Abstract
The FAA proposes to adopt a new airworthiness directive (AD) for certain Leonardo S.p.a. Model A109S and AW109SP helicopters. This proposed AD was prompted by a report of a protective sheath, installed around a fixed flight control rod, which should have been removed during assembly. This proposed AD would require borescope inspecting certain parts, and removing any foreign object if detected, 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.

Background
EASA, which is the Technical Agent for the Member States of the
European Union, has issued EASA AD 2021-0255, dated November 15, 2021,
and corrected November 24, 2021 (EASA AD 2021-0255), to correct an
unsafe condition for Leonardo S.p.A. Helicopters Model A109S
helicopters, serial number (S/N) 22735, 22736, and 22737, and equipped
with Trekker Kit; and Model AW109SP helicopters, S/N 22407, 22408,
22409, 22412, 22414 to 22427 inclusive, and 22429.
This proposed AD was prompted by a report of a protective sheath,
installed around a fixed flight control rod, which should have been
removed during assembly. The FAA is proposing this AD to detect any
foreign object contamination, which if not addressed, could affect the
free movement of the flight controls and result in subsequent reduced
control of the helicopter. See EASA AD 2021-0255 for additional
background information.
Related Service Information Under 1 CFR Part 51
EASA AD 2021-0255 specifies procedures for borescope inspecting
certain part-numbered parts installed on the control rods and levers of
the rotors flight controls, and removing any foreign object if
detected.
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.
Other Related Service Information
The FAA reviewed Leonardo Helicopters Alert Service Bulletin No.
109SP-148, dated October 26, 2021 (ASB 109SP-148). This service
information specifies instructions for borescope inspecting certain
part-numbered parts installed on the control rods and levers of the
rotors flight controls of the left-hand and right-hand forward struts
and removing foreign objects.
The FAA also reviewed Leonardo Helicopters Alert Service Bulletin
No.109S-104, dated October 26, 2021, which specifies the same
instructions as ASB 109SP-148 but only applies to Model A109S
helicopters with certain Trekker Kits installed.
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 these same type designs.
Proposed AD Requirements in This NPRM
This proposed AD would require accomplishing the actions specified
in EASA AD 2021-0255, 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 2021-0255 by reference in the FAA
final rule. This proposed AD would, therefore, require compliance with
EASA AD 2021-0255 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 2021-0255 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-
0255. Service information referenced in EASA
[[Page 16122]]
AD 2021-0255 for compliance will be available at <a href="https://www.regulations.gov">https://www.regulations.gov</a> by searching for and locating Docket No. FAA-2022-
0281 after the FAA final rule is published.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would
affect 1 helicopter 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 proposed AD.
Borescope inspecting the control rods and levers of the rotor
flight controls for any foreign object would take about 4 work-hours
for an estimated cost of $340 per inspection and $340 for the U.S.
fleet.
The FAA estimates the following costs to do any necessary on-
condition corrective actions that would be required based on the
results of the inspection:
If required, removing any foreign object would take a minimal
amount of time with a minimal parts cost.
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.
