 ACTION: Final rule.
 SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2020-12-08 for all Embraer S.A. Model EMB-505 airplanes. AD 2020-12-08 required inspections of the mass-balance weights of the elevators, ailerons, and rudder (flight control surfaces) and their attachment parts, and corrective actions if necessary, and revising the airworthiness limitation section (ALS) of the maintenance manual or instructions for continued airworthiness to incorporate new airworthiness limitations. This AD retains the actions required by AD 2020-12-08 and requires, for certain airplanes, cleaning and weighing certain mass-balances and installation or replacement, as applicable; and for certain other mass-balances for certain airplanes, replacement of those mass-balances. This AD was prompted by a determination that new applicable airplane serial numbers and new criteria for the replacement of affected parts are necessary. The FAA is issuing this AD to address the unsafe condition on these products.
 DATES: This AD is effective April 13, 2022. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of April 13, 2022. The Director of the Federal Register approved the incorporation by reference of a certain other publication listed in this AD as of July 1, 2020 (85 FR 36312, June 16, 2020).

SUPPLEMENTARY INFORMATION: Background The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2020-12-08, Amendment 39-21143 (85 FR 36312, June 16, 2020), (AD 2020-12-08). AD 2020-12-08 applied to all Embraer S.A. (type certificate previously held by Empresa Brasileira de Aeronáutica S.A.) Model EMB-505 airplanes and required for certain serial-numbered airplanes, inspecting the mass-balance weights of the flight control surfaces and their attachment parts for corrosion and fragmentation, and taking corrective actions if necessary, including sending inspection results to Embraer. For all airplanes, AD 2020-12-08 required revising the airworthiness limitation section of the maintenance manual or instructions for continued airworthiness to incorporate new airworthiness limitations. The NPRM published in the 
                    **Federal Register**
                     on September 9, 2021 (86 FR 50487). The NPRM was prompted by Brazilian AD 2020-09-01, dated September 8, 2020 (referred to after this as “the MCAI”), issued by the Agência Nacional de Aviação Civil (ANAC), which is the aviation authority for Brazil. The MCAI states: 
 
 It has been found the occurrence of corrosion in the mass-balance weights of the control surfaces. The corrosion may lead to loss of mass or detachment of the mass-balance weights, resulting in an unbalance control surface, which, in conjunction with certain flight conditions, could lead to flutter and possible loss of airplane control. Since this condition may occur in other airplanes of the same type and affects flight safety, a corrective action is required. Thus, sufficient reason exists to request compliance with this [ANAC] AD in the indicated time limit. After [ANAC] EAD [Emergency AD] 2020-01-01 was released, a reassessment of the unsafe condition by Embraer and, subsequently, the SB [service bulletin] 505-55-0004, revisions 0 and 1, dated March 25th, 2020 and June 24, 2020, respectively, expanding the list of affected aircraft serial numbers (S/Ns) as well as inserting more restrictive criteria to determine the replacement of affected P/Ns [part numbers]. Therefore, this [ANAC] AD retains the requirements of [ANAC] EAD 2020-01-01, which is superseded, and incorporates new applicable aircraft S/Ns and new criteria for the replacement of affected P/Ns. You may examine the MCAI in the AD docket at 
                    *https://www.regulations.gov*
                     by searching for and locating Docket No. FAA-2020-1073. In the NPRM, the FAA proposed to retain the actions required by AD 2020-12-08 and proposed to require, for certain airplanes, cleaning and weighing certain mass-balances and installation or replacement, as applicable; and for certain other mass-balances for certain airplanes, replacement of those mass-balances. In the NPRM, the FAA also proposed to remove the reporting required by AD 2020-12-08. Ex Parte Contact After the comment period closed, the FAA requested clarification from Embraer about airplane delivery documentation based on a comment from NetJets. A summary of this discussion can be found in the rulemaking docket at 
                    *https://www.regulations.gov*
                     in Docket No. FAA-2020-1073. Discussion of Final Airworthiness Directive Comments The FAA received comments from Embraer and NetJets. The following presents the comments received on the NPRM and the FAA's response to each comment. Request To Add “Required for Compliance” Language Embraer requested that the FAA revise the proposed AD to add language concerning steps in the service information that are “Required for Compliance” (RC). Specifically, the commenter requested the FAA add RC language that has been used in previous ADs for Embraer products, which states that steps labeled as RC must be done to comply with the AD, while steps not labeled as RC may be deviated from using accepted methods. The commenter noted that since the proposed AD specifies complying with several steps with an Embraer service bulletin, the RC method would be useful in avoiding the need for alternative methods of compliance (AMOCs). The FAA adds the RC language requested by Embraer to ADs when the service information that is incorporated by reference in an AD contains steps with the “RC” notation. Because none of the steps in the service information incorporated by reference in this AD contain the “RC” notation, the language requested by the commenter is inapplicable. Additional information about the RC method can be found in FAA Advisory Circular (AC) No. 20-176A, 
                    *Service Bulletins Related to Airworthiness Directives and Indicating FAA Approval on Service Documents,*
                     dated June 16, 2014.[1] Request To Add Credit Service Information In the NPRM, the FAA proposed to retain the actions in paragraph (h) of the AD, which required compliance with Embraer Alert Service Bulletin SB505-55-A004, Revision 5, dated December 12, 2019 (SB505-55-A004R5). The FAA further proposed to allow credit for the actions in paragraph (h) of the AD if done previously using Embraer Alert Service Bulletin SB505-55-A004, Revision 06, dated March 25, 2020 (SB505-55-A004R06). For the new actions in paragraphs (l) through (n) of the proposed AD, the FAA proposed to require compliance with Embraer Service Bulletin SB505-55-0004, Revision 01, dated June 24, 2020 (SB505-55-0004R01). The FAA further proposed to allow credit for those actions if previously done using Embraer Service Bulletin SB505-55-0004, dated March 25, 2020. NetJets requested that the FAA revise the proposed credit paragraphs to allow credit for actions required by paragraph (h) of the proposed AD if previously done using Embraer SB505-55-A004R5 and credit for actions required by paragraphs (l) through (n) of the proposed AD if previously done Embraer SB505-55-0004R01. The FAA notes that paragraph (f) of this AD requires compliance unless already done. Thus, the AD already allows operators to take credit for the actions required by paragraphs (h), (l), (m), and (n) if done before the effective date of the AD. The commenter's requested changes are unnecessary. Request To Revise Compliance Time In the NPRM, the FAA retained certain actions and proposed new actions, with compliance times based on the age of the airplane. For the retained actions, the FAA proposed that the compliance time remain based on “the date of issuance of the original airworthiness certificate or the original export certificate of airworthiness.” For the new actions, the FAA proposed compliance times since new, with a proposed definition of “since new” as “since the date of issuance of the original airworthiness certificate or the original export certificate of airworthiness.” NetJets requested the FAA change the proposed compliance time from “within 60 months since new” to “within the next 60 months scheduled maintenance package.” The commenter stated that, upon aircraft delivery, Embraer provides a recommended date to start counting calendar inspections and that this recommended start date does not always match the date of issuance of the original airworthiness certificate or the original export certificate of airworthiness. NetJets stated it operates a large fleet of affected aircraft, and if the compliance dates in the AD do not align with the scheduled maintenance package based on Embraer's recommended state date, it could create an undue hardship, potential downtime, and lost revenue. With its comment, NetJets provided an example of an Embraer Technical Disposition (ETD) letter with a recommended start date for counting calendar inspections. The FAA has determined that the compliance times, as proposed, correspond to the compliance times in the MCAI and will ensure an acceptable level of safety. The FAA notes that the change requested by the commenter would only affect some inspections required by the AD (those that require compliance within 60 months where the term “since new” is used). Accordingly, the change requested by the commenter would result in the compliance times for some of the new inspections not aligning with the compliance times for the other new inspections or with the retained actions. The FAA has not changed this AD in this regard. However, operators may propose a change in the compliance time in 
                    ( print page 13131)
                    accordance with the AMOC procedures specified in paragraph (p) of this AD. Conclusion 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 and service information described above. The FAA reviewed the relevant data and determined that air safety and the public interest require adopting this AD as proposed. Accordingly, the FAA is issuing this AD to address the unsafe condition on these products. This AD is adopted as proposed in the NPRM. Related Service Information Under 1 CFR Part 51 The FAA reviewed Embraer Alert Service Bulletin SB505-55-A004, Revision 06, dated March 25, 2020. This service information specifies procedures for inspecting the mass-balance weights of the flight control surfaces and their respective attachment parts for corrosion and fragmentation, and performing corrective actions on certain serial-numbered Model EMB-505 airplanes. Corrective actions include installation of a stainless steel mass-balance, replacement of the mass-balance, and replacement of attachment parts. The FAA also reviewed Embraer Service Bulletin SB505-55-0004, Revision 01, dated June 24, 2020. This service information specifies procedures, for certain airplanes, for cleaning and weighing the elevator, aileron, and rudder mass-balances, and installing or replacing the mass-balances (includes replacing attachment parts), as applicable, and for certain elevator mass-balances for certain airplanes, replacing those elevator mass-balances (includes replacing attachment parts). Embraer has also issued Alert Service Bulletin SB505-55-A004, Revision 5, dated December 12, 2019, which the Director of the Federal Register approved for incorporation by reference as of July 1, 2020 (85 FR 36312, June 16, 2020). This service information 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. Other Related Service Information Embraer has also issued Embraer Service Bulletin SB505-55-0004, dated March 25, 2020. The actions specified in Embraer Service Bulletin SB505-55-0004, dated March 25, 2020, are the same as those specified in Embraer SB505-55-0004R01; however, Embraer SB505-55-0004R01 was issued to add serial-numbered airplanes to the effectivity. No additional work is required for airplanes on which Embraer Service Bulletin SB505-55-0004, dated March 25, 2020, has been accomplished. Differences Between This AD and the Service Information Embraer SB505-55-A004R5 and Embraer SB505-55-A004R06 contain procedures for inspecting for the integrity of the mass-balance weights of flight control surfaces and their attachment parts. This AD does not include that requirement. Costs of Compliance The FAA estimates that this AD affects 392 airplanes of U.S. registry.

 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 This AD will not have federalism implications under Executive Order 13132. This AD will 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 that this AD:
                    ( print page 13132) (1) Is not a “significant regulatory action” under Executive Order 12866, (2) Will not affect intrastate aviation in Alaska, and (3) Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.
