Re: Exemption No. 4317, as amended; Docket No. FAA

- 2001

- 9096

Ladies/Gentlemen:

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

Transport Association of America, Inc. (ATA), on behalf of its member airlines 1 petitions the

Administrator for an extension of Exemption No. 4317 L (Docket No. FAA

- 2001

- 9096). This

exemption is sc he duled to expire on April 30, 2011

. The relief granted by Exemption 4317 has

been in effect continuously since March 26, 1980, with the exception of a brief, unintended

hiatus in 1984. See Exemption Nos. 2945, 2945A, and 4317

. Exemption 4317 construes 14 CFR

§ 121.485(b) to apply only when a three

- pilot crew is required by regulation. U.S. air carriers

have operated on this basis since § 121.485 was promulgated in 1945. U.S. air carriers

understood this to be the meaning of this provision when it was promu lgated in 1945, and

Exemption 4317 confirms this construction. Granting this request is in the public i nterest because

it will maintain consistent implementation of the FARs. Any changes to Exemption 4317 would

create considerable confusion about implementing 14 CFR 121.485, and would have a

significant adverse economic impact on U.S. air carriers and ultimately, the public. All facts,

conditions and circumstances as permitted in the original exemption should remain in force.

This e xemption will not adversely a ffect s afety

. U.S. airlines have operated safely under 14 CFR

121.485 as construed by Exemption 4317, since that provision was first promulgated more than

50 years ag o

. It is fully recognized that if a flight is scheduled in excess of 12 hours, the operator

is required to have three pilots and an additional crewmember and the rest provision s of 14 CFR

121.485 would apply. The circumstances justifying the issuance of Exemption 4317 have not

changed, and this petition merely requests the continuation of Exemption 4317. This petition

does not seek to change the conditions or limitations of the cu rrent exemption. The renewal of

this exemption is not a controversial issue. For this reason, and the reasons stated in prior

applications , ATA requests that a finding of good cause be made for waiving publication in the

Federal Register , (14 CFR §11.87). Granting the req uested relief will not set a precedent. The

existence of the exemption is well known and widely accepted.

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

Very truly yours,
