Any commentary that the FAA receives which is not specifically designated as CBI will be placed in the public docket for this rulemaking. Background EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2024– 0092R1, dated July 10, 2024 (EASA AD 2024–0092R1) (also referred to as the MCAI), to correct an unsafe condition for certain Airbus SAS Model A300 series, A300–600 series, and A310 series airplanes. The MCAI states that investigations found cracks on the MDCD actuator bearing fitting caused by fatigue. There is no unsafe condition during flight when the cargo door if fully closed, latched, and locked. However, if not detected and corrected, this cracking could lead to MDCD undamped free fall from the open position during MDCD operations or during cargo loading/off-loading, resulting in injury to people on the ground. 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–2024–2556. Material Incorporated by Reference Under 1 CFR Part 51 EASA AD 2024–0092R1 specifies procedures for an operational limitation to the MDCD opening angle, repetitive DET of the MDCD actuator bearing fittings, and replacement of both MDCD actuator bearing fittings if any crack is found on any MDCD actuator bearing fitting. 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 require accomplishing the actions specified in 100927 EASA AD 2024–0092R1 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 2024–0092R1 by reference in the FAA final rule. This proposed AD would, therefore, require compliance with EASA AD 2024– 0092R1 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 2024–0092R1 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 2024–0092R1. Material required by EASA AD 2024– 0092R1 for compliance will be available at regulations.gov under Docket No. FAA–2024–2556 after the FAA final rule is published. Interim Action The FAA considers that this proposed AD would be an interim action. If final action is later identified, the FAA might consider further rulemaking then. Costs of Compliance The FAA estimates that this AD, if adopted as proposed, would affect 128 airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD: khammond on DSK9W7S144PROD with PROPOSALS ESTIMATED COSTS FOR REQUIRED ACTIONS Labor cost Parts cost Cost per product Cost on U.S. operators 1 work-hour × $85 per hour = $85 .............................................................................................. $0 $85 $10,880 The FAA estimates the following costs to do any necessary on-condition VerDate Sep<11>2014 17:50 Dec 12, 2024 Jkt 265001 actions that would be required based on the results of any required actions. The PO 00000 Frm 00007 Fmt 4702 Sfmt 4702 FAA has no way of determining the E:\FR\FM\13DEP1.SGM 13DEP1 100928 Federal Register / Vol. 89, No. 240 / Friday, December 13, 2024 / Proposed Rules number of aircraft that might need this on-condition action: ESTIMATED COSTS OF ON-CONDITION ACTIONS Labor cost Parts cost Cost per product 500 work-hours × $85 per hour = $42,500 ..................................................................................................... $34,600 $77,100 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. khammond on DSK9W7S144PROD with PROPOSALS List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.

Airworthiness Directives; Airbus SAS Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for certain Airbus SAS Model A300 series airplanes; Model A300 B4-600, 
B4-600R, and F4-600R series airplanes, and Model A300 C4-605R Variant F 
airplanes (collectively called Model A300-600 series airplanes); and 
Model A310 series airplanes. This proposed AD was prompted by 
investigations that found cracks on the main deck cargo door (MDCD) 
actuator bearing fitting caused by fatigue. This proposed AD would 
require an operational limitation to the MDCD opening angle, repetitive 
detailed visual inspection (DET) of the MDCD actuator bearing fittings, 
and replacement if any cracks are found, 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 January 27, 
2025.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

commentary that the FAA receives which is not specifically designated 
as CBI will be placed in the public docket for this rulemaking.

Background

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2024-0092R1, dated July 10, 2024 
(EASA AD 2024-0092R1) (also referred to as the MCAI), to correct an 
unsafe condition for certain Airbus SAS Model A300 series, A300-600 
series, and A310 series airplanes. The MCAI states that investigations 
found cracks on the MDCD actuator bearing fitting caused by fatigue. 
There is no unsafe condition during flight when the cargo door if fully 
closed, latched, and locked. However, if not detected and corrected, 
this cracking could lead to MDCD undamped free fall from the open 
position during MDCD operations or during cargo loading/off-loading, 
resulting in injury to people on the ground.
    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-2024-2556.

Material Incorporated by Reference Under 1 CFR Part 51

    EASA AD 2024-0092R1 specifies procedures for an operational 
limitation to the MDCD opening angle, repetitive DET of the MDCD 
actuator bearing fittings, and replacement of both MDCD actuator 
bearing fittings if any crack is found on any MDCD actuator bearing 
fitting.
    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 require accomplishing the actions specified 
in EASA AD 2024-0092R1 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 2024-0092R1 by reference in the FAA 
final rule. This proposed AD would, therefore, require compliance with 
EASA AD 2024-0092R1 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 2024-0092R1 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-
0092R1. Material required by EASA AD 2024-0092R1 for compliance will be 
available at regulations.gov under Docket No. FAA-2024-2556 after the 
FAA final rule is published.

Interim Action

    The FAA considers that this proposed AD would be an interim action. 
If final action is later identified, the FAA might consider further 
rulemaking then.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 128 airplanes of U.S. registry. The FAA estimates the following 
costs to comply with this proposed AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
                                                                                    Cost per       Cost on U.S.
                          Labor cost                              Parts cost        product         operators
----------------------------------------------------------------------------------------------------------------
1 work-hour x $85 per hour = $85.............................              $0              $85          $10,880
----------------------------------------------------------------------------------------------------------------

    The FAA estimates the following costs to do any necessary on-
condition actions that would be required based on the results of any 
required actions. The FAA has no way of determining the

[[Page 100928]]

number of aircraft that might need this on-condition action:

                 Estimated Costs of On-Condition Actions
------------------------------------------------------------------------
            Labor cost                 Parts cost      Cost per product
------------------------------------------------------------------------
500 work-hours x $85 per hour =            $34,600              $77,100
 $42,500..........................
------------------------------------------------------------------------

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.

accordance with, European Union Aviation Safety Agency (EASA) AD 
2024-0092R1, dated July 10, 2024 (EASA AD 2024-0092R1).

(h) Exceptions to EASA AD 2024-0092R1

    (1) Where EASA AD 2024-0092R1 refers to April 26, 2024 (the 
effective date of the original issue of EASA AD 2024-0092R1), this 
AD requires using the effective date of this AD.
    (2) This AD does not adopt the ``Remarks'' section of EASA AD 
2024-0092R1.

(i) No Reporting Requirement

    Although the material referenced in EASA AD 2024-0092R1 
specifies to submit certain information to the manufacturer, this AD 
does not include that requirement.

(j) Additional AD Provisions

    The following provisions also apply to this AD:
