Abstract
The FAA is adopting a new airworthiness directive (AD) for all H[eacute]licopt[egrave]res Guimbal Model Cabri G2 helicopters. This AD was prompted by reports of a crack in the pilot cyclic stick base. This AD requires repetitively inspecting certain part-numbered pilot and co- pilot cyclic stick bases and, depending on the results, corrective action. This AD also prohibits installing those pilot and co-pilot cyclic stick bases unless certain requirements are met. These actions are specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA previously sent this AD as an emergency AD to all known U.S. owners and operators of these helicopters. The FAA is issuing this AD to address the unsafe condition on these products.

Background
The FAA issued Emergency AD 2023-24-51, dated November 21, 2023
(the emergency AD), to address an unsafe condition on all
H[eacute]licopt[egrave]res Guimbal Model Cabri G2 helicopters. The FAA
sent the emergency AD to all known U.S. owners and operators of these
helicopters. The emergency AD requires repetitively inspecting certain
part-numbered pilot and co-pilot cyclic stick bases for a crack and,
depending on the results, removing the cracked cyclic stick base from
service and replacing it with a serviceable cyclic stick base in
accordance with a method approved by the FAA, EASA, or
H[eacute]licopt[egrave]res Guimbal EASA Design Organization Approval
(DOA). The emergency AD also prohibits installing an affected pilot or
co-pilot cyclic stick base unless it is new (zero total hours time-in-
service) or it has passed its required inspection.
The emergency AD was prompted by EASA Emergency AD 2023-0204-E,
dated November 20, 2023 (EASA AD 2023-0204-E), issued by EASA, which is
the Technical Agent for the Member States of the European Union, to
correct an unsafe condition on H[eacute]licopt[egrave]res Guimbal Model
Cabri G2 helicopters. EASA AD 2023-0204-E states that further
investigation determined that the root cause of the cracks is fatigue,
primarily related to induced loads on the cyclic stick during pre-
flight (free play) checks. Accordingly, EASA AD 2023-0204-E requires
repetitively inspecting certain part-numbered pilot and co-pilot cyclic
stick bases and, depending on the results, corrective action. EASA AD
2023-0204-E also prohibits installing those pilot and co-pilot cyclic
stick bases unless its requirements are met.
You may examine EASA AD 2023-0204-E in the AD docket at
<a href="http://regulations.gov">regulations.gov</a> under Docket No. FAA-2023-2239.
The FAA is issuing this AD to detect a cracked pilot or co-pilot
cyclic stick base. This condition, if not addressed, could result in
failure of the pilot or co-pilot cyclic stick base and subsequent loss
of control of the helicopter.
Related Service Information Under 1 CFR Part 51
The FAA reviewed EASA AD 2023-0204-E, which requires repetitively
inspecting pilot cyclic stick base part number (P/N) G41-42-801 and co-
pilot cyclic stick base P/Ns G41-43-801 and G41-43-802 for a crack.
Depending on the results, EASA AD 2023-0204-E requires contacting HG
[H[eacute]licopt[egrave]res Guimbal] for approved instructions to
replace a cracked cyclic stick base and accomplishing those
instructions accordingly. EASA AD 2023-0204-E also allows removing the
dual control (co-pilot cyclic stick) instead of replacing a cracked co-
pilot cyclic stick base. Lastly, EASA AD 2023-0204-E prohibits
installing a specified pilot or co-pilot cyclic stick base unless it is
a new (never installed before) part or, before installation, has passed
its required inspection.
The FAA also reviewed Guimbal Mandatory Service Bulletin SB 23-006,
Revision B, dated November 14, 2023 (SB 23-006B), which specifies
procedures for an initial and repetitive inspections of both the pilot
and copilot cyclic bases for cracks. SB 23-006B specifies doing the
inspection using a flashlight and in case of doubt, performing a dye-
penetrant inspection. If there is a crack on the pilot's side, SB 23-
006B specifies grounding the helicopter and contacting HG
[H[eacute]licopt[egrave]res Guimbal]; if there is a crack on the
copilot's side, SB 23-006B specifies removing the dual controls and
contacting HG.
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
These helicopters have been approved by the aviation authority of
the European Union and are approved for operation in the United States.
Pursuant to the FAA's bilateral agreement with the European Union,
EASA, its technical representative, has notified the FAA of the unsafe
condition described in its emergency AD. The FAA is issuing this AD
after evaluating all pertinent information and determining that the
unsafe condition exists and is likely to exist or develop on other
helicopters of the same type design.
Requirements of This AD
This AD requires accomplishing the actions specified in EASA AD
2023-0204-E, described previously, as incorporated by reference, except
for any differences identified as exceptions in the regulatory text of
this AD and except as discussed under ``Differences Between this AD and
the EASA Emergency 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,
EASA AD 2023-0204-E is incorporated by reference in this FAA final
rule. This AD, therefore, requires compliance with EASA AD 2023-0204-E
in its entirety through that incorporation, except for any differences
identified as exceptions in the regulatory text of this AD. Using
common terms that are the same as the heading of a particular section
in EASA AD 2023-0204-E 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 2023-0204-E. Service information
referenced in EASA AD 2023-0204-E for compliance will be available at
<a href="http://regulations.gov">regulations.gov</a> under Docket No. FAA-2023-2239 after this final rule is
published.
Differences Between This AD and the EASA Emergency AD
The service information referenced in EASA AD 2023-0204-E specifies
performing a dye-penetrant inspection in case of a doubt regarding if
there is a crack, whereas this AD does not require that action. If
there is cracked
[[Page 86262]]
pilot or co-pilot cyclic stick base, EASA AD 2023-0204-E requires
contacting HG [H[eacute]licopt[egrave]res Guimbal] for approved
instructions to replace it with a serviceable part and accomplishing
those instructions accordingly and the service information referenced
in EASA AD 2023-0204-E specifies contacting HG
[H[eacute]licopt[egrave]res Guimbal] or removing the dual controls and
contacting HG [H[eacute]licopt[egrave]res Guimbal], whereas this AD
requires removing the cracked cyclic stick base from service and
replacing it with a serviceable cyclic stick base in accordance with a
method approved by the FAA, EASA, or H[eacute]licopt[egrave]res Guimbal
EASA DOA.
Justification for Immediate Adoption and Determination of the Effective
Date
Section 553(b)(3)(B) of the Administrative Procedure Act (APA) (5
U.S.C. 551 et seq.) authorizes agencies to dispense with notice and
comment procedures for rules when the agency, for ``good cause,'' finds
that those procedures are ``impracticable, unnecessary, or contrary to
the public interest.'' Under this section, an agency, upon finding good
cause, may issue a final rule without providing notice and seeking
comment prior to issuance. Further, section 553(d) of the APA
authorizes agencies to make rules effective in less than thirty days,
upon a finding of good cause.
An unsafe condition exists that required the immediate adoption of
Emergency AD 2023-24-51, issued on November 21, 2023, to all known U.S.
owners and operators of these helicopters. The FAA found that the risk
to the flying public justified waiving notice and comment prior to
adoption of this rule because the affected component is part of an
assembly that is critical to the control of a helicopter. As the FAA
also has no information pertaining to the quantity of cracked
components that may currently exist in the U.S. fleet or how quickly
the condition may propagate to failure, the actions required by this AD
must be accomplished before further flight for certain helicopters.
These conditions still exist, therefore, notice and opportunity for
prior public comment are impracticable and contrary to the public
interest pursuant to 5 U.S.C. 553(b)(3)(B).
In addition, the FAA finds that good cause exists pursuant to 5
U.S.C. 553(d) for making this amendment effective in less than 30 days,
for the same reasons the FAA found good cause to forego notice and
comment.
Regulatory Flexibility Act
The requirements of the Regulatory Flexibility Act (RFA) do not
apply when an agency finds good cause pursuant to 5 U.S.C. 553 to adopt
a rule without prior notice and comment. Because the FAA has determined
that it has good cause to adopt this rule without prior notice and
comment, RFA analysis is not required.
Costs of Compliance
The FAA estimates that this AD affects 49 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.
Inspecting a pilot or co-pilot cyclic stick base takes a minimal
amount of time for a nominal cost. If required, replacing a pilot
cyclic stick base takes about 3 work-hours and parts cost about $1,585
for an estimated cost of $1,840 per helicopter; and replacing a co-
pilot cyclic stick base takes about 1 work-hour and parts cost about
$711 for an estimated cost of $796 per helicopter.
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
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, I certify that this AD:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866, and
(2) Will not affect intrastate aviation in Alaska.
