Federal Register / Vol. 85, No. 152 / Thursday, August 6, 2020 / Proposed Rules
§ 39.13
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
under the criteria of the Regulatory
Flexibility Act.

Discussion
The European Union Aviation Safety
Agency (EASA), which is the Technical
PO 00000
Frm 00020
Fmt 4702
Sfmt 4702
47717
Agent for the Member States of the
European Community, has issued EASA
AD No. 2019–0129, dated June 6, 2019
(referred to after this as ‘‘the MCAI’’), to
correct an unsafe condition for Pilatus
Aircraft Ltd. Models PC–12, PC–12/45,
PC–12/47, and PC–12/47E airplanes.
The MCAI states:
On the final assembly line, horizontal
stabilizer rear attachment bolts were detected
that had not received correct heat treatment.
Subsequent investigation determined that
certain parts, identified by FAUF, were
improperly manufactured and consequently
have reduced material properties.
This condition, if not corrected, could lead
to a fatigue failure of an affected part,
possibly resulting in loss of control of the
aeroplane.
To address this potential unsafe condition,
Pilatus issued the [service bulletin] SB to
provide inspection and replacement
instructions.
For the reason described above, this
[EASA] AD requires replacement of affected
parts, and prohibits (re)installation thereof.
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–
0745.
Related Service Information Under 1
CFR Part 51
The FAA reviewed Pilatus Aircraft
Ltd. PC–12 Service Bulletin No. 55–004,
dated March 29, 2019. The service
information contains procedures for
checking the rear attachment bolts for
the horizontal stabilizer and replacing
any defective bolts. 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 it 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 14 products of U.S.
registry. The average labor rate is $85
per work-hour.
E:\FR\FM\06AUP1.SGM
06AUP1
47718
Federal Register / Vol. 85, No. 152 / Thursday, August 6, 2020 / Proposed Rules
The FAA estimates that the proposed
actions would take 1.5 work-hours and
require parts costing $5,000, for a cost
of $5,127.50 per product and $71,785
for the U.S. operator fleet.
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
under the criteria of the Regulatory
Flexibility Act.

Discussion
The European Union Aviation Safety Agency (EASA), which is the
Technical Agent for the Member States of the European Community, has
issued EASA AD No. 2019-0129, dated June 6, 2019 (referred to after
this as ``the MCAI''), to correct an unsafe condition for Pilatus
Aircraft Ltd. Models PC-12, PC-12/45, PC-12/47, and PC-12/47E
airplanes. The MCAI states:
On the final assembly line, horizontal stabilizer rear
attachment bolts were detected that had not received correct heat
treatment. Subsequent investigation determined that certain parts,
identified by FAUF, were improperly manufactured and consequently
have reduced material properties.
This condition, if not corrected, could lead to a fatigue
failure of an affected part, possibly resulting in loss of control
of the aeroplane.
To address this potential unsafe condition, Pilatus issued the
[service bulletin] SB to provide inspection and replacement
instructions.
For the reason described above, this [EASA] AD requires
replacement of affected parts, and prohibits (re)installation
thereof.
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-2020-0745.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Pilatus Aircraft Ltd. PC-12 Service Bulletin No.
55-004, dated March 29, 2019. The service information contains
procedures for checking the rear attachment bolts for the horizontal
stabilizer and replacing any defective bolts. 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 it 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 14 products of
U.S. registry. The average labor rate is $85 per work-hour.
[[Page 47718]]
The FAA estimates that the proposed actions would take 1.5 work-
hours and require parts costing $5,000, for a cost of $5,127.50 per
product and $71,785 for the U.S. operator fleet.
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 under the criteria
of the Regulatory Flexibility Act.
