Abstract
The FAA is adopting a new airworthiness directive (AD) for certain Pacific Aerospace Limited Model 750XL airplanes. 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 chafing damage in the port wing skin caused by the fuel system finger filters. This AD requires inspecting the wing internal skin for chafing and taking any necessary corrective actions. The FAA is issuing this AD to address the unsafe condition on these products.

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 28, 2021 (86 FR 40384). 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/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:
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)
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 <a href="https://www.regulations.gov">https://www.regulations.gov</a> by searching for and locating Docket No. FAA-2021-
0603.
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 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 ADDRESSES.
Costs of Compliance
The FAA estimates that this AD affects 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 airplane.
In addition, the FAA estimates that that any necessary follow-on
actions for repair or replacement requirements of this AD will 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
[[Page 61064]]
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.

(a) Effective Date
This airworthiness directive (AD) is effective December 10,
2021.
(b) Affected ADs
None.
(c) Applicability

(e) Unsafe Condition
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 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.

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.
