SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD)
for Allied Ag Cat Productions, Inc. (Allied Ag Cat) Model G-164A and G-
164B airplanes with certain supplemental type certificates (STCs)
installed. This proposed AD was prompted by an accident involving an
Allied Ag Cat Model G-164B airplane where the propeller pitch control
(PPC) linkage detached from the PPC of the engine and resulted in an
accident that significantly damaged the airplane and injured the pilot.
This proposed AD would require installing a secondary retention feature
(bolt, washer, and safety wire) on the PPC lever and the PPC assembly.
The FAA is proposing this AD to address the unsafe condition on these
products.

SUPPLEMENTARY INFORMATION:

Comments Invited

    The FAA invites you to send any written relevant data, views, or
arguments about this proposal. Send your comments to an address listed
under ADDRESSES. Include ``Docket No. FAA-2022-1656; Project Identifier
AD-2022-01081-A'' at the beginning of your comments. The most helpful
comments reference a specific portion of the proposal, explain the
reason for any recommended change, and include supporting data. The FAA
will consider all comments received by the closing date and may amend
this proposal because of those comments.
    Except for Confidential Business Information (CBI) as described in
the following paragraph, and other information as described in 14 CFR
11.35, the FAA will post all comments received, without change, to
regulations.gov, including any personal information you provide. The
agency will also post a report summarizing each substantive verbal
contact received about this NPRM.

Confidential Business Information

    CBI is commercial or financial information that is both customarily
and actually treated as private by its owner. Under the Freedom of
Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public
disclosure. If your comments responsive to this NPRM contain commercial
or financial information that is 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
Justin Carter, Aviation Safety Engineer, Fort Worth ACO Branch, FAA,
10101 Hillwood Parkway, Fort Worth, TX 76177. Any commentary that the
FAA receives which is not specifically designated as CBI will be placed
in the public docket for this rulemaking.

Background

    The FAA received a report of an accident involving an Allied Ag Cat
Model G-164 airplane where the PPC linkage detached from the PPC of the
engine. The pilot sustained serious injuries, and the airplane was
substantially damaged. The root cause was determined to be a lack of a
secondary retention feature for the PPC of the engine.
    This condition, if not addressed, could result in reduced control
of the airplane.
    Aircraft configurations for airplanes with the potential for this
condition to exist are as follows:
     Model G-164A airplanes with STC No. SA7769SW, SA7966SW, or
SA8720SW installed; and
     Model G-164B airplanes with STC No. SA7546SW, SA7966SW,
SA7987SW, or SA8720SW installed.

FAA's Determination

    The FAA is issuing this NPRM after determining that the unsafe
condition described previously is likely to exist or develop on other
products of these same type designs.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Honeywell Service Bulletin TPE331-72-2190,
Revision 0, dated December 21, 2011. This service information
identifies the affected PPC assemblies and applicable engines, and
specifies procedures for reworking the affected PPC assemblies to
incorporate a threaded hole in the splined end of the shouldered shaft.
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.

Other Related Service Information

    The FAA reviewed the Honeywell TPE331 Propeller Pitch Control Lever
letter, dated August 26, 2011, addressed to the original equipment
manufacturer (OEM). This letter informs the OEM of a report Honeywell
received about the TPE331 PPC lever shaft becoming detached from the
PPC assembly cam shaft and communicates the future development of a
Honeywell service bulletin (released as Honeywell Service Bulletin
TPE331-72-2190, Revision 0, dated December 21, 2011).

Proposed AD Requirements in This NPRM

    This proposed AD would require installing a secondary retention
feature (bolt, washer, and safety wire) on the PPC lever and the PPC
assembly.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would
affect 200 airplanes of U.S. registry.
    The FAA estimates the following costs to comply with this proposed
AD:

                                                 Estimated Costs

 feature.                              hour = $340.
----------------------------------------------------------------------------------------------------------------

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) Would not affect intrastate aviation in Alaska, and
    (3) Would 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:

Time).

ADDRESSES: The meetings will be conducted virtually. Please refer to
the SAB website at https://sab.epa.gov for details on how to access the
meetings.

FOR FURTHER INFORMATION CONTACT: Any member of the public who wants
further information concerning the public meetings may contact Dr.
Suhair Shallal, Designated Federal Officer (DFO), via telephone/voice
mail<PHONE_NUMBER>, or email at [email protected]. General
information concerning the SAB can be found on the EPA website at
http://sab.epa.gov.

SUPPLEMENTARY INFORMATION:
    Background: The SAB was established pursuant to the Environmental
Research, Development, and Demonstration Authorization Act (ERDDAA),
codified at 42 U.S.C. 4365, to provide independent scientific and
technical advice to the EPA Administrator on the scientific and
technical basis for agency positions and regulations. The SAB is a
Federal Advisory Committee chartered under the Federal Advisory

provisions of FACA and all appropriate SAB Staff Office procedural
policies. Pursuant to FACA and EPA policy, notice is hereby given that
the SAB per- and polyfluoroalkyl substances (PFAS) Review Panel (PFAS
Review Panel) will hold two public meetings to discuss their draft
report reviewing the EPA's four documents about (1) the health effects
data to inform the derivation of proposed Maximum Contaminant Level
Goals (MCLG) for PFOA and PFOS; (2) the analysis of health risk
reduction benefits of potential decreases in drinking water
concentrations of PFOA and PFOS and (3) approaches to assess the
cumulative risk among mixtures of PFAS.
    Technical Contacts: Any technical questions concerning EPA's
document titled, ``Proposed Approaches to the Derivation of a Draft
Maximum Contaminant Level Goal for Perfluorooctanoic Acid in Drinking
Water'' and ``Proposed Approaches to the Derivation of a Draft Maximum
Contaminant Level Goal for Perfluorooctanesulfonic Acid in Drinking

agenda and other meeting materials for each meeting will be placed on
the SAB website at http://sab.epa.gov.
    Procedures for Providing Public Input: Public comment for
consideration by EPA's federal advisory committees and panels has a
different purpose from public comment provided to EPA program offices.
Therefore, the process for submitting comments to a federal advisory
committee is different from the process used to submit comments to an
EPA program office.
    Federal advisory committees and panels, including scientific
advisory committees, provide independent advice to the EPA. Members of
the public can submit relevant comments pertaining to the committee's
charge or meeting materials. Input from the public to the SAB PFAS
Review Panel will have the most impact if it provides specific
scientific or technical information or analysis for the SAB PFAS Review
Panel to consider or if it relates to the clarity or accuracy of the
technical information. Members of the public wishing to provide comment
should contact the DFO directly.
    Oral Statements: In general, individuals or groups requesting an
oral presentation at a public meeting will be limited to three minutes.
Persons interested in providing oral statements on May 3, 2022, should
contact Dr. Sue Shallal, DFO, via email at the contact information
noted above by April 26, 2022, to be placed on the list of registered
speakers.
    Written Statements: Written statements will be accepted throughout
the advisory process; however, for timely consideration by SAB RFT
Review Panel members, statements should be received in the SAB Staff
Office by April 26, 2022, for consideration at the public meeting(s).
Written statements should be supplied to the DFO via email at the
contact information above. Submitters are requested to provide a signed
and unsigned version of each document because the SAB Staff Office does
not publish documents with signatures on its websites. Members of the
public should be aware that their personal contact information, if
included in any written comments, may be posted to the SAB website.
Copyrighted material will not be posted without explicit permission of
the copyright holder.
    Accessibility: For information on access or services for
individuals with disabilities, please contact Dr. Shallal at the phone
number or email address noted above, preferably at least ten days prior
to the meeting, to give the EPA as much time as possible to process
your request.
