 

DATES: This AD is effective January 13, 

2022. 

The Director of the Federal Register
