Airworthiness Directives; Pacific Aerospace Limited Model FU-24
Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: We propose to adopt a new airworthiness directive (AD) for the
products listed above. This proposed AD results from 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:

    To prevent the possible in-flight failure of the vertical fin,
leading to loss of control of the aircraft * * *

    The proposed AD would require actions that are intended to address
the unsafe condition described in the MCAI.

DATES: We must receive comments on this proposed AD by June 12, 2008.

Discussion

    The Civil Aviation Authority of New Zealand, which is the aviation
authority for New Zealand, has issued AD DCA/FU24/176C, dated September
27, 2007 (referred to after this as ``the MCAI''), to correct an unsafe
condition for the specified products. The MCAI states:

    To prevent the possible in-flight failure of the vertical fin,
leading to loss of control of the aircraft * * *

    The MCAI requires inspections of the vertical fin for cracking,
corrosion, scratches, dents, creases or buckling and the repair of any
damaged area. You may obtain further information by examining the MCAI
in the AD docket.

Relevant Service Information

    The Civil Aviation Authority of New Zealand, which is the aviation
authority for New Zealand, makes reference to Pacific Aerospace Limited
Chapter 05, page 25 of the FU-24-950 Series Maintenance Manual, issued
December 1978. The actions described in this service information are
intended to correct the unsafe condition identified in the MCAI.

FAA's Determination and Requirements of the Proposed AD

    This product has been approved by the aviation authority of another
country, and is approved for operation in the United States. Pursuant
to our bilateral agreement with this State of Design Authority, they
have notified us of the unsafe condition described in the MCAI and
service information referenced above. We are proposing this AD because
we evaluated all information and determined the unsafe condition exists
and is likely to exist or develop on other products of the same type
design.

Differences Between This Proposed AD and the MCAI or Service
Information

    We have reviewed the MCAI and related service information and, in
general, agree with their substance. But we might have found it
necessary to use different words from those in the MCAI to ensure the
AD is clear for U.S. operators and is enforceable. In making these
changes, we do not intend to differ substantively from the information
provided in the MCAI and related service information.
    We might also have proposed different actions in this AD from those
in the MCAI in order to follow FAA policies. Any such differences are
highlighted in a NOTE within the proposed AD.

Costs of Compliance

    We estimate that this proposed AD will affect 2 products of U.S.
registry. We also estimate that it would take about 1 work-hour per
product to comply with the basic requirements of this proposed AD. The
average labor rate is $80 per work-hour.
    Based on these figures, we estimate the cost of the proposed AD on
U.S. operators to be $160, or $80 per product.
    In addition, we estimate that any necessary follow-on actions would
take about 24 work-hours and require parts costing $1,000, for a cost
of $2,920 per product. We have no way of determining the number of
products 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.
    We are 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

    We 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. Is not a ``significant rule'' under the DOT Regulatory Policies
and Procedures (44 FR 11034, February 26, 1979); 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.
    We prepared a regulatory evaluation of the estimated costs to
comply with this proposed AD and placed it in the AD docket.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, 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

    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]

    2. The FAA amends Sec.  39.13 by adding the following new AD:

Pacific Aerospace Limited: Docket No. FAA-2008-0543; Directorate
Identifier 2007-CE-092-AD.

Comments Due Date

    (a) We must receive comments by June 12, 2008.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to FU-24 airplanes, all serial numbers,
certificated in any category.

Subject

    (d) Air Transport Association of America (ATA) Code 53:
Fuselage.

Reason

    (e) The mandatory continuing airworthiness information (MCAI)
states:
    To prevent the possible in-flight failure of the vertical fin,
leading to loss of control of the aircraft * * *
    The MCAI requires inspections of the vertical fin for cracking,
corrosion, scratches, dents, creases or buckling, and the repair of
any damaged area.

Actions and Compliance

    (f) Unless already done, after the effective date of this AD, do
the following actions following Chapter 05, page 25 of the FU-24-950
Series Maintenance Manual:
    (1) Before the first flight of the day, visually inspect the
vertical stabilizer leading edge skin and fin for any cracking,
corrosion, scratches, dents, creases or buckling, and repair as
necessary. All non-transparent protective coatings and their
adhesive must be removed for this inspection.
    (2) Within 100 hours time-in-service (TIS) after the effective
date of this AD and repetitively thereafter at intervals not to
exceed 100 hours TIS, perform a detailed inspection of the vertical
stabilizer leading edge skin, leading edge, fin skin, and the fin
forward attachment point for any cracking, corrosion, scratches,
dents, creases, or buckling to include:
    (i) Inspection of the entire leading edge down to the forward
attach fitting; and removal of dorsal fin extensions if installed in
order to inspect the obscured areas of the fin.
    (ii) Inspection of the fin skin for corrosion and cracks, paying
particular attention to the center rib rivet holes and the skin
joint at the fin base.
    (iii) Inspection of the fin forward attachment point for
corrosion, removal of the fin tip, and inspection of the top rib for
cracks at the skin stiffener cut outs.
    (3) If any damage is found during any inspection required in
paragraph (f)(1) or (f)(2) of this AD, before further flight, obtain
an FAA-approved repair scheme from the manufacturer and incorporate
that repair.
    (4) The following transparent polyurethane protective tapes have
been assessed as suitable for use to re-protect the leading edge and
may remain in situ for subsequent inspections, provided they are
sound and in a condition to permit visual inspection of the skin
beneath them:

------------------------------------------------------------------------
               Manufacturer                            Product
------------------------------------------------------------------------
(i) 3M....................................   8591, or 8671, 8672 and
                                             8681HS (aeronautical
                                             grade).
(ii) Scapa................................  Aeroshield P2604
                                             (transparent).
------------------------------------------------------------------------

    Note 1: You may apply for an alternative method of compliance
(AMOC) for an alternative to the transparent polyurethane protective
tapes listed above.

FAA AD Differences

    Note 2: This AD differs from the MCAI and/or service information
as follows:
    (1) The inspections required in this AD must be performed by a
person authorized under 14 CFR part 43 to perform inspections, as
opposed to the MCAI, which allows the holder of a pilot license to
perform the inspections.
    (2) The 50-hour inspection required in the MCAI goes away
because the ``before each flight'' inspection captures the intent.

Other FAA AD Provisions

    (g) The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager,
Standards Office, FAA, has the authority to approve AMOCs for this
AD, if requested using the procedures found in 14 CFR 39.19. Send
information to ATTN: Karl Schletzbaum, Aerospace Engineer, FAA,
Small Airplane Directorate, 901 Locust, Room 301, Kansas City,
Missouri 64106; telephone:<PHONE_NUMBER>; fax:<PHONE_NUMBER>.
Before using any approved AMOC on any airplane to which the AMOC
applies, notify your appropriate principal inspector (PI) in the FAA
Flight Standards District Office (FSDO), or lacking a PI, your local
FSDO.
    (2) Airworthy Product: For any requirement in this AD to obtain
corrective actions from a manufacturer or other source, use these
actions if they are FAA-approved. Corrective actions are considered
FAA-approved if they are approved by the State of Design Authority
(or their delegated agent). You are required to assure the product
is airworthy before it is returned to service.
    (3) Reporting Requirements: For any reporting requirement in
this AD, under the provisions of the Paperwork Reduction Act (44
U.S.C. 3501 et seq.), the Office of Management and Budget (OMB) has
approved the information collection requirements and has assigned
OMB Control Number 2120-0056.

33 CFR Part 165

[Docket Number USCG-2023-0199]
RIN 1625-AA00

Safety Zone: Tall Ships America; Galveston, TX

AGENCY: Coast Guard, Department of Homeland Security (DHS).

ACTION: Temporary final rule.

-----------------------------------------------------------------------

SUMMARY: The Coast Guard is establishing a temporary moving safety zone
on the waters of the Gulf of Mexico off the coast of Galveston, around
a Tall Ships America Parade of Sail in Galveston, Texas. Once the
vessels are moored at the Galveston Historic Seaport, a temporary fixed
safety zone will be established. The safety zones are necessary to
protect the public and wooden sailing vessels and their crews from the
hazards associated with transiting the area. Persons and vessels are
prohibited from entering, transiting through, anchoring in, or
remaining within the moving and fixed safety zones unless authorized by
the Captain of the Port Houston-Galveston or a designated
representative.

DATES:  This rule will be effective from 11 a.m. April 13, 2023,
through 6 p.m. on April 16, 2023.

ADDRESSES:  To view documents mentioned in this preamble as being

SUPPLEMENTARY INFORMATION:

I. Table of Abbreviations

CFR Code of Federal Regulations
DHS Department of Homeland Security
FR Federal Register
NPRM Notice of proposed rulemaking
Sec.  Section
U.S.C. United States Code

II. Background Information and Regulatory History

    The Coast Guard is issuing this temporary rule without prior notice
and opportunity to comment pursuant to authority under section 4(a) of
the Administrative Procedure Act (APA) (5 U.S.C. 553(b)). This
provision authorizes an agency to issue a rule without prior notice and
opportunity to comment when the agency for good cause finds that those
procedures are ``impracticable, unnecessary, or contrary to the public
interest.'' Under 5 U.S.C. 553(b)(B), the Coast Guard finds that good
cause exists for not publishing a notice of proposed rulemaking (NPRM)
with respect to this rule because it is impracticable. The Coast Guard
received all amplifying information for this Tall Ships event regarding
the need for a safety zone on March 6, 2023. Insufficient time remains
to publish a NPRM and to receive public comments, as the event will
occur on April 13, 2023, before the rulemaking process would be
completed. Because of the potential safety hazards associated with the
Parade of Sail, the regulation is necessary to provide for the safety
of the Tall Ships and their crew, spectators, and other vessels
navigating the surrounding waterways. For those reasons, it would be
impracticable to publish an NPRM.
    Under 5 U.S.C. 553(d)(3), the Coast Guard finds that good cause
exists for making this rule effective less than 30 days after
publication in the Federal Register. For the reasons discussed above,
the Coast Guard finds that good cause exists.

III. Legal Authority and Need for Rule

    The Coast Guard is issuing this rule under authority in 46 U.S.C.
70034. The Captain of the Port Houston-Galveston has determined that
potential hazards associated with the Parade of Sail, will be a safety
concern for the Tall Ships and their crews, spectators, and vessels.
This rule is needed to ensure the safety of life for vessels and
persons within the navigable waters of the safety zone during the
Parade of Sail in Galveston, Texas.

IV. Discussion of the Rule

    This rule establishes a temporary moving safety zone extending 100
yards from the wooden sailing vessels participating in the Tall Ships
America Parade from 11 a.m. through 4 p.m. on April 13, 2023, starting
in approximate position 29[deg]19.181' N 094[deg]43.165' W to the turn
around point at 29[deg]16.6' N 094[deg]48.5' W, then proceeding through
the Houston Ship Channel and Galveston Ship Channel to their assigned
docking stations in the vicinity of the Galveston Historic Seaport.
Once vessels are moored at the Galveston Historic Seaport in Galveston,
TX, the

temporary fixed safety zone will be in effect from 2 p.m. on April 13,
2023, through 6 p.m. on April 16, 2023, and extend 25 yards from the
vessels. The temporary safety zones will cover all navigable waters
within a specified area of the Gulf of Mexico and the Port of
Galveston. The duration of the zones are intended to ensure the safety
of the public and these navigable waters during the Tall Ships America
Parade of Sail and while the vessels are moored. No vessel or person
will be permitted to enter, transit through, anchor in, or remain
within the safety zones without obtaining permission from the Captain
of the Port Houston-Galveston or a designated representative.
    Persons and vessels may request authorization to enter, transit
through, anchor in, or remain within the regulated area by contacting
the Captain of the Port Houston-Galveston by telephone at (713) 398-
5823, or a designated representative via VHF radio on channel 16. If
authorization to enter, transit through, anchor in, or remain within
the regulated area is granted by the Captain of the Port Houston-
Galveston or a designated representative, all persons and vessels
receiving such authorization must comply with the instructions of the
Captain of the Port Houston-Galveston or a designated representative.
The Coast Guard will provide notice of the safety zones by Local Notice
to Mariners, Broadcast Notice to Mariners, and/or on-scene designated
representatives.

V. Regulatory Analyses

    We developed this rule after considering numerous statutes and
Executive orders related to rulemaking. Below we summarize our analyses
based on a number of these statutes and Executive orders, and we
discuss First Amendment rights of protestors.

A. Regulatory Planning and Review

    Executive Orders 12866 and 13563 direct agencies to assess the
costs and benefits of available regulatory alternatives and, if
regulation is necessary, to select regulatory approaches that maximize
net benefits. This rule has not been designated a ``significant
regulatory action,'' under Executive Order 12866. Accordingly, this
rule has not been reviewed by the Office of Management and Budget
(OMB).
    This regulatory action determination is based on: (1) The safety
zones will be enforced for a limited period of time over the course of
four days during the Tall Ships America Parade of Sail and touring
times at the pier; (2) although persons and vessels are prohibited to
enter, transit through, anchor in, or remain within the regulated area
without authorization from the Captain of the Port Houston-Galveston or
a designated representative, they may operate in the surrounding area
during the enforcement period; and (3) the Coast Guard will provide
advance notification of the safety zones to the local maritime
community by Local Notice to Mariners and/or Broadcast Notice to
Mariners.

B. Impact on Small Entities

    The Regulatory Flexibility Act of 1980, 5 U.S.C. 601-612, as
amended, requires Federal agencies to consider the potential impact of
regulations on small entities during rulemaking. The term ``small
entities'' comprises small businesses, not-for-profit organizations
that are independently owned and operated and are not dominant in their
fields, and governmental jurisdictions with populations of less than
50,000. The Coast Guard certifies under 5 U.S.C. 605(b) that this rule
will not have a significant economic impact on a substantial number of
small entities.
    While some owners or operators of vessels intending to transit the
safety zone may be small entities, for the reasons stated in section
V.A above, this rule will not have a significant economic impact on any
vessel owner or operator.
    Under section 213(a) of the Small Business Regulatory Enforcement
Fairness Act of 1996 (Pub. L. 104-121), we want to assist small
entities in understanding this rule. If the rule would affect your
small business, organization, or governmental jurisdiction and you have
questions concerning its provisions or options for compliance, please
call or email the person listed in the FOR FURTHER INFORMATION CONTACT
section.
    Small businesses may send comments on the actions of Federal
employees who enforce, or otherwise determine compliance with, Federal
regulations to the Small Business and Agriculture Regulatory
Enforcement Ombudsman and the Regional Small Business Regulatory
Fairness Boards. The Ombudsman evaluates these actions annually and
rates each agency's responsiveness to small business. If you wish to
comment on actions by employees of the Coast Guard, call 1-888-REG-FAIR
(1-888-734-3247). The Coast Guard will not retaliate against small
entities that question or complain about this rule or any policy or
action of the Coast Guard.

C. Collection of Information

    This rule will not call for a new collection of information under
the Paperwork Reduction Act of 1995 (44 U.S.C. 3501-3520).

D. Federalism and Indian Tribal Governments

    A rule has implications for federalism under Executive Order 13132,
Federalism, if it has 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. We have analyzed this rule under that order and have
determined that it is consistent with the fundamental federalism
principles and preemption requirements described in Executive Order
13132.
    Also, this rule does not have tribal implications under Executive
Order 13175, Consultation and Coordination with Indian Tribal
Governments, because it does not have a substantial direct effect on
one or more Indian tribes, on the relationship between the Federal
Government and Indian tribes, or on the distribution of power and
responsibilities between the Federal Government and Indian tribes.

E. Unfunded Mandates Reform Act

    The Unfunded Mandates Reform Act of 1995 (2 U.S.C. 1531-1538)
requires Federal agencies to assess the effects of their discretionary
regulatory actions. In particular, the Act addresses actions that may
result in the expenditure by a State, local, or tribal government, in
the aggregate, or by the private sector of $100,000,000 (adjusted for
inflation) or more in any one year. Though this rule will not result in
such an expenditure, we do discuss the effects of this rule elsewhere
in this preamble.

F. Environment

    We have analyzed this rule under Department of Homeland Security
Directive 023-01, Rev. 1, associated implementing instructions, and
Environmental Planning COMDTINST 5090.1 (series), which guide the Coast
Guard in complying with the National Environmental Policy Act of 1969
(42 U.S.C. 4321-4370f), and have determined that this action is one of
a category of actions that do not individually or cumulatively have a
significant effect on the human environment. This rule involves a
safety zone that will prohibit persons and vessels from entering,
transiting through, anchoring in, or remaining within the regulated
area during a four day visit of the Tall Ships. It is categorically
excluded from further

review under paragraph L60(a) of Appendix A, Table 1 of DHS Instruction
Manual 023-01-001-01, Rev. 1. A Record of Environmental Consideration
supporting this determination is available in the docket. For
instructions on locating the docket, see the ADDRESSES section of this
preamble.

G. Protest Activities

    The Coast Guard respects the First Amendment rights of protesters.
Protesters are asked to call or email the person listed in the FOR
FURTHER INFORMATION CONTACT section to coordinate protest activities so
that your message can be received without jeopardizing the safety or
security of people, places, or vessels.
