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 

Safran Helicopter Engines, S.A. (Safran) 

Arriel 2D and Arriel 2E model 

turboshaft engines. This proposed AD 

was prompted by the manufacturer 

revising the maintenance and overhaul 

manuals to introduce new or more 

restrictive airworthiness limitations and 

maintenance tasks. This proposed AD 

would require the replacement of 

certain critical parts before reaching 

their published in-service life limits, 

performing scheduled maintenance 

tasks before reaching their published 

periodicity, and performing 

unscheduled maintenance tasks when 

the engine meets certain conditions. As 

a terminating action, this proposed AD 

would require operators to revise the 

airworthiness limitation section (ALS) 

of their existing approved aircraft 

maintenance program (AMP) by 

incorporating the revised airworthiness 

limitations and maintenance tasks. 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. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following 

methods:

Background 

The European Union Aviation Safety 

Agency (EASA), which is the Technical 

Agent for the Member States of the 

European Community, has issued EASA 

AD 2018–0273, dated December 13, 

2018 (referred to after this as ‘‘the 

MCAI’’), to address the unsafe condition 

on these products. The MCAI states: 

The airworthiness limitations and 

maintenance tasks for the SAFRAN ARRIEL 

2D, ARRIEL 2E and ARRIEL 2N engines, 

which are approved by EASA, are currently 

defined and published in the SAFRAN 

ARRIEL 2 Maintenance and Overhaul 

Manuals, as applicable. These instructions 

have been identified as mandatory for 

continued airworthiness. 

Failure to accomplish these instructions 

could result in an unsafe condition. 

SAFRAN recently revised the applicable 

Maintenance and Overhaul Manuals (the 

applicable ALS), introducing new and/or 

more restrictive airworthiness limitations 

and maintenance tasks. 

For the reason described above, this 

[EASA] AD requires accomplishment of the 

actions specified in the applicable ALS. 

You may obtain further information 

by examining the MCAI in the AD 

docket at https://www.regulations.gov 

by searching for and locating Docket No. 

FAA–2020–1038. 

FAA’s Determination 

The FAA is issuing this NPRM after 

determining that the unsafe condition 

described previously is likely to exist or 

develop on other products of the same 

type design. 

Related Service Information Under 1 

CFR Part 51 

The FAA reviewed Chapter 05–10–00 

of Safran Helicopter Engines ARRIEL 2D 

Maintenance Manual (MM) No. X292 R1 

450 2, Update No. 20, dated June 15, 

2020. Safran Helicopter Engines ARRIEL 

2D MM X292 R1 450 2 identifies the 

terms used in tables for limits and 

mandatory maintenance tasks, usage 

counters of the engine log book, life 

limits for life-limited parts, and 

mandatory inspection tasks to be carried 

out to reach the airworthiness objectives 

on Safran Arriel 2D model engines. 

The FAA reviewed Chapter 05–10–00 

of Safran Helicopter Engines ARRIEL 2E 

MM No. X292 R2 300 2, Update No. 16, 

dated June 15, 2020. Safran Helicopter 

Engines ARRIEL 2E MM X292 R2 300 2 

identifies the terms used in tables for 

limits and mandatory maintenance 

tasks, usage counters of the engine log 

book, life limits for life-limited parts, 

and mandatory inspection tasks to be 

carried out to reach the airworthiness 

objectives on Safran Arriel 2E model 

engines. 

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 ADDRESSES. 

Proposed AD Requirements in This 

NPRM 

This proposed AD would require the 

replacement of certain critical parts 

before reaching their published inservice life limits, performance of 

schedule maintenance tasks before 

reaching the published periodicity in 

the applicable Safran Arriel MM 

chapter, and performance of 

unscheduled maintenance tasks when 

the engine meets certain conditions 

specified in the applicable Safran Arriel 

MM chapter. As a terminating action, 

this proposed AD would require 

operators to revise the ALS of their 

existing approved AMP by 

incorporating the revised airworthiness 

limitations and maintenance tasks. 

Differences Between This Proposed AD 

and the MCAI 

The MCAI is applicable to Safran 

Arriel 2D, Arriel 2E, and Arriel 2N 

model turboshaft engines. This AD is 

only applicable to Safran Arriel 2D and 

2E model turboshaft engines. Safran 

Arriel 2N model turboshaft engines are 

not type certificated in the U.S. 

Costs of Compliance 

The FAA estimates that this AD, if 

adopted as proposed, would affect 426 

engines installed on helicopters of U.S. 

registry. 

The FAA estimates the following 

costs to comply with this proposed AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product

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 

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.

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
