[Docket No. FAA-2025-0010; Project Identifier MCAI-2024-00270-T]
RIN 2120-AA64
 AGENCY: Federal Aviation Administration (FAA), DOT.
 ACTION: Notice of proposed rulemaking (NPRM).
 SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD) 2006-20-08, which applies to all Embraer S.A. Model EMB-145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP airplanes. AD 2006-20-08 requires repetitive inspections to detect cracking or failure of the rod ends and fittings of the aileron power control actuator (PCA) and corrective actions if necessary, and provides an optional terminating action. Since the FAA issued AD 2006-20-08, it has been determined that there was an error in identifying a maintenance task number. This proposed AD would continue to require the actions in AD 2006-20-08 and corrects an error in a task number, as specified in an Agência Nacional de Aviação Civil (ANAC) 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 March 17, 2025.

                     Any commentary that the FAA receives which is not specifically designated as CBI will be placed in the public docket for this rulemaking. Background The FAA issued AD 2006-20-08, Amendment 39-14777 (71 FR 58487, October 4, 2006) (AD 2006-20-08), for all Embraer Model EMB-145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP airplanes. AD 2006-20-08 was prompted by an MCAI originated by Departmento de Aviacao Civil (DAC), which was the aviation authority for Brazil (now known as ANAC). DAC issued AD 1999-02-01R6, dated June 21, 2004, to correct an unsafe condition. AD 2006-20-08 requires repetitive inspections to detect cracking or failure/breaking of the rod ends and fittings of the aileron PCA, corrective actions if necessary, and provides an optional terminating action for the requirements. The FAA issued AD 2006-20-08 to detect and correct cracking or breaking of the rod ends and connecting fittings of the aileron PCA, which could result in reduced controllability of the airplane. Actions Since AD 2006-20-08 Was Issued Since the FAA issued AD 2006-20-08, ANAC superseded AD 1999-02-01R6, dated June 21, 2004, and issued ANAC AD 1999-02-01R7, effective May 6, 2024; corrected October 11, 2024 (ANAC AD 1999-02-01R7) (also referred to as the MCAI), to correct an unsafe condition for all Embraer S.A. Model EMB-145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP airplanes. The MCAI states that after ANAC AD 1999-02-01R6 was issued it was identified that the visual inspection task number referenced on requirement (c) of that AD (AMM TASK 27-12-01-212-002-A00, “Aileron PCA Rod Ends/Fitting, Lugs for Integrity and General Condition”) was incorrect. ANAC AD 1999-02-01R7 was issued to replace the task reference to MRB-145/1150 TASK 27-12-01-212-002-A05. For airplanes identified in paragraph (c) of ANAC AD 1999-02-01R7, accomplishing repetitive inspections as specified in MRB-145/1150 TASK 27-12-01-212-002-A05 are necessary to address the unsafe condition. The FAA is proposing this AD to detect and correct cracking or breaking of the rod ends and connecting fittings of the aileron PCA, which could result in reduced controllability of the airplane. You may examine the MCAI in the AD docket at 
                    *regulations.gov*
                     under Docket No. FAA-2025-0010. Explanation of Retained Requirements Although this proposed AD does not explicitly restate the requirements of AD 2006-20-08, this proposed AD would retain certain requirements of AD 2006-20-08. Those requirements are referenced in ANAC AD 1999-02-01R7, which, in turn, is referenced in paragraph (g) of this proposed AD. Material Incorporated by Reference Under 1 CFR Part 51 ANAC AD 1999-02-01R7 specifies procedures for repetitive inspections to detect cracking and failure of the rod ends and PCA fittings of the aileron PCA and corrective actions if necessary, and provides an optional terminating action. Corrective actions include replacing cracked and failed rod ends and PCA fittings.

                     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 certain requirements of AD 2006-20-08. This proposed AD would require accomplishing the actions specified in ANAC AD 1999-02-01R7 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 1999-02-01R7 by reference in the FAA final rule. This proposed AD would, therefore, require compliance with ANAC AD 1999-02-01R7 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 1999-02-01R7 for compliance will be available at 
                    *regulations.gov*
                     under Docket No. FAA-2025-0010 after the FAA final rule is published. Costs of Compliance The FAA estimates that this AD, if adopted as proposed, would affect 272 airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD: Estimated Costs for Required 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. 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.
