Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking
(NPRM).
AGENCY:
We propose to adopt a new
airworthiness directive (AD) for all
Quest Aircraft Design, LLC Model
KODIAK 100 airplanes. This proposed
AD was prompted by reports of cracks
found in certain nose landing gear forks.
This proposed AD would require a onetime inspection to determine if the
affected nose landing gear fork is
installed, repetitive inspections of the
affected nose landing gear fork for
cracks, repetitive inspections of the
shimmy damper bracket for looseness if
the affected nose landing gear fork is
installed, and rework/replacement of
parts as necessary. We are proposing
this AD to address the unsafe condition
on these products.
DATES: We must receive comments on
this proposed AD by April 23, 2018.

Discussion
We received reports from the
manufacturer of fatigue cracks on the
nose landing gear (NLG) fork on Quest
Aircraft Design, LLC Model KODIAK
PO 00000
Frm 00003
Fmt 4702

100 airplanes. In one report, the NLG
fork failed during landing. On
unimproved surfaces, the NLG shimmy
damper system can wear and loosen,
reducing the resistance of the nose gear
to shimmy. Shimmying puts side loads
on the NLG fork that it was not designed
for, which could cause fatigue cracks.
This condition, if not corrected, could
result in separation of the fork with
consequent reduced control on landing.
If the fork separates on an unimproved
surface, the risk of the NLG digging in
and the airplane overturning on the
ground increases.
Related Service Information Under 1
CFR Part 51
We reviewed Quest Aircraft Field
Service Instruction FSI–147, Revision
00 (not dated), which provides
instructions for inspection and, if
necessary, replacement of the NLG fork.
We reviewed 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, which
describes procedures for inspecting the
shimmy damper system. We also
reviewed Quest Aircraft Field Service
Instruction FSI–146, Revision 00 (not
dated), 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.
FAA’s Determination
We are proposing this AD because we
evaluated all the relevant information
and determined the unsafe condition
described previously is likely to exist or
develop in other products of the same
type design.
Proposed AD Requirements
This proposed AD would require
accomplishing the actions specified in
the service information described
previously.
Costs of Compliance
We estimate that this proposed AD
affects 116 airplanes of U.S. registry.

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.
We are 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.
This AD is issued in accordance with
authority delegated by the Executive
Director, Aircraft Certification Service,
as authorized by FAA Order 8000.51C.
In accordance with that order, issuance
of ADs is normally a function of the
Compliance and Airworthiness
Division, but during this transition
period, the Executive Director has
delegated the authority to issue ADs
applicable to small airplanes, gliders,
balloons, airships, domestic business jet
transport airplanes, and associated
appliances to the Director of the Policy
and Innovation Division.

(a) Comments Due Date
We must receive comments by April 23,
2018.
(b) Affected ADs
None.
(c) Applicability
This AD applies to Quest Aircraft Design,

The Proposed Amendment
(e) Unsafe Condition
This AD was prompted by reports from the
manufacturer of fatigue cracks on the nose
landing gear (NLG) fork. We are 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
fork with consequent reduced control on
landing. If the fork separates on an
unimproved surface, the risk of the NLG
digging in and the airplane overturning on
the ground increases.
Accordingly, under the authority
delegated to me by the Administrator,
the FAA proposes to amend 14 CFR part
39 as follows:
(f) Compliance
Comply with this AD within the
compliance times specified, unless already
done.

action’’ under Executive Order 12866,
(2) Is not a ‘‘significant rule’’ under
the DOT Regulatory Policies and
Procedures (44 FR 11034, February 26,

Discussion
We received reports from the manufacturer of fatigue cracks on the
nose landing gear (NLG) fork on Quest Aircraft Design, LLC Model KODIAK
100 airplanes. In one report, the NLG fork failed during landing. On
unimproved surfaces, the NLG shimmy damper system can wear and loosen,
reducing the resistance of the nose gear to shimmy. Shimmying puts side
loads on the NLG fork that it was not designed for, which could cause
fatigue cracks. This condition, if not corrected, could result in
separation of the fork with consequent reduced control on landing. If
the fork separates on an unimproved surface, the risk of the NLG
digging in and the airplane overturning on the ground increases.
Related Service Information Under 1 CFR Part 51
We reviewed Quest Aircraft Field Service Instruction FSI-147,
Revision 00 (not dated), which provides instructions for inspection
and, if necessary, replacement of the NLG fork. We reviewed 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, which describes procedures
for inspecting the shimmy damper system. We also reviewed Quest
Aircraft Field Service Instruction FSI-146, Revision 00 (not dated),
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

FAA's Determination
We are proposing this AD because we evaluated all the relevant
information and determined the unsafe condition described previously is
likely to exist or develop in other products of the same type design.
Proposed AD Requirements
This proposed AD would require accomplishing the actions specified
in the service information described previously.
Costs of Compliance
We estimate that this proposed AD affects 116 airplanes of U.S.

based on the results of the proposed NLG fork type determination. We
have no way of determining the number of airplanes that might need
these inspections, replacements, and modifications:
On-Condition Costs
----------------------------------------------------------------------------------------------------------------
Cost per
Action Labor cost Parts cost product

Inspection of the NLG fork for 4 work-hours x $85 per Not applicable................... $340
cracks. hour = $340.
Replacement of the NLG fork........ 4 work-hours x $85 per $7,002.36........................ 7,342.36

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.
We are 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.
This AD is issued in accordance with authority delegated by the
Executive Director, Aircraft Certification Service, as authorized by
FAA Order 8000.51C. In accordance with that order, issuance of ADs is
normally a function of the Compliance and Airworthiness Division, but
during this transition period, the Executive Director has delegated the
authority to issue ADs applicable to small airplanes, gliders,
balloons, airships, domestic business jet transport airplanes, and
associated appliances to the Director of the Policy and Innovation
Division.
Regulatory Findings
We 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) Is not a ``significant rule'' under the DOT Regulatory Policies
and Procedures (44 FR 11034, February 26, 1979),
(3) Will not affect intrastate aviation in Alaska, and
(4) 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.
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:
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 (AD):
Quest Aircraft Design, LLC: Docket No. FAA-2018-0180; Product
Identifier 2017-CE-043-AD.
(a) Comments Due Date
We must receive comments by April 23, 2018.
(b) Affected ADs
None.
(c) Applicability
This AD applies to 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. We are 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 fork
with consequent reduced control on landing. If the 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 the effective date
of this AD, inspect the airplane to determine if a NLG fork part
number (P/N) 100-410-7001 (type A) or a NLG fork P/N 100-410-7013
(type B) is installed. If you determine that a NLG 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
positively identify the P/N NLG fork that is installed, you may use
a maintenance records review in lieu of
[[Page 9822]]
inspecting the airplane to determine if a NLG fork P/N 100-410-7001
(type A) or a NLG fork P/N 100-410-7013 (type B) is installed.
(h) Inspection of the NLG Fork for Cracks
(1) If you determine that a NLG fork P/N 100-410-7001 (type A)
is installed during the inspection required in paragraph (g) of this
AD, within 25 hours TIS after the effective date of this AD and
repetitively thereafter at intervals not to exceed 100 hours TIS, do
a fluorescent penetrant, dye penetrant, or open-hole eddy current
inspection of the NLG fork for cracks following section 5.
Instructions in Quest Aircraft Field Service Instruction FSI-147,
Revision 00 (not dated).
(2) If you find any cracks of the NLG fork during any inspection
required in paragraph (h)(1) of this AD, before further flight,
replace the NLG fork with a NLG fork P/N 100-410-7013 (type B)
following section 5. Instructions in Quest Aircraft Field Service
Instruction FSI-147, Revision 00 (not dated). Replacement of the NLG
fork with a NLG fork P/N 100-410-7013 (type B) terminates the
repetitive inspections required in paragraphs (h)(1) and (i)(1) of
this AD.
(i) Inspection of the Shimmy Damper Bracket
(1) If you have not replaced a 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 the
effective date of this AD and repetitively thereafter at intervals
not to exceed 100 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 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 in paragraph (i)(1) of this AD, rework the
shimmy damper bracket with interference-fit bolts following Quest
Aircraft Field Service Instruction FSI-146, Revision 00 (not dated).
Reworking the shimmy damper bracket with the interference-fit bolts
terminates the repetitive inspections required in paragraph (i)(1)
of this AD.
(3) If any other damaged (loose, leaking, corrosion, worn, etc.)
components are found in the shimmy damper system during any
inspection required in paragraph (i)(1) of this AD, before further
flight, replace damaged components as necessary 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.
(j) Optional Terminating Action
In lieu of the NLG fork and shimmy damper bracket inspections
required in paragraphs (h)(1) and (i)(1) of this AD, you may replace
the NLG fork P/N 100-410-7001 (type A) with a NLG fork P/N 100-410-
7013 (type B) following section 5. Instructions in Quest Aircraft
Field Service Instruction FSI-147, Revision 00 (not dated). 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 a NLG fork P/N 100-410-7013 (type B) is installed on an
airplane, do not install a NLG fork P/N 100-410-7001 (type A). If a
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 a
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
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
