SUPPLEMENTARY INFORMATION: As published, AD 2020-13-01, Amendment 39-
21146 (85 FR 41906, July 13, 2020), applies to all Daher Aircraft
Design, LLC (type certificate previously held by Quest Aircraft Design,
LLC), Model KODIAK 100 airplanes. AD 2020-13-01 requires a one-time
inspection to determine if an affected nose landing gear (NLG) fork is
installed, repetitive inspections of the affected NLG fork for cracks,
repetitive inspections of the shimmy damper bracket for looseness and
of the shimmy damper system for damaged components if an affected NLG
fork is installed, and rework/replacement of parts as necessary.
Need for the Correction
As published, the TC holder in the regulatory heading that
identifies the AD is incorrect. The heading incorrectly identified the
TC holder as ``Quest Aircraft Design, LLC.'' The correct TC holder is
Daher Aircraft Design, LLC (Type Certificate previously held by Quest
Aircraft Design, LLC).
Although no other part of the preamble or regulatory information
has been corrected, for clarity, the FAA is publishing the entire rule
in the Federal Register.
The effective date of this AD remains August 17, 2020.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Quest Aircraft Field Service Instruction FSI-147,
Revision 00, Release Date January 29, 2018, which provides instructions
for inspection and, if necessary, replacement of the NLG fork. The FAA
reviewed pages 32_110 and 32_111, section 3252, Shimmy Damper, Chapter
32, Landing Gear, of Quest Aircraft Company Kodiak 100 Maintenance
Manual, Revision No. 21, dated February 15, 2017, which contains
procedures for inspecting the shimmy damper system. The FAA also
reviewed Quest Aircraft Field Service Instruction FSI-146, Revision 00,
Release Date April 18, 2017, which provides instructions for modifying
the shimmy damper attach bracket. 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
the ADDRESSES section.
Good Cause for Adoption Without Prior Notice
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.'' Section 553(d)(3) of the APA requires that
agencies publish a rule not less than 30 days before its effective
date, except as otherwise provided by the agency for good cause found
and published with the rule.
Since this action only corrects the TC holder in a regulatory
heading, the FAA finds that notice and public comment under 5 U.S.C.
553(b) is unnecessary. For the same reason, the FAA finds that good
cause exists under 5 U.S.C. 553(d) for making this rule effective in
less than 30 days.
List of Subjects in 14 CFR Part 39

reference, Safety.
Adoption of the Correction
Accordingly, pursuant to the authority delegated to me by the
Administrator, the Federal Aviation Administration amends part 39 of
the Federal Aviation Regulations (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 [Corrected]
0
2. The FAA amends Sec. 39.13 by adding the following new airworthiness
directive (AD):
2020-13-01 Daher Aircraft Design, LLC (Type Certificate previously
held by Quest Aircraft Design, LLC): Amendment 39-21146; Docket No.
FAA-2018-0180; Project Identifier 2017-CE-043-AD.
(a) Effective Date
This airworthiness directive (AD) is effective August 17, 2020.
(b) Affected ADs
None.
(c) Applicability
This AD applies to Daher Aircraft Design, LLC (type certificate
previously held by Quest Aircraft Design, LLC), Model KODIAK 100
airplanes, all serial numbers, certificated in any category.
(d) Subject
Joint Aircraft System Component (JASC)/Air Transport Association
(ATA) of America Code 32, Landing Gear.
(e) Unsafe Condition
This AD was prompted by reports from the manufacturer of fatigue
cracks on the nose landing gear (NLG) fork. The FAA is issuing this
AD to detect and prevent fatigue cracking of the NLG fork. The
unsafe condition, if not corrected, could result in separation of
the NLG fork with consequent reduced control on landing. If the NLG
fork separates on an unimproved surface, the risk of the NLG digging
in and the airplane overturning on the ground increases.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Inspection for Type of NLG Fork
Within 25 hours time-in-service (TIS) after August 17, 2020 (the
effective date of this AD), inspect the airplane to determine if an
NLG fork part number (P/N) 100-410-7001 (type A) or an NLG fork P/N
100-410-7013 (type B) is installed. If you determine that an NLG
fork P/N 100-410-7013 (type B) is installed during the inspection,
no further action is required by this AD. If a review of the
maintenance records can identify the P/N NLG fork that is installed,
you may use a maintenance records review in lieu of inspecting the
airplane to determine if an NLG fork P/N 100-410-7001 (type A) or an
NLG fork P/N 100-410-7013 (type B) is installed.
(h) Inspection of the NLG Fork for Cracks
(1) If you determine that an NLG fork P/N 100-410-7001 (type A)
is installed during
[[Page 48104]]
the inspection required by paragraph (g) of this AD, within 25 hours
TIS after August 17, 2020 (the effective date of this AD) and
thereafter at intervals not to exceed 200 hours TIS, do a
fluorescent penetrant, dye penetrant, or open-hole eddy current
inspection of the NLG fork for cracks by following section 5.
Instructions in Quest Aircraft Field Service Instruction FSI-147,
Revision 00, Release Date January 29, 2018.
(2) If you find any cracks of the NLG fork during any inspection
required by paragraph (h)(1) of this AD, before further flight,
replace the NLG fork with an NLG fork P/N 100-410-7013 (type B).
Replacement of the NLG fork with an NLG fork P/N 100-410-7013 (type
B) terminates the repetitive inspections required by paragraphs
(h)(1) and (i)(1) of this AD.
(i) Inspection of the Shimmy Damper Bracket
(1) If you have not replaced an NLG fork P/N 100-410-7001 (type
A) per the initial inspection and replacement requirements in
paragraph (h) of this AD, then within 25 hours TIS after August 17,
2020 (the effective date of this AD) and thereafter at intervals not
to exceed 200 hours TIS (until the NLG fork is replaced with a P/N
100-410-7013 (type B) fork), inspect the shimmy damper bracket for
looseness, and inspect the shimmy damper system for damaged (loose,
leaking, corroded, or worn) components, by following pages 32_110
and 32_111, section 3252, Shimmy Damper, found in Chapter 32,
Landing Gear, of Quest Aircraft Company Kodiak 100 Maintenance
Manual, Revision No. 21, dated February 15, 2017.
(2) If a loose shimmy damper bracket is found during any
inspection required by paragraph (i)(1) of this AD, rework the
shimmy damper bracket with interference-fit bolts by following Quest
Aircraft Field Service Instruction FSI-146, Revision 00, Release
Date April 18, 2017. Reworking the shimmy damper bracket with the
interference-fit bolts terminates the repetitive inspections
required by paragraph (i)(1) of this AD.
(3) If any other damaged components are found in the shimmy
damper system during any inspection required by paragraph (i)(1) of
this AD, before further flight, replace the damaged components.
(j) Optional Terminating Action
In lieu of the NLG fork and shimmy damper bracket inspections
required by paragraphs (h)(1) and (i)(1) of this AD, you may replace
the NLG fork P/N 100-410-7001 (type A) with an NLG fork P/N 100-410-
7013 (type B). This replacement terminates the inspection
requirements of this AD, and no further actions are required.
(k) Restriction of NLG Fork P/N 100-410-7001 (Type A) Installation
Once an NLG fork P/N 100-410-7013 (type B) is installed on an
airplane, do not install an NLG fork P/N 100-410-7001 (type A). If
an NLG fork P/N 100-410-7013 (type B) is removed from the airplane
for any reason (for example, to install floats), you must reinstall
an NLG fork P/N 100-410-7013 (type B) when operating with wheels.
(l) Alternative Methods of Compliance (AMOCs)
(1) The Manager, Seattle ACO Branch, FAA, has the authority to
approve AMOCs for this AD, if requested using the procedures found
