Costs of Compliance The FAA estimates that this AD
affects 24 helicopters of U.S. Registry.
Labor rates are estimated at $85 per work-hour. Based on these numbers, the FAA estimates that operators may incur the following costs in order to comply with this AD.
Modifying the electrical control circuit of the MGB EMLUB system takes about 22 work-hours and parts cost about $1,592 for an estimated cost of $3,462 per helicopter and $83,088 for the U.S. fleet.
Functional testing the EMLUB system takes about 12 work-hours for an estimated cost of $1,020 per helicopter and $24,480 for U.S. fleet, per testing cycle. If the electrical functional test results in a need to replace the lubrication printed circuit board, the replacement time takes about 2 workhours and parts cost about $5,150 for an estimated cost of $5,320 per helicopter.

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 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

List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.
The Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows:
PART 39AIRWORTHINESS
DIRECTIVES
1. The authority citation for part 39
continues to read as follows:

Authority: 49 U.S.C. 106g, 40113, 44701.
39.13

Amended
2. The FAA amends 39.13 by adding the following new airworthiness directive:

20211105 Airbus Helicopters:
Amendment 3921567; Docket No.
FAA20210016; Project Identifier 2019SW114AD.
a Effective Date This airworthiness directive AD is effective July 12, 2021.
b Affected Airworthiness Directives None.
c Applicability This AD applies to all Airbus Helicopters Model EC225LP helicopters, certificated in any category.
d Subject Joint Aircraft System Component JASC
Code 6397, Main Rotor Drive System Wiring.
e Reason This AD was prompted by reports of oil leaks during engine starting, originating from the main gearbox MGB. The FAA is issuing this AD to address the inadvertent opening of the P 2.4 valve of the MGB emergency lubrication EMLUB system, which results from MGB pressurization by compressed air produced by the engine during starting in response to a signal from the EMLUB
electronic control card. This condition could result in loss of the MGB lubrication system and a reduced ability of the crew to manage adverse operating conditions.
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 European Union Aviation
