Background

    The EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2020-0246, dated November 10, 2020 
(EASA AD 2020-0246), to correct an unsafe condition for certain Airbus 
Helicopters Deutschland GmbH, formerly Eurocopter Deutschland GmbH 
Model MBB-BK 117 D-2 helicopters.
    This proposed AD was prompted by a report of chafing marks on a 
wiring harness near the locking washer of the lateral control rod. The 
FAA is proposing this AD to address chafing marks on a wiring harness 
near the locking washer of the lateral control rod, which 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 2020-0246 for additional background information.

Related Service Information Under 1 CFR Part 51

    EASA AD 2020-0246 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.

FAA's Determination

    These helicopters have been approved by EASA and are approved for 
operation

[[Page 51043]]

in the United States. Pursuant to the FAA's bilateral agreement with 
the European Union, EASA has notified the FAA about the unsafe 
condition described in its AD. The FAA is proposing this AD after 
evaluating all known relevant information and determining that the 
unsafe condition described previously is likely to exist or develop on 
other helicopters of the same type design.

Proposed AD Requirements in This NPRM

    This proposed AD would require accomplishing the actions specified 
in EASA AD 2020-0246, 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 Proposed AD and the EASA AD.''

Explanation of Required Compliance Information

    In the FAA's ongoing efforts to improve the efficiency of the AD 
process, the FAA developed a process to use some civil aviation 
authority (CAA) ADs as the primary source of information for compliance 
with requirements for corresponding FAA ADs. The FAA has been 
coordinating this process with manufacturers and CAAs. As a result, the 
FAA proposes to incorporate EASA AD 2020-0246 by reference in the FAA 
final rule. This proposed AD would, therefore, require compliance with 
EASA AD 2020-0246 in its entirety through that incorporation, except 
for any differences identified as exceptions in the regulatory text of 
this proposed AD. Using common terms that are the same as the heading 
of a particular section in EASA AD 2020-0246 does not mean that 
operators need comply only with that section. For example, where the AD 
requirement refers to ``all required actions and compliance times,'' 
compliance with this AD requirement is not limited to the section 
titled ``Required Action(s) and Compliance Time(s)'' in EASA AD 2020-
0246. Service information required by EASA AD 2020-0246 for compliance 
will be available at https://www.regulations.gov by searching for and 
locating Docket No. FAA-2021-0779 after the FAA final rule is 
published.

Differences Between This Proposed AD and the EASA AD

    EASA AD 2020-0246 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, if adopted as proposed, would 
affect 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 proposed AD.

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                     Cost per      Cost on  U.S.
               Action                         Labor cost            Parts cost        product        operators
----------------------------------------------------------------------------------------------------------------
Inspection.........................  1 work-hour x $85 per hour               $0             $85          $2,635
                                      = $85.
----------------------------------------------------------------------------------------------------------------

    The FAA estimates the following costs to do any necessary repairs 
and re-routing that would be required based on the results of the 
proposed inspection. The agency has no way of determining the number of 
aircraft that might need these repairs:

                                               On-Condition Costs
----------------------------------------------------------------------------------------------------------------
                                                                                                     Cost per
                   Action                                 Labor cost                Parts cost        product
----------------------------------------------------------------------------------------------------------------
Repairs and re-routing.....................  Up to 1 work-hour x $85 per hour =             $0 *             $85
                                              $85.
----------------------------------------------------------------------------------------------------------------
* The FAA has received no definitive data on which to base the cost estimates for the on-condition repairs
  specified in this proposed AD.

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

    The FAA determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 this proposed 
regulation:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Would not affect intrastate aviation in Alaska, and
    (3) Would not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
