20150017, dated February 4, 2015
EASA AD 20150017, to correct an unsafe condition for certain Airbus Helicopters Deutschland GmbH Model BO105 A, BO105 C, BO105 D, BO105 S, and BO105 LS A3 helicopters.
The FAA issued a notice of proposed rulemaking NPRM to amend 14 CFR
part 39 by adding an AD that would apply to certain Model BO105A, BO
105C, BO105S, and BO105LS A3
helicopters. The NPRM published in the Federal Register on April 19, 2021 86
FR 20341. The NPRM was prompted by an uncommanded activation of the hoist cable cutter function on an MBBBK117
C1 helicopter which prompted a design review of the BO105 hoist control grip with coiled cable. The NPRM proposed to require

accomplishing the actions specified in EASA AD 20150017, 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 AD and the EASA AD.
The FAA is issuing this AD to prevent uncommanded cutting of the hoist cable and subsequent injury to persons being lifted by the hoist and injury to persons on the ground. See the EASA AD 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 in the NPRM.
