Airworthiness Directives; Pilatus Aircraft Ltd. Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
certain Pilatus Aircraft Ltd. (Pilatus) Model PC-12, PC-12/45, PC-12/
47, and PC-12/47E airplanes. This AD is prompted by 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 insufficient grounding of the vapor cycle cooling system
(VCCS) compressor/condenser. This AD requires inspecting the power
return and chassis grounding cable attachment points at frame 37,
including the attachment parts, and depending on the inspection
results, corrective action. This AD also requires modifying the
installation of the VCCS compressor/condenser power return cables and
installing an additional isolated VCCS chassis ground cable. The FAA is
issuing this AD to address the unsafe condition on these products.

DATES: This AD is effective July 5, 2023.
    The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of July 5,
2023.

SUPPLEMENTARY INFORMATION:

Background

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 by adding an AD that would apply to certain serial-numbered
Pilatus Model PC-12, PC-12/45, PC-12/47, and PC-12/47E airplanes. The
NPRM published in the Federal Register on February 27, 2023 (88 FR
12273). The NPRM was prompted by AD 2022-0212, dated October 18, 2022
(referred to after this as ``the MCAI''), issued by the European Union
Aviation Safety Agency (EASA), which is the Technical Agent for the
Member States of the European Union.
    The MCAI was prompted by a reported occurrence of a burning odor
coming from the air conditioning vents during the climb phase of a
Pilatus Model PC-12/47E airplane. An investigation identified that
insufficient grounding of the VCCS compressor/condenser at frame 37
resulted in severe heat damage to the baseplate and adjacent metal
support structure. It was determined that this condition may occur on
airplanes equipped in production with the large oxygen bottle installed
on the right-hand side of the rear fuselage. To address the unsafe
condition, the MCAI requires a one-time inspection of the power return
and chassis grounding cable attachment point at frame 37, including the
attachment parts, and modification of the installation of the VCCS.
    In the NPRM, the FAA proposed to require a one-time inspection of
the power return and chassis grounding cable attachment point at frame
37, including the attachment parts, and modification of the
installation of the VCCS. This condition, if not addressed, could, in
the case of damage to the oxygen supply line, lead to an uncontrolled
fire with damage to the airplane and injury to the occupants. The FAA
is issuing this AD to address the unsafe condition on these products.
    You may examine the MCAI in the AD docket at regulations.gov under
Docket No. FAA-2023-0421.

Discussion of Final Airworthiness Directive

Comments

    The FAA received a comment from the Air Line Pilots Association,
International (ALPA), who supported the NPRM without change. In
addition, an individual commenter submitted a comment to the docket,
but did not comment on the proposed required actions or the
determination of the costs in the NPRM.

Conclusion

    These products have been approved by the aviation authority of
another country and are approved for operation in the United States.
Pursuant to the FAA's bilateral agreement with this State of Design
Authority, it has notified the FAA of the unsafe condition described in
the MCAI referenced above. The FAA reviewed the relevant data,
considered the comment received, and determined that air safety
requires adopting this AD as proposed. Accordingly, the FAA is issuing
this AD to address the unsafe condition on these products. Except for
minor editorial changes, this AD is adopted as proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Pilatus PC-12 Service Bulletin 21-016, dated
August 15, 2022, which specifies procedures for inspecting the power
return and chassis grounding cable attachment point on the airframe at
frame 37, including the attachment parts, modifying the installation of
the VCCS compressor/condenser power return cables, and installing an
additional isolated VCCS chassis ground cable. This service bulletin
also specifies contacting Pilatus if any damage is found.
    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 ADDRESSES.

Differences Between This AD and the MCAI

    The MCAI requires contacting the manufacturer for approved
corrective action instructions if any discrepancy is found during the
inspection. This AD requires contacting either the Manager,
International Validation Branch, FAA; EASA; or Pilatus's EASA Design
Organization Approval (DOA). If approved by the DOA, the approval must
include the DOA-authorized signature.

Costs of Compliance

    The FAA estimates that this AD affects 8 airplanes of U.S.
registry.
    The FAA estimates the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                Cost per      Cost on U.S.
            Action                        Labor cost               Parts cost         product        operators

                                $255.
Modify.......................  5 work-hours x $85 per hour =    $667............           1,092           8,736
                                $425.
----------------------------------------------------------------------------------------------------------------

    The repair instructions that may be needed as a result of the
inspection could vary significantly from airplane to airplane. The FAA
has no data to determine the costs to accomplish the repair or the
number of airplanes that would need this repair.

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.

I. The State's Submittal

A. What rule did the State submit?

    Table 1 lists the rule addressed by this proposal with the dates
that it was adopted by the local air agency and submitted by the
California Air Resources Board (CARB).

                                            Table 1--Submitted Rules
----------------------------------------------------------------------------------------------------------------
            Local agency                Rule No.              Rule title              Adopted        Submitted

SJVUAPCD...........................            4601  Architectural Coatings.....        12/17/09         5/17/10
----------------------------------------------------------------------------------------------------------------

    On June 8, 2010, EPA determined that the submittal for SJVUAPCD
Rule 4601 met the completeness criteria in 40 CFR part 51, Appendix V,
which must be met before formal EPA review.

B. Are there other versions of this rule?

    We finalized a limited approval/limited disapproval on an earlier
version of Rule 4601 into the SIP on 1/2/04 (69 FR 34). No versions
were adopted since then besides the 12/17/09 version.

C. What is the purpose of the submitted rule revision?

    VOCs help produce ground-level ozone and smog, which harm human
health and the environment. Section 110(a) of the CAA requires States
to submit regulations that control VOC emissions. Rule 4601 limits VOC
emissions during architectural coating, storage and clean-up
operations. EPA's technical support document (TSD) has more information
about this rule.

II. EPA's Evaluation and Action

A. How is EPA evaluating the rule?

    Generally, SIP rules must be enforceable (see section 110(a) of the
Act), must require Reasonably Available Control Technology (RACT) for
each category of sources covered by a Control Techniques Guidelines
(CTG) document as well as each major source in nonattainment areas (see
sections 182(a)(2) and (b)(2)), and must not relax existing
requirements (see sections 110(l) and 193). The SJVUAPCD regulates an
ozone nonattainment area (see 40 CFR part 81), but Rule 4601 does not
regulate major sources, so Rule 4601 need not fulfill RACT.
    Guidance and policy documents that we use to evaluate
enforceability and other requirements consistently include the
following:
    1. ``Issues Relating to VOC Regulation Cutpoints, Deficiencies, and
Deviations,'' EPA, May 25, 1988 (the Bluebook).
    2. ``Guidance Document for Correcting Common VOC & Other Rule
Deficiencies,'' EPA Region 9, August 21, 2001 (the Little Bluebook).
    3. Control of Volatile Organic Emissions from Existing Stationary
Sources, Volume I: Control Methods for Surface Coating Operations (EPA-
450/2-76-028, 11/76, NTIS PB-260-386).
    4. National VOC Emission Standards for Architectural Coatings (40
CFR 59 Subpart D, 9/11/98).
    5. Technical Review Group's Proposed Architectural Coatings SCM
(CARB, 1989).
    6. Suggested Control Measure for Architectural Coatings (CARB,
2000).

B. Does the rule meet the evaluation criteria?

    We believe this rule is consistent with the relevant policy and
guidance regarding enforceability, RACT, and SIP relaxations. The TSD
has more information on our evaluation.

C. EPA Recommendations To Further Improve the Rule

    The TSD describes one additional rule revision that we recommend
for the next time the local agency modifies the rule but is not
currently the basis for rule disapproval.

D. Public Comment and Final Action

    Because EPA believes the submitted rule fulfills all relevant
requirements, we are proposing to fully approve it as described in
section 110(k)(3) of the Act. We will accept comments from the public
on this proposal for the next 30 days. Unless we receive convincing new
information during the comment period, we intend to publish a final
approval action that will incorporate this rule into the federally
enforceable SIP.

III. Statutory and Executive Order Reviews

    Under the Clean Air Act, the Administrator is required to approve a
SIP submission that complies with the provisions of the Act and
applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a).
Thus, in reviewing SIP submissions, EPA's role is to approve State
choices, provided that they meet the criteria of the Clean Air Act.
Accordingly, this action merely approves State law as meeting Federal
requirements and does not impose additional requirements beyond those
imposed by State law. For that reason, this action:
     Is not a ``significant regulatory action'' subject to
review by the Office of Management and Budget under Executive Order
12866 (58 FR 51735, October 4, 1993);
     Does not impose an information collection burden under the
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
     Is certified as not having a significant economic impact
on a substantial number of small entities under the Regulatory
Flexibility Act (5 U.S.C. 601 et seq.);

     Does not contain any unfunded mandate or significantly or
uniquely affect small governments, as described in the Unfunded
Mandates Reform Act of 1995 (Pub. L. 104-4);
     Does not have Federalism implications as specified in
Executive Order 13132 (64 FR 43255, August 10, 1999);
     Is not an economically significant regulatory action based
on health or safety risks subject to Executive Order 13045 (62 FR
19885, April 23, 1997);
     Is not a significant regulatory action subject to
Executive Order 13211 (66 FR 28355, May 22, 2001);
     Is not subject to requirements of Section 12(d) of the
National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272
note) because application of those requirements would be inconsistent
with the Clean Air Act; and
     Does not provide EPA with the discretionary authority to
address disproportionate human health or environmental effects with
practical, appropriate, and legally permissible methods under Executive
Order 12898 (59 FR 7629, February 16, 1994).

In addition, this rule does not have tribal implications as specified
by Executive Order 13175 (65 FR 67249, November 9, 2000), because the
SIP is not approved to apply in Indian country located in the State,
and EPA notes that it will not impose substantial direct costs on
tribal governments or preempt tribal law.

SUPPLEMENTARY INFORMATION:

I. General Information

A. Background

    Section 108 (a) of the Clean Air Act directs the EPA Administrator
to identify certain pollutants which ``may reasonably be anticipated to
endanger public health and welfare'' and to issue air quality criteria
for them. These air quality criteria are to `` * * * accurately reflect
the latest scientific knowledge useful in indicating the kind and
extent of all identifiable effects on public health or welfare which
may be expected from the presence of [a] pollutant in the ambient air *
* *'' Under section 109 of the Act, EPA is then to establish National
Ambient Air Quality Standards (NAAQS) for each pollutant for which EPA
has issued criteria. Section 109(d) of the Act subsequently requires
periodic review and, if appropriate, revision of existing air quality
criteria to reflect advances in scientific knowledge on the effects of
the pollutant on public health and welfare. EPA is also to revise the
NAAQS, if appropriate, based on the revised criteria.
    Ozone is one of six ``criteria'' pollutants for which EPA has
established air quality criteria and NAAQS. On September 26, 2000 (65
FR 57810), EPA formally initiated its current review of the criteria
and NAAQS for ozone, requesting the submission of recent scientific
information on specified topics. A draft Project Work Plan for a
revised Ozone AQCD, with preliminary outlines for the proposed
chapters, was released for public comment (66 FR 67524, December 31,
2001) and reviewed by the Clean Air Scientific Advisory Committee
(CASAC) of EPA's Science Advisory Board (68 FR 3527, January 24, 2003).
EPA later convened a series of workshops to discuss draft sections and
chapters that had been developed

for revising the existing Ozone AQCD (68 FR 17365, April 9, 2003, and
68 FR 60369, October 22, 2003).
    In January 2005, EPA announced the availability of the First
External Review Draft of the revised Ozone AQCD for public review and
comments (70 FR 4850, January 31, 2005) and presented the draft to the
CASAC Ozone Review Panel on May 4-5, 2005. Taking into account public
and CASAC comments, EPA prepared and announced a Second External Review
Draft for public review and comment (70 FR 51810, August 31, 2005).
    At a public meeting in December 2005, EPA presented the Second
External Review Draft to the Clean Air Scientific Advisory Committee
(CASAC) for their review. Public comments and comments from the CASAC
Review Panel were considered in preparing the final Ozone AQCD
announced in this Federal Register notice.

Statutory Basis for, the Proposed Rule Change

1. Purpose
    ISE, LLC proposes to amend ISE Holdings' Certificate of
Incorporation and Bylaws to remove the requirement that the President
of the Company also be the Chief Executive Officer of the Company.
Currently, the ISE Holdings Bylaws require that the President of the
Company also be the Chief Executive Officer of the Company.\5\ The
Exchange believes that the proposed modification would provide the
Board of Directors of ISE Holdings with the flexibility to structure
management of the Company in a way that is most effective for
attracting and keeping the industry's most talented people, and in turn
provide the flexibility to attract and retain the best possible
management team for the Company and its stockholders.
---------------------------------------------------------------------------

    \5\ ISE Holdings Bylaws, Section 4.1.
---------------------------------------------------------------------------

2. Statutory Basis
    The basis under the Act for this proposed rule change is the

Act and to comply, and

(subject to any rule or order of the Commission pursuant to Section
17(d) \7\ or 19(g)(2) \8\ of the Act) to enforce compliance by its
members and persons associated with its members, with the provisions of
the Act, the rules and regulations thereunder, and the rules of the
exchange. The Exchange also believes this proposed rule change furthers
the objective of Section 6(b)(5) \9\ that an exchange have rules that,
among other things, are designed to remove impediments to and perfect
the mechanism for a free and open market and a national market system,
and, in general, to protect investors and the public interest.

Airworthiness Directives; Pratt & Whitney Canada Corp. Turboprop
Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD)
for all Pratt & Whitney Canada Corp. PT6A-34, -34B, -34AG, -114, and -
114A model turboprop engines. This proposed AD was prompted by several
reports of low-time fractures of compressor turbine (CT) blades
resulting in loss of power or in-flight shutdown of the engine. This
proposed AD would require replacement of certain CT vanes. This
proposed AD would also require removal from service of certain CT
blades when these blades have been operated with certain CT vanes. The
FAA is proposing this AD to address the unsafe condition on these
products.

DATES: The FAA must receive comments on this proposed AD by October 1,
2020.

ADDRESSES: You may send comments, using the procedures found in 14 CFR
11.43 and 11.45, by any of the following methods:

customarily treated as private, that you actually treat as private, and
that is relevant or responsive to this NPRM, it is important that you
clearly designate the submitted comments as CBI. Please mark each page
of your submission containing CBI as ``PROPIN.'' The FAA will treat
such marked submissions as confidential under the FOIA, and they will
not be placed in the public docket of this NPRM. Submissions containing
CBI should be sent to Barbara Caufield, Aerospace Engineer, ECO Branch,
FAA, 1200 District Avenue, Burlington, MA 01803. Any commentary that
the FAA receives which is not specifically designated as CBI will be
placed in the public docket for this rulemaking.

Background

    Transport Canada, which is the aviation authority for Canada, has
issued Canada AD CF 2019-30R1, dated December 17, 2019 (referred to
after this as ``the MCAI''), to address the unsafe condition on these
products. The MCAI states:

    There have been several reported events of low time CT blade
fractures resulting in power loss/In-flight shutdown (IFSD) on post
P&WC Service Bulletin (SB) 1669 configured PT6A-114 engines,
featuring new CMSX-6 CT blades. In addition, relatively low time
failures of Non-P&WC CT blades have also been reported on PT6A-34
and -114 series engines.
    In service data shows that these low time failures were reported
on engines that had CT vanes installed that were repaired in
accordance with repair specification number STI 72-50-254 held by
Southwest Turbine Inc. (STI). Most of the affected engines are
installed on single-engine powered aeroplanes and some events have
resulted in the loss of the aeroplane and fatalities.
    Dimensional checks and operational testing of the subject STI
repaired CT vane removed from an incident engine, revealed that it
did not conform to the engine manufacturer's CT vane type design
criteria. The noted variations and features in the STI repaired CT
vane can cause airflow distortion and subsequent aerofoil excitation
of the CT blades resulting in High Cycle Fatigue (HCF) failure of
the CT blades. Test data indicates that the stress levels induced in
CT blades by the adverse effect of subject airflow distortion
exceeds the design requirements for CMSX-6 CT blades.
    An IFSD or loss of power on a single-engine powered aeroplane
under certain conditions can lead to an unsafe condition as seen in
some past events. AD CF-2019-30 was issued on 19 August 2019 to
address the potential hazard of power loss/IFSD as a result of CT
blade failures on engines with CT vanes installed that were repaired
in accordance with repair specification number STI 72-50-254.
    This AD revision, CF-2019-30R1, is issued to update the
background information and to clarify the affected P&WC CT blade
Part Numbers (P/Ns).

    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-2020-0692.

FAA's Determination

    This product has been approved by the aviation authority of Canada
and is approved for operation in the United States. Pursuant to our
bilateral agreement with Canada, they have notified us of the unsafe
condition described in the MCAI and service information referenced
above. The FAA is issuing this NPRM because we evaluated all the
relevant information provided by Transport Canada and determined the
unsafe condition described previously is likely to exist or develop in
other products of the same type design.

Proposed AD Requirements

    This proposed AD would require replacement of certain CT vanes.
This proposed AD would also require removal from service of certain CT
blades when these blades have been operated with certain CT vanes.

Costs of Compliance

    The FAA estimates that this proposed AD affects 907 engines
installed on airplanes of U.S. registry. The FAA estimates that 63
engines will need to replace the CT vanes and CT blades.
    The FAA estimates the following costs to comply with this proposed
AD:

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.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

Southwest Turbine Inc. (STI) repair specification STI-72-50-254 and
replace with a non-STI-repaired CT vane.
    (ii) Remove from service any CMSX-6 CT blade that has been
operated on an affected engine with a CT vane repaired in accordance
with STI repair specification STI-72-50-254.
    (2) [Reserved]

(h) Installation Prohibition

    After the effective date of this AD, do not install on any
engine a CT vane that was repaired in accordance with repair
specification STI-72-50-254.

(i) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, ECO Branch, FAA, has the authority to approve
AMOCs for this AD, if requested using the procedures found in 14 CFR
