SUPPLEMENTARY INFORMATION: 

Background 

The EASA, which is the Technical 

Agent for the Member States of the 

European Union, has issued EASA AD 

2020–0271, dated December 8, 2020 

(EASA AD 2020–0271) (also referred to 

as the Mandatory Continuing 

Airworthiness Information, or the 

MCAI), to correct an unsafe condition 

for Leonardo S.p.A. (formerly 

Finmeccanica S.p.A, AgustaWestland 

S.p.A., Agusta S.p.A.; and 

AgustaWestland Philadelphia 

Corporation, formerly Agusta Aerospace 

Corporation) Model AB139, AW139, 

and AW189 helicopters, all serial 

numbers. Although EASA AD 2020– 

0271 applies to Model AB139, AW139, 

and AW189 helicopters, all serial 

numbers, this AD applies to helicopters 

with an affected part installed instead. 

This AD was prompted by a report of 

the in-flight failure of one of the three 

stainless steel external rings bonded to 

the main rotor swashplate boot installed 

on Model AB139 and AW139 

helicopters. The broken ring, under the 

effects of the centrifugal force, was 

released from the main rotor swashplate 

boot and impacted one tail rotor blade, 

causing extensive damage. Investigation 

revealed that the failure of the external 

ring was caused by fatigue initiated by 

corrosion. A contributing factor to the 

external ring failure was disbonding at 

the four points where the affected ring 

was bonded to the main rotor 

swashplate boot. Leonardo S.p.a. Model 

AW189 helicopters have a similar 

design, therefore, this model may be 

subject to the same unsafe condition 

revealed on the Model AB139 and 

AW139 helicopters. Since EASA AD 

2020–0271 was published, there have 

been two more reports of discrepant 

main rotor boots. 

The FAA is issuing this AD to address 

corrosion, cracking, and damage to the 

adhesive (e.g., disbonding) of any 

stainless steel external ring bonded to 

the main rotor swashplate boot, which 

could result in release of a ring from the 

main rotor swashplate boot, resulting in 

damage to, and reduced control of, the 

helicopter. See the EASA AD for 

additional background information. 

Related IBR Material Under 1 CFR Part 

51 

EASA AD 2020–0271 specifies 

procedures for repetitive detailed 

inspections (DET) of the affected 

external rings for corrosion (including 

superficial oxidation), and cracks, and, 

depending on findings, polishing 

corrosion, and replacing an affected 

external ring with a serviceable part. 

EASA AD 2020–0271 also requires 

repetitive inspections for damage of the 

adhesive (e.g., disbonding) between the 

bonding areas of the affected external 

rings and the main rotor swashplate 

boot and re-applying the adhesive if 

necessary. For certain helicopters, 

EASA AD 2020–0271 requires a onetime restoring of the adhesive between 

the bonding areas of the affected 

external rings and the main rotor 

swashplate boot. For all helicopters, 

EASA AD 2020–0271 allows, under 

certain conditions, (re)installation of an 

affected part on a helicopter. 

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 

These products 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 of the unsafe condition 

described in the MCAI referenced 

above. The FAA is issuing this AD after 

evaluating all pertinent information and 

determining that the unsafe condition 

exists and is likely to exist or develop 

on other products of these same type 

designs. 

Requirements of This AD 

This AD requires accomplishing the 

actions specified in EASA AD 2020– 

0271, 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 

use this process. As a result, EASA AD 

2020–0271 is incorporated by reference 

in the FAA final rule. This AD would, 

therefore, require compliance with 

EASA AD 2020–0271 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 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 2020–0271 that is required for 

compliance with EASA AD 2020–0271 

is available on the internet at https://

www.regulations.gov by searching for 

and locating Docket No. FAA–2021– 

0512. 

FAA’s Justification and Determination 

of the Effective Date 

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

Administrative Procedure Act (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 providing notice and 

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. 

An unsafe condition exists that 

requires the immediate adoption of this 

AD without providing an opportunity 

for public comments prior to adoption. 

The FAA has found that the risk to the 

flying public justifies foregoing notice 

and comment prior to adoption of this 

rule because the in-flight failure of a 

stainless steel external ring bonded to 

the main rotor swashplate boot could 

result in damage to, and reduced control 

of, the helicopter. In addition, the 

compliance time for the required action 

is shorter than the time necessary for the 

public to comment and for publication 

of the final rule. Based on the average 

utilization rate for the affected Model 

AB139 and AW139 helicopters, it would 

take approximately one month for an 

affected helicopter to reach 25 hours 

time-in-service. Therefore, notice and 


lotter on DSK11XQN23PROD with RULES1
33500 Federal Register / Vol. 86, No. 120 / Friday, June 25, 2021 / Rules and Regulations 

opportunity for prior public comment 

are impracticable and contrary to public 

interest pursuant to 5 U.S.C. 

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

found good cause to forego notice and 

comment. 

Comments Invited 

The FAA invites you to send any 

written relevant data, views, or 

arguments about this AD. Send your 

comments to an address listed under 

ADDRESSES. Include ‘‘Docket No. FAA– 

2021–0512; Project Identifier MCAI– 

2020–01621–R’’ at the beginning of your 

comments. The most helpful comments 

reference a specific portion of the AD, 

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 AD 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 AD. 

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 Darren Gassetto, 

Aerospace Engineer, COS Program 

Management Section, Operational 

Safety Branch, Compliance & 

Airworthiness Division, FAA, 1600 

Stewart Ave., Suite 410, Westbury, NY 

11590; telephone (516) 228–7323; email 

Darren.Gassetto@faa.gov. 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 (RFA) 

The requirements of the 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 142 helicopters of U.S. registry. 

The FAA estimates the following costs 

to comply with this AD: 

ESTIMATED COSTS FOR REQUIRED ACTIONS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S.

Paperwork Reduction Act 

A federal agency may not conduct or 

sponsor, and a person is not required to 

respond to, nor shall a person be subject 

to penalty for failure to comply with a 

collection of information subject to the 

requirements of the Paperwork 

Reduction Act unless that collection of 

information displays a current valid 

OMB control number. The control 

number for the collection of information 

required by this AD is 2120–0056. The 

paperwork cost associated with this AD 

has been detailed in the Costs of 

Compliance section of this document 

and includes time for reviewing 

instructions, as well as completing and 

reviewing the collection of information. 

Therefore, all reporting associated with 

this AD is mandatory. Comments 

concerning the accuracy of this burden 

and suggestions for reducing the burden 

should be directed to Information 

Collection Clearance Officer, Federal 

Aviation Administration, 10101 

Hillwood Pkwy., Fort Worth, TX 76177– 

1524. 

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.

Federal Register / Vol. 86, No. 120 / Friday, June 25, 2021 / Rules and Regulations 33501 

Regulatory Findings 

The FAA determined that this AD 

would not have federalism implications 

under Executive Order 13132. This 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 regulation: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866, 

and 

(2) Will not affect intrastate aviation 

in Alaska. 

List of Subjects in 14 CFR Part 39
