AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to adopt a 

new airworthiness directive (AD) for all 

Airbus Helicopters Model AS–365N2, 

AS 365 N3, EC 155B, EC155B1, and SA– 

365N1 helicopters. This proposed AD 

was prompted by a large amount of 

critical scale particles found on the tail 

rotor gearbox (TGB) chip detector 

magnetic plug during an unscheduled 

check of the TGB. The particles 

belonged to the double bearing (pitch 

control rod bearing) installed inside the 

TGB. This proposed AD would require 

repetitive inspections of the TGB chip 

detector for particles, analyzing any 

particles collected, performing a double 

bearing washing, repetitive 

replacements of certain part-numbered

Background 

EASA, which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA AD 2021–0170, 

dated July 19, 2021 (EASA AD 2021– 

0170), to correct an unsafe condition for 

all Airbus Helicopters (AH), formerly 

Eurocopter, Eurocopter France, 

Aerospatiale, Sud Aviation, Model AS 

365 N2, AS 365 N3, EC 155 B, EC 155 

B1 and SA 365 N1 helicopters. 

This proposed AD was prompted by 

a large amount of critical scale particles 

found on the TGB chip detector 

magnetic plug during an unscheduled 

check of a Model AS 365 N2 helicopter. 

EASA advises the particles belonged to 

the double bearing (pitch control rod 

bearing) installed inside the TGB and 

further advises the reported event 

showed a speed of degradation faster 

than expected. The FAA is proposing 

this AD to prevent bearing degradation 

and subsequent failure, which could 

result in loss of yaw control. See EASA 

AD 2021–0170 for additional 

background information. 

Related Service Information Under 1 

CFR Part 51 

EASA AD 2021–0170 requires 

analyzing any particles collected during 

close monitoring or during any required 

inspections, repetitive inspections of the 

TGB chip detector for particles, 

performing a double bearing washing, 

and corrective actions. Corrective 

actions include removing an affected 

TGB and repairing or replacing that 

TGB, sending affected parts and certain 

information to the manufacturer, 

replacing a TGB chip detector or TGB 

electrical magnetic plug, and replacing 

an affected O-ring and double bearing. 

EASA AD 2021–0170 also requires 

performing a double bearing washing or 

performing a metallurgical analysis 

based on inspection results. 

EASA AD 2021–0170 also requires for 

any double bearing part number (P/N) 

704A33–651–245 or 704A33–651–246, 

installed on any TGB P/N 365A33– 

6005–09, before exceeding 610 flight 

hours (FH) since first installation, or 

within 110 FH after October 28, 2019 

(the effective date of EASA AD 2019– 

0267–E, dated October 25, 2019), 

whichever occurs later, and thereafter at 

intervals not to exceed 500 FH, 

replacing the affected double bearing 

with a serviceable one. EASA AD 2021– 

0170 allows double bearing part number 

P/N 704A33–651–245 or 704A33–651– 

246 to be installed, provided it has 

never been installed on a helicopter and 

it is inspected as required by EASA AD 

2021–0170. Finally, EASA AD 2021– 

0170 allows TGB P/N 365A33–6005–09 

to be installed, provided it has a 

serviceable double bearing installed that 

is inspected as required by the EASA 

AD.

Other Related Service Information 

The FAA reviewed Airbus Helicopters 

Emergency Alert Service Bulletin 

(EASB) No. 01.00.24 for non FAA-type 

certificated military Model AS565MA, 

MB, MBe, SA, SB, and UB helicopters; 

EASB No. 01.00.71 for Model AS365N1, 

N2, and N3 helicopters, and non FAAtype certificated military Model 

AS365F, Fi, K, and K2 helicopters; 

EASB No. 01.31 for non FAA-type 

certificated military Model SA366GA 

helicopters; and EASB No. 04A016 for 

Model EC155B and B1 helicopters, each 

Revision 3 and dated June 14, 2021 (copublished as one document). 

This service information specifies 

procedures to inspect the TGB chip 

detector for particles, analyze and 

define the particles by performing a 

metallurgical analysis, perform a 

washing of the double bearing, replace 

the double bearing, and send certain 

information and affected parts to the 

manufacturer. 

FAA’s Determination 

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 is 

proposing this AD after evaluating all 

known relevant information and 

determining that the unsafe condition 

described previously is likely to exist or 

develop on other helicopters of the same 

type design. 

Proposed AD Requirements in This 

NPRM 

This proposed AD would require 

accomplishing the actions specified in 

EASA AD 2021–0170, described 

previously, as incorporated by 

reference, except for any differences 

identified as exceptions in the 

regulatory text of this proposed AD and 

except as discussed under ‘‘Differences 

Between this Proposed AD and EASA 

AD 2021–0170.’’ 

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 EASA AD 2021–0170 by 

reference in the FAA final rule. This 

proposed AD would, therefore, require 

compliance with EASA AD 2021–0170 

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 

EASA AD 2021–0170 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 2021–0170. 

Service information referenced in EASA 

AD 2021–0170 for compliance will be 

available at https://www.regulations.gov 

by searching for and locating Docket No. 

FAA–2022–0295 after the FAA final 

rule is published. 

Differences Between This Proposed AD 

and EASA AD 2021–0170 

Service information referenced in 

EASA AD 2021–0170 specifies sending 

compliance forms, and certain parts to 

the manufacturer; this proposed AD 

would not. Service information 

referenced in EASA AD 2021–0170 

specifies contacting Airbus Helicopters 

for approved repairs or corrective 

actions if certain discrepancies are 

found, whereas this proposed AD would 

require accomplishing repairs or 

corrective actions using a method 

approved by the Manager, General 

Aviation and Rotorcraft Section, 

International Validation Branch, FAA; 

or EASA; or Airbus Helicopters’ EASA 

Design Organization Approval (DOA). If 

approved by the DOA, the approval 

must include the DOA-authorized 

signature. 

Interim Action 

The FAA considers this proposed AD 

would be an interim action. If final 

action is later identified, the FAA might 

consider further rulemaking. 

Costs of Compliance 

The FAA estimates that this AD, if 

adopted as proposed, would affect 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 proposed AD. 

Analyzing any particles collected 

during close monitoring would take 

about 1 work-hour for an estimated cost 

of $85 per inspection and up to $4,505 

for the U.S. fleet. 

Replacing a double bearing would 

take about 16 work-hours and parts cost 

about $1,620 for an estimated cost of 

2,980 per replacement and $157,940 for 

the U.S. fleet. 

Inspecting the TGB chip detector for 

particles would take about 1 work-hour 

for an estimated cost of $85 per 

inspection and $4,505 for the U.S. fleet. 

Performing a double bearing washing 

would take about 8 work-hours for an 

estimated cost of $680 per helicopter. 

The FAA estimates the following 

costs to do any necessary on-condition 

replacements that would be required 

based on the results of the inspection. 

The agency has no way of determining 

the number of aircraft that might need 

these on-condition replacements: 

Analyzing collected particles would 

take about 1 work-hour for an estimated 

cost of $85 per helicopter. 

Replacing a double bearing would 

take about 16 work-hours and parts 

would cost about $1,620 for an 

estimated cost of $2,980 per bearing. 

Replacing a TGB chip detector or TGB 

electrical magnetic plug would take 

about 1 work-hour and parts would cost 

about $900 for an estimated cost of $985 

per part replacement. 

Replacing an O-ring would take about 

1 work-hour and parts would cost about 

$100 for an estimated cost of $185 per 

O-ring. 

Replacing a TGB would take about 8 

work-hours and parts would cost about 

$155,302 for an estimated cost of 

$155,982 per replacement. 

The FAA has received no definitive 

data for the repair cost of a TGB. 

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. 87, No. 69 / Monday, April 11, 2022 / Proposed Rules 21055 

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.

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: 

Airbus Helicopters: Docket No. FAA–2022– 

0295; Project Identifier MCAI–2021– 

00840–R. 

(a) Comments Due Date 

The FAA must receive comments on this 

airworthiness directive (AD) by May 26, 

2022. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to all Airbus Helicopters 

Model AS–365N2, AS 365 N3, EC 155B, 

EC155B1, and SA–365N1 helicopters, 

certificated in any category. 

(d) Subject 

Joint Aircraft Service Component (JASC)

(e) Unsafe Condition 

This AD was prompted by a large amount 

of critical scale particles found on the tail 

rotor gearbox (TGB) chip detector magnetic 

plug during an unscheduled check of the 

TGB. The particles belonged to the double 

bearing (pitch control rod bearing) installed 

inside the TGB. The FAA is issuing this AD 

to prevent bearing degradation and 

subsequent failure. The unsafe condition, if 

not addressed, could result in loss of yaw 

control of the helicopter.

(iii) The effective date of EASA AD 2021– 

0170. 

(3) Where EASA AD 2021–0170 requires 

actions during each ‘‘after last flight (ALF) of 

the day inspection’’ or ‘‘ALF,’’ this AD 

requires those actions before the first flight of 

each day. 

(4) Where paragraph (7) of EASA AD 2021– 

0170 specifies ‘‘any discrepancy,’’ for this AD 

discrepancies include the presence of 

particles and other conditions such as 

abrasions, particles that consist of any scale, 

chip, flake, splinter, M50 particles, magnetic 

abrasion dust, or other particles other than 

cotter pin fragments, pieces of lock wire, 

swarf, or miscellaneous non-metallic waste. 

(5) Where paragraph (8) of EASA AD 2021– 

0170 specifies for Group 2 helicopters, the 

first replacement of the affected part must be 

accomplished not later than December 31,

helicopters, the first replacement of the 

affected part as defined in EASA AD 2021– 

0170 must be accomplished within 5 months 

after the effective date of this AD. 

(6) Where any work card referenced in the 

service information referenced in EASA AD 

2021–0170 specifies ‘‘if there is an anomaly, 

replace the chip detector,’’ or ‘‘if there is an 

anomaly, replace the TGB electrical magnetic 

plug,’’ for this AD an anomaly may be 

indicated by the magnetic component of the 

TGB chip detector or the TGB electrical 

magnetic plug not being magnetized. If there 

is an anomaly, this AD requires before further 

flight, removing from service the TGB chip 

detector or the TGB electrical magnetic plug 

as applicable to your model helicopter. 

(7) Where any work card referenced in the 

service information referenced in EASA AD 

2021–0170 specifies ‘‘make sure that the chip

helicopter, for this AD ‘‘good condition’’ is 

indicated when there are no signs of wear on 

the locking systems (including wear on the 

bayonets, and slotted tubes). If there are any 

signs of wear on the locking systems, this AD 

requires before further flight, removing from 

service the TGB chip detector or the TGB 

magnetic electrical magnetic plug as 

applicable to your model helicopter.

section, the FAA is charged with 

prescribing regulations to assign the use 

of airspace necessary to ensure the 

safety of aircraft and the efficient use of 

airspace. This regulation is within the 

scope of that authority, as it would 

modify Class D and Class E airspace, 

and establish Class E airspace at Oxnard 

Airport, to support IFR operations at the 

airport.
