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 Pilatus Aircraft Ltd. Models
PC–6, PC–6/350, PC–6/350–H1, PC–6/
350–H2, PC–6/A, PC–6/A–H1, PC–6/A–
H2, PC–6/B–H2, PC–6/B1–H2, PC–6/
B2–H2, PC–6/B2–H4, PC–6/C–H2, PC–
6/C1–H2, PC–6–H1, and PC–6–H2
airplanes. The NPRM was published in
the Federal Register on April 5, 2019
(84 FR 13571). The NPRM proposed to
correct an unsafe condition for the
specified products and was based on
MCAI AD No. 2018–0235, dated
November 5, 2018, issued by the
European Aviation Safety Agency
(EASA), which is the Technical Agent
for the Member States of the European
Community. The MCAI states:
During a recent overhaul, two new flap
actuators were found to have taper pins
installed that, apparently, had not been
swaged. Investigation results identified that
the taper pins had been incorrectly swaged
during the manufacturing process.
This condition, if not detected and
corrected, could lead to loss of one or both
taper pins, consequent asymmetric flap
deployment or flap surface flutter, possibly
resulting in loss of control of the aeroplane.
To address this potential unsafe condition,
Pilatus issued the [service bulletin] SB to
provide inspection instructions.
For the reason described above, this
[EASA] AD requires a one-time inspection of
the taper pins of the affected parts for correct
installation and, depending on findings,
accomplishment of applicable corrective
action(s). This [EASA] AD also requires
inspection of, and, depending on findings,
corrective action(s) on, affected parts held as
spare, prior to installation.
The MCAI can be found in the AD
docket on the internet at: https://
www.regulations.gov/docket?D=FAA2019-0240.

Comments
The FAA gave the public the
opportunity to participate in developing
this AD. The FAA received one
comment from Richart Ruddie, who
supported the NPRM.
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.
Conclusion
The FAA reviewed the relevant data,
considered the comment received, and
determined that air safety and the
public interest require adopting the AD
as proposed.
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.
Related Service Information Under 1
CFR Part 51
The FAA reviewed Pilatus Aircraft
Ltd. PC–6 Service Bulletin No. 27–005,
dated July 2, 2018. The service
information contains procedures for
removing and inspecting the flap
actuator assemblies and pushrod
assemblies, modifying or replacing the
taper pins if necessary, and reinstalling
the assemblies. 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.
Costs of Compliance
The FAA estimates that this AD will
affect 30 products of U.S. registry. The
FAA also estimates that it would take
about 12 work-hours per product to
comply with the basic inspection
requirements of this AD. The average
labor rate is $85 per work-hour.
Based on these figures, the FAA
estimates the cost of this AD on U.S.
operators to be $30,600, or $1,020 per
product.
In addition, the FAA estimates that
any necessary follow-on modification or
replacement actions would require parts
costing $30,000, for a cost of $1,000 per
product. The FAA has no way of
determining the number of products
that may need these actions.
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

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 Pilatus Aircraft Ltd.
Models PC-6, PC-6/350, PC-6/350-H1, PC-6/350-H2, PC-6/A, PC-6/A-H1, PC-
6/A-H2, PC-6/B-H2, PC-6/B1-H2, PC-6/B2-H2, PC-6/B2-H4, PC-6/C-H2, PC-6/
C1-H2, PC-6-H1, and PC-6-H2 airplanes. The NPRM was published in the
Federal Register on April 5, 2019 (84 FR 13571). The NPRM proposed to
correct an unsafe condition for the specified products and was based on
MCAI AD No. 2018-0235, dated November 5, 2018, issued by the European
Aviation Safety Agency (EASA), which is the Technical Agent for the
Member States of the European Community. The MCAI states:
During a recent overhaul, two new flap actuators were found to
have taper pins installed that, apparently, had not been swaged.
Investigation results identified that the taper pins had been
incorrectly swaged during the manufacturing process.
This condition, if not detected and corrected, could lead to
loss of one or both taper pins, consequent asymmetric flap
deployment or flap surface flutter, possibly resulting in loss of
control of the aeroplane.
To address this potential unsafe condition, Pilatus issued the
[service bulletin] SB to provide inspection instructions.
For the reason described above, this [EASA] AD requires a one-
time inspection of the taper pins of the affected parts for correct
installation and, depending on findings, accomplishment of
applicable corrective action(s). This [EASA] AD also requires
inspection of, and, depending on findings, corrective action(s) on,
affected parts held as spare, prior to installation.
The MCAI can be found in the AD docket on the internet at: https://www.regulations.gov/docket?D=FAA-2019-0240.
Comments
The FAA gave the public the opportunity to participate in
developing this AD. The FAA received one comment from Richart Ruddie,
who supported the NPRM.
Conclusion
The FAA reviewed the relevant data, considered the comment
received, and determined that air safety and the public interest
require adopting the AD as proposed.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Pilatus Aircraft Ltd. PC-6 Service Bulletin No.
27-005, dated July 2, 2018. The service information contains procedures
for removing and inspecting the flap actuator assemblies and pushrod
assemblies, modifying or replacing the taper pins if necessary, and
reinstalling the assemblies. 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.
Costs of Compliance
The FAA estimates that this AD will affect 30 products of U.S.
registry. The FAA also estimates that it would take about 12 work-hours
per product to comply with the basic inspection requirements of this
AD. The average labor rate is $85 per work-hour.
Based on these figures, the FAA estimates the cost of this AD on
U.S. operators to be $30,600, or $1,020 per product.
In addition, the FAA estimates that any necessary follow-on
modification or replacement actions would require parts costing
$30,000, for a cost of $1,000 per product. The FAA has no way of
determining the number of products that may need these actions.
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
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.
Adoption of the Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA amends 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
