Abstract
The FAA is adopting a new airworthiness directive (AD) for all H[eacute]licopt[egrave]res Guimbal (HG) Model Cabri G2 helicopters. The FAA previously sent this AD as an emergency AD to all known U.S. owners and operators of these helicopters. This AD was prompted by a report that was received of a crack on the main rotor (MR) mast after the crew reported an abnormal increase of vibration. This AD requires inspecting the MR mast for cracks and corrosion pitting, and depending on the results of the inspection, accomplishing corrective actions. This AD also requires modifying the MR mast, which includes applying corrosion protection to the MR mast, reporting the inspection results and prohibiting the installation of a certain main gear box (MGB), unless certain requirements are met. The FAA is issuing this AD to address the unsafe condition on these products.

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all
H[eacute]licopt[egrave]res Guimbal (HG) Model Cabri G2 helicopters. The
FAA previously sent this AD as an emergency AD to all known U.S. owners
and operators of these helicopters. This AD was prompted by a report
that was received of a crack on the main rotor (MR) mast after the crew
reported an abnormal increase of vibration. This AD requires inspecting
the MR mast for cracks and corrosion pitting, and depending on the
results of the inspection, accomplishing corrective actions. This AD
also requires modifying the MR mast, which includes applying corrosion
protection to the MR mast, reporting the inspection results and
prohibiting the installation of a certain main gear box (MGB), unless
certain requirements are met. The FAA is issuing this AD to address the
unsafe condition on these products.

Background
The FAA issued Emergency AD 2026-10-51, dated May 15, 2026 (also
referred to as the emergency AD), to address an unsafe condition on
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 inspecting the MR mast for
cracks and corrosion pitting, and depending on the results of the
inspection, the emergency AD requires accomplishing the corrective
actions. The emergency AD also requires modifying the MR mast, which
includes applying corrosion protection to the MR mast and reporting
inspection results within 14 days after accomplishment of the
inspection. The emergency AD prohibits installing an MGB having part
number (P/N) G21-10-000, P/N G21-10-001, P/N G21-10-002, or P/N G21-10-
003, unless certain requirements are met.
Emergency AD 2026-10-51 was prompted by European Union Aviation
Safety Agency (EASA) Emergency AD 2026-0095-E, dated May 12, 2026 (also
referred to as the MCAI), issued by EASA, which is the Technical Agent
for
[[Page 34741]]
the Member States of the European Union, to correct an unsafe condition
on H[eacute]licopt[egrave]res Guimbal Model Cabri G2 helicopters. The
MCAI states a report was received of a crack on the MR mast after the
crew reported an abnormal increase of vibration.
The FAA is issuing this AD to detect and correct any cracks or
corrosion on the MR mast. This condition, if not detected and
corrected, could lead to failure of the MR mast, possibly resulting in
loss of control of the helicopter.
You may examine the MCAI in the AD docket at <a href="http://regulations.gov">regulations.gov</a> under
Docket No. FAA-2026-4650.
Material Incorporated by Reference Under 1 CFR Part 51
The FAA reviewed Guimbal Service Bulletin SB 26-009 B, Revision B,
dated May 13, 2026. This material specifies procedures for disassembly
of the MR mast, inspection of the MR mast for a crack or corrosion
pitting, and corrective actions, which include removing affected parts
from service and contacting HG customer support for further
instructions.
The FAA also reviewed Guimbal Service Bulletin SB 18-023 E,
Revision E, dated May 13, 2026, which specifies procedures for
inspecting the MR mast for corrosion and applying protective coatings.
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 products have been approved by the civil aviation authority
of another country and are approved for operation in the United States.
Pursuant to the FAA's bilateral agreement with this State of Design
Authority, that authority has notified the FAA of the unsafe condition
described in the MCAI and material referenced above. The FAA is issuing
this AD after determining that the unsafe condition described
previously is likely to exist or develop on other products of the same
type design.
AD Requirements
This AD requires accomplishing the actions specified in the
material already described, except as discussed under ``Differences
Between this AD and the Referenced Material.''
Differences Between This AD and the Referenced Material
Where the referenced material specifies contacting HG for repair
instructions or corrective actions, this AD requires using a method
approved by the FAA, EASA, or H[eacute]licopt[egrave]res Guimbal's EASA
Design Organization Approval (DOA).
Interim Action
The FAA considers that this AD is an interim action. If final
action is later identified, the FAA might consider additional
rulemaking.
Justification for Immediate Adoption and Determination of the Effective
Date
Section 553(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 2026-10-51, issued on May 15, 2026, to all known U.S.
owners and operators of these helicopters. The FAA found that the risk
to the flying public justified forgoing notice and comment prior to
adoption of this rule because the MR mast is critical to flight of a
helicopter. Cracking of the MR mast may lead to destruction of the MR
mast, departure of the main rotor head, and loss of control of the
helicopter. Since the FAA has no information pertaining to the extent
of cracking of the MR mast that may currently exist in helicopters, the
initial actions required by this AD must be accomplished before further
flight for certain helicopters. This compliance time is shorter than
the time necessary for the public to comment and for the publication of
the final rule. 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).
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 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 67 helicopters of U.S.
registry.
The FAA estimates the following costs to comply with this AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
Inspect MR mast..................... 8 work-hours x $85 per $117................... $797 $53,399
hour = $680.
Modify MR mast...................... 2 work-hours x $85 per $0 (nominal amount for 170 11,390
hour = $170. modification).
----------------------------------------------------------------------------------------------------------------
The FAA estimates the following costs to do any necessary repairs
that would be required based on the results of the inspection. The
agency has no way of determining the number of helicopters that might
need this repair:
On-Condition Costs
----------------------------------------------------------------------------------------------------------------
Action Labor cost Parts cost Cost per product
----------------------------------------------------------------------------------------------------------------
Apply corrosion protection.................... 2 work-hours x $85 per hour = $0 $170
$170.
Report inspection results..................... 1 work-hour x $85 per hour = $85. $0 $85
----------------------------------------------------------------------------------------------------------------
[[Page 34742]]
The extent of the MR mast repairs that may be needed could vary
significantly from helicopter to helicopter. The FAA has no way of
determining the work-hours it may take to perform these repairs or the
number of helicopters that may require repair. However, according to
the manufacturer, the cost of an MR mast repair (overhaul) may cost up
to $19,950 per repair.
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 currently 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 be
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
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 above, 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.
