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 describes the unsafe condition as chafing damage in the port wing skin caused by the fuel system finger filters. This proposed AD would require inspecting the wing internal skin for chafing and taking any necessary corrective actions. The FAA is proposing this AD to address the unsafe condition on these products.

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. FAA-2021-0603; Project Identifier
2019-CE-006-AD'' at the beginning of your comments. The most helpful
comments reference a specific portion of the proposal, explain the
reason for any recommended change, and include supporting data. The FAA
will consider all comments received by the closing date and may amend
this proposal because of those comments.
Except for Confidential Business Information (CBI) as described in
the following paragraph, and other information as described in 14 CFR
11.35, the FAA will post all comments received, without change, to
<a href="https://www.regulations.gov">https://www.regulations.gov</a>, including any personal information you
provide. The agency will also post a report summarizing each
substantive verbal contact received about this NPRM.
Confidential Business Information
CBI is commercial or financial information that is both customarily
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, International Validation Branch, FAA, 901 Locust, Room 301,
Kansas City, MO 64106. Any commentary that the FAA receives which is
not specifically designated as CBI will be placed in the public docket
for this rulemaking.
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 <a href="https://www.regulations.gov">https://www.regulations.gov</a> 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
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-2021-0603; 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.
