Abstract
The FAA is adopting a new airworthiness directive (AD) for certain Textron Aviation Inc. (type certificate previously held by Raytheon Aircraft Company, Hawker Beechcraft Corporation, and Beechcraft Corporation) (Textron) Model 300, 300LW, B300, and B300C airplanes. This AD was prompted by a report of a timing issue where the yaw servo software can generate a motor position fault when the pilot applies rudder input at the same time the rudder boost system is activated, which disables the rudder boost function and leads to a reduced ability of the flight crew to maintain the safe flight and landing of the airplane or loss of control of the airplane. This AD requires updating the software version of the yaw servo. The FAA is issuing this AD to address the unsafe condition on these products.

SUPPLEMENTARY INFORMATION:
Background
Garmin informed the FAA of a problem during flight testing with the
Garmin International, Inc., G1000 integrated avionics system installed
on Textron Model 300, 300LW, B300, and B300C airplanes in accordance
with Supplemental Type Certificate (STC) No. SA01535WI-D. A timing
issue in the yaw servo software can generate a motor position fault
when the pilot applies rudder input at the same time the rudder boost
system is activated, which disables the rudder boost function.
The rudder boost system applies additional rudder force, using the
GSA 9000 yaw servo, following loss of an engine or significant loss of
thrust, which limits the rudder force required to maintain directional
control of the airplane. Loss of the rudder boost system without
warning before the moment rudder boost is needed could result in the
inability of the flight crew to maintain the safe flight and landing of
the airplane or loss of control of the airplane. The FAA is issuing
this AD to address the unsafe condition on these products.
FAA's Determination
The FAA is issuing this AD because the agency has determined the
unsafe condition described previously is likely to exist or develop in
other products of the same type design.
Related Service Information
The FAA reviewed Garmin STC Service Bulletin No. 21120, Revision A,
dated December 10, 2021. This service information specifies updating
the software version of the GSA 9000 yaw servo to version 2.14.
The FAA also reviewed Garmin Service Alert No. 21119, Revision A,
dated November 18, 2021; and Garmin Service Alert No. 21119, Revision
B, dated December 10, 2021. Revision A of this service information
advises owners and operators of the unsafe condition previously
described, while Revision B identifies the resolution by complying with
Garmin STC Service Bulletin No. 21120, Revision A, dated December 10,
2021.
[[Page 6405]]
AD Requirements
This AD requires updating the GSA 9000 yaw servo software to a
version that is not 2.13 or earlier.
Justification for Immediate Adoption and Determination of the Effective
Date
Section 553(b)(3)(B) of the Administrative Procedure Act (APA) (5
U.S.C. 551 et seq.) authorizes agencies to dispense with notice and
comment procedures for rules when the agency, for ``good cause,'' finds
that those procedures are ``impracticable, unnecessary, or contrary to
the public interest.'' Under this section, an agency, upon finding good
cause, may issue a final rule without providing notice and seeking
comment prior to issuance. Further, section 553(d) of the APA
authorizes agencies to make rules effective in less than thirty days,
upon a finding of good cause.
An unsafe condition exists that requires the immediate adoption of
this AD without providing an opportunity for public comments prior to
adoption. The FAA has found that the risk to the flying public
justifies foregoing notice and comment prior to adoption of this rule
because loss of rudder boost following an engine loss or significant
loss of thrust is likely to occur. This could result in the inability
of the flight crew to maintain the safe flight and landing of the
airplane and loss of control of the airplane. Many of the affected
airplanes operate more than 800 flight hours annually. Because of the
nature of the unsafe condition and the utilization rate of these
airplanes, the corrective actions to mitigate this unsafe condition
must be done within 100 flight hours or 3 months, whichever occurs
first after the effective date of this AD. Accordingly, notice and
opportunity for prior public comment are impracticable and contrary to
the public interest pursuant to 5 U.S.C. 553(b)(3)(B).
In addition, the FAA finds that good cause exists pursuant to 5
U.S.C. 553(d) for making this amendment effective in less than 30 days,
for the same reasons the FAA found good cause to forego notice and
comment.
Comments Invited
The FAA invites you to send any written data, views, or arguments
about this final rule. Send your comments to an address listed under
ADDRESSES. Include ``Docket No. FAA-2022-0088 and Project Identifier
AD-2022-00041-A'' at the beginning of your comments. The most helpful
comments reference a specific portion of the final rule, 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 final rule 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="https://www.regulations.gov">https://www.regulations.gov</a>, including any personal information you
provide. The agency will also post a report summarizing each
substantive verbal contact received about this final rule.
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 AD 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 AD, 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 AD. Submissions containing CBI should be sent to Phil
Petty, Aviation Safety Engineer, Wichita ACO Branch, FAA, 1801 Airport
Road, Wichita, KS 67209. Any commentary that the FAA receives which is
not specifically designated as CBI will be placed in the public docket
for this rulemaking.
Regulatory Flexibility Act
The requirements of the Regulatory Flexibility Act (RFA) do not
apply when an agency finds good cause pursuant to 5 U.S.C. 553 to adopt
a rule without prior notice and comment. Because FAA has determined
that it has good cause to adopt this rule without prior notice and
comment, RFA analysis is not required.
Costs of Compliance
The FAA estimates that this AD affects 300 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 airplane operators
----------------------------------------------------------------------------------------------------------------
Update yaw servo software........ 1 work-hour x $85 Not Applicable.......... $85 $25,500
per hour = $85.
----------------------------------------------------------------------------------------------------------------
The FAA has included all known costs in its 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, and
[[Page 6406]]
(2) Will not affect intrastate aviation in Alaska.
List of Subjects in 14 CFR Part 39

The Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA amends 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
0
2. The FAA amends Sec. 39.13 by adding the following new airworthiness
directive:
2022-03-23 Textron Aviation Inc. (type certificate previously held
by Raytheon Aircraft Company, Hawker Beechcraft Corporation, and
Beechcraft Corporation): Amendment 39-21941; Docket No. FAA-2022-
0088; Project Identifier AD-2022-00041-A.
(a) Effective Date
This airworthiness directive (AD) is effective February 22,
2022.
(b) Affected ADs
None.
(c) Applicability
This AD applies to Textron Aviation Inc. (type certificate
previously held by Raytheon Aircraft Company, Hawker Beechcraft
Corporation, and Beechcraft Corporation) Model 300, 300LW, B300, and
B300C airplanes, all serial numbers, certificated in any category,
that are equipped with a Garmin International, Inc., G1000
integrated avionics system installed in accordance with Supplemental
Type Certificate No. SA01535WI-D with GSA 9000 yaw servo software
version 2.13 or earlier.
(d) Subject
Joint Aircraft System Component (JASC) Code 2720, Rudder Control
System.
(e) Unsafe Condition
This AD was prompted by a report of a timing issue where the yaw
servo software can generate a motor position fault when the pilot
applies rudder input at the same time the rudder boost system is
activated, which disables the rudder boost. The FAA is issuing this
AD to prevent excessive rudder forces following loss of an engine or
significant loss of thrust. The unsafe condition, if not addressed,
could result in the inability of the flight crew to maintain the
safe flight and landing of the airplane and loss of control of the
airplane.
(f) Actions and Compliance
(1) Unless already done, within 100 hours time-in-service (TIS)
after the effective date of this AD or within 90 days after the
effective date of this AD, whichever occurs first, update the GSA
9000 yaw servo software to a version that is not 2.13 or earlier.
(2) As of the effective date of this AD, do not install yaw
servo software version 2.13 or earlier on the Garmin G1000
integrated avionics system on any airplane.
(g) Alternative Methods of Compliance (AMOCs)
(1) The Manager, Wichita ACO Branch, FAA, has the authority to
approve AMOCs for this AD, if requested using the procedures found
in 14 CFR 39.19. In accordance with 14 CFR 39.19, send your request
to your principal inspector or local Flight Standards District
Office, as appropriate. If sending information directly to the
manager of the certification office, send it to the attention of the
person identified in paragraph (h) of this AD.
(2) Before using any approved AMOC, notify your appropriate
principal inspector, or lacking a principal inspector, the manager
of the local flight standards district office/certificate holding
district office.
