2020–16–12 Pacific Aerospace Limited:
Amendment 39–21196; Docket No.
FAA–2020–0717; Product Identifier
2019–CE–038–AD.
(a) Effective Date
This airworthiness directive (AD) becomes
effective September 8, 2020.
(b) Affected ADs
None.
(c) Applicability
This AD applies to Pacific Aerospace
Limited Model 750XL airplanes, serial
numbers 101 through 216, 220, 8001, and
8002, certificated in any category.
(d) Subject
Air Transport Association of America
(ATA) Code 76: Engine Controls.
(e) Reason
This AD was prompted by inadvertent fuel
shut-off to the engine during the operation of
the flaps, due to the fuel and flap control
levers being located too closely together. The
FAA is issuing this AD to adjust the position
of the fuel condition lever relative to the
control guide, which will prevent inadvertent
movement of the power lever into the cutoff
position if ground idle is selected and result
in engine failure and loss of airplane control.
(f) Actions and Compliance
Unless already done, within the next 30
days after September 8, 2020 (the effective
date of this AD), inspect the position of the
fuel condition lever by following the

SUPPLEMENTARY INFORMATION:
Discussion
The Civil Aviation Authority (CAA),
which is the aviation authority for New
Zealand, has issued AD DCA/750XL/
32B, dated February 7, 2019 (referred to
after this as ‘‘the MCAI’’), to correct an
unsafe condition for Pacific Aerospace
Limited Model 750XL airplanes. In its
notification of the MCAI, the CAA
states:
bolts may not have the required dual
retaining devices installed. Therefore,
the MCAI requires an inspection of the
MLG and the NLG. The NLG requires
the installation of a castellated nyloc
locking nut and a split pin. The MLG
requires the inspection and installation
of Palnuts on any attachment bolts that
do not have a Palnut installed. This
condition, if not detected and corrected,
could lead to failure of the NLG and
MLG.
You may examine the MCAI on the
internet at https://www.regulations.gov
by searching for and locating Docket No.
FAA–2020–0716.
Differences Between the MCAI and This
AD
The MCAI allows a licensed pilot
rated for this airplane to do daily visual
inspections of the nose landing gear
lower bolts and clamp for security for
up to 165 hours time-in-service until the
terminating corrective action is
performed. The FAA’s regulations do
not allow pilots to perform
maintenance, which includes
inspections, on U.S.-certificated
airplanes. Therefore, this AD does not
include the daily inspection
requirement and requires a shorter
compliance time for the terminating
corrective action to address the unsafe
condition in a timely manner.
Related Service Information Under 1
CFR Part 51
The FAA reviewed Pacific Aerospace
Mandatory Service Bulletin PACSB/XL/
105, Issue 4, dated December 19, 2018.
The service information contains
procedures for inspecting the NLG
lower bolts and clamp for security,
replacing the NLG locking nut and
Palnut with a castellated nyloc locking
nut and split pin, and inspecting the
MLG attachment bolts and installing
Palnuts as necessary. 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.
DCA/750XL/32B with effective date 7
February 2019 is prompted by several reports
of finding loose nose landing gear attachment
lock nuts and pal nuts. This [CAA] AD
revised to mandate Pacific Aerospace
Mandatory Service Bulletin (MSB) PACSB/
XL/105 issue 4, dated 19 December 2018,
which introduces alternate bolts for [part
number] P/N NAS6606D63 and
NAS6606D68.
Other Related Information
The FAA also reviewed Pacific
Aerospace Drawing BOL6603 THRU
6620, dated December 19, 2018. This
drawing contains additional information
related to fabrication of the required
part number bolts for the NLG.
The MCAI is part of an extensive
evaluation and investigation by the New
Zealand CAA on the Pacific Aerospace
Model 750XL. The unsafe condition
results from a production quality issue
where the MLG and NLG attachment

bilateral agreement with this State of
Design Authority, they have notified us
of the unsafe condition described in the
MCAI and service information
referenced above. The FAA is issuing
this AD because it evaluated all
information provided by the State of
Design Authority and determined the
unsafe condition exists and is likely to
exist or develop on other products of the
same type design.
FAA’s Determination of the Effective
Date
An unsafe condition exists that
requires the immediate adoption of this
AD. The risk assessment received by the
FAA, and reconfirmed in July of 2020,
indicates that urgent action is required.
The FAA has found that the risk to the
flying public justifies waiving notice
and comment prior to adoption of this
rule because without the required dual
retaining devices, the NLG and the MLG
could fail and result in reduced control
on the ground and lead to a runway
excursion. Because this AD does not
include the daily inspections, the FAA
finds that compliance is necessary
within 20 hours time-in-service or 30
days, whichever occurs first, to address
the unsafe condition. Therefore, the
FAA finds good cause that notice and
opportunity for prior public comment
are impracticable. In addition, for the
reasons stated above, the FAA finds that
good cause exists for making this
amendment effective in less than 30
days.
Comments Invited
This AD is a final rule that involves
requirements affecting flight safety and
was not preceded by notice and an
opportunity for public comment.
However, the FAA invites you to send
any written data, views, or arguments
about this final rule. Send your
comments to an address listed under the
ADDRESSES section. Include the Docket
Number FAA–2020–0716 and Product
Identifier 2019–CE–009–AD at the
beginning of your comments. 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 https://
www.regulations.gov, including any
personal information you provide. The
FAA will also post a report
summarizing each substantive verbal
contact we receive about this final rule.

Federal Register / Vol. 85, No. 159 / Monday, August 17, 2020 / Rules and Regulations
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 Mike Kiesov,
Aerospace Engineer, FAA, Small
Airplane Standards Branch, 901 Locust,
Room 301, Kansas City, Missouri 64106.
Any commentary that the FAA receives
which is not specifically designated as
CBI will be placed in the public docket
for this rulemaking.
Costs of Compliance
The FAA estimates that this AD will
affect 22 products of U.S. registry. The
FAA also estimates that it would take
about 5 work-hours per product to
comply with the basic requirements of
this AD. The average labor rate is $85
per work-hour. Required parts would
cost about $20 per product.
Based on these figures, the FAA
estimates the cost of the AD on U.S.
operators to be $9,790, or $445 per
product.
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 notice and
comment, RFA analysis is not required.
Regulatory Findings
The FAA determined that 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
(2) Will not affect intrastate aviation
in Alaska.

Adoption of 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
1. The authority citation for part 39
continues to read as follows:
■
Authority for This Rulemaking
Authority: 49 U.S.C. 106(g), 40113, 44701.
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.

NPRM published in the Federal
Register on February 18, 2020 (85 FR
8771). The NPRM was prompted by two
incidents of erroneous low oil pressure
caution cockpit indications and
unintended actuation of the MGB auto
bypass valve caused by unintended
popping of the M XMSN OIL WARN
circuit breaker during flight. The root
cause of this circuit breaker popping is
unknown. When this circuit breaker
trips, the following cautions will
display ‘‘MGB PUMP 1 FAIL, MGB
PUMP 2 FAIL, MGB OIL HOT, MGB
MAN COOL, MGB OIL PRES.’’ With the
MGB auto bypass valve actuated, the
MGB BYPASS caution will not
annunciate. For the given conditions,
the appropriate action for the crew is
‘‘land as soon as possible’’ in
accordance with the RFM Emergency
Procedures. The erroneous indications
conflicting with correct gauge readings
may overwhelm the flight crew,
resulting in a forced landing of the
helicopter.
To address this unsafe condition,
Sikorsky developed MOD kits based on
helicopter S/N to introduce a separate
circuit breaker for the MGB last jet
pressure switch. These MOD kits
specify reworking the overhead panel to
install new clips and brackets, circuit
breaker wiring harnesses, wiring MODs,
the auxiliary circuit breaker panel, and
the M XMSN PRESS SWITCH circuit
breaker. Accordingly, the NPRM
proposed to require installing MOD kits
and inserting an RFM Supplement into
the existing RFM for your helicopter.
The FAA is issuing this AD to address
the unsafe condition on these products.
Comments
The FAA gave the public the
opportunity to participate in developing
this final rule. The FAA received
comments from one commenter. The
following presents the comments
received on the NPRM and the FAA’s
response to the comments.
Request
The commenter expressed concern
about the compliance time of 400 hours
time-in-service (TIS), described it as a
substantial amount of time, and
suggested operators fix the problem
immediately. The commenter did not
provide a technical rationale for the
FAA to review.
The FAA disagrees that a shorter
compliance time is required to correct
the unsafe condition. In determining
that a compliance time of 400 hours TIS
mitigates the risk to an acceptable level,
the FAA considered factors including
Sikorsky service information, the scope
of the required actions in this AD, and

SUPPLEMENTARY INFORMATION:
Discussion
The Civil Aviation Authority (CAA), which is the aviation authority
for New Zealand, has issued AD DCA/750XL/32B, dated February 7, 2019
(referred to after this as ``the MCAI''), to correct an unsafe
condition for Pacific Aerospace Limited Model 750XL airplanes. In its
notification of the MCAI, the CAA states:
DCA/750XL/32B with effective date 7 February 2019 is prompted by
several reports of finding loose nose landing gear attachment lock
nuts and pal nuts. This [CAA] AD revised to mandate Pacific
Aerospace Mandatory Service Bulletin (MSB) PACSB/XL/105 issue 4,
dated 19 December 2018, which introduces alternate bolts for [part
number] P/N NAS6606D63 and NAS6606D68.
The MCAI is part of an extensive evaluation and investigation by
the New Zealand CAA on the Pacific Aerospace Model 750XL. The unsafe
condition results from a production quality issue where the MLG and NLG
attachment bolts may not have the required dual retaining devices
installed. Therefore, the MCAI requires an inspection of the MLG and
the NLG. The NLG requires the installation of a castellated nyloc
locking nut and a split pin. The MLG requires the inspection and
installation of Palnuts on any attachment bolts that do not have a
Palnut installed. This condition, if not detected and corrected, could
lead to failure of the NLG and MLG.
You may examine the MCAI on the internet at https://www.regulations.gov by searching for and locating Docket No. FAA-2020-
0716.
Differences Between the MCAI and This AD
The MCAI allows a licensed pilot rated for this airplane to do
daily visual inspections of the nose landing gear lower bolts and clamp
for security for up to 165 hours time-in-service until the terminating
corrective action is performed. The FAA's regulations do not allow
pilots to perform maintenance, which includes inspections, on U.S.-
certificated airplanes. Therefore, this AD does not include the daily
inspection requirement and requires a shorter compliance time for the
terminating corrective action to address the unsafe condition in a
timely manner.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Pacific Aerospace Mandatory Service Bulletin
PACSB/XL/105, Issue 4, dated December 19, 2018. The service information
contains procedures for inspecting the NLG lower bolts and clamp for
security, replacing the NLG locking nut and Palnut with a castellated
nyloc locking nut and split pin, and inspecting the MLG attachment
bolts and installing Palnuts as necessary. 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.
Other Related Information
The FAA also reviewed Pacific Aerospace Drawing BOL6603 THRU 6620,
dated December 19, 2018. This drawing contains additional information
related to fabrication of the required part number bolts for the NLG.
FAA's Determination and Requirements of the AD
This product has been approved by the aviation authority of another
country, and is approved for operation in the United States. Pursuant
to our bilateral agreement with this State of Design Authority, they
have notified us of the unsafe condition described in the MCAI and
service information referenced above. The FAA is issuing this AD
because it evaluated all information provided by the State of Design
Authority and determined the unsafe condition exists and is likely to
exist or develop on other products of the same type design.
FAA's Determination of the Effective Date
An unsafe condition exists that requires the immediate adoption of
this AD. The risk assessment received by the FAA, and reconfirmed in
July of 2020, indicates that urgent action is required. The FAA has
found that the risk to the flying public justifies waiving notice and
comment prior to adoption of this rule because without the required
dual retaining devices, the NLG and the MLG could fail and result in
reduced control on the ground and lead to a runway excursion. Because
this AD does not include the daily inspections, the FAA finds that
compliance is necessary within 20 hours time-in-service or 30 days,
whichever occurs first, to address the unsafe condition. Therefore, the
FAA finds good cause that notice and opportunity for prior public
comment are impracticable. In addition, for the reasons stated above,
the FAA finds that good cause exists for making this amendment
effective in less than 30 days.
Comments Invited
This AD is a final rule that involves requirements affecting flight
safety and was not preceded by notice and an opportunity for public
comment. However, the FAA invites you to send any written data, views,
or arguments about this final rule. Send your comments to an address
listed under the ADDRESSES section. Include the Docket Number FAA-2020-
0716 and Product Identifier 2019-CE-009-AD at the beginning of your
comments. 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
https://www.regulations.gov, including any personal information you
provide. The FAA will also post a report summarizing each substantive
verbal contact we receive about this final rule.
[[Page 49951]]
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 Mike
Kiesov, Aerospace Engineer, FAA, Small Airplane Standards Branch, 901
Locust, Room 301, Kansas City, Missouri 64106. Any commentary that the
FAA receives which is not specifically designated as CBI will be placed
in the public docket for this rulemaking.
Costs of Compliance
The FAA estimates that this AD will affect 22 products of U.S.
registry. The FAA also estimates that it would take about 5 work-hours
per product to comply with the basic requirements of this AD. The
average labor rate is $85 per work-hour. Required parts would cost
about $20 per product.
Based on these figures, the FAA estimates the cost of the AD on
U.S. operators to be $9,790, or $445 per product.
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 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 notice and comment,
RFA analysis is not required.
Regulatory Findings
The FAA determined that 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
(2) Will not affect intrastate aviation in Alaska.

Gear.
(e) Reason
This AD was prompted by mandatory continuing airworthiness
information (MCAI) originated by an aviation authority of another
country to identify and correct an unsafe condition on an aviation
product. The MCAI identifies the unsafe condition as nose landing
gear (NLG) and main landing gear (MLG) attachment bolts without dual
retaining devices. The FAA is issuing this AD to prevent the NLG and
MLG attachment bolts from detaching, which if not corrected could
lead to failure of the landing gear.

Unless already done, comply with this AD within 20 hours time-
in-service after September 8, 2020 (the effective date of this AD)
or within 30 days after September 8, 2020 (the effective date of
this AD), whichever occurs first.
(1) Replace each NLG upper and lower attachment lock nut and
Palnut with castellated nyloc locking nuts and spring/split pins by
following steps 6 and 8 in Part B-Accomplishment Instructions (Nose
Landing Gear) of Pacific Aerospace Mandatory Service Bulletin PACSB/
XL/105, Issue 4, dated December 19, 2018 (PACSB/XL/105, Issue 4).
(2) For airplanes with a S/N up to and including 185, except S/N
177 and except airplanes with modification PAC/XL/0448: inspect the
upper and lower attachment bolts on both MLGs for the installation
of Palnuts (four on each MLG) as depicted in figure 6 in Part C--
Accomplishment Instructions (Main Landing Gear) of PACSB/XL/105,
Issue 4.
(i) If Palnuts are installed in all eight locations (four on
each MLG), no further action is required.
(ii) If a Palnut is not installed on an MLG attachment bolt,
before further flight, check the torque of the attachment bolt and
install a Palnut by following steps 5 through 7 in Part C-
Accomplishment Instructions (Main Landing Gear) of PACSB/XL/105,
Issue 4.
