AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA is superseding 

Airworthiness Directive (AD) 2021–08– 

02 for all Safran Helicopter Engines, 

S.A. (Safran) (type certificate previously 

held by Turbomeca, S.A.) Model Arriel 

2D and Arriel 2E engines. AD 2021–08– 

02 required replacing certain critical 

parts before reaching their published inservice life limits, performing scheduled 

maintenance tasks before reaching their 

published periodicity, and performing 

unscheduled maintenance tasks when 

the engine meets certain conditions. 

Since the FAA issued AD 2021–08–02, 

Safran has revised the airworthiness 

limitation section (ALS) of the existing 

maintenance and overhaul manuals, 

introducing new and more restrictive 

instructions and maintenance tasks, 

which prompted this AD action. This 

AD requires updating the ALS of the 

existing engine maintenance manual 

(EMM) or instructions for continued 

airworthiness (ICA) and the existing 

approved maintenance or inspection 

program, as applicable, by incorporating 

the actions and associated thresholds 

and intervals, including life limits, as 

specified in a European Union Aviation 

Safety Agency (EASA) AD, which is 

incorporated by reference. The FAA is 

proposing this AD to address the unsafe 

condition on these products. 

DATES: This AD is effective December 

26, 2023. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of December 26, 2023.

SUPPLEMENTARY INFORMATION: 

Background 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to supersede AD 2021–08–02, 

Amendment 39–21496 (86 FR 26651, 

May 17, 2021), (AD 2021–08–02). AD 

2021–08–02 applied to all Safran Model 

Arriel 2D and Arriel 2E engines. AD 

2021–08–02 required replacing 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, AD 2021–08–02 

required operators to revise the ALS of 

their existing approved aircraft 

maintenance program (AMP) by 

incorporating the revised airworthiness 

limitations and maintenance tasks. The 

FAA issued AD 2021–08–02 to prevent 

failure of the engine. 

The NPRM published in the Federal 

Register on October 31, 2022 (87 FR 

65535). The NPRM was prompted by 

EASA AD 2022–0083, dated May 11, 

2022 (EASA AD 2022–0083), issued by 

EASA, which is the Technical Agent for 

the Member States of the European 

Union (referred to after this as the 

MCAI), which supersedes EASA AD 

2018–0273, dated December 13, 2018 

(EASA AD 2018–0273). The MCAI states 

that the manufacturer published a 

revised ALS introducing new and more 

restrictive maintenance tasks and 

airworthiness limitations. These new or 

more restrictive maintenance tasks and 

airworthiness limitations include initial 

and repetitive inspections for clogging 

of the power turbine air pressurization 

pipe. 

You may examine the MCAI in the 

AD docket at regulations.gov under 

Docket No. FAA–2022–1311. 

In the NPRM, the FAA proposed to 

require revising the ALS of the 

operator’s existing approved 

maintenance or inspection program, as 

applicable, to incorporate new and more 

restrictive airworthiness limitations. 

The FAA issued a supplemental 

notice of proposed rulemaking (SNPRM) 

to amend 14 CFR part 39 to supersede 

AD 2021–08–02. The SNPRM published 

in the Federal Register on July 14, 2023 

(88 FR 45109). The SNPRM was 


ddrumheller on DSK120RN23PROD with RULES1
80578 Federal Register / Vol. 88, No. 222 / Monday, November 20, 2023 / Rules and Regulations 

prompted by the FAA’s determination 

that the NPRM contained an inaccurate 

reference to a certain paragraph of 

EASA AD 2022–0083 and that a reduced 

compliance time of 90 days is necessary. 

In the SNPRM, the FAA proposed to 

require revising the ALS of the existing 

EMM or ICA and the existing approved 

maintenance or inspection program, as 

applicable, to incorporate the actions 

specified in paragraph (1) of the MCAI, 

described previously, except as 

discussed under ‘‘Differences Between 

this AD and the MCAI.’’ The FAA is 

issuing this AD to address the unsafe 

condition on these products. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received no comments on 

the SNPRM or on the determination of 

the costs. 

Conclusion 

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 this 

State of Design Authority, it has notified 

the FAA of the unsafe condition 

described in the MCAI referenced 

above. The FAA reviewed the relevant 

data 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 

products. Except for minor editorial 

changes, this AD is adopted as proposed 

in the SNPRM. 

Related Service Information Under 1 

CFR Part 51 

The FAA reviewed EASA AD 2022– 

0083, which specifies instructions for 

accomplishing the actions specified in 

the applicable ALS, including 

performing maintenance tasks, replacing 

life-limited parts, and revising the 

existing approved AMP by 

incorporating the limitations, tasks, and 

associated thresholds and intervals 

described in the ALS. 

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 ADDRESSES. 

Differences Between This AD and the 

MCAI 

EASA AD 2022–0083 applies to Arriel 

2D, 2E, 2H, 2L2, and 2N model 

turboshaft engines, whereas this AD 

only applies to Model Arriel 2D and 

Arriel 2E engines. Arriel 2H, 2L2, and 

2N engines are not U.S. type 

certificated. 

Paragraph (1) of EASA AD 2022–0083 

specifies to replace each component 

before exceeding the applicable life 

limit and, within the thresholds and 

intervals, accomplishing all applicable 

maintenance tasks after its effective 

date. Instead, this AD requires revising 

the ALS of the existing EMM or ICA and 

the existing approved maintenance or 

inspection program, as applicable, by 

incorporating the requirements 

specified in paragraph (1) of EASA AD 

2022–0083 within 90 days after the 

effective date of this AD. 

Costs of Compliance 

The FAA estimates that this AD 

affects 426 engines installed on 

helicopters of U.S. Registry. The FAA 

estimates the following costs to comply 

with this 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 has determined that 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.
