Federal Register / Vol. 86, No. 232 / Tuesday, December 7, 2021 / Rules and Regulations
SUPPLEMENTARY INFORMATION:

Background EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 20200246, dated November 10, 2020 EASA AD
20200246, to correct an unsafe condition for certain Airbus Helicopters Deutschland GmbH, formerly Eurocopter Deutschland GmbH Model MBBBK 117 D2 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 Airbus Helicopters Deutschland GmbH Model MBBBK 117
D2 helicopters. The NPRM published in the Federal Register on September 14, 2021 86 FR 51042. The NPRM was prompted by a report of chafing marks on a wiring harness near the locking washer of the lateral control rod. The NPRM proposed to require an inspection of the wiring harness and the routing of the wiring harness and corrective actions if necessary, as specified in EASA AD 20200246.
The FAA is issuing this AD to address chafing marks on a wiring harness near the locking washer of the lateral control rod. The unsafe condition, if not addressed, could result in in-flight loss of the hoist load and possible personal
injury, or could generate a burning smell and possible need for the flight crew to implement the applicable emergency procedure. See EASA AD
20200246 for additional background information.
Discussion of Final Airworthiness Directive Comments The FAA received no comments on the NPRM or on the determination of the costs.
Conclusion These helicopters have been approved by EASA and are approved for operation in the United States. Pursuant to the FAAs bilateral agreement with the European Union, EASA has notified the FAA about the unsafe condition described in its AD. The FAA reviewed the relevant data 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 helicopters. Except for minor editorial changes, this AD is adopted as proposed in the NPRM.
Related Service Information Under 1
CFR Part 51
EASA AD 20200246 requires an inspection of the wiring harness and the
routing of the wiring harness for discrepancies includes damaged wire harnesses and insufficient clearances and corrective actions includes repair of wire harnesses and re-routing the wire harness if necessary, and an update of the Aircraft Maintenance Programme AMP to incorporate certain tasks. 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.
Differences Between This AD and the EASA AD
EASA AD 20200246 requires revising the Aircraft Maintenance Programme AMP, whereas this proposed AD would not because not all U.S. operators are required to have a maintenance program.
Costs of Compliance The FAA estimates that this AD
affects 31 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.
