Exemption No. 10064A Regulatory Docket No. FAA-2010-0408

Captain Steve Ostrander Director, Flight Standards and Safety Allegiant Air, LLC 8360 South Durango Drive Las Vegas, NV 89113

Dear Capt. Ostranger:

This letter is to inform you that we have granted your petition to extend Exemption No. 10064. It explains the basis for our decision, describes its effect, and lists the conditions and limitations, including the date it ends.

The Basis for Our Decision

By letter dated April 2, 2012, you petitioned the Federal Aviation Adm inistration (FAA) on behalf of Allegiant Air, LLC (Allegiant Air), for an extension of Exemption No. 10064. That exemption from §§ 121.623(a) and (d), 121.643, and 121.645(e) of Title 14, Code of Federal Regulations (14 CFR) allows Allegiant Air to conduct supplemental operations within the 48 contiguous United States and the District of Columbia using the flight regulations for alternate airports as required by § 121.619 and the fuel reserve regulations as required by § 121.639 that are applicable to domestic operations.

In your petition, you indicate that there has been no change in the conditions and reasons relative to public interest and safety that were the basis for granting the original exemption.2

The FAA has determined that good cause exists for not publishing a summary of the petition

in the Federal Register because the requested extension of the exemption would not set a precedent, and any delay in acting on this petition would be detrimental to Allegiant Air.

Our Decision

The FAA has determ ined that the justification for the issuance of Exemption No. 10064 remains valid with respect to this exemption and is in the public interest. Therefore, under the authority provided by 49 U.S.C. 40113 and 44701, which the FAA Administrator has delegated to me, I grant your petition, subject to the following conditions and limitations.

Conditions and Limitations

(f) Part 121, subpart U: §§ 121.593, 121.599, 121.601, 121.607, 121.619, 121.627, 121.635, 121.637, 121.639, 121.659, and 121.663; and

2. Allegiant Air must ensure that its aircraft dispatchers hold aircraft dispatcher certificates issued under subpart C of part 65 and are properly qualified under part 121, subpart P, before permitting those persons to serve in operations conducted under this exemption.

Administrator.

The Effect of Our Decision
