14 CFR Part 39

[Docket No. FAA-2015-2775; Directorate Identifier 2015-CE-021-AD; 
Amendment 39-18277; AD 2015-19-15]

Airworthiness Directives; Pilatus Aircraft Ltd. Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for PILATUS 
AIRCRAFT LTD. Models PC-12, PC-12/45, and PC-12/47E airplanes. This AD 
results from mandatory continuing airworthiness information (MCAI) 
issued by an aviation authority of another country to identify and 
correct an unsafe condition on an aviation product. The MCAI describes 
the unsafe condition as a malfunction of the universal joint. We are 
issuing this AD to require actions to address the unsafe condition on 
these products.

DATES: This AD is effective November 3, 2015.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of November 3, 
2015.

ADDRESSES: You may examine the AD docket on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2015-

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: http://www.regulations.gov/#!documentDetail;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:
     Are consistent with the intent that was proposed in the 
NPRM (80 FR 40949, July 14, 2015) for correcting the unsafe condition; 
and
     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.

    You may examine the AD docket on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2015-
2775; or in person at the Docket Management Facility between 9 a.m. and

(telephone (800) 647-5527) is in the ADDRESSES section. Comments will

(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

doug.rudolph@faa.gov. Before using any approved AMOC on any airplane 
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
