Federal Register / Vol. 86, No. 119 / Thursday, June 24, 2021 / Rules and Regulations
the FAA AD. Per 14 CFR 21.5, an approved RFM must be presented to the owner upon delivery of the rotorcraft.
Unless required through an operational certificate or operational specification, the rotorcraft owner is not required by regulation to adopt flight manual revisions made after delivery of the rotorcraft. To mandate a change to the RFM to address the unsafe condition, the FAA must issue an AD.
Conclusion These helicopters have been approved by EASA and are approved for operation in the United States. Pursuant to the FAAs bilateral agreement with the European Union, EASA has notified the FAA about the unsafe condition described in its AD. The FAA reviewed the relevant data, considered the comments received, and determined that air safety requires adopting this AD
as proposed. Accordingly, the FAA is issuing this AD to address the unsafe condition on these helicopters.

Other Related Service Information The FAA also reviewed Safran Turbomeca Mandatory Service Bulletin No. 292 73 2852, Revision B, dated February 12, 2014. This service information specifies replacing certain FADEC D EECUs with certain amended FADEC D EECUs.
Differences Between This AD and the EASA AD
The EASA AD applies to Model AS350B3 and EC130T2 helicopters, with an ARRIEL 2D engine and THALES
FADEC P/N C13165DA00 or P/N
C13165FA00 installed, whereas this AD
applies to those helicopters except not those with THALES FADEC P/N
C13165DA00 with amendment A or P/
N C13165FA00 with amendment B
installed. This AD also allows installing those amendments on the FADEC as an optional terminating action, whereas the EASA AD does not.

Costs of Compliance The FAA estimates that this AD
affects up to 628 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 this AD.
Revising the existing RFM for your helicopter takes about 0.25 work-hour for an estimated cost of $21 per helicopter and up to $13,188 for the U.S. fleet.
Authority for This Rulemaking
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:

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 helicopters identified in this rulemaking action.
