Abstract
The FAA proposes to adopt a new airworthiness directive (AD) for all Leonardo S.p.a. Model A109E, A109S, AW109SP, A119, and AW119 MKII helicopters. This proposed AD was prompted by multiple reports of excessive axial play on the ball bearing of the lower half of the main rotor (MR) rotating scissor assembly. This proposed AD would require one-time scissor coupling and axial play inspections and repetitive quantitative axial play inspections and, depending on the results, additional inspections and replacing certain parts. This proposed AD would also require reporting information and prohibit installing certain parts unless certain inspections have been accomplished as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products.

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 all Leonardo S.p.a. Model A109E, A109S, AW109SP, A119, and AW119
MKII helicopters. This proposed AD was prompted by multiple reports of
excessive axial play on the ball bearing of the lower half of the main
rotor (MR) rotating scissor assembly. This proposed AD would require
one-time scissor coupling and axial play inspections and repetitive
quantitative axial play inspections and, depending on the results,
additional inspections and replacing certain parts. This proposed AD
would also require reporting information and prohibit installing
certain parts unless certain inspections have been accomplished as
specified in a European Union Aviation Safety Agency (EASA) AD, which
is proposed for incorporation by reference. 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 2022-0037, dated March 7, 2022, and
corrected March 15, 2022 (EASA AD 2022-0037), to correct an unsafe
condition for all Leonardo S.p.A Model A109E, A109LUH, A109S, AW109SP,
A119, and AW119 MKII helicopters.
This proposed AD was prompted by multiple reports of excessive
axial play on the ball bearing of the lower half of the MR rotating
scissor assembly. In some cases, this resulted in dislodgement of the
ball bearing from its seat. The FAA is proposing this AD to detect and
address any excessive axial play of the MR rotating scissor assembly.
See EASA AD 2022-0037 for additional background information.
Related Service Information Under 1 CFR Part 51
For certain applicable model helicopters, EASA AD 2022-0037
requires accomplishing one-time MR rotating scissor coupling and axial
play checks. Depending on the results, EASA AD 2022-0037 requires
repetitively measuring the axial play or replacing certain parts. For
all applicable model helicopters, EASA AD 2022-0037 requires
accomplishing repetitive qualitative and quantitative axial play
[[Page 68000]]
checks and, depending on the results, repetitively measuring the axial
play or replacing certain parts. Furthermore, EASA AD 2022-0037
requires reporting certain information to the manufacturer and
prohibits installing certain parts on any helicopter unless the part
has passed required inspections.
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 also reviewed Leonardo Helicopters Alert Service Bulletin
(ASB) No. 109EP-177, Leonardo Helicopters ASB No. 109S-105, Leonardo
Helicopters ASB No. 109SP-149, and Leonardo Helicopters ASB No. 119-
111, each Revision A and dated March 3, 2022. This service information
specifies procedures for inspecting the MR rotating scissor coupling
and axial play, measuring the axial play, inspecting the qualitative
axial play, inspecting the quantitative axial play, and replacing
components of the MR rotating scissor assembly (scissor bracket flange
assembly, rotary scissor sleeve, lower scissor lever assembly, and
upper scissor lever assembly) and bushings.
FAA's Determination
These products have been approved by the aviation authority of
another country, and are approved for operation in the United States.
Pursuant to the FAA's bilateral agreement with the State of Design
Authority, it has notified the FAA of the unsafe condition described in
its AD described above. The FAA is issuing this NPRM after determining
that the unsafe condition described previously is likely to exist or
develop in other products of the same type designs.
Proposed AD Requirements in This NPRM
This proposed AD would require accomplishing the actions specified
in EASA AD 2022-0037, described previously, as incorporated by
reference, except for any differences identified as exceptions in the
regulatory text of this proposed AD and except as discussed under
``Differences Between this Proposed AD and the EASA 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 2022-0037 by reference in the FAA
final rule. This proposed AD would, therefore, require compliance with
EASA AD 2022-0037 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 2022-0037 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 2022-
0037. Service information referenced in EASA AD 2022-0037 for
compliance will be available at <a href="http://regulations.gov">regulations.gov</a> under Docket No. FAA-
2023-1894 after the FAA final rule is published.
Differences Between This Proposed AD and the EASA AD
EASA AD 2022-0037 applies to Model A109LUH helicopters, whereas
this proposed AD would not because that model is not FAA-type
certificated. EASA AD 2022-0037 refers to several actions as a
``check,'' whereas this proposed AD would refer to those actions as an
``inspection'' instead because those actions must be accomplished by
persons authorized under 14 CFR 43.3. EASA AD 2022-0037 requires
discarding certain parts, whereas this proposed AD would require
removing those parts from service instead.
Service information referenced in EASA AD 2022-0037 specifies to
contact Leonardo Helicopters for instructions as a result of certain M/
R rotating scissor maximum torque force check (inspection) results,
whereas this proposed AD would require accomplishing corrective action
in accordance with a method approved by the FAA, EASA, or Leonardo
S.p.a. Helicopters' EASA Design Organization Approval. EASA AD 2022-
0037 requires interpreting the MR rotating scissor coupling and axial
play inspection results (PASSED or FAILED) by using its required
service information, whereas this proposed AD would require
interpreting those results by using tables in the body of this proposed
AD and recorded results of certain inspections. Furthermore, if the
scissor coupling inspection result is an ``UNCERTAIN RESULT,'' the
service information referenced in EASA AD 2022-0037 specifies
contacting Leonardo Helicopters, whereas this proposed AD would
consider an ``UNCERTAIN RESULT'' as ``FAILED.''
EASA AD 2022-0037 requires accomplishing repetitive qualitative
axial play checks, whereas this proposed AD would not. EASA AD 2022-
0037 requires quantitative axial play checks within intervals not to
exceed 200 flight hours, whereas this proposed AD would require
quantitative axial play inspections within intervals not to exceed 55
hours time-in-service. The service information referenced in EASA AD
2022-0037 cautions that only approved personnel are permitted to
perform the bushing replacement, whereas this proposed AD would not
include that caution.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would
affect 204 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 proposed AD.
The one-time MR rotating scissor coupling and axial play
inspections would take about 2 work-hours for an estimated cost of $170
per helicopter and up to $34,680 for the U.S. fleet.
A quantitative axial play inspection would take about 1 work-hour
for an estimated cost of $85 per helicopter and $17,340 for the U.S.
fleet per inspection cycle.
Measuring the axial play would take about 1 work-hour for an
estimated cost of $85 per helicopter and $17,340 for the U.S. fleet per
inspection cycle.
Certain corrective action that may be needed as a result of an
inspection could vary significantly from helicopter to helicopter. The
FAA has no data to determine the costs to accomplish the corrective
action or the number of helicopters that may require corrective action.
Replacing the scissor bracket flange assembly would take about 4
work-hours and parts would cost about $8,099-11,574 (depending on part
number) for an estimated cost of $8,439-11,914 per replacement.
Alternatively, replacing its bushings would take about 2 work-hours and
parts would cost about $225 for an estimated cost of $395 per
replacement.
Replacing each rotary scissor sleeve would take about 2 work-hours
and parts would cost about $565 for an estimated cost of $735 per
replacement.
Replacing the lower scissor lever assembly (including the washer
and
[[Page 68001]]
retaining bolt) would take about 2 work-hours and parts would cost
about $3,308-3,385 (depending on part number) for an estimated cost of
$3,478-3,555 per replacement. Alternatively, replacing its bushings
would take about 2 work-hours and parts would cost about $225 for an
estimated cost of $395 per replacement.
Replacing the upper scissor lever assembly would take about 2 work-
hours and parts would cost about $2,219-3,015 (depending on part
number) for an estimated cost of $2,389-3,185 per replacement.
Alternatively, replacing its bushings would take about 2 work-hours and
parts would cost about $225 for an estimated cost of $395 per
replacement.
Reporting the inspection results to the manufacturer would take
about 1 work-hour for an estimated cost of $85 per report.
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.
Paperwork Reduction Act
A federal agency may not conduct or sponsor, and a person is not
required to respond to, nor shall a person be subject to a penalty for
failure to comply with a collection of information subject to the
requirements of the Paperwork Reduction Act unless that collection of
information displays a current valid OMB Control Number. The OMB
Control Number for this information collection is 2120-0056. Public
reporting for this collection of information is estimated to take
approximately 1 hour per response, including the time for reviewing
instructions, searching existing data sources, gathering and
maintaining the data needed, and completing and reviewing the
collection of information. All responses to this collection of
information are mandatory. Send comments regarding this burden estimate
or any other aspect of this collection of information, including
suggestions for reducing this burden, to: Information Collection
Clearance Officer, Federal Aviation Administration, 10101 Hillwood
Parkway, Fort Worth, TX 76177-1524.
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.
