Comments Invited
Background
The Civil Aviation Authority (CAA),
which is the aviation authority for New
Zealand, has issued AD No. DCA/
750XL/34, 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:
The FAA invites you to send any
written relevant data, views, or
arguments about this proposal. Send
your comments to an address listed
under ADDRESSES. Include ‘‘Docket No.
DCA/750XL/34 is prompted by a report of
finding chafing damage in the port wing skin
caused by the fuel finger filters. The [CAA]
AD is issued to introduce inspection and
repair requirements with the issue of Pacific

Related Service Information Under 1
CFR Part 51
The FAA reviewed Pacific Aerospace
Limited Mandatory Service Bulletin
PACSB/XL/099, Issue 1, dated January
16, 2019. The service information
contains procedures for removing and
modifying the inspection panel
assembly, inspecting the wing internal
skin for chafing, repairing any chafing
damage and replacing the fuel filter as
necessary, and reinstalling the
inspection panel assembly. 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
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 is issuing
this NPRM after determining the unsafe
condition described previously is likely
to exist or develop on other products of
the same type design.
khammond on DSKJM1Z7X2PROD with PROPOSALS
Proposed AD Requirements in This
NPRM
This proposed AD would require
accomplishing the actions specified in
the service information already
described.
Costs of Compliance
The FAA estimates that this AD, if
adopted as proposed, would affect 23
airplanes of U.S. registry. The FAA also
estimates that it would take about 5
work-hours per airplane to do the
inspection and modification
requirements of this proposed AD, and
no parts would be necessary. Based on
these figures, the FAA estimates the cost
of the inspection and modification for
U.S. operators to be $9,725, or $425 per
product.
In addition, the FAA estimates that
any necessary follow-on actions for
repair or replacement requirements of
this proposed AD would take about 6
work-hours and require parts costing
VerDate Sep<11>2014
16:59 Jul 27, 2021
Jkt 253001
$150, for a cost of $660 per airplane.
The FAA has no way of determining the
number of airplanes that may need these
actions.
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
The FAA 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) Would not affect intrastate
aviation in Alaska, and
(3) Would not have a significant
economic impact, positive or negative,
on a substantial number of small entities
under the criteria of the Regulatory
Flexibility Act.

an unsafe condition for certain Pacific Aerospace Limited Model 750XL
airplanes. The MCAI states:
DCA/750XL/34 is prompted by a report of finding chafing damage
in the port wing skin caused by the fuel finger filters. The [CAA]
AD is issued to introduce inspection and repair requirements with
the issue of Pacific Aerospace Mandatory Service Bulletin (MSB)
[[Page 40385]]
PACSB/XL/099 issue 1, dated 16 January 2019.
The MCAI requires inspecting the wing internal skin for chafing and
taking any 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-2021-0603.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Pacific Aerospace Limited Mandatory Service
Bulletin PACSB/XL/099, Issue 1, dated January 16, 2019. The service
information contains procedures for removing and modifying the
inspection panel assembly, inspecting the wing internal skin for
chafing, repairing any chafing damage and replacing the fuel filter as
necessary, and reinstalling the inspection panel assembly. 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
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 is issuing this NPRM
after determining the unsafe condition described previously is likely
to exist or develop on other products of the same type design.
Proposed AD Requirements in This NPRM
This proposed AD would require accomplishing the actions specified
in the service information already described.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would
affect 23 airplanes of U.S. registry. The FAA also estimates that it
would take about 5 work-hours per airplane to do the inspection and
modification requirements of this proposed AD, and no parts would be
necessary. Based on these figures, the FAA estimates the cost of the
inspection and modification for U.S. operators to be $9,725, or $425
per product.
In addition, the FAA estimates that any necessary follow-on actions
for repair or replacement requirements of this proposed AD would take
about 6 work-hours and require parts costing $150, for a cost of $660
per airplane. The FAA has no way of determining the number of airplanes
that may need these actions.
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
The FAA 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) Would not affect intrastate aviation in Alaska, and
(3) Would 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

product. The MCAI describes the unsafe condition as chafing damage
in the port wing skin caused by the fuel system finger filters. The
FAA is issuing this AD to detect and correct chafing in the left
hand (LH) wing leading edge tank skin, which if not detected and
corrected, could result in a port wing fuel leak and lead to engine
failure or fire.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Required Actions
Within 165 hours time-in-service after the effective date of
this AD, modify the LH inspection panel assembly and inspect the LH
wing and fuel tank for chafing, and then, before further flight,
repair any chafing and install the panels in accordance with the
Accomplishment Instructions in Pacific Aerospace Limited Mandatory
Service Bulletin PACSB/XL/099, Issue 1, dated January 16, 2019.
