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. FAA2021
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 FAAs 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 FAAs 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 Agencys 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.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.
The Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows:
