Abstract
The FAA proposes to adopt a new airworthiness directive (AD) for certain Pacific Aerospace Limited Model 750XL airplanes. This proposed 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 insufficient clearance between the engine mount, the Beta control rod, and the inter-turbine temperature (ITT) sensing probe that could lead to chafing damage. This proposed AD would require inspecting the engine mount, the temperature probe, and the reversing cable for damage, and taking any necessary corrective actions. The FAA is proposing this AD to address the unsafe condition on these products.

and actually treated as private by its owner. Under the Freedom of
Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public
disclosure. If your comments responsive to this NPRM contain commercial
or financial information that is customarily treated as private, that
you actually treat as private, and that is relevant or responsive to
this NPRM, it is important that you clearly designate the submitted
comments as CBI. Please mark each page of your submission containing
CBI as ``PROPIN.'' The FAA will treat such marked submissions as
confidential under the FOIA, and they will not be placed in the public
docket of this NPRM. Submissions containing CBI should be sent to Mike
Kiesov, Aviation Safety Engineer, General Aviation & Rotorcraft
Section, FAA, International Validation Branch, 901 Locust, Room 301,

Background
The Civil Aviation Authority (CAA), which is the aviation authority
for New Zealand, has issued AD DCA/750XL/35, 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/35 is prompted by a review of the engine installation
procedures, which identified that the clearance between the engine
mount, the Beta control rod and the inter-turbine temperature (ITT)
sensing probe could be insufficient and result in chafing damage.
The [CAA] AD is issued to introduce the instructions in Pacific
Aerospace Mandatory Service Bulletin (MSB) PACSB/XL/102 issue 2,
dated 5 November 2018.
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-
0604.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Pacific Aerospace Limited Mandatory Service
Bulletin PACSB/XL/102, Issue 2, dated November 5, 2018. This service
information specifies procedures for removing support clamps if
installed by following the prior version of the service bulletin;
inspecting the engine mount, the temperature probe, and the reversing
cable for signs of chafing or damage; installing anti-chafing blade
tape onto the engine mount tube; and obtaining further guidance for
corrective actions. 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.
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 in the
service information described above, except as discussed under
Differences Between
[[Page 40383]]
this Proposed AD and the Service Information.
Differences Between This Proposed AD and the Service Information
Where the service information states to contact Pacific Aerospace
Limited if chafing or any damage is present on an engine mount,
temperature probe, or reversing cable, this proposed AD would require
contacting the CAA of New Zealand.
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 2 work-hours per
airplane to comply with the inspection and install anti-chafing blade
tape. The average labor rate is $85 per work-hour and required parts
would cost about $10 per product for an estimated cost of $4,140 on
U.S. operators, or $180 per airplane.
The damage found during the proposed inspection may vary from
airplane to airplane. The FAA has no way of knowing how much damage
each airplane may have or the cost to repair the damage for each
airplane.
Contacting the CAA of New Zealand, if required, would take about 1
work-hour for an estimated cost of $85 per airplane.
The FAA has included all known costs in this 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.
Paperwork Reduction Act
A federal agency may not conduct or sponsor, and a person is not
required to respond to, nor shall a person be subject to a penalty for
failure to comply with a collection of information subject to the
requirements of the Paperwork Reduction Act unless that collection of
information displays a current valid OMB Control Number. The OMB
Control Number for this information collection is 2120-0056. Public
reporting for this collection of information is estimated to take
approximately 1 hour per response, including the time for reviewing
instructions, searching existing data sources, gathering and
maintaining the data needed, and completing and reviewing the
collection of information. All responses to this collection of
information are mandatory. Send comments regarding this burden estimate
or any other aspect of this collection of information, including
suggestions for reducing this burden, to: Information Collection
Clearance Officer, Federal Aviation Administration, 10101 Hillwood
Parkway, Fort Worth, TX 76177-1524.
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
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.
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-2021-0604; Project
Identifier 2019-CE-007-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 101 through 215, 220, 8001, and 8002,
certificated in any category.
(d) Subject
Joint Aircraft System Component (JASC) Code 7100, Power Plant
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 correct an unsafe condition on an aviation
product. The MCAI identifies the unsafe condition as insufficient
clearance between the engine mount, the Beta control rod, and the
inter-turbine temperature (ITT) sensing probe that could lead to
chafing damage. The FAA is issuing this AD to prevent damage to the
engine mount, temperature probe, and the reversing cable. The unsafe
condition, if not addressed, could result in chafing damage to the
ITT system and binding of the Beta control rod.
(f) Actions and Compliance
(1) Unless already done, within 165 hours time-in-service after
the effective date of this AD, inspect the engine mount, the
temperature probe, and the reversing cable for damage, and, before
further flight, take all necessary corrective actions and install
anti-chafing blade tape onto the engine mount tube by following the
Accomplishment Instructions in Pacific Aerospace Limited Mandatory
Service Bulletin PACSB/XL/102, Issue 2, dated November 5, 2018.
(2) Where the service information states to contact Pacific
Aerospace Limited if chafing or any damage is present on an engine
mount, temperature probe, or reversing cable, this AD requires
instead that you contact the Civil Aviation Authority (CAA) of New
Zealand at the contact information in paragraph (h)(3) of this AD.
(g) 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
directly to the manager of the certification office, send it to the
attention of the person identified in Related Information
