Subject: Textron Aviation Inc., Model 700, Request for Partial Exemption- 25.809(a)- EmergencyExitArrangement Reference: FAA Project: TXTAV-014180

To Whom It May Concern: The purpose ofthis letter is to transmit Textron Aviation Inc.'s request for an exemption to allow partial reliefto 14 CFR 25.809(a), Amendment 116, for the Model 700 Citation Longitude. Regulation 14 CFR 25.809(a), Amendment 116 reads as follows: (a) Each emergency exit, including each flightcrew emergency exit, must be a movable door or hatch in the external walls ofthe fuselage, allowing an unobstructed opening to the outside. In addition, each emergency exit must have means to permit viewing ofthe conditions outside the exit when the exit is closed. The viewing means may be on or adjacent to the exit provided no obstructions exist between the exit and the viewing means. Means must also be provided to permit viewing of the likely areas ofevacuee ground contact. The likely areas ofevacuee ground contact must be viewable during all lighting conditions with the landing gear extended as well as in all conditions oflanding gear collapse 

### BACKGROUND: The Textron Aviation Inc. Model 700 is an executivejetwith a maximum of 12 passengers and 2 crewmembers. The overwing exit is a Type III exit. It is located on the right hand side ofthe cabin over the wing. The overwing exit has a window that provides a means to permit viewing ofthe conditions outside the exit when the exit is closed. However, from the location ofthe overwing exit it is notpossible to view the likely area ofevacuee ground contactwith the landing gear extended as well as in all conditions oflanding gear collapse. 

### EXTENT OF RELIEF REQUEST: Partial reliefis requested for 14 CFR25.809(a). Reliefis requested to the requirement for a means to permit viewing ofthe likely areas ofevacuee ground contact prior to opening the overwing exit.16-1053 Page 2 of 2 The nature ofthis petition for partial exemption is similarto the previously granted Exemption 10756 for the Learjet Model LJ200, Exemption 10757 for the Embraer Model EMB-550, and Exemption 11350 for the Textron Aviation Inc. Model 680A. 

### PUBLIC INTEREST: Textron Aviation Inc. competes in the global market. This aircraft is a needed expansion to the Textron Aviation line ofexecutivejetsto compete in this market. The production ofthis aircraft will provide much neededjobs in today's environment. The added interface required to place the right hand exit in an area where the likely area ofevacuee ground contactwith the landing gear extended as well as in all conditions oflanding gear collapse could be viewed, would limit interior arrangement ofseating and adversely affectthe customer. 

### AFFECT ON SAFETY: In order to provide an exitthat would allow viewing the likely area ofevacuee ground contact with the landing gear extended as well as in all conditions oflanding gear collapse, the exit would need to be moved forward in the cabin. This would mean that the exit would either be located on the very leading edge ofthe wing or offofthe wing. Forthe best safety ofthe passengers, the current location ofthe exit on the right hand side ofthe cabin overthe wing is the best location. The current design allows the passengers visibility ofthe area outside the overwing exit, to assess the immediate danger. Once out of the aircraft, on the wing, the passenger can view in all directions, assessing the best route to leave the wing. Thus the granting ofthis exemption would not adversely affect safety ofegress. 

### SUMMARY FORPUBLICATION INFEDERAL REGISTER: Textron Aviation requests a partial exemption from 14 CFR 25.809(a), Amendment 116 for overwing exit onthe Textron Aviation Inc. Model 700. 

### WAIVER OF NOTICE AND PUBLIC PROCEDURE: Textron Aviation Inc. respectfully requests, and believes that good cause exists tojustify, that action on this petition not be delayed by publication and comment procedures. Textron Aviation Inc. feels this request does not set a precedent because the reliefrequested herein is very similarto exemptions granted previously.
