aircraft management computer (AMC). The FAA is issuing this AD to
address the unsafe condition on these products.

DATES: This AD is effective October 27, 2020.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of October 27,
2020.

SUPPLEMENTARY INFORMATION:

Discussion

The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 by adding an AD that would apply to all Airbus Helicopters
Deutschland GmbH Model MBB-BK 117 D-2 helicopters. The NPRM published
in the Federal Register on April 28, 2020 (85 FR 23489). The NPRM was
prompted by a report of an erroneous low rotor RPM indication after
establishing an OEI condition. The NPRM proposed to require a SW
modification for the AMC. The FAA is issuing this AD to address
erroneous low RPM indications, which could cause the pilot to make
inappropriate control inputs, resulting in damage to the helicopter or
injury to occupants.
The European Union Aviation Safety Agency (EASA), which is the
Technical Agent for the Member States of the European Union, has issued
EASA AD 2019-0208, dated August 22, 2019 (referred to after this as the
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to
correct an unsafe condition for all Airbus Helicopters Deutschland GmbH
Model MBB-BK 117 D-2 helicopters. You may examine the MCAI in the AD
docket on the internet at https://www.regulations.gov by searching for
and locating Docket No. FAA-2020-0342.

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. The FAA has determined that these
minor changes:
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

Airbus Helicopters has issued Alert Service Bulletin MBB-BK117 D-2-
42A-005, Revision 3, dated June 6, 2019. This service information
describes procedures for a SW modification for the AMC.
This service information 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 MCAI or Service Information


The MCAI provides a 60-day compliance time for accomplishing the SW
modification. This AD requires completion of the SW modification within
50 hours time-in-service.

Costs of Compliance

The FAA estimates that this AD affects 30 helicopters of U.S.
registry. The FAA estimates the following costs to comply with this AD:

Estimated Costs for Required Actions

Labor cost
Parts cost
Cost per product
Cost on U.S. operators
1 work-hour x $85 per hour = $85
$3,000
$3,085
$92,550

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.

List of Subjects in 14 CFR Part 39

reference, Safety.
