SUPPLEMENTARY INFORMATION:
jspears on DSK121TN23PROD with RULES1
Background
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would
apply to certain serial-numbered Pacific
Aerospace Limited Model 750XL
airplanes. The NPRM published in the
Federal Register on July 22, 2021 (86 FR
38615). The NPRM was prompted by
MCAI originated by the Civil Aviation
Authority (CAA), which is the aviation
authority for New Zealand. The CAA of
New Zealand has issued AD No. DCA/
750XL/36, effective date February 7,
2019 (referred to after this as ‘‘the
MCAI’’), to correct an unsafe condition
for certain Pacific Aerospace Limited
Model 750XL airplanes. The MCAI
states:
DCA/750XL/36 is prompted by a review of
the installation of the wing leading edge fuel
pickup assemblies. It was found that the fuel
pickup assemblies could have been installed
in a pre-stressed condition, which could
result in cracks in the wing spar web, or
cracks in the fuel pickup pipe. The [CAA] AD
is issued to introduce the instructions in

Jkt 256001
Pacific Aerospace Mandatory Service
Bulletin (MSB) PACSB/XL/109 issue 1, dated
16 January 2019.
The MCAI requires inspecting the
installation of the fuel pickup assembly
and the wing spar web on both wings
and, if any defects are found, taking all
necessary corrective actions.
You may examine the MCAI in the
AD docket at https://
www.regulations.gov by searching for
and locating Docket No. FAA–2021–
0576.
Discussion of Final Airworthiness
Directive
Comments
The FAA received no comments on
the NPRM or on the determination of
the costs.
Conclusion
This product has been approved by
the aviation authority of another
country and is approved for operation in
the United States. Pursuant to the FAA’s
bilateral agreement with this State of
Design Authority, it has notified the
FAA of the unsafe condition described
in the MCAI and service information
referenced above. The FAA reviewed
the relevant data and determined that
air safety requires adopting this AD as
proposed. Accordingly, the FAA is
issuing this AD to address the unsafe
condition on these products. This AD is
adopted as proposed in the NPRM.
Related Service Information Under 1
CFR Part 51
The FAA reviewed Pacific Aerospace
Mandatory Service Bulletin PACSB/XL/
109, Issue 1, dated January 16, 2019.
The service information contains
procedures for inspecting the wing
leading edge tank fuel pickup assembly
to determine if the assembly is under
stress and for accomplishing additional
inspections and corrective actions if
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
ADDRESSES.
Costs of Compliance
The FAA estimates that this AD
affects 23 airplanes of U.S. registry. The
FAA also estimates it will take about 1
work-hour per airplane to comply with
the inspection required by this AD. The
average labor rate is $85 per work-hour.
Based on these figures, the FAA
estimates the inspection cost of this AD
on U.S. operators to be $1,955 or $85
per airplane.
In addition, the FAA estimates that
any necessary follow-on actions will
PO 00000
Frm 00031
Fmt 4700
Sfmt 4700
57559
take 4 work-hours and require parts
costing $500, for a cost of $840 per
airplane. The FAA has no way of
determining the number of airplanes
that may need these actions.
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,
(2) Will not affect intrastate aviation
in Alaska, and
(3) 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.

SUPPLEMENTARY INFORMATION:
Background
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 by adding an AD that would apply to certain serial-numbered
Pacific Aerospace Limited Model 750XL airplanes. The NPRM published in
the Federal Register on July 22, 2021 (86 FR 38615). The NPRM was
prompted by MCAI originated by the Civil Aviation Authority (CAA),
which is the aviation authority for New Zealand. The CAA of New Zealand
has issued AD No. DCA/750XL/36, effective date February 7, 2019
(referred to after this as ``the MCAI''), to correct an unsafe
condition for certain Pacific Aerospace Limited Model 750XL airplanes.
The MCAI states:
DCA/750XL/36 is prompted by a review of the installation of the
wing leading edge fuel pickup assemblies. It was found that the fuel
pickup assemblies could have been installed in a pre-stressed
condition, which could result in cracks in the wing spar web, or
cracks in the fuel pickup pipe. The [CAA] AD is issued to introduce
the instructions in Pacific Aerospace Mandatory Service Bulletin
(MSB) PACSB/XL/109 issue 1, dated 16 January 2019.
The MCAI requires inspecting the installation of the fuel pickup
assembly and the wing spar web on both wings and, if any defects are
found, taking all necessary corrective actions.

Discussion of Final Airworthiness Directive
Comments
The FAA received no comments on the NPRM or on the determination of
the costs.
Conclusion
This product has been approved by the aviation authority of another
country and is approved for operation in the United States. Pursuant to
the FAA's bilateral agreement with this State of Design Authority, it
has notified the FAA of the unsafe condition described in the MCAI and
service information referenced above. The FAA reviewed the relevant
data and determined that air safety requires adopting this AD as
proposed. Accordingly, the FAA is issuing this AD to address the unsafe
condition on these products. This AD is adopted as proposed in the
NPRM.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Pacific Aerospace Mandatory Service Bulletin
PACSB/XL/109, Issue 1, dated January 16, 2019. The service information
contains procedures for inspecting the wing leading edge tank fuel
pickup assembly to determine if the assembly is under stress and for
accomplishing additional inspections and corrective actions if
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 ADDRESSES.
Costs of Compliance
The FAA estimates that this AD affects 23 airplanes of U.S.
registry. The FAA also estimates it will take about 1 work-hour per
airplane to comply with the inspection required by this AD. The average
labor rate is $85 per work-hour.
Based on these figures, the FAA estimates the inspection cost of
this AD on U.S. operators to be $1,955 or $85 per airplane.
In addition, the FAA estimates that any necessary follow-on actions
will take 4 work-hours and require parts costing $500, for a cost of
$840 per airplane. The FAA has no way of determining the number of
airplanes that may need these actions.
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,
(2) Will not affect intrastate aviation in Alaska, and
(3) 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.
