Airworthiness Directives; Airbus 

Helicopters 

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 Helicopters Model SA– 

365N, SA–365N1, AS–365N2, AS 365 

N3, EC 155B, and EC155B1 helicopters. 

This proposed AD was prompted by the 

FAA’s determination that to improve 

the process and performance in 

collecting metal particles in the main 

gear box (MGB) certain existing 

magnetic plugs (electrical and nonelectrical) installed in the MGB pump 

intake must be replaced with improved 

non-electrical magnetic plugs. This 

proposed AD would require replacing 

the existing magnetic plug with an 

improved non-electrical magnetic plug, 

as specified in a European Aviation 

Safety Agency (now 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 January 14, 

2021.

Discussion 

The EASA, which is the Technical 

Agent for the Member States of the 

European Union, has issued EASA AD 

2018–0176, dated August 21, 2018 

(EASA AD 2018–0176) (also referred to 

as the Mandatory Continuing 

Airworthiness Information, or the 

MCAI), to correct an unsafe condition 

for certain Airbus Helicopters Model 

SA–365N, SA–365N1, AS–365N2, AS 

365 N3, EC 155B, and EC155B1 

helicopters. 

This proposed AD was prompted by 

the FAA’s determination that to 

improve the process and performance in 

collecting metal particles in the MGB 

certain existing magnetic plugs 

(electrical and non-electrical) installed 

in the MGB pump intake should be 

replaced with improved non-electrical 

magnetic plugs. The FAA is proposing 

this AD to address metal particles 

causing seizure of the MGB, loss of 

power to the main rotor, and subsequent 

loss of control of the helicopter. See the 

MCAI for additional background 

information. 

Related Service Information Under 1 

CFR Part 51 

EASA AD 2018–0176 describes 

procedures for replacing the existing 

magnetic plug (electrical and nonelectrical) installed in the MGB pump 

intake with an improved non-electrical 

magnetic plug. 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 

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 2018–0176, described 

previously, as incorporated by 

reference, except for any differences 

identified as exceptions in the 

regulatory text of this proposed 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 

2018–0176 will be incorporated by 

reference in the FAA final rule. This 

proposed AD would, therefore, require 

compliance with EASA AD 2018–0176 

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 

2018–0176 that is required for 

compliance with EASA AD 2018–0176 

will be available on the internet at 

https://www.regulations.gov by 

searching for and locating Docket No. 

FAA–2020–1036 after the FAA final 

rule is published. 

Interim Action 

The FAA considers this proposed AD 

interim action. If final action is later 

identified, the FAA might consider 

further rulemaking then. 

Costs of Compliance 

The FAA estimates that this proposed 

AD affects 52 helicopters 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 

Up to 7.5 work-hours × $85 per hour = 

$637.50.

$55 Up to $692.50 .......................................... Up to $36,010. 

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. 


TKELLEY on DSKBCP9HB2PROD with PROPOSALS
Federal Register / Vol. 85, No. 230 / Monday, November 30, 2020 / Proposed Rules 76497 

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. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Incorporation by reference, 

Safety. 

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 14 CFR part

determination that to improve the process 

and performance in collecting metal particles 

in MGB certain existing magnetic plugs 

(electrical and non-electrical) installed in the 

MGB pump intake must be replaced with 

improved non-electrical magnetic plugs. The 

FAA is issuing this AD to address metal 

particles causing seizure of the MGB, loss of 

power to the main rotor, and subsequent loss 

of control of the helicopter. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Requirements 

Except as specified in paragraph (h) of this 

AD: Comply with all required actions and

to discard certain parts, this AD does not 

include that requirement. 

(4) Where EASA AD 2018–0176 refers to 

flight hours (FH), this AD requires using 

hours time-in-service. 

(i) Special Flight Permit 

Special flight permits may be issued in 

accordance with 14 CFR 21.197 and 21.199 

to operate the helicopter to a location where 

the helicopter can be modified (if the 

operator elects to do so), provided the 

helicopter is operated using day visual flight 

rules and no passengers are onboard.
