RIN 2120-AA64


Airworthiness Directives; Leonardo S.p.a. Helicopters

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for certain Leonardo S.p.a. Model AW169 helicopters. This proposed AD 
was prompted by a report of a broken adjustable device that is part of 
the pilot and co-pilot yaw pedal assemblies. This proposed AD would 
require modification of the pilot and co-pilot yaw pedal assemblies, 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.

Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public 
disclosure. If your comments responsive to this NPRM contain commercial 
or financial information that is customarily treated as private, that 
you actually treat as private, and that is relevant or responsive to 
this NPRM, it is important that you clearly designate the submitted 
comments as CBI. Please mark each page of your submission containing 
CBI as ``PROPIN.'' The FAA will treat such marked submissions as 
confidential under the FOIA, and they will not be placed in the public 
docket of this NPRM. Submissions containing CBI should be sent to Jacob 
Fitch, Aerospace Engineer, COS Program Management Section, Operational 
Safety Branch, Compliance & Airworthiness Division, FAA, 10101 Hillwood

specifically designated as CBI will be placed in the public docket for 
this rulemaking.

Background

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2019-0252, dated October 10, 2019 
(EASA AD 2019-0252), to correct an unsafe condition for Leonardo S.p.A. 
(formerly Finmeccanica S.p.A and AgustaWestland S.p.A) Model AW169 
helicopters, all serial numbers. Although EASA AD 2019-0252 applies to 
all Model AW169 helicopters, this proposed AD would apply to 
helicopters with an affected part installed instead.
    This proposed AD was prompted by a report of a broken adjustable 
device that is part of the pilot and co-pilot yaw pedal assemblies. The 
results of the investigations determined that a modification of the 
pilot and co-pilot yaw pedal assemblies is required to prevent this 
kind of failure. The modification includes installing additional end 
stroke stops on the yaw pedal assemblies by replacing the existing 
bolts with bolts having a longer grip to house a wider washer that acts 
as an additional stop in case of a yaw pedal adjuster failure. The FAA 
is proposing this AD to address failure of a yaw pedal adjuster, which 
could result in reduced yaw control of the helicopter. See EASA AD 
2019-0252 for additional background information.

Related Service Information Under 1 CFR Part 51

    EASA AD 2019-0252 requires modification (rework) of the affected 
pilot and co-pilot assemblies and re-identification of each affected 
part after it has been modified. EASA AD 2019-0252 also provides an 
option to replace an affected part with a non-affected part instead of 
doing the modification.
    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 and Requirements of This Proposed AD

    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 2019-0252, 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 certain 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, 
EASA AD 2019-0252 will be incorporated by reference in the FAA final 
rule. This proposed AD would, therefore, require compliance with EASA 
AD 2019-0252 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 2019-0252 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-
0252. Service information specified in EASA AD 2019-0252 that is 
required for compliance with it will be available at https://www.regulations.gov by searching for and locating Docket No. FAA-2021-
0570 after the FAA final rule is published.

Interim Action

    The FAA considers this proposed AD would be an interim action. If 
final action is later identified, the FAA might consider further 
rulemaking then.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 7 helicopters of U.S. Registry. The FAA estimates the following 
costs to comply with this proposed AD.

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                     Cost per      Cost on U.S.
                Action                         Labor cost           Parts cost        product        operators
----------------------------------------------------------------------------------------------------------------
Modify and re-identify affected parts.  2 work-hours x $85 per              $510            $680          $4,760
                                         hour = $170.
----------------------------------------------------------------------------------------------------------------

    The FAA has included all known costs in its cost estimate. 
According to the manufacturer, however, some 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.
