E:\FR\FM\13MYP1.SGM 13MYP1 41366 Federal Register / Vol. 89, No. 93 / Monday, May 13, 2024 / Proposed Rules Background The FAA issued AD 2022–16–06, Amendment 39–22135 (87 FR 51588, August 23, 2022) (AD 2022–16–06), for certain Airbus SAS Model A330–201, –202, –203, –223, –223F, –243, –243F, –301, –302, –303, –321, –322, –323, –341, –342, –343, and –941 airplanes; and all Model A340–211, –212, –213, –311, –312, and –313 airplanes. AD 2022–16–06 was prompted by an MCAI originated by EASA, which is the Technical Agent for the Member States of the European Union. EASA issued AD 2022–0039, dated March 8, 2022, to correct an unsafe condition. AD 2022–16–06 requires modifying the THSA installation, implementing the ELSD wiring provisions, and installing and activating the ELSD. The FAA issued AD 2022–16–06 to address damage on the upper THSA SLP attachment, with consequent mechanical disconnection of the THSA, possibly resulting in loss of control of the airplane. Actions Since AD 2022–16–06 Was Issued Since the FAA issued AD 2022–16– 06, EASA superseded AD 2022–0039, dated March 8, 2022 (EASA AD 2022– 0039), and issued EASA AD 2024–0016, dated January 11, 2024 (EASA AD 2024–0016) (also referred to as the MCAI), to correct an unsafe condition for certain Airbus SAS Model A330– 201, –202, –203, –223, –223F, –243, –243F, –301, –302, –303, –321, –322, –323, –341, –342, –343, and 0–941 airplanes; and all Airbus SAS Model A340–211, –212, –213, –311, –312, and –313 airplanes. The MCAI states that it has been determined that the actions specified in EASA AD 2022–0039 cannot be accomplished on certain affected airplanes. Airbus subsequently developed additional instructions and corrections for the procedures. In certain circumstances, there may be no indication to the flightcrew of the engagement of the upper secondary load path (SLP) of the THSA. This condition, if not addressed, could lead to damage on the upper THSA SLP attachment, with consequent mechanical disconnection of the THSA, resulting in loss of control of the airplane. The FAA is proposing this AD to address the unsafe condition on these products. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2024–1294. Explanation of Retained Requirements Although this proposed AD does not explicitly restate the requirements of AD 2022–16–06, this proposed AD would retain all of the requirements of AD 2022–16–06. Those requirements are referenced in EASA AD 2024–0016, which, in turn, is referenced in paragraph (g) of this proposed AD. Related Service Information Under 1 CFR Part 51 EASA AD 2024–0016 specifies procedures for installing and activating the ELSD and wiring provisions, and doing additional work that includes additional instructions and corrections for certain airplanes. This material 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 referenced above. The FAA is issuing this NPRM after determining that the unsafe condition described previously is likely to exist or develop in other products of the same type design. Proposed AD Requirements in This NPRM This proposed AD would retain all requirements of AD 2022–16–06. This proposed AD would also require additional work for certain airplanes. This proposed AD would require accomplishing the actions specified in EASA AD 2024–0016 described previously, except for any differences identified as exceptions in the regulatory text of this proposed AD. Explanation of Required Compliance Information In the FAA’s ongoing efforts to improve the efficiency of the AD process, the FAA developed a process to use some civil aviation authority (CAA) ADs as the primary source of information for compliance with requirements for corresponding FAA ADs. The FAA has been coordinating this process with manufacturers and CAAs. As a result, the FAA proposes to incorporate EASA AD 2024–0016 by reference in the FAA final rule. This proposed AD would, therefore, require compliance with EASA AD 2024–0016 in its entirety through that incorporation, except for any differences identified as exceptions in the regulatory text of this proposed AD. Using common terms that are the same as the heading of a particular section in EASA AD 2024–0016 does not mean that operators need comply only with that section. For example, where the AD requirement refers to ‘‘all required actions and compliance times,’’ compliance with this AD requirement is not limited to the section titled ‘‘Required Action(s) and Compliance Time(s)’’ in EASA AD 2024–0016. Service information required by EASA AD 2024–0016 for compliance will be available at regulations.gov under Docket No. FAA–2024–1294 after the FAA final rule is published. Costs of Compliance The FAA estimates that this AD, if adopted as proposed, would affect 120 airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD: ESTIMATED COSTS FOR REQUIRED ACTIONS lotter on DSK11XQN23PROD with PROPOSALS1 Action Labor cost Retained actions from AD 2022– 16–06. New proposed actions ................. 57 work-hours × $85 per hour = $4,845. 5 work-hours × $85 per hour = $425. According to the manufacturer, some or all of the costs of this proposed AD may be covered under warranty, thereby reducing the cost impact on affected VerDate Sep<11>2014 21:32 May 10, 2024 Jkt 262001 Cost per product Up to $23,000 ............

The FAA does not control warranty coverage for affected individuals. As a result, the FAA has PO 00000 Frm 00020 Fmt 4702 Cost on U.S. operators Parts cost Sfmt 4702 included all known costs in the cost estimate. E:\FR\FM\13MYP1.SGM 13MYP1 Federal Register / Vol. 89, No. 93 / Monday, May 13, 2024 / Proposed Rules 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.

Notice of proposed rulemaking. AGENCY: ACTION: The Coast Guard is proposing to establish a temporary special local regulation in the navigable waters of San Francisco Bay for the San Francisco Sail Grand Prix, Season 4 race periods on July 11, 2024, through July 14, 2024. This special local regulation is necessary to ensure the safety of mariners transiting the area from the dangers associated with high-speed sailing activities. This proposed rulemaking would temporarily prohibit entering, transiting through, anchoring, blocking, or loitering within the event area near the Golden Gate Bridge and Alcatraz Island, unless authorized. DATES: Comments and related material must be received by the Coast Guard on or before June 12, 2024. ADDRESSES: You may submit comments identified by docket number USCG– 2024–0378 using the Federal DecisionMaking Portal at https:// www.regulations.gov. See the ‘‘Public Participation and Request for Comments’’ portion of the SUPPLEMENTARY INFORMATION section for further instructions on submitting comments.

FOR FURTHER INFORMATION CONTACT: If you have questions about this proposed rulemaking, call or email Lieutenant William K. Harris, U.S. Coast Guard Sector San Francisco, Waterways Management Division; telephone 415– 399–7443, email SFWaterways@ uscg.mil. SUPPLEMENTARY INFORMATION: I. Table of Abbreviations CFR Code of Federal Regulations DHS Department of Homeland Security FR Federal Register NPRM Notice of proposed rulemaking § Section COTP Captain of the Port PATCOM Patrol Commander U.S.C. United States Code II. Background, Purpose, and Legal Basis On February 6, 2024, the Silverback Pacific Company notified the Coast Guard of the intention to conduct the ‘‘Sail Grand Prix, Season 4’’ in the San Francisco Bay. Sail Grand Prix (SailGP) is a sailing league featuring world-class sailors racing 50-foot foiling catamarans. The 2023–2024 season started June 16, 2023, and the season will conclude with the San Francisco Bay race in July 2024. In San Francisco, they propose to take advantage of the natural amphitheater that the central bay and city waterfront provide. SailGP has applied for a Marine Event Permit to hold the race event on the waters of the San Francisco Bay. At this time, the Coast Guard has not approved the Marine Event Permit and is still evaluating the application. If the permit is approved, however, we anticipate that a special local regulation may be necessary to ensure public safety during the race. To provide adequate time for public input, we are proposing this special local regulation prior to a decision on the Marine Event Permit. The SailGP event has previously been conducted in San Francisco Bay and each time the Coast Guard solicited input from maritime stakeholders to better understand the nature of commercial and recreational activities on the San Francisco Bay. As done in previous years panning, the Coast Guard will participate in local Harbor Safety Committee (HSC) meetings to meet with stakeholders, obtain information, and gather feedback on approaches to enact the regulations in connection with the SailGP. These regulations are needed to keep persons and vessels away from the sailing race vessels, which exhibit PO 00000 Frm 00022 Fmt 4702 Sfmt 4702 unpredictable maneuverability and have a demonstrated likelihood during the simulation of racing scenarios for capsizing. The proposed special local regulation would help prevent injuries and property damage that may be caused upon impact by these fastmoving vessels. The provisions of this temporary special local regulation would not exempt racing vessels from any federal, state, or local laws or regulations, including Nautical Rules of the Road. The Coast Guard proposes this rulemaking under authority in 46 U.S.C. 70041. Under 33 CFR 100.35, the Coast Guard District Commander has authority to promulgate certain special local regulations deemed necessary to ensure the safety of life on the navigable waters immediately before, during, and immediately after an approved regatta. Pursuant to 33 CFR 1.05–1(i), the Commander of Coast Guard District 11 has delegated to the COTP San Francisco the responsibility of issuing such regulations. III. Discussion of Proposed Rule The COTP San Francisco proposes to establish a special local regulation associated with the SailGP race event from noon to 5:30 p.m. each day from July 11, 2024, through July 14, 2024. The areas regulated by this special local regulation would be east of the Golden Gate Bridge, south of Alcatraz Island, west of Treasure Island, and in the vicinity of the city of San Francisco waterfront. The Coast Guard proposes establishing an Official Practice Box Area, an Official Race Box Area, and a Spectator Area. An image of these proposed regulated areas may be found in the docket. The special local regulation will cover all navigable waters of the San Francisco Bay, from surface to bottom, within the area formed by connecting the following latitude and longitude points in the following order: 37°48′24.3″ N, 122°27′53.5″ W; thence to 37°49′15.6″ N, 122°27′58.1″ W; thence to 37°49′28.9″ N, 122°25′52.1″ W; thence to 37°49′7.5″ N, 122°25′13″ W; thence to 37°48′42″ N, 122°25′13″ W; thence to 37°48′30.5″ N, 122°26′22.6″ W; thence along the shore to 37°48′26.9″ N, 122°26′50.5″ W and thence to the point of beginning. Located within this footprint, there will be three separate regulated areas: Zone ‘‘A’’, the Official Practice Box Area; Zone ‘‘B’’, the Official Race Box Area; and Zone ‘‘C’’, the Spectator Area. Zone ‘‘A’’, the Official Practice Box Area, will be marked by colored visual markers, The position of these markers will be specified via Local Notice to Mariners at least two weeks prior to the E:\FR\FM\13MYP1.SGM 13MYP1

Airworthiness Directives; Airbus SAS Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD) 
2022-16-06, which applies to certain Airbus SAS Model A330-200, A330-
200 Freighter, A330-300, and A330-900 series airplanes; and all Model 
A340-200 and A340-300 series airplanes. AD 2022-16-06 requires 
modifying the Trimmable Horizontal Stabilizer Actuator (THSA) 
installation, implementing the electrical load sensing device (ELSD) 
wiring provisions, and installing and activating the ELSD. Since the 
FAA issued AD 2022-16-06, it has been determined that the required 
actions cannot be accomplished on certain airplanes, and additional 
instructions and corrections have been developed. This proposed AD 
would continue to require the actions in AD 2022-16-06 with certain 
revised procedures and would require additional work for certain 
airplanes, as specified in a European Union Aviation Safety Agency 
(EASA) AD, which is proposed for incorporation by reference (IBR). The 
FAA is proposing this AD to address the unsafe condition on these 
products.

DATES: The FAA must receive comments on this proposed AD by June 27, 
2024.

Background

    The FAA issued AD 2022-16-06, Amendment 39-22135 (87 FR 51588, 
August 23, 2022) (AD 2022-16-06), for certain Airbus SAS Model A330-
201, -202, -203, -223, -223F, -243, -243F, -301, -302, -303, -321, -
322, -323, -341, -342, -343, and -941 airplanes; and all Model A340-
211, -212, -213, -311, -312, and -313 airplanes. AD 2022-16-06 was 
prompted by an MCAI originated by EASA, which is the Technical Agent 
for the Member States of the European Union. EASA issued AD 2022-0039, 
dated March 8, 2022, to correct an unsafe condition.
    AD 2022-16-06 requires modifying the THSA installation, 
implementing the ELSD wiring provisions, and installing and activating 
the ELSD. The FAA issued AD 2022-16-06 to address damage on the upper 
THSA SLP attachment, with consequent mechanical disconnection of the 
THSA, possibly resulting in loss of control of the airplane.

Actions Since AD 2022-16-06 Was Issued

    Since the FAA issued AD 2022-16-06, EASA superseded AD 2022-0039, 
dated March 8, 2022 (EASA AD 2022-0039), and issued EASA AD 2024-0016, 
dated January 11, 2024 (EASA AD 2024-0016) (also referred to as the 
MCAI), to correct an unsafe condition for certain Airbus SAS Model 
A330-201, -202, -203, -223, -223F, -243, -243F, -301, -302, -303, -321, 
-322, -323, -341, -342, -343, and 0-941 airplanes; and all Airbus SAS 
Model A340-211, -212, -213, -311, -312, and -313 airplanes. The MCAI 
states that it has been determined that the actions specified in EASA 
AD 2022-0039 cannot be accomplished on certain affected airplanes. 
Airbus subsequently developed additional instructions and corrections 
for the procedures. In certain circumstances, there may be no 
indication to the flightcrew of the engagement of the upper secondary 
load path (SLP) of the THSA. This condition, if not addressed, could 
lead to damage on the upper THSA SLP attachment, with consequent 
mechanical disconnection of the THSA, resulting in loss of control of 
the airplane.
    The FAA is proposing this AD to address the unsafe condition on 
these products. You may examine the MCAI in the AD docket at 
regulations.gov under Docket No. FAA-2024-1294.

Explanation of Retained Requirements

    Although this proposed AD does not explicitly restate the 
requirements of AD 2022-16-06, this proposed AD would retain all of the 
requirements of AD 2022-16-06. Those requirements are referenced in 
EASA AD 2024-0016, which, in turn, is referenced in paragraph (g) of 
this proposed AD.

Related Service Information Under 1 CFR Part 51

    EASA AD 2024-0016 specifies procedures for installing and 
activating the ELSD and wiring provisions, and doing additional work 
that includes additional instructions and corrections for certain 
airplanes. This material 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 
referenced above. The FAA is issuing this NPRM after determining that 
the unsafe condition described previously is likely to exist or develop 
in other products of the same type design.

Proposed AD Requirements in This NPRM

    This proposed AD would retain all requirements of AD 2022-16-06. 
This proposed AD would also require additional work for certain 
airplanes. This proposed AD would require accomplishing the actions 
specified in EASA AD 2024-0016 described previously, except for any 
differences identified as exceptions in the regulatory text of this 
proposed AD.

Explanation of Required Compliance Information

    In the FAA's ongoing efforts to improve the efficiency of the AD 
process, the FAA developed a process to use some civil aviation 
authority (CAA) ADs as the primary source of information for compliance 
with requirements for corresponding FAA ADs. The FAA has been 
coordinating this process with manufacturers and CAAs. As a result, the 
FAA proposes to incorporate EASA AD 2024-0016 by reference in the FAA 
final rule. This proposed AD would, therefore, require compliance with 
EASA AD 2024-0016 in its entirety through that incorporation, except 
for any differences identified as exceptions in the regulatory text of 
this proposed AD. Using common terms that are the same as the heading 
of a particular section in EASA AD 2024-0016 does not mean that 
operators need comply only with that section. For example, where the AD 
requirement refers to ``all required actions and compliance times,'' 
compliance with this AD requirement is not limited to the section 
titled ``Required Action(s) and Compliance Time(s)'' in EASA AD 2024-
0016. Service information required by EASA AD 2024-0016 for compliance 
will be available at regulations.gov under Docket No. FAA-2024-1294 
after the FAA final rule is published.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 120 airplanes of U.S. registry. The FAA estimates the following 
costs to comply with this proposed AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
                                                                                                 Cost on U.S.
             Action                   Labor cost          Parts cost       Cost per product        operators
----------------------------------------------------------------------------------------------------------------
Retained actions from AD 2022-16- 57 work-hours x     Up to $23,000.....  Up to $27,845.....  Up to $3,341,400.
 06.                               $85 per hour =
                                   $4,845.
New proposed actions............  5 work-hours x $85  $43,966...........  $44,391...........  Up to $5,326,920.
                                   per hour = $425.
----------------------------------------------------------------------------------------------------------------

    According to the manufacturer, some or all of the costs of this 
proposed AD may be covered under warranty, thereby reducing the cost 
impact on affected individuals. The FAA does not control warranty 
coverage for affected individuals. As a result, the FAA has included 
all known costs in the cost estimate.

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

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:
0
a. Removing Airworthiness Directive (AD) 2022-16-06, Amendment 39-22135 
(87 FR 51588, August 23, 2022); and
0
b. Adding the following new AD:

Airbus SAS: Docket No. FAA-2024-1294; Project Identifier MCAI-2024-
00042-T.

(a) Comments Due Date

    The FAA must receive comments on this airworthiness directive 
(AD) by June 27, 2024.

(b) Affected ADs

    This AD replaces AD 2022-16-06, Amendment 39-22135 (87 FR 51588, 
August 23, 2022) (AD 2022-16-06).

(c) Applicability

    This AD applies to Airbus SAS airplanes specified in paragraphs 
(c)(1) and (2) of this AD, certificated in any category, as 
identified in European Union Aviation Safety Agency (EASA) AD 2024-
0016, dated January 11, 2024 (EASA AD 2024-0016).

-302, -303, -321, -322, -323, -341, -342, -343, and -941 airplanes.
    (2) Model A340-211, -212, -213, -311, -312, and -313 airplanes.

(d) Subject

    Air Transport Association (ATA) of America Code 27, Flight 
Controls.

(e) Unsafe Condition

    This AD was prompted by tests that demonstrated that when the 
upper secondary load path (SLP) of the trimmable horizontal 
stabilizer actuator (THSA) is engaged, the THSA might not stall, 
with consequently no indication of SLP engagement, and by the recent 
determination that the required actions of AD 2022-16-06 cannot be 
accomplished on certain airplanes. The FAA is issuing this AD to 
prevent damage on the upper THSA SLP attachment, with consequent 
mechanical disconnection of the THSA, that could result in loss of 
control of the airplane.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Requirements

    Except as specified in paragraph (h) of this AD: Comply with all 
required actions and compliance times specified in, and in 
accordance with, EASA AD 2024-0016.

(h) Exceptions to EASA AD 2024-0016

    (1) Where EASA AD 2024-0016 refers to ``22 March 2022 [the 
effective date of EASA AD 2022-0039],'' this AD requires using 
September 27, 2022 (the effective date of AD 2022-16-06).
    (2) Where EASA AD 2024-0016 refers to its effective date, this 
AD requires using the effective date of this AD.
    (3) Where paragraph (1) of EASA AD 2024-0016 applies to 
airplanes in ``Group 1,'' this AD requires replacing that text with 
``Group 1 airplanes, except as specified in paragraph (3)'' of EASA 
AD 2024-0016.
    (4) This AD does not adopt the ``Remarks'' section of EASA AD 
2024-0016.

    (3) Required for Compliance (RC): Except as required by 
paragraph (i)(2) of this AD, if any service information contains 
procedures or tests that are identified as RC, those procedures and 
tests must be done to comply with this AD; any procedures or tests 
that are not identified as RC are recommended. Those procedures and 
tests that are not identified as RC may be deviated from using 
accepted methods in accordance with the operator's maintenance or 
inspection program without obtaining approval of an AMOC, provided 
the procedures and tests identified as RC can be done and the
