SUPPLEMENTARY INFORMATION: 

Background 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to supersede AD 2020–21–01, 


TKELLEY on DSK125TN23PROD with RULES1
386 Federal Register / Vol. 87, No. 3 / Wednesday, January 5, 2022 / Rules and Regulations 

Amendment 39–21274 (85 FR 63440, 

October 8, 2020) (AD 2020–21–01). AD 

2020–21–01 applied to certain Airbus 

Helicopters Model AS–365N2, AS 

365N3, EC 155B, EC155B1, and SA– 

365N1 helicopters. The NPRM 

published in the Federal Register on 

September 30, 2021 (86 FR 54139). In 

the NPRM, the FAA proposed to 

continue to require modifying the MGB 

T/R drive flange installation, and also 

proposed to include additional 

helicopters in the applicability for the 

required actions. The NPRM was 

prompted by several reported 

occurrences of loss of tightening torque 

of the Shur-Lok nut, which serves as a 

retainer of the MGB T/R drive flange. 

EASA AD 2020–0287, dated 

December 21, 2020 (EASA AD 2020– 

0287), was issued by EASA, which is 

the Technical Agent for the Member 

States of the European Union, to correct 

an unsafe condition for certain AS 365 

N2, AS 365 N3, SA 365 C1, SA 365 C2, 

SA 365 C3, SA 365 N and SA 365 N1 

helicopters; and all EC 155 B and EC 

155 B1 helicopters. Model SA 365 C3 

helicopters 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 

helicopters in the applicability. EASA 

AD 2020–0287 supersedes EASA AD 

2020–0212, dated October 5, 2020, 

which required modification of the 

MGB T/R drive flange installation. 

EASA advises of reported occurrences 

of loss of tightening torque of the ShurLok nut, which serves as a retainer of 

the T/R drive flange of the MGB. EASA 

also advises of subsequent investigation 

that determined that these occurrences 

were the result of failure of the ShurLok nut locking function, which is 

normally ensured by two antirotation 

tabs engaged into two slots at the end of 

the MGB output shaft pinion. EASA 

states this condition could lead to the 

loosening of the Shur-Lok nut and 

disengagement of the Shur-Lok nut 

threads, possibly resulting in reduction 

of T/R drive control, rear transmission 

vibrations, and subsequent reduced 

control of the helicopter. 

Accordingly, EASA AD 2020–0287 

retains the modification of the MGB T/ 

R drive flange installation. EASA AD 

2020–0287 also includes additional 

helicopters in the applicability for the 

required actions (Model SA–365C1, SA– 

365C2, and SA–365N helicopters on 

which Airbus Helicopters modification 

0763B64 has been embodied; and Model 

EC 155B and EC155B1 helicopters 

without modification 0763B64 

embodied). 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received comments from 

three commenters. The commenters 

were an individual who made a 

statement about the applicability; an 

individual who expressed support and 

favor for the NPRM; and an anonymous 

commenter, who had a question about 

the applicability. The following presents 

the comments received on the NPRM 

and the FAA’s response to each 

comment. 

Request for Clarification of 

Applicability 

An individual stated the opinion that 

all helicopters should be subject to the 

same rules, a preference for unity under 

the law, and that it is unfair to have 

different rules for different helicopters. 

An anonymous commenter asked why 

the NPRM is only applicable to Airbus 

Helicopters and not other current and 

modern models of helicopters. The FAA 

infers that the commenters may be 

suggesting that this AD should apply to 

all helicopter models. No further 

justification was given. 

The FAA agrees to clarify the 

applicability. Each FAA AD has a 

specific applicability, and this FAA AD 

reflects the applicability of EASA AD 

2020–0287. This AD only addresses the 

models specified in the EASA AD that 

are affected by the unsafe condition. 

Helicopters and the systems that 

support the design are varied, and 

because of design variances between 

manufacturers, may or may not be 

subject to an unsafe condition. 

Therefore, in crafting a rule, the FAA 

specifically works to apply rulemaking 

only to the models and systems that are 

affected. Otherwise, the FAA may be 

creating arbitrary regulations, 

unnecessary work, and burdensome 

costs for the operators of the unaffected 

helicopters. There is no further need to 

expand the applicability of this AD to 

other helicopter models due to the 

likelihood that the type designs are 

different and therefore not subject to the 

unsafe condition. If information is 

received indicating other models are 

affected by the unsafe condition, the 

FAA will consider further rulemaking. 

The FAA has made no changes to this 

AD. 

Conclusion 

These helicopters have been approved 

by EASA and are approved for operation 

in the United States. Pursuant to the 

FAA’s bilateral agreement with the 

European Union, EASA has notified the 

FAA about the unsafe condition 

described in its AD. The FAA reviewed 

the relevant data, considered the 

comments received, and determined 

that air safety requires adopting this AD 

as proposed. Accordingly, the FAA is 

issuing this AD to address the unsafe 

condition on these helicopters. Except 

for minor editorial changes, this AD is 

adopted as proposed in the NPRM. 

None of the changes will increase the 

economic burden on any operator. 

Related Service Information Under 1 

CFR Part 51 

The FAA reviewed the following 

service information. 

Airbus Helicopters Alert Service 

Bulletin (ASB) No. AS365–63.00.26, 

Revision 0, dated July 22, 2020, for 

Model AS365N helicopters and non 

FAA-type certificated military Model 

AS365Fs helicopters; and Airbus 

Helicopters ASB No. SA365–65.52, 

Revision 1, dated July 22, 2020, for 

Model SA–365C1 and SA–365C2 

helicopters and non FAA-type 

certificated Model SA–365C3 

helicopters. This service information 

specifies procedures for modifying the 

MGB T/R drive flange installation, 

which include installing a rear (aft) 

output stop between the T/R drive 

flange and T/R drive shaft. These 

documents are distinct since they apply 

to different helicopter models. 

This AD also requires Airbus 

Helicopters ASB No. AS365–63.00.19, 

Revision 1, dated January 31, 2019; and 

Airbus Helicopters ASB No. EC155– 

63A013, Revision 1, dated January 31, 

2019; which the Director of the Federal 

Register approved for incorporation by 

reference as of November 12, 2020 (85 

FR 63440, October 8, 2020). 

This service information 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. 

Differences Between This AD and the 

EASA AD 

EASA AD 2020–0287 specifies 

compliance times of 600 flight hours or 

a certain time frame (months). However, 

this AD only requires the compliance 

time of 600 hours time-in-service. 

Costs of Compliance 

The FAA estimates that this AD 

affects 53 helicopters of U.S. Registry. 

Labor rates are estimated at $85 per 

work-hour. Based on these numbers, the 

FAA estimates the following costs to 

comply with this AD.

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, 

(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.

Federal Aviation Administration 

14 CFR Part 95 

[Docket No. 31408; Amdt. No. 563] 

IFR Altitudes; Miscellaneous 

Amendments 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: This amendment adopts 

miscellaneous amendments to the 

required IFR (instrument flight rules) 

altitudes and changeover points for 

certain Federal airways, jet routes, or 

direct routes for which a minimum or 

maximum en route authorized IFR 

altitude is prescribed. This regulatory 

action is needed because of changes 

occurring in the National Airspace 

System. These changes are designed to 

provide for the safe and efficient use of 

the navigable airspace under instrument 

conditions in the affected areas. 

DATES: Effective 0901 UTC, January 27, 

2022.

MacArthur Blvd., Registry Bldg 29 

Room 104, Oklahoma City, OK 73125. 

Telephone: (405) 954–4164. 

SUPPLEMENTARY INFORMATION: This 

amendment to part 95 of the Federal 

Aviation Regulations (14 CFR part 95) 

amends, suspends, or revokes IFR 

altitudes governing the operation of all 

aircraft in flight over a specified route 

or any portion of that route, as well as 

the changeover points (COPs) for 

Federal airways, jet routes, or direct 

routes as prescribed in part 95. 

The Rule 

The specified IFR altitudes, when 

used in conjunction with the prescribed 

changeover points for those routes, 

ensure navigation aid coverage that is 

adequate for safe flight operations and 

free of frequency interference. The 

reasons and circumstances that create 

the need for this amendment involve 

matters of flight safety and operational 

efficiency in the National Airspace 

System, are related to published 

aeronautical charts that are essential to 

the user, and provide for the safe and 

efficient use of the navigable airspace. 

In addition, those various reasons or 

circumstances require making this 

amendment effective before the next 

scheduled charting and publication date 

of the flight information to assure its 

timely availability to the user. The 

effective date of this amendment reflects 

those considerations. In view of the 

close and immediate relationship 

between these regulatory changes and 

safety in air commerce, I find that notice 

and public procedure before adopting 

this amendment are impracticable and 

contrary to the public interest and that 

good cause exists for making the 

amendment effective in less than 30 

days. 

Conclusion 

The FAA has determined that this 

regulation only involves an established 

body of technical regulations for which 

frequent and routine amendments are 

necessary to keep them operationally 

current. It, therefore—(1) is not a 

‘‘significant regulatory action’’ under 

Executive Order 12866; (2) is not a 

‘‘significant rule’’ under DOT 

Regulatory Policies and Procedures (44 

FR 11034; February 26, 1979); and (3) 

does not warrant preparation of a 

regulatory evaluation as the anticipated 

impact is so minimal. For the same 

reason, the FAA certifies that this 

amendment will not have a significant 

economic impact on a substantial 

number of small entities under the 

criteria of the Regulatory Flexibility Act.
