SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to adding an AD that would apply to PILATUS AIRCRAFT LTD. Model
PC-12, PC-12/45, and PC-12/47E airplanes. The NPRM was published in the
Federal Register on July 14, 2015 (80 FR 40949). The NPRM proposed to
correct an unsafe condition for the specified products and was based on
mandatory continuing airworthiness information (MCAI) originated by an
aviation authority of another country. The MCAI states:
A case of malfunctioning was reported of a universal joint
installed between the control tube assembly and the control column
on a PC-12/47E aeroplane.
Investigation determined that the malfunction was caused by an
incorrectly manufactured universal joint. Universal joints from the
same manufacturing batch were provided to operators between 01 March
2014 and 28 February 2015, and are thus potentially affected.
This condition, if not corrected, could lead to other cases of
malfunctioning of a universal joint, possibly resulting in reduced
control of the aeroplane.
To address this potential unsafe condition, Pilatus Aircraft
Ltd. issued Service Bulletin (SB) No. 27-022 to provide instructions
for replacement of the universal joints in the flight controls.
For the reason described above, this AD requires removal from
service of the potentially incorrectly manufactured universal joints.
The MCAI can be found in the AD docket on the Internet at: <a href="http://www.regulations.gov/#!documentDetail">http://www.regulations.gov/#!documentDetail</a>;D=FAA-2015-2775-0002.
Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM (80 FR 40949, July 14,
2015) or on the determination of the cost to the public.
Conclusion
We reviewed the relevant data and determined that air safety and
the public interest require adopting the AD as proposed except for
minor editorial changes. We have determined that these minor changes:
<bullet> Are consistent with the intent that was proposed in the
NPRM (80 FR 40949, July 14, 2015) for correcting the unsafe condition;
and
<bullet> Do not add any additional burden upon the public than was
already
[[Page 58343]]
proposed in the NPRM (80 FR 40949, July 14, 2015).
Related Service Information Under 1 CFR Part 51
We reviewed PILATUS AIRCRAFT LTD. PILATUS PC-12 Service Bulletin
No: 27-022, dated March 17, 2015. The service information describes
procedures for replacement of the universal joint on the aileron
control system. 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
of the AD.
Costs of Compliance
We estimate that this AD will affect 55 products of U.S. registry.
We also estimate that it would take about 3 work-hours per product to
comply with the basic requirements of this AD. The average labor rate
is $85 per work-hour. Required parts would cost about $1,000 per
product.
Based on these figures, we estimate the cost of the AD on U.S.
operators to be $69,025 or $1,255 per product.
According to the manufacturer, all of the costs of this AD may be
covered under warranty, thereby reducing the cost impact on affected
individuals. We do not control warranty coverage for affected
individuals. As a result, we have included all costs in our 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.
We are 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
We determined that 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 this AD:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866,
(2) Is not a ``significant rule'' under the DOT Regulatory Policies
and Procedures (44 FR 11034, February 26, 1979),
(3) Will not affect intrastate aviation in Alaska, and
(4) 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.

2775; or in person at the Docket Management Facility between 9 a.m. and

(g) Other FAA AD Provisions
The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager,
Standards Office, FAA, has the authority to approve AMOCs for this
AD, if requested using the procedures found in 14 CFR 39.19. Send

to which the AMOC applies, notify your appropriate principal
inspector (PI) in the FAA Flight Standards District Office (FSDO),
or lacking a PI, your local FSDO.
(2) Airworthy Product: For any requirement in this AD to obtain
corrective actions from a manufacturer or other source, use these
actions if they are FAA-approved. Corrective actions are considered
FAA-approved if they are approved by the State of Design Authority

estimated to be approximately 5 minutes per response, including the
time for reviewing instructions, completing and reviewing the
collection of information. All responses to this collection of
