Abstract
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
<a href="http://regulations.gov">regulations.gov</a>, 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:
<bullet> Model G-164A airplanes with STC No. SA7769SW, SA7966SW, or
SA8720SW installed; and
<bullet> 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
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
Installation of secondary retention 4 work-hours x $85 per $1,000 $1,340 $268,000
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:
