Abstract
The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Model EC120B helicopters. This AD was prompted by a report of cyclic flight control restrictions due to the incorrect positioning of the bonding braid on the socket of the pilot cyclic stick, which limited full movement of the pilot cyclic stick during flight. This AD requires a one-time inspection of the position of the bonding braid on the socket of the pilot cyclic stick and, depending on the results, correcting the positioning of the bonding braid and installing a binding clamp. The FAA is issuing this AD to address the unsafe condition on these products.

Airworthiness Directives; Airbus Helicopters
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all
Airbus Helicopters Model EC120B helicopters. This AD was prompted by a
report of cyclic flight control restrictions due to the incorrect
positioning of the bonding braid on the socket of the pilot cyclic
stick, which limited full movement of the pilot cyclic stick during
flight. This AD requires a one-time inspection of the position of the
bonding braid on the socket of the pilot cyclic stick and, depending on
the results, correcting the positioning of the bonding braid and
installing a binding clamp. The FAA is issuing this AD to address the
unsafe condition on these products.
DATES: This AD is effective April 7, 2026.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of April 7,
2026.

SUPPLEMENTARY INFORMATION:
Background
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 by adding an AD that would apply to all Airbus Helicopters
Model EC120B helicopters. The NPRM was published in the Federal
Register on November 28, 2025 (90 FR 54601). The NPRM was prompted by
EASA AD 2024-0243, dated December 13, 2024 (EASA AD 2024-0243) (also
referred to as the MCAI), issued by EASA, which is the Technical Agent
for the Member States of the European Union. The MCAI advises of a
report that a pilot experienced several occurrences of a cyclic flight
control restriction when turning right during an instruction flight.
Subsequent investigation determined that the bonding braid on the
socket of the pilot cyclic stick had moved to an incorrect position,
which limited full movement of the pilot cyclic stick. This condition,
if not addressed, could result in a cyclic flight control restriction
during flight and consequent loss of control of the helicopter.
In the NPRM, the FAA proposed to require a one-time inspection of
the position of the bonding braid on the socket of the pilot cyclic
stick and, depending on the results, correcting the positioning of the
bonding braid and installing a binding clamp.
The FAA is issuing this AD to detect and correct the incorrect
positioning of the bonding braid on the socket of the pilot cyclic
stick. The unsafe condition, if not addressed, could result in a cyclic
flight control restriction during flight and consequent 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-2025-5036.
Discussion of Final Airworthiness Directive
Comments
The FAA received comments from one commenter. The commenter
supported the NPRM without change.
[[Page 10310]]
Conclusion
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 referenced above. The FAA reviewed the relevant
data, considered any comments received, and determined that air safety
requires adopting this AD as proposed. Accordingly, the FAA is issuing
this AD to address the unsafe condition on these products. Except for
minor editorial changes, this AD is adopted as proposed in the NPRM.
None of the changes will increase the economic burden on any operator.
Material Incorporated by Reference Under 1 CFR Part 51
The FAA reviewed EASA AD 2024-0243, which specifies a one-time
inspection of the position of the bonding braid on the socket of the
pilot cyclic stick and, depending on the results, correcting the
positioning of the bonding braid and installing a binding clamp. 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.
Costs of Compliance
The FAA estimates that this AD affects 72 helicopters of the 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 position of bonding braid and 1 work-hour x $85 per hour $0 $85 $6,120
install binding clamp. = $85.
----------------------------------------------------------------------------------------------------------------
The FAA estimates the following costs to do any 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
----------------------------------------------------------------------------------------------------------------
Correct position of bonding braid............. 1 work-hour x $85 per hour = $85 $0 $85
----------------------------------------------------------------------------------------------------------------
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,
(2) Will not affect intrastate aviation in Alaska, and
(3) Will not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.
