Federal Aviation
Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking
(NPRM).
AGENCY:
The FAA proposes to adopt a
new airworthiness directive (AD) for
certain Pilatus Aircraft Ltd. (Pilatus)
Model PC–24 airplanes. This proposed
AD results from mandatory continuing
airworthiness information (MCAI)
originated by an aviation authority of
another country to identify and correct
an unsafe condition on an aviation
product. The MCAI identifies the unsafe
condition as electrical harness
installations on PC–24 airplanes that are
not in compliance with the approved
design. This unsafe condition could
lead to wire chafing and potential arcing
or failure of wires having the incorrect

Discussion
The European Union Aviation Safety
Agency (EASA), which is the Technical
Agent for the Member States of the
European Union Community, has issued
EASA AD No. 2020–0158, dated July 16,
2020 (referred to after this as ‘‘the
VerDate Sep<11>2014
16:42 Sep 16, 2020
Jkt 250001
MCAI’’), to address an unsafe condition
on certain Pilatus Aircraft Ltd. (Pilatus)
Model PC–24 airplanes. The MCAI
states:
During production, electrical harness
installations on some PC–24 aeroplanes were
found not to comply with the approved
design.
This condition, if not corrected, could lead
to wire chafing and potential arcing, or to
failure of wires having the incorrect length,
possibly resulting in loss of system
redundancy, or generation of smoke and
smell, or loss of power plant fire protection
function.
To address this potential unsafe condition,
Pilatus issued the [service bulletin] SB,
providing instructions to improve the
electrical harness installations in the nose
bay, cockpit, fuselage, wing fairing and rear
fuselage areas.
For the reason described above, this
[EASA] AD requires modification of the
electrical harness installations.
The incorrect length wires are too
short in length and do not have
appropriate slack, which could lead to
wires being pulled loose from the
terminals during flight or ground
operation. Generation of smell refers to
the smell from electrical arcing.
You may obtain further information
by examining the MCAI in the AD
docket on the internet at https://
www.regulations.gov by searching for
and locating Docket No. FAA–2020–
0818.
Related Service Information Under 1
CFR Part 51
The FAA reviewed Pilatus PC–24
Service Bulletin No. 91–001, dated
April 7, 2020. The service information
specifies procedures necessary to
improve the electrical harness
installation in the nose bay, cockpit,
avionics rack, fuselage, wing fairing,
and rear fuselage. 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.
FAA’s Determination and Requirements
of the Proposed AD
This product has been approved by
the aviation authority of another
country and is approved for operation in
the United States. Pursuant to our
bilateral agreement with this State of
Design Authority, it has notified the
FAA of the unsafe condition described
in the MCAI and service information
referenced above. The FAA is proposing
this AD because the FAA evaluated all
information and determined the unsafe
condition exists and is likely to exist or
develop on other products of the same
type design.

Costs of Compliance
The FAA estimates that this proposed
AD would affect ßNumber_of_Aircraft®
products of U.S. registry. The FAA also
estimates that it would take 20 workhours per product to comply with the
requirements of this proposed AD. The
average labor rate is $85 per work-hour.
Required parts would cost about
ßInspect_Parts® per product.
Based on these figures, the FAA
estimates the cost of the proposed AD
on U.S. operators would be ßFleet_
Cost®, or $1,775 per product.
According to the manufacturer, some
of the costs of this AD may be covered
under warranty, thereby reducing the
cost impact on affected individuals. The
FAA does not control warranty coverage
for affected individuals. As a result, the
FAA has included all costs in this cost
estimate.
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) 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

Discussion
The European Union Aviation Safety Agency (EASA), which is the
Technical Agent for the Member States of the European Union Community,
has issued EASA AD No. 2020-0158, dated July 16, 2020 (referred to
after this as ``the MCAI''), to address an unsafe condition on certain
Pilatus Aircraft Ltd. (Pilatus) Model PC-24 airplanes. The MCAI states:
During production, electrical harness installations on some PC-
24 aeroplanes were found not to comply with the approved design.
This condition, if not corrected, could lead to wire chafing and
potential arcing, or to failure of wires having the incorrect
length, possibly resulting in loss of system redundancy, or
generation of smoke and smell, or loss of power plant fire
protection function.
To address this potential unsafe condition, Pilatus issued the
[service bulletin] SB, providing instructions to improve the
electrical harness installations in the nose bay, cockpit, fuselage,
wing fairing and rear fuselage areas.
For the reason described above, this [EASA] AD requires
modification of the electrical harness installations.
The incorrect length wires are too short in length and do not have
appropriate slack, which could lead to wires being pulled loose from
the terminals during flight or ground operation. Generation of smell
refers to the smell from electrical arcing.
You may obtain further information by examining the MCAI in the AD
docket on the internet at https://www.regulations.gov by searching for
and locating Docket No. FAA-2020-0818.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Pilatus PC-24 Service Bulletin No. 91-001, dated
April 7, 2020. The service information specifies procedures necessary
to improve the electrical harness installation in the nose bay,
cockpit, avionics rack, fuselage, wing fairing, and rear fuselage. 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.
FAA's Determination and Requirements of the Proposed AD
This product has been approved by the aviation authority of another
country and is approved for operation in the United States. Pursuant to
our bilateral agreement with this State of Design Authority, it has
notified the FAA of the unsafe condition described in the MCAI and
service information referenced above. The FAA is proposing this AD
because the FAA evaluated all information and determined the unsafe
condition exists and is likely to exist or develop on other products of
the same type design.
Costs of Compliance
The FAA estimates that this proposed AD would affect
[Lt]Number_of_Aircraft[Gt] products of U.S. registry. The FAA also
estimates that it would take 20 work-hours per product to comply with
the requirements of this proposed AD. The average labor rate is $85 per
work-hour. Required parts would cost about [Lt]Inspect_Parts[Gt] per
product.
Based on these figures, the FAA estimates the cost of the proposed
AD on U.S. operators would be [Lt]Fleet_Cost[Gt], or $1,775 per
product.
According to the manufacturer, some of the costs of this AD may be
covered under warranty, thereby reducing the cost impact on affected
individuals. The FAA does not control warranty coverage for affected
individuals. As a result, the FAA has included all costs in this cost
estimate.
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) 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
[[Page 58004]]
under the criteria of the Regulatory Flexibility Act.
