Airworthiness Directives; Airbus Helicopters Federal Aviation Administration FAA, DOT.
ACTION: Final rule.
AGENCY:

The FAA is superseding Airworthiness Directive AD 202024
03, which applied to certain Airbus Helicopters Model AS350B, AS350BA, AS350B1, AS350B2, AS350D, AS355E, AS355F, AS355F1, and AS355F2
helicopters. AD 20202403 required testing the UP/DOWN switches of a certain part-numbered DUNLOP cyclic stick grip, installing a placard, and revising the existing Rotorcraft Flight Manual RFM for your helicopter, or removing the DUNLOP cyclic stick grip.
This AD retains some requirements of AD 20202403 and also requires incorporating a new modification, and removing the placard and the RFM
amendment installed previously as required by AD 20202403. The additional actions are required as specified in a European Union Aviation Safety Agency EASA AD, which is incorporated by reference. This AD was prompted by the development of a modification MOD procedure by Airbus Helicopters for the electrical wiring of the hoist control of the DUNLOP cyclic stick. The FAA is issuing this AD to address the unsafe condition on these products.
DATES: This AD is effective November 4, 2021.
The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD
as of November 4, 2021.

SUPPLEMENTARY INFORMATION:
Background EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 20210023, dated January 19, 2021 EASA AD
20210023 to correct an unsafe condition for Airbus Helicopters Model AS 350 and AS 355 helicopters.
The FAA issued a notice of proposed rulemaking NPRM to amend 14 CFR
part 39 to supersede AD 20202403, Amendment 3921333 85 FR 76955, December 1, 2020 AD 20202403.
AD 20202403 applied to Airbus Helicopters Model AS350B, AS350BA, AS350B1, AS350B2, AS350D, AS355E, AS355F, AS355F1, and AS355F2
helicopters with DUNLOP cyclic stick grip manufacturer part number MP/N
AC66444 with UP/DOWN switches for rescue hoist control installed. The NPRM published in the Federal Register on July 12, 2021 86 FR 36516.
The NPRM was prompted by Airbus Helicopters developing MOD MC20096
and Airbus Helicopters issuing service information for performing this modification on the DUNLOP cyclic stick. The NPRM proposed to continue
PO 00000

Frm 00007

Fmt 4700

Sfmt 4700

54035

to require ground testing of the UP/
DOWN switches, installing a placard, and revising the existing RFM for your helicopter. The NPRM also proposed to require modifying the electrical wiring of the DUNLOP cyclic stick and removing both the placard and RFM
amendment previously installed as specified in EASA AD 20210023.
The FAA is issuing this AD to address inadvertent activation of the rescue hoist cable cutter function and consequent detachment of an external load or person from the helicopter hoist, possibly resulting in personal injury, or injury to persons on the ground, as specified in an EASA AD. See EASA AD
20210023 for additional background information.
Discussion of Final Airworthiness Directive Comments The FAA gave the public the opportunity to participate in developing this final rule. The FAA received no comments on the NPRM or on the determination of the cost to the public.
Conclusion The FAA reviewed the relevant data and determined that air safety and the public interest require adopting this final rule as proposed, except for minor editorial changes. As published in the NPRM, three instances of EASA AD
20200023 have been changed to EASA AD 20210023 in this Final rule. These minor changes correct a typographical error and the FAA has determined that they:
Are consistent with the intent that was proposed in the NPRM for addressing the unsafe condition; and Do not add any additional burden upon the public than was already proposed in the NPRM.
Related Service Information Under 1
CFR Part 51
EASA AD 20210023 specifies procedures for installing the placard and revising the Flight Manual to prohibit the use of the UP/DOWN
switches of the DUNLOP cyclic stick MP/N AC66444. EASA AD 20210023
also specifies procedures for modifying the electrical wiring of the DUNLOP
cyclic stick and removing both the placard and RFM amendment previously installed.
