was 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 improperly manufactured cockpit and cabin
evaporator filters installed during production on some PC-24 airplanes.
The FAA is issuing this AD to address the unsafe condition on these
products.

DATES: This AD is effective March 30, 2021.
    The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of March 30,
2021.

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 Pilatus Model PC-24
airplanes with certain part-numbered evaporator filter assemblies
installed. The NPRM published in the Federal Register on November 23,
2020 (85 FR 74627). The NPRM was prompted by MCAI originated by the
European Union Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Union. EASA has issued EASA
AD No. 2020-0160, dated July 16, 2020 (referred to after this as ``the
MCAI''), to address the unsafe condition on Pilatus Model PC-24
airplanes. The MCAI states:

    An occurrence was reported where, during production, cockpit and
cabin evaporator filters were installed on some PC-24 aeroplanes,
which were not the proper parts for the affected configuration.
    This condition, if not corrected, could degrade the fire
retardant properties of the filters, possibly resulting in an
increase in smoke in the cockpit/cabin in case of electrical heater
over-temperature.
    To address this potential unsafe condition, Pilatus issued the
[service bulletin] SB to provide replacement instructions.
    For the reason described above, this AD requires replacement of
affected parts with serviceable parts, as defined in this [EASA] AD,
and prohibits (re) installation of affected parts.

    Due to a quality escape, the fire retardant used in the original
filters installed in production is not sufficient for the conditions in
this configuration, which is close to the heater and blowers.
    The MCAI can be found in the AD docket at https://www.regulations.gov by searching for and locating Docket No. FAA-2020-
0885.

Discussion of Final Airworthiness Directive

Comments

    The FAA received no comments on the NPRM or on the determination of
the costs.

Conclusion

    The FAA reviewed the relevant data 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. This AD is
adopted as proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Pilatus PC-24 Service Bulletin No. 21-006, dated
April 3, 2020. This service information specifies procedures replace
the cockpit and cabin evaporator filters with new filters contained in
a modification kit. 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

    This AD applies to airplanes with a defective filter installed,
whereas the EASA AD applies to airplanes that do not have the
modification kit, which was installed in production. This AD identifies
the individual part numbers (P/Ns) of the defective filters to address
any airplanes that may have had a modification kit filter replaced with
a defective filter in the field before this AD becomes effective. This
AD also applies to airplanes with a filter where the P/N is unknown.
Pilatus advises that the defective filters can only be identified by
their packing documents,

as they do not have a permanent P/N marked on the actual part. The new
filters in the modification kit do have a permanent marking on the
frame of the actual part.

Costs of Compliance

    The FAA estimates that this AD will affect 36 airplanes of U.S.
registry. The FAA also estimates that it would take 2.5 work-hours per
product to comply with the requirements of this AD. The average labor
rate is $85 per work-hour. Required parts would cost about $575 per
product, if all 4 filters would need to be replaced.
    Based on these figures, the FAA estimates the cost of this AD on
U.S. operators to be $28,350, or $787.50 per product.
    The FAA has included all costs in this cost estimate. According to
the manufacturer, however, some of the costs of this AD may be covered
under warranty, thereby reducing the cost impact on affected operators.

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.

ENVIRONMENTAL PROTECTION AGENCY

[EPA-HQ-OPPT-2012-0613; FRL-9360-1]

Certain New Chemicals; Receipt and Status Information

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice.

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

SUMMARY: The Toxic Substances Control Act (TSCA) requires any person
who intends to manufacture (defined by statute to include import) a new
chemical (i.e., a chemical not on the TSCA Chemical Substances
Inventory (TSCA Inventory)) to notify EPA and comply with the statutory
provisions pertaining to the manufacture of new chemicals. In addition
under TSCA, EPA is required to publish in the Federal Register a notice
of receipt of a premanufacture notice (PMN) or an application for a
test marketing exemption (TME), and to publish in the Federal Register
periodic status reports on the new chemicals under review and the
receipt of notices of commencement (NOC) to manufacture those
chemicals. This document, which covers the period from July 23, 2012 to
August 03, 2012, and provides the required notice and status report,
consists of the PMNs and TMEs, both pending or expired, and the NOC to
manufacture a new chemical that the Agency has received under TSCA
section 5 during this time period.

DATES: Comments identified by the specific PMN number or TME number,
must be received on or before September 28, 2012.

ADDRESSES: Submit your comments, identified by docket identification
(ID) number EPA-HQ-OPPT-2012-0613, and the specific PMN number or TME
number for the chemical related to your comment, by one of the
following methods:
     Federal eRulemaking Portal: http://www.regulations.gov.
Follow the on-line instructions for submitting comments.
     Mail: Document Control Office (7407M), Office of Pollution
Prevention and Toxics (OPPT), Environmental Protection Agency, 1200
Pennsylvania Ave. NW., Washington, DC 20460-0001.
     Hand Delivery: OPPT Document Control Office (DCO), EPA
East Bldg., Rm. 6428, 1201 Constitution Ave. NW., Washington, DC. The

boxed information.
    Instructions: EPA's policy is that all comments received will be
included in the docket without change and may be made available on-line
at http://www.regulations.gov, including any personal information
provided, unless the comment includes information claimed to be
Confidential Business Information (CBI) or other information whose
disclosure is restricted by statute. Do not submit information that you
consider to be CBI or otherwise protected through regulations.gov or
email. The regulations.gov Web site is an ``anonymous access'' system,
which means EPA will not know your identity or contact information
unless you provide it in the body of your comment. If you send an email
comment directly to EPA without going through regulations.gov, your
email address will be automatically captured and included as part of
the comment that is placed in the docket and made available on the
Internet. If you submit an electronic comment, EPA recommends that you
include your name and other contact information in the body of your
comment and with any disk or CD-ROM you submit. If EPA cannot read your
comment due to technical difficulties and cannot contact you for
clarification, EPA may not be able to consider your comment. Electronic
files should avoid the use of special characters, any form of
encryption, and be free of any defects or viruses.
    Docket: All documents in the docket are listed in the docket index
available at http://www.regulations.gov. Although listed in the index,
some information is not publicly available, e.g., CBI or other
information whose disclosure is restricted by statute. Certain other
material, such as copyrighted material, will be publicly available only
in hard copy. Publicly available docket materials are available
electronically at http://www.regulations.gov, or, if only available in
hard copy, at the OPPT Docket. The OPPT Docket is located in the EPA
Docket Center (EPA/DC) at Rm. 3334, EPA West Bldg., 1301 Constitution
Ave. NW., Washington, DC. The EPA/DC Public Reading Room hours of
operation are 8:30 a.m. to 4:30 p.m., Monday through Friday, excluding
legal holidays. The telephone number of the EPA/DC Public Reading Room
is<PHONE_NUMBER>, and the telephone number for the OPPT Docket is
(202) 566-0280. Docket visitors are required to show photographic
identification, pass through a metal detector, and sign the EPA visitor
log. All visitor bags are processed through an X-ray machine and
subject to search. Visitors will be provided an EPA/DC badge that must
be visible at all times in the building and returned upon departure.

SUPPLEMENTARY INFORMATION:

I. General Information

A. Does this action apply to me?

    This action is directed to the public in general. As such, the
Agency has not attempted to describe the specific entities that this
action may apply to. Although others may be affected, this action
applies directly to the submitter of the PMNs addressed in this action.

B. What should I consider as I prepare my comments for EPA?

    1. Submitting CBI. Do not submit this information to EPA through
regulations.gov or email. Clearly mark the part or all of the
information that you claim to be CBI. For CBI information in a disk or
CD-ROM that you mail to EPA, mark the outside of the disk or CD-ROM as
CBI and then identify electronically within the disk or CD-ROM the
specific information that is claimed as CBI. In addition to one
complete version of the comment that includes information claimed as
CBI, a copy of the comment that does not contain the information
claimed as CBI must be submitted for inclusion in the public docket.
Information so marked will not be disclosed except in accordance with
procedures set forth in 40 CFR part 2.
    2. Tips for preparing your comments. When submitting comments,
remember to:
    i. Identify the document by docket ID number and other identifying
information (subject heading, Federal Register date and page number).
    ii. Follow directions. The Agency may ask you to respond to
specific questions or organize comments by referencing a Code of
Federal Regulations (CFR) part or section number.
    iii. Explain why you agree or disagree; suggest alternatives and
substitute language for your requested changes.

    iv. Describe any assumptions and provide any technical information
and/or data that you used.
    v. If you estimate potential costs or burdens, explain how you
arrived at your estimate in sufficient detail to allow for it to be
reproduced.
    vi. Provide specific examples to illustrate your concerns and
suggest alternatives.
    vii. Explain your views as clearly as possible, avoiding the use of
profanity or personal threats.
    viii. Make sure to submit your comments by the comment period
deadline identified.

II. Why is EPA taking this action?

    EPA classifies a chemical substance as either an ``existing''
chemical or a ``new'' chemical. Any chemical substance that is not on
EPA's TSCA Inventory is classified as a ``new chemical,'' while those
that are on the TSCA Inventory are classified as an ``existing
chemical.'' For more information about the TSCA Inventory go to: http://www.epa.gov/opptintr/newchems/pubs/inventory.htm. Anyone who plans to
manufacture or import a new chemical substance for a non-exempt
commercial purpose is required by TSCA section 5 to provide EPA with a
PMN, before initiating the activity. Section 5(h)(1) of TSCA authorizes
EPA to allow persons, upon application, to manufacture (includes
import) or process a new chemical substance, or a chemical substance
subject to a significant new use rule (SNUR) issued under TSCA section
5(a), for ``test marketing'' purposes, which is referred to as a test
marketing exemption, or TME. For more information about the
requirements applicable to a new chemical go to: http://ww.epa.gov/opt/newchems.
    Under TSCA sections 5(d)(2) and 5(d)(3), EPA is required to publish
in the Federal Register a notice of receipt of a PMN or an application
for a TME and to publish in the Federal Register periodic status
reports on the new chemicals under review and the receipt of NOCs to
manufacture those chemicals. This status report, which covers the
period from July 23, 2012 to August 03, 2012, consists of the PMNs
pending or expired, and the NOCs to manufacture a new chemical that the
Agency has received under TSCA section 5 during this time period.

III. Receipt and Status Reports

    In Table I. of this unit, EPA provides the following information
(to the extent that such information is not claimed as CBI) on the PMNs
received by EPA during this period: The EPA case number assigned to the
PMN, the date the PMN was received by EPA, the projected end date for
EPA's review of the PMN, the submitting manufacturer/importer, the
potential uses identified by the manufacturer/importer in the PMN, and
the chemical identity.

DEPARTMENT OF TRANSPORTATION

Federal Aviation Administration

Technical Standard Order (TSO)-C91a, Emergency Locator
Transmitters (ELTs)

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of cancellation of Technical Standard Order (TSO)-C91a,
Emergency Locator Transmitter (ELT) Equipment.

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

SUMMARY: This notice announces the FAA's cancellation of TSO-C91a,
Emergency Locator Transmitter (ELT) Equipment. The effect of the
cancelled TSO will result in no new TSO-C91a design or production
approvals being issued. Applicants wanting to apply for TSO
Authorization (TSOA) for new Emergency Locator Transmitters (ELTs)
after December 1, 2012, must seek authorization for TSO-C126a, 406 MHz
Emergency Locator Transmitter (ELT), or subsequent.

FOR FURTHER INFORMATION CONTACT: Mr. Albert Sayadian, AIR-130, Federal
Aviation Administration, 470 L'Enfant Plaza, Suite 4102, Washington, DC
20024. Telephone<PHONE_NUMBER>, fax<PHONE_NUMBER>, email to:

SUPPLEMENTARY INFORMATION:

Background

    On February 1, 2009 Cospas-Sarsat satellite system stopped
processing signals from 121.5 MHz ELTs and now only processes signals
from 406 MHz ELTs. The decision to discontinue processing of the 121.5
MHz signal was made by the International Cospas-Sarsat program with
guidance from the United Nations. This was made due to the problems
within the 121.5 MHz frequency band which inundated SAR authorities
with reports of poor accuracy and numerous false alerts, thus impacting
the effectiveness of lifesaving services.
    The 406 MHz ELT technology is an advance over the older 121.5 MHz
ELT technology. TSO-C126a ELT equipment is more accurate and reliable
than the 121.5 MHz ELT equipment. Examples of these improvements are:
(1) Global satellite coverage; (2) a unique beacon identification which
is required to be registered so that if an alert is activated the
rescue coordination center can confirm whether the distress is real,
who they are looking for, and where the search should begin; (3) 406
MHz ELTs can be received by geostationary satellites which are always
visible and provide instantaneous alerting, and (4) increased position
accuracy which reduces the search area to less than two nautical miles
in radius. Additionally, 406 MHz ELTs can optionally include a GPS
position which can potentially reduce the search area to within 100
meters of the accident site.
    The performance and benefits of TSO-C126a equipment surpasses TSO-
C91a equipment. The 406 MHz technology is mature and prevalent in the
ELT market today. New TSO authorizations for ELTs should be
accomplished to TSO-C126a, or subsequent, thus the FAA is canceling
TSO-C91a.

Comments

    On January 11, 2012, a notice was published in the Federal Register
which requested comments on the cancellation of TSO-C91a (77 FR 1779).
    The FAA received comments from four organizations in response to
the Federal Register Notice. Comments from Cobham Beacon Products were
comprised of several questions. The first question regarded
permissibility of minor and major changes to existing TSO-C91a designs.
In response, minor changes to an existing TSO-C91a ELT design will
still be allowed in accordance with Title 14 of the Code of Federal
Regulation (14 CFR) 21.611(a), however, after December 1, 2012, a major
change that is extensive enough to require issuance of a new ELT TSO
authorization will have to meet the minimum performance standards
contained in TSO-C126a. Cobham's second question requested
clarification on repair and overhaul of TSO-C91a ELTs. The FAA
clarifies that repair and overhaul of TSO-C91a articles will continue
to be permissible. Cobham's third question involved permissibility of
continued installation of TSO-C91a ELTs. The FAA reiterates that
articles with previous TSO-C91a authorizations may still be produced,
sold, and installed. Cobham also inquired if the FAA will update 14 CFR
Sec.  91.207 to exclude TSO-C91a equipment if the Federal Communication
Commission (FCC) changes the rules governing the 121.5 MHz frequency.
The FAA can not comment on future FCC actions, however at this time the
FAA has no plans to revise 14 CFR 91.207.
    The second commenter, Astronics DME Corporation, provided two
comments. First, Astronics commented that cancellation of TSO-C91a
eliminates procedural access to the TSO requirements of 14 CFR 21,
Subpart O when a major change to the TSO's article is required. Under
14 CFR Part 21, a major change requires the TSO authorization holder to
apply for a new TSO authorization utilizing the latest revision of the
TSO. Major changes to TSO-C91a articles will be accepted when applied
for utilizing the latest revision of TSO-C126.
    Astronics also commented that elimination of satellite detection on
the 121.5 MHz frequency is not sufficient justification for TSO-C91a
cancellation. The FAA acknowledges that the 121.5 MHz ELT signal is
still monitored in many cases and provides limited search and rescue
functionality. However, TSO-C126a is a more mature standard, and the
406 MHz signal provides satellite detection, which enhances search and
rescue efforts. Because the 121.5 MHz ELT continues to provide this
basic functionality, the TSO-C91a ELTs can continue to be used to meet
14 CFR Sec.  91.207, however because a more mature standard is
available, it is appropriate to require new ELTs designs to meet the
standards of TSO-C126a, or subsequent.
    Astronics also commented that the TSO-C126a requirement to include
a 121.5 MHz homing beacon in the 406 MHz ELT should be modified to
allow manufacturers to include a GPS locator instead of the 121.5
homing beacon. The FAA acknowledges the benefits of including GPS
position with the 406 MHz ELT transmission, and encourages this
optional capability. However, this action is canceling TSO-C91a, and is
not modifying TSO-C126a.
    The General Aviation Manufacturers Association (GAMA) and the
Aircraft Owners and Pilots Association (AOPA) both provided comments
that they do not oppose the TSO-C91a cancelation, but that they would
oppose any future retrofit requirement. Both organizations requested
the FAA reiterate that cancelation of TSO-C91a does not impact the
continued production of articles with an existing TSO authorization nor
impact the sale, installation, or the use of 121.5 MHz ELTs to comply
with 14 CFR 91.207.
    The General Aviation Manufacturers Association (GAMA) also
conducted a survey of the manufacturers of general aviation aircraft
and determined that all current production airplanes include dual or
tri-band ELTs. Additionally, these dual or tri-band ELTs have been
installed in new production airplanes for over the past 5-years.
    The FAA reiterates in this final notice that cancelation of TSO-
C91a does not affect production under an existing TSO authorization.
Articles produced under an existing TSO-C91a authorization can still be
installed according to existing airworthiness approvals and
applications for new installation approvals will still be processed.
This

action does not impact operation of TSO-C91a ELTs, and these ELTs will
continue to satisfy the 14 CFR 91.207 ELT equipage requirement.
    GAMA also commented that the FAA should reconsider the ELT
operational mandate as newer technology, such as ADS-B, becomes more
commonplace. The FAA has determined that the ADS-B system currently
cannot replace the ELT function. The ADS-B system is not required to be
crashworthy and, thus, may not be operable or able to transmit
following an aircraft accident. Additionally, current search-and-rescue
technology is not compatible with ADS-B operations because ELTs
broadcast on 121.5 or 406 MHz (not 1090 or 978 MHz). The FAA recognizes
the value of a ground application that could allow for timely and
accurate flight tracking of downed aircraft and is evaluating this
capability separate from this action.

Conclusion

    TSO-C91a is canceled effective December 1, 2012. Manufacturers
applying for new ELT technical standard order authorizations after
December 1, 2012 must use TSO-C126a, or a subsequent ELT technical
standard order.
