Background ANAC, which is the aviation authority for Brazil, has issued ANAC AD 2024–08–02, effective August 23, 2024 (ANAC AD 2024–08–02) (also referred to as the MCAI), to correct an unsafe condition for all Embraer S.A. Model EMB–545 and EMB–550 airplanes. The MCAI states there is a possibility of a jamming failure of the main door lock sensor. The FAA is proposing this AD to address a false indication of a locked door, even when it is only latched, resulting in a dormant system failure and lack of cockpit indication of the door not locked condition. The unsafe condition, if not addressed, could result in an in-flight door opening due to an operational failure. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2025–0476. 13717 Proposed AD Requirements in This NPRM This proposed AD would require accomplishing the actions specified in ANAC AD 2024–08–02 described previously, except for any differences identified as exceptions in the regulatory text of this proposed AD. Material Incorporated by Reference Under 1 CFR Part 51 ANAC AD 2024–08–02, effective August 23, 2024, specifies procedures for conducting repetitive main door sensor operational tests, repetitive lubrication of the main door sensor mechanism, and applicable oncondition actions. (The effective date of ANAC AD 2024–08–02 did not get translated to English. The effective date is August 23, 2024.) On-condition actions include adjusting or replacing the sensor or main door locked sensor support, and contacting Embraer for repair instructions. 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. Explanation of Required Compliance Information 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. 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 ANAC AD 2024–08–02 by reference in the FAA final rule. This proposed AD would, therefore, require compliance with ANAC AD 2024–08–02 in its entirety through that incorporation, except for any differences identified as exceptions in the regulatory text of this proposed AD. Material required by ANAC AD 2024– 08–02 for compliance will be available at regulations.gov under Docket No. FAA–2025–0476 after the FAA final rule is published. Costs of Compliance The FAA estimates that this AD, if adopted as proposed, would affect 296 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 Up to 4 work-hours × $85 per hour = $340 ....................................................... The FAA estimates the following costs to do any necessary on-condition action that would be required based on $0 Cost per product Up to $340 ................ the results of any required actions. The FAA has no way of determining the Cost on U.S. operators Up to $100,640. number of aircraft that might need this on-condition action: khammond on DSK9W7S144PROD with PROPOSALS ESTIMATED COSTS OF ON-CONDITION ACTIONS Labor cost Parts cost Up to 7 work-hours × $85 per hour = $595 ................................. Up to $19,845.27 ................................ The FAA has received no definitive data on which to base the cost estimates for the on-condition repairs specified in this proposed AD. The FAA has included all known costs in its cost estimate. According to the manufacturer, however, some or all VerDate Sep<11>2014 16:00 Mar 25, 2025 Jkt 265001 of the costs of this proposed AD may be covered under warranty, thereby reducing the cost impact on affected operators. PO 00000 Frm 00013 Fmt 4702 Sfmt 4702 Cost per product Up to $20,440.27. 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 E:\FR\FM\26MRP1.SGM 26MRP1 13718 Federal Register / Vol. 90, No. 57 / Wednesday, March 26, 2025 / Proposed Rules 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 1.

Background

    ANAC, which is the aviation authority for Brazil, has issued ANAC 
AD 2024-08-02, effective August 23, 2024 (ANAC AD 2024-08-02) (also 
referred to as the MCAI), to correct an unsafe condition for all 
Embraer S.A. Model EMB-545 and EMB-550 airplanes. The MCAI states there 
is a possibility of a jamming failure of the main door lock sensor.
    The FAA is proposing this AD to address a false indication of a 
locked door, even when it is only latched, resulting in a dormant 
system failure and lack of cockpit indication of the door not locked 
condition. The unsafe condition, if not addressed, could result in an 
in-flight door opening due to an operational failure.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2025-0476.

Material Incorporated by Reference Under 1 CFR Part 51

    ANAC AD 2024-08-02, effective August 23, 2024, specifies procedures 
for conducting repetitive main door sensor operational tests, 
repetitive lubrication of the main door sensor mechanism, and 
applicable on-condition actions. (The effective date of ANAC AD 2024-
08-02 did not get translated to English. The effective date is August 
23, 2024.) On-condition actions include adjusting or replacing the 
sensor or main door locked sensor support, and contacting Embraer for 
repair instructions.
    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 ANAC AD 2024-08-02 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 ANAC AD 2024-08-02 by reference in the FAA 
final rule. This proposed AD would, therefore, require compliance with 
ANAC AD 2024-08-02 in its entirety through that incorporation, except 
for any differences identified as exceptions in the regulatory text of 
this proposed AD. Material required by ANAC AD 2024-08-02 for 
compliance will be available at regulations.gov under Docket No. FAA-
2025-0476 after the FAA final rule is published.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 296 airplanes of U.S. registry. The FAA estimates the following 
costs to comply with this proposed AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
                                    Parts
           Labor cost                cost           Cost per product               Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
Up to 4 work-hours x $85 per             $0  Up to $340...................  Up to $100,640.
 hour = $340.
----------------------------------------------------------------------------------------------------------------

    The FAA estimates the following costs to do any necessary on-
condition action 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 this on-condition action:

                 Estimated Costs of On-Condition Actions
------------------------------------------------------------------------
           Labor cost                 Parts cost       Cost per product
------------------------------------------------------------------------
Up to 7 work-hours x $85 per      Up to $19,845.27..  Up to $20,440.27.
 hour = $595.
------------------------------------------------------------------------

    The FAA has received no definitive data on which to base the cost 
estimates for the on-condition repairs specified in this proposed AD.
    The FAA has included all known costs in its cost estimate. 
According to the manufacturer, however, some or all of 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

[[Page 13718]]

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 adding the following new airworthiness 
directive:

Embraer S.A.: Docket No. FAA-2025-0476; Project Identifier MCAI-
2024-00482-T.

(a) Comments Due Date

    The FAA must receive comments on this airworthiness directive 
(AD) by May 12, 2025.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to all Embraer S.A. Model EMB-545 and EMB-550 
airplanes, certificated in any category.

(d) Subject

    Air Transport Association (ATA) of America Code 52, Doors.

(e) Unsafe Condition

    This AD was prompted by a jamming failure of the main door lock 
sensor. This jamming could result in a false indication of a locked 
door, even when it is only latched, resulting in a dormant system 
failure and lack of cockpit indication of the door not locked 
condition. The unsafe condition, if not addressed, could result in a 
door opening in flight due to an operational failure.

(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, Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o 
Civil (ANAC) AD 2024-08-02, effective August 23, 2024 (ANAC AD 2024-
08-02).

(h) Exceptions to ANAC AD 2024-08-02

    (1) Where ANAC AD 2024-08-02 refers to its effective date, this 
AD requires using the effective date of this AD.
    (2) Where ANAC AD 2024-08-02 specifies on-condition actions, 
this AD requires performing the applicable on-condition actions 
before further flight.
    (3) Where ANAC AD 2024-08-02 specifies to discard parts, this AD 
does not require that action.
    (4) Where paragraph (c) of ANAC AD 2024-08-02 specifies to 
repeat the operational test ``each 12 months,'' this AD requires 
replacing that text with ``at intervals not to exceed 12 months.''
    (5) Where paragraph (e) of ANAC AD 2024-08-02 specifies to 
repeat the lubrication ``each 24 months'' this AD requires replacing 
that text with ``at intervals not to exceed 24 months.''
    (6) This AD does not adopt paragraph (f) of ANAC AD 2024-08-02.
