Airworthiness Directives; Leonardo 

S.p.a. 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 Leonardo S.p.a. Model A109E, 

A109S, and AW109SP helicopters. This 

proposed AD was prompted by reports 

of incorrect installation of the motor 

(MTR) cables and the bonding braids 

connected to the engine fire 

extinguisher bottles. This proposed AD 

would require inspecting the cables and 

bonding braids installation and, 

depending on the results, accomplishing 

corrective action, as specified in a 

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 NPRM by March 24, 2025. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following

Background 

EASA, which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA AD 2024–0193, 

dated October 11, 2024 (EASA AD 

2024–0193) (also referred to as the 

MCAI), to correct an unsafe condition 

on certain serial-numbered Leonardo 

S.p.a. Model A109E, A109LUH, A109S, 

and AW109SP helicopters. The MCAI 

states that reports were received of 

incorrect installation of the MTR cables 

and the bonding braids connected to the 

engine fire extinguisher bottles. This 

condition, if not detected and corrected, 

could lead to reduced performance of 

the engine fire extinguishing system 

during an engine fire and subsequent 

loss of control of the helicopter. The 

FAA is proposing this AD to address the 

unsafe condition on these products. 

You may examine the MCAI in the 

AD docket at regulations.gov under 

Docket No. FAA–2025–0020.

hand and right-hand side MTR cables 

and bonding braids for correct 

installation and, depending on the 

findings, accomplishing corrective 

action (disconnecting and properly 

reinstalling the affected MTR cable(s) 

and bonding braid(s)) in accordance 

with ‘‘the ASB’’ as defined within. 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 

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 is issuing this NPRM 

after determining that the unsafe 

condition described previously is likely 

to exist or develop on other products of 

these same type designs. 

Proposed AD Requirements in This 

NPRM 

This proposed AD would require 

accomplishing the actions specified in 

EASA AD 2024–0193, 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 the 

MCAI.’’ 

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 2024–0193 by 

reference in the FAA final rule. This 

proposed AD would, therefore, require 

compliance with EASA AD 2024–0193 

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 2024–0193 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 2024–0193. 

Material referenced in EASA AD 2024– 

0193 for compliance will be available at 

regulations.gov under Docket No. FAA– 

2025–0020 after the FAA final rule is 

published. 

Differences Between This Proposed AD 

and the MCAI 

EASA AD 2024–0193 applies to 

Model A109LUH helicopters; however, 

this proposed AD would not because 

that model is not FAA type-certificated. 

Costs of Compliance 

The FAA estimates that this AD, if 

adopted as proposed, would affect 101 

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 the proposed AD. 

Inspecting the engine fire extinguisher 

bottle electrical connections would take 

1 work-hour for an estimated cost of $85 

per helicopter and $8,585 for the U.S. 

fleet. 

Disconnecting and reinstalling the 

MTR cable(s) and bonding braid(s) 

would take up to 1 work-hour for an 

estimated cost of up to $85 per 

helicopter. 

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. 

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 

39 as follows: 

PART 39—AIRWORTHINESS 

DIRECTIVES 

■ 1. The authority citation for part 39 

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: 

Leonardo S.p.a.: Docket No. FAA–2025– 

0020; Project Identifier MCAI–2024– 

00604–R. 

(a) Comments Due Date 

The FAA must receive comments on this 

airworthiness directive (AD) by March 24, 

2025. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to Leonardo S.p.a. Model 

A109E, A109S, and AW109SP helicopters, 

certificated in any category, as identified in 

European Union Aviation Safety Agency AD 

2024–0193, dated October 11, 2024 (EASA 

AD 2024–0193). 

(d) Subject 

Joint Aircraft System Component (JASC) 

Code 2620, Extinguishing System. 

(e) Unsafe Condition 

This AD was prompted by reports of 

incorrect installation of the motor (MTR) 

cables and the bonding braids connected to 

the engine fire extinguisher bottles. The FAA 

is issuing this AD to detect and correct 

incorrect installation of the MTR cables and 

the bonding braids to the engine fire 

extinguisher bottles, which could lead to 

reduced performance of the engine fire 

extinguishing system during an engine fire 

and subsequent loss of control of the 

helicopter.
