Background The FAA issued a notice of proposed rulemaking NPRM to amend 14 CFR
part 39 by adding an AD that would apply to all Embraer S.A. Model EMB
500 and EMB505 airplanes with certain engines installed. The NPRM
published in the Federal Register on August 2, 2021 86 FR 41410. The NPRM was prompted by MCAI
originated by the Agencia Nacional de Aviacao Civil ANAC, which is the aviation authority for Brazil. ANAC
issued AD 20200503, effective June 1, 2020 ANAC AD 20200503 also referred to after this as the MCAI, to correct an unsafe condition on Embraer S.A. Model EMB500 and EMB505
airplanes with certain engines installed.
Although the affected airplanes were designed for operation at temperatures below 54 C, the operational envelope in the AFM does not contain the necessary limitations and procedures to operate safely in these colder temperatures. The MCAI states that operation of the affected airplanes at static air temperatures below 54 C
without these limitations could cause several systems and components to operate inadequately, resulting in multiple systems failures.
Accordingly, the MCAI requires updating the AFM to incorporate a modified operational envelope that establishes restrictions and minimum airspeed required for each static temperature range. In the NPRM, the FAA proposed to require revising the AFM to incorporate the new and revised airspeed limitations and procedures specified in the manufacturers service information. The FAA is issuing this AD
to prevent inadequate operation below the allowable temperature, which could result in multiple systems failures and compromise safe flight of the airplane.

1077.
Discussion of Final Airworthiness Directive Comments The FAA received a comment on the NPRM from Embraer. The following presents the comment received and the FAAs response to the comment.
Embraer requested that the FAA
change the final rule to allow operators

to revise the AFM using EMB500 AFM
2656, Revision 24, dated March 17, 2020, and EMB505 AFM2665, Revision 21, dated March 13, 2020, as well as future FAA-approved AFM
revisions. Embraer stated that the information in the service information proposed for incorporation by reference has been included in the March 2020
AFM revisions for each model type.
The FAA agrees and has revised the AD to allow use of a different document provided the language is identical to the language in the service information incorporated by reference.
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 FAAs 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
reviewed the relevant data, considered the comment received, and determined that air safety requires adopting this AD
as proposed. Accordingly, the FAA is issuing this AD to address the unsafe condition on these products. Except for the changes described previously, this AD is adopted as proposed in the NPRM. None of the changes will increase the economic burden on any operator.
Related Service Information Under 1
CFR Part 51
The FAA reviewed Embraer Phenom Operational Bulletin No. 500001/20, dated March 9, 2020; and Operational Bulletin No. 505005/13, Revision 1, dated March 9, 2020. This service information specifies revising the AFM
to incorporate limitations and procedures for the minimum airspeed in the affected region of the operational envelope. These documents are distinct since they apply to different airplane models. 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.
Costs of Compliance The FAA estimates that this AD
affects 590 airplanes of U.S. registry.
