Background 

The EASA, which is the Technical 

Agent for the Member States of the 

European Union, has issued EASA AD 

2019–0039, dated February 20, 2019 

(EASA AD 2019–0039), to correct an 

unsafe condition for certain Leonardo 

S.p.A. Model AW189 helicopters. 

This proposed AD was prompted by 

a report that a number of fairleads that 

support the engine combustion chamber 

D1 drain hose showed evidence of heat 

damage. The FAA is proposing this AD 

to address heat damage, which in a case 

where the right-hand engine is operated 

in the one engine inoperative (OEI) 

rating, the D1 drain pipe could transfer 

so much heat to the nearby fuel system 

vent pipe that its internal surface 

temperature could exceed the autoignition temperature for fuel. The unsafe 

condition, if not addressed, could result 

in undetected fire ignition in the fuel 

tank bay with consequent loss of the 

helicopter. See EASA AD 2019–0039 for 

additional background information. 

Related Service Information Under 1 

CFR Part 51 

EASA AD 2019–0039 requires 

modifying the helicopter by installing 

the engine combustion chamber D1 

drain assembly, part number 

8G7170P00111. 

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 

This helicopter has been approved by 

EASA and is 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 2019–0039, 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 2019–0039 by 

reference in the FAA final rule. This 

proposed AD would, therefore, require 

compliance with EASA AD 2019–0039 

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 

EASA AD 2019–0039 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 2019–0039. 

Service information required by EASA 

AD 2019–0039 for compliance will be 

available at https://www.regulations.gov 

by searching for and locating Docket No. 

FAA–2021–0687 after the FAA final 

rule is published. 

Costs of Compliance 

The FAA estimates that this AD, if 

adopted as proposed, would affect 4 

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 

Modification ..................................................... 4 work-hours × $85 per hour = $340 ............. $2,557 $2,897 $11,588 


jbell on DSKJLSW7X2PROD with PROPOSALS
Federal Register / Vol. 86, No. 160 / Monday, August 23, 2021 / Proposed Rules 47035 

The FAA has included all known 

costs in its cost estimate. According to 

the manufacturer, however, some or all 

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. 

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–2021– 

0687; Project Identifier 2019–SW–029– 

AD. 

(a) Comments Due Date 

The FAA must receive comments on this 

airworthiness directive (AD) by October 7, 

2021. 

(b) Affected ADs 

None. 

(c) Applicability 

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

AW189 helicopters, certificated in any 

category, as identified in European Union 

Aviation Safety Agency (EASA) AD 2019– 

0039, dated February 20, 2019 (EASA AD 

2019–0039). 

(d) Subject 

Joint Aircraft Service Component (JASC) 

Code: 7170, Engine Drains. 

(e) Unsafe Condition 

This AD was prompted by a report that a 

number of fairleads that support the engine 

combustion chamber D1 drain hose showed 

evidence of heat damage. The FAA is issuing 

this AD to address such heat damage, which 

in a case where the right-hand engine is 

operated in the one engine inoperative (OEI) 

rating, the D1 drain pipe could transfer so 

much heat to the nearby fuel system vent 

pipe that its internal surface temperature 

could exceed the auto-ignition temperature 

for fuel. The unsafe condition, if not 

addressed, could result in undetected fire 

ignition in the fuel tank bay with consequent 

loss 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 2019–0039. 

(h) Exceptions to EASA AD 2019–0039 

(1) Where EASA AD 2019–0039 requires 

compliance in terms of flight hours, this AD 

requires using hours time-in-service. 

(2) Where EASA AD 2019–0039 refers to its 

effective date, this AD requires using the 

effective date of this AD. 

(3) Where the service information required 

by EASA AD 2019–0039 specifies discarding 

parts, this AD requires removing those parts 

from service. 

(4) This AD does not require the 

‘‘Remarks’’ section of EASA AD 2019–0039. 

(i) No Reporting Requirement 

Although the service information 

referenced in EASA AD 2019–0039 specifies 

to submit certain information to the 

manufacturer, this AD does not include that 

requirement. 

(j) Special Flight Permit 

Special flight permits may be issued in 

accordance with 14 CFR 21.197 and 21.199 

to operate the airplane to a location where 

the airplane can be modified, provided the 

OEI rating is prohibited on the right-hand 

engine. 

(k) 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
