FAAs 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 FAAs bilateral agreement with the State of Design Authority, it has notified the FAA of the unsafe condition described in the MCAI and service information

referenced above. The FAA is issuing this NPRM after determining the unsafe condition described previously is likely to exist or develop on other products of the same type design.
Proposed AD Requirements in This NPRM
This proposed AD would require revising the AFM by accomplishing the actions specified in the service information already described.
Costs of Compliance The FAA estimates that this AD, if adopted as proposed, would affect 590
airplanes of U.S. registry. The FAA
estimates the following costs to comply with this proposed AD:

Authority for This Rulemaking Title 49 of the United States Code specifies the FAAs 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 Agencys 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,
VerDate Sep<11>2014

Jkt 253001

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.

c Applicability This AD applies to Embraer S.A. Models EMB500 and EMB505 airplanes, all serial numbers, certificated in any category, with Model PW617FE or PW617F1E engines for Model EMB500 airplanes or Model PW535E engines for Model EMB505
airplanes installed.

e Unsafe Condition This AD was prompted by a report that the operational envelope does not contain airspeed limitations and procedures for operating the airplane at static air temperatures below 54 C. The FAA is issuing this AD to prevent inadequate operation below the allowable temperature.
The unsafe condition, if not addressed, could result in multiple systems failures and compromise safe flight of the airplane.
