Airworthiness Directives; Airbus Helicopters Deutschland GmbH

AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD)
for
certain Airbus Helicopters Deutschland GmbH Model MBB-BK 117 D-2
helicopters. This AD was prompted by a report of chafing marks on a
wiring harness near the locking washer of the lateral control rod. This
AD requires an inspection of the wiring harness and the routing of the
wiring harness and corrective actions if necessary, as specified in a
European Union Aviation Safety Agency (EASA) AD, which is incorporated
by reference. The FAA is issuing this AD to address the unsafe
condition on these products.
DATES: This AD is effective January 11, 2022.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of January 11,
2022.

SUPPLEMENTARY INFORMATION:
Background
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.
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 MBB-BK 117 D-2 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 2020-0246.
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 2020-0246 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 FAA's 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 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.
Differences Between This 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 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.
Estimated Costs

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

* The FAA has received no definitive
data on which to base the cost estimates
for the on-condition repairs specified in this 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
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.
