Re: Exemption No. 3585, As Amended; Docket No. FAA-2001-9379 

Ladies/Gentlemen: 

In accordance with Title 14 of the Code of Federal Regulations (14 CFR) § 11.61, the 

Airlines For America, Inc. (A4A), on behalf of its member airlines1 petitions the 

Administrator for an extension of Exemption No. 3585T (Docket No. FAA-2001-9379). 

This exemption is scheduled to expire on May 31, 2017. 

Exemption 3585 provides relief, under certain conditions and limitations, from 14 CFR §§ 

121.613, 121.619(a), and 121.625 to the extent necessary to: (1) dispatch an airplane, under 

IFR, to a destination airport; and (2) list an alternate airport for that destination airport when 

the Aerodrome Forecast (TAF) for either one or both of those airports indicates by the use of 

conditional language such as "BECMG," "PROB," or "TEMPO," in the TAF that the 

weather could be below authorized weather minimums at the time of arrival. Dispatch 

under these circumstances is permitted if the information contained in the main body of the 

T AF used by the certificate holder's dispatch center shows, for each flight to be dispatched, 

that the weather at the destination airport and alternate airport listed in the dispatch release 

will be at or above authorized weather minimums at the time of arrival. 

This exemption has been used to the benefit of the traveling public for more than twenty 

two years, with no known compromise of safety. With regard to public interest and 

equivalent levels of safety, the circumstances that warranted the initial grant of 

exemption continue to exist.

The renewal of this exemption is not a controversial issue. For this reason, and the reasons 

stated above, A4A requests that a finding of good cause be made for waiving publication in 

the Federal Register. Granting the requested relief will set no precedents. The existence of 

the exemption is well known and widely accepted. 

A summary ofthis petition as required by 14 CFR § 11.81 is attached. 

If you have any questions or need additional information, please call me at (202) 626-

4031. 

Very truly yours, f)
