Federal Register / Vol. 86, No. 160 / Monday, August 23, 2021 / Proposed Rules 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 FAAs 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 Agencys 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.

The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

DIRECTIVES
1. The authority citation for part 39
continues to read as follows:
Authority: 49 U.S.C. 106g, 40113, 44701.
39.13

Leonardo S.p.a.: Docket No. FAA2021
0687; Project Identifier 2019SW029
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
20190039.
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 20190039.
h Exceptions to EASA AD 20190039
1 Where EASA AD 20190039 requires compliance in terms of flight hours, this AD
requires using hours time-in-service.
2 Where EASA AD 20190039 refers to its effective date, this AD requires using the effective date of this AD.
3 Where the service information required by EASA AD 20190039 specifies discarding parts, this AD requires removing those parts from service.
4 This AD does not require the Remarks section of EASA AD 20190039.

Sfmt 9990

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.
