Subject: Textron Aviation Inc., Model 700, Request for Partial Exemption- 25.809(a)-

Emergency Exit Arrangement 

Reference: FAA Project: TXTAV-014180 

To Whom It May Concern: 

The purpose of this letter is to transmit Textron Aviation Inc.'s request for an exemption to allow partial 

relief to 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 of the fuselage, allowing an unobstructed opening to the outside. In addition, 

each emergency exit must have means to permit viewing of the 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 of evacuee ground contact. The likely areas of evacuee ground contact must be 

viewable during all lighting conditions with the landing gear extended as well as in all conditions 

of landing gear collapse 

BACKGROUND: 

The Textron Aviation Inc. Model 700 is an executive jet with a maximum of 12 passengers and 2 

crewmembers. The overwing exit is a Type III exit. It is located on the right hand side of the cabin over 

the wing. The overwing exit has a window that provides a means to permit viewing of the conditions 

outside the exit when the exit is closed. However, from the location of the overwing exit it is not possible 

to view the likely area of evacuee ground contact with the landing gear extended as well as in all 

conditions of landing gear collapse. 

EXTENT OF RELIEF REQUEST: 

Partial relief is requested for 14 CFR 25 .809( a). Relief is requested to the requirement for a means to 

permit viewing of the likely areas of evacuee ground contact prior to opening the overwing exit.

The nature of this petition for partial exemption is similar to 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 of executive jets to compete in this market. The production of this aircraft will provide 

much needed jobs in today's environment. The added interface required to place the right hand exit in an 

area where the likely area of evacuee ground contact with the landing gear extended as well as in all 

conditions of landing gear collapse could be viewed, would limit interior arrangement of seating and 

adversely affect the customer. 

AFFECT ON SAFETY: 

In order to provide an exit that would allow viewing the likely area of evacuee ground contact with the 

landing gear extended as well as in all conditions of landing 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 of the wing or off of the wing. For the best safety of the passengers, the current location of the exit 

on the right hand side of the cabin over the wing is the best location. The current design allows the 

passengers visibility of the 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 of this exemption would not adversely affect safety of egress. 

SUMMARY FOR PUBLICATION IN FEDERAL REGISTER: 

Textron Aviation requests a partial exemption from 14 CFR 25.809(a), Amendment 116 for overwing exit 

on the Textron Aviation Inc. Model 700. 

WAIVER OF NOTICE AND PUBLIC PROCEDURE: 

Textron Aviation Inc. respectfully requests, and believes that good cause exists to justify, 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 relief requested herein is very similar to exemptions granted 

previously.
