ACTION: Notice of proposed rulemaking (NPRM). The FAA proposes to adopt a new airworthiness directive (AD) for certain Dassault Aviation Model FALCON 7X, FALCON 900EX, and FALCON 2000EX airplanes. This proposed AD was prompted by reported occurrences of swelling of the lithiumpolymer internal and external batteries of certain electronic display units (EDUs). This proposed AD would require modifying certain EDUs and would prohibit the installation of affected parts, 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 October 7, 2024.

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 2024–0072, dated March 15, 2024 (EASA AD 2024– 0072) (also referred to as the MCAI), to correct an unsafe condition for certain Dassault Aviation Model FALCON 7X, FALCON 900EX, and FALCON 2000EX airplanes. The MCAI states that occurrences were reported of swelling of the lithium-polymer internal and external batteries of CMA–1310 EDU having part number (P/N) 100–604073– 000, with a mod-status between 2 and 6 (inclusive). The swelling occurs due to a high inrush charge and discharge current stress condition applied on a deeply discharged lithium-polymer battery. The FAA is proposing this AD to prevent internal and external battery swelling. This condition, if not corrected, could lead to the thermal Material Incorporated by Reference Under 1 CFR Part 51 EASA AD 2024–0072 specifies procedures for modifying CMA–1310 EDUs having P/N 100–604073–000 and with current mod-status between 2 and 6 (inclusive) to a mod-status 7 or higher, including a visual inspection of the external removable battery for defects (swelling) and replacement of any defective external removable battery with a new external removable battery, and updating the BIOS/EC firmware. EASA AD 2024–0072 prohibits the installation of CMA–1310 EDU having P/N 100–604073–000 and with a modstatus between 2 and 6 (inclusive) on any airplane. 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 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 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 67573 EASA AD 2024–0072 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 2024–0072 by reference in the FAA final rule. This proposed AD would, therefore, require compliance with EASA AD 2024–0072 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 2024–0072 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 2024–0072. Service information required by EASA AD 2024–0072 for compliance will be available at regulations.gov under Docket No. FAA–2024–2022 after the FAA final rule is published. Costs of Compliance The FAA estimates that this AD, if adopted as proposed, would affect 719 airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD: lotter on DSK11XQN23PROD with PROPOSALS1 ESTIMATED COSTS FOR REQUIRED ACTIONS Cost on U.S. operators Labor cost Parts cost Cost per product Up to 4 work-hours × $85 per hour = $340 ................................ $20,840 Up to $21,180 .......................... 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 Up to $15,228,420. number of aircraft that might need these on-condition actions: ESTIMATED COSTS OF ON-CONDITION ACTIONS Actions Labor cost Parts cost Cost per product Replace one external battery ............ 1 work-hour × $85 per hour = $85 .............................................................. $430 $515 VerDate Sep<11>2014 17:00 Aug 20, 2024 Jkt 262001 PO 00000 Frm 00011 Fmt 4702 Sfmt 4702 E:\FR\FM\21AUP1.SGM 21AUP1 67574 Federal Register / Vol. 89, No. 162 / Wednesday, August 21, 2024 / Proposed Rules The FAA has included all known costs in its cost estimate. According to the manufacturer, however, some or all the costs of this proposed AD may be covered under warranty, thereby reducing the cost impact on affected operators. ■ Authority for This Rulemaking § 39.13 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. lotter on DSK11XQN23PROD with PROPOSALS1 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: VerDate Sep<11>2014 17:00 Aug 20, 2024 Jkt 262001 PART 39—AIRWORTHINESS DIRECTIVES 1.

Background

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2024-0072, dated March 15, 2024 
(EASA AD 2024-0072) (also referred to as the MCAI), to correct an 
unsafe condition for certain Dassault Aviation Model FALCON 7X, FALCON 
900EX, and FALCON 2000EX airplanes. The MCAI states that occurrences 
were reported of swelling of the lithium-polymer internal and external 
batteries of CMA-1310 EDU having part number (P/N) 100-604073-000, with 
a mod-status between 2 and 6 (inclusive). The swelling occurs due to a 
high inrush charge and discharge current stress condition applied on a 
deeply discharged lithium-polymer battery. The FAA is proposing this AD 
to prevent internal and external battery swelling. This condition, if 
not corrected, could lead to the thermal runaway of a battery, possibly 
resulting in in the release of heat, smoke, fire, and explosion in the 
cockpit.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2024-2022.

Material Incorporated by Reference Under 1 CFR Part 51

    EASA AD 2024-0072 specifies procedures for modifying CMA-1310 EDUs 
having P/N 100-604073-000 and with current mod-status between 2 and 6 
(inclusive) to a mod-status 7 or higher, including a visual inspection 
of the external removable battery for defects (swelling) and 
replacement of any defective external removable battery with a new 
external removable battery, and updating the BIOS/EC firmware. EASA AD 
2024-0072 prohibits the installation of CMA-1310 EDU having P/N 100-
604073-000 and with a mod-status between 2 and 6 (inclusive) on any 
airplane.
    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 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 
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 2024-0072 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 2024-0072 by reference in the FAA 
final rule. This proposed AD would, therefore, require compliance with 
EASA AD 2024-0072 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 2024-0072 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-
0072. Service information required by EASA AD 2024-0072 for compliance 
will be available at regulations.gov under Docket No. FAA-2024-2022 
after the FAA final rule is published.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 719 airplanes of U.S. registry. The FAA estimates the following 
costs to comply with this proposed AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
               Labor cost                  Parts cost         Cost per product          Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
Up to 4 work-hours x $85 per hour = $340      $20,840   Up to $21,180..............  Up to $15,228,420.
----------------------------------------------------------------------------------------------------------------

    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 number of 
aircraft that might need these on-condition actions:

                                     Estimated Costs of On-Condition Actions
----------------------------------------------------------------------------------------------------------------
                                                                                                     Cost per
                   Actions                                 Labor cost               Parts cost       product
----------------------------------------------------------------------------------------------------------------
Replace one external battery................  1 work-hour x $85 per hour = $85...         $430             $515
----------------------------------------------------------------------------------------------------------------


[[Page 67574]]

    The FAA has included all known costs in its cost estimate. 
According to the manufacturer, however, some or all the costs of this 
proposed AD may be covered under warranty, thereby reducing the cost 
impact on affected operators.

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.

smoke, fire, and explosion in the cockpit.

(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 2024-0072.

(h) Exceptions to EASA AD 2024-0072

    (1) Where EASA AD 2024-0072 refers to its effective date, this 
AD requires using the effective date of this AD.
    (2) Paragraph (1) of EASA AD 2024-0072 specifies to ``replace 
each affected part with a serviceable part. This can be accomplished 
in accordance with the instructions of the SB.'' This AD, however, 
requires replacing that text with ``replace each affected part with 
a serviceable part in accordance with the Accomplishment 
Instructions of the SB.''
    (3) This AD does not adopt the ``Remarks'' section of EASA AD 
2024-0072.
