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 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. 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.

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:

    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

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive:

Pacific Aerospace Limited: Docket No. FAA-2021-0603; Project 
Identifier 2019-CE-006-AD.

(a) Comments Due Date

    The FAA must receive comments on this airworthiness directive 
(AD) by September 13, 2021.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Pacific Aerospace Limited Model 750XL 
airplanes, serial numbers 100 through 205, 207 through 213, and 
8001, certificated in any category.

(d) Subject

    Joint Aircraft System Component (JASC) Code 2800, Aircraft Fuel 
System.

(e) Unsafe Condition

    This AD was prompted by mandatory continuing airworthiness 
information (MCAI) originated by an aviation authority of another 
country to identify and address 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.

(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.

(h) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, International Validation Branch, has the 
authority to approve AMOCs for this AD, if requested using the 
procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19, 
send your request to your principal inspector or local Flight 
Standards District Office, as appropriate. If sending information
