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 

helicopters. This proposed AD was 

prompted by reports that certain tail 

rotor gearbox assemblies were installed 

on Model A109E helicopters and those 

parts are not approved for installation 

on that helicopter model. Because those 

assemblies are not part of the type 

design for Model A109E helicopters, 

there are no overhaul or life limits 

included in the applicable maintenance 

manuals. This proposed AD would 

require replacement of each affected tail 

rotor gearbox assembly with a 

serviceable part, as specified in a 

European Union Aviation Safety Agency 

(EASA) AD, which is proposed for 

incorporation by reference (IBR). 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 October 12, 

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 

EASA, which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA AD 2021–0031, 

dated January 22, 2021 (EASA AD 

2021–0031), to correct an unsafe 

condition for Leonardo S.p.A., formerly 

Finmeccanica S.p.A., AgustaWestland 

S.p.A., and Agusta S.p.A., Model A109E 

helicopters, all serial numbers up to 

11160 inclusive. 


khammond on DSKJM1Z7X2PROD with PROPOSALS
47428 Federal Register / Vol. 86, No. 162 / Wednesday, August 25, 2021 / Proposed Rules 

This proposed AD was prompted by 

reports that certain tail rotor gearbox 

assemblies were installed on Model 

A109E helicopters and those parts are 

not approved for installation on that 

helicopter model. During revisions to 

the Model A109E technical publications 

it was noted that the 90-degree tail rotor 

gearbox assembly, part number (P/N) 

109–0440–01–115, is included in the 

illustrated parts catalog (IPC) for 

helicopters with serial numbers (S/N) 

up to and including S/N 11160. The IPC 

incorrectly identifies this part number 

as a replacement part for P/N 109–0440– 

01–119 or P/N 109–0440–01–121. 

The FAA is proposing this AD to 

address installation of tail rotor gearbox 

assembly P/N 109–0440–01–115 that is 

not approved for installation on Model 

A109E helicopters. Because P/N 109– 

0440–01–115 is not part of the type 

design for Model A109E helicopters, 

there are no overhaul or life limits 

included in the applicable maintenance 

manuals. If a tail rotor gearbox is not 

properly maintained it could fail, 

resulting in reduced control of the 

helicopter. See EASA AD 2021–0031 for 

additional background information. 

Related Service Information Under 1 

CFR Part 51 

EASA AD 2021–0031 requires 

replacement of a tail rotor gearbox 

assembly P/N 109–0440–01–115 with a 

serviceable part. EASA AD 2021–0031 

also prohibits installation of tail rotor 

gearbox assembly P/N 109–0440–01– 

115 on any Leonardo S.p.A. Model 

A109E helicopter. 

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 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 2021–0031, 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 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 2021–0031 by 

reference in the FAA final rule. This 

proposed AD would, therefore, require 

compliance with EASA AD 2021–0031 

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 2021–0031 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 2021–0031. 

Service information required by EASA 

AD 2021–0031 for compliance will be 

available at https://www.regulations.gov 

by searching for and locating Docket No. 

FAA–2021–0695 after the FAA final 

rule is published. 

Costs of Compliance 

The FAA estimates that this AD, if 

adopted as proposed, would affect 70 

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 

Cost on U.S. 

operators 

Replacement ................................................... 12 work-hours × $85 per hour = $1,020 ........ $82,500 $83,520 $5,846,400 

The FAA has included all known 

costs in its cost estimate. According to 

the manufacturer, however, some of the 

costs of this proposed AD may be 

covered under warranty, thereby 

reducing the cost impact on affected 

operators. 

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.

Federal Register / Vol. 86, No. 162 / Wednesday, August 25, 2021 / Proposed Rules 47429 

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–2021– 

0695; Project Identifier MCAI–2021– 

00096–R. 

(a) Comments Due Date 

The FAA must receive comments on this 

airworthiness directive (AD) by October 12, 

2021. 

(b) Affected ADs 

None. 

(c) Applicability 

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

A109E helicopters, certificated in any 

category, with an affected part as identified 

in European Union Aviation Safety Agency 

(EASA) AD 2021–0031, dated January 22, 

2021 (EASA AD 2021–0031) installed. 

(d) Subject 

Joint Aircraft Service Component (JASC) 

Code: 6520, Tail Rotor Gearbox. 

(e) Unsafe Condition 

This AD was prompted by reports that 

certain tail rotor gearbox assemblies were 

installed on Model A109E helicopters and 

those parts are not approved for installation 

on that helicopter model. Because tail rotor 

gearbox assembly part number (P/N) 109– 

0440–01–115 is not part of the type design 

for Model A109E helicopters, there are no 

overhaul or life limits included in the 

applicable maintenance manuals. The FAA is 

issuing this AD to address installation of tail 

rotor gearbox assembly P/N 109–0440–01– 

115 on Model A109E helicopters that do not 

have overhaul or life limits for that part. If 

a tail rotor gearbox is not properly 

maintained it could fail, resulting in reduced 

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 

compliance times specified in, and in 

accordance with, EASA AD 2021–0031. 

(h) Exceptions to EASA AD 2021–0031 

(1) Where EASA AD 2021–0031 requires 

compliance in terms of flight hours, this AD 

requires using hours time-in-service. 

(2) Where EASA AD 2021–0031 requires 

compliance from its effective date, this AD 

requires using the effective date of this AD. 

(3) This AD does not require the 

‘‘Remarks’’ section of EASA AD 2021–0031. 

(i) No Reporting Requirement 

Although the service information 

referenced in EASA AD 2021–0031 specifies 

to submit certain information to the 

manufacturer, this AD does not include that 

requirement. 

(j) Alternative Methods of Compliance 

(AMOCs) 

(1) The Manager, International Validation 

Branch, FAA, has the authority to approve 

AMOCs for this AD, if requested using the 

procedures found in 14 CFR 39.19. In 

accordance with 14 CFR 39.19, send your 

request to your principal inspector or local 

Flight Standards District Office, as 

appropriate. If sending information directly 

to the manager of the International Validation 

Branch, send it to the attention of the person 

identified in paragraph (k)(2) of this AD. 

Information may be emailed to: 9-AVS-AIR730-AMOC@faa.gov. 

(2) Before using any approved AMOC, 

notify your appropriate principal inspector, 

or lacking a principal inspector, the manager 

of the local flight standards district office/ 

certificate holding district office.
