Dear Mr. Hollerbach: Transport Airplane Directorate 1601 Lind Ave , SW. Renton ,Washington 98057-3356

Exemption No. 10557A Regulatory Docket No. FAA-2011-1240

This letter is to inform you that we have amended exemption no
. I0557. lt explains the basis for our decision and describes its effect. 

### The Basis for Our Decision By letter GCF-0333/2015 dated March 24, 2015, you petitioned the Federal Aviation Administration (FAA), on behalfofEmbraer, for an amendment to exemption no. 10557. That exemption, from§ 25.791(a) ofTitle 14, Code ofFederal Regulations, provides relieffrom the requirements ofpassenger information signs and placards. Your recent petition for an amended exemption requests adding Embraer Model EMB545 airplanes to the original exemption. The FAA notes that the Embraer Model EMB545 airplane is a derivative ofthe Model EMB-550 airplane. These airplanes are configured as businessjets intended for private use, and which are not for hire, not for common carnage. Your petition includes no request for substantive change in the conditions, and reasons relative to public interest and safety, that were the basis for granting the original exemption. Embraerrequests that this amendment apply to future similarly non-compliant derivatives ofthe current Embraer EMB-550 airplane (including, but not limited to, EMB-545). The FAA grants exemptions only to defined airplane-model designs. Likewise, the FAA must evaluate each airplane model to determine ifthe exemption is appropriate for the design ofa given airplane model. The only currently defined Model EMB-550 derivate airplane is the Model EMB-545 airplane. Therefore, this amendment addresses only the Embraer Model EMB-545 airplane as a derivative ofthe Model EMB-550 airplane.2



### FederalRegister 

### Publication The FAA has determined that good cause exists for not publishing a summary ofthe petition in the Federal Register for public comment because the requested amendment to the exemption would not set a precedent, and any delay in acting on this petition would be detrimental to Embraer EMB-545 delivery schedules. 

### Our Decision The FAA has determined that thejustification for the issuance ofexemption no. I0557 remains valid with respect to this amendment and is in the public interest. As Embraer notes, in pertinent part, in their amendmentpetition: Embraer has analyzed Exemption I0557 and this was also considered applicable to similarly non-compliant derivatives ofthe current Embraer Model EMB-550 airplane (including, but not limited to EMB-545) once the same interior design, all the arguments and compensating factors are considered the same. 

### The Effect ofOur Decision Underthe authority provided by 49 U.S.C. 40113 and 44701 , which the FAA Administrator has delegated to me, I grant Embraer an amendment to exemption no. 10557 to include the Embraer Model EMB-545 airplane. All other conditions and limitations ofexemption no. 10557 remain the same. This letter must be attached to, and is a part of , exemption no. 10557. Sincerely,

Michael Kaszycki Acting Manager, Transport Airplane Directorate Aircraft Certification Service
