 Exemption No. 10798A

 Regulatory Docket No. FAA-2011-0269

Mr. Christian M. Toro

Director of Quality/Chief Inspector

Allegiant Travel Company

1201 N. Towncenter Drive

Las Vegas, NV 89144

Dear Mr. Toro:

This letter is to inform you that we have granted your petition to extend Exemption No. 

10798. It explains the basis for our decision, describes its effect, and lists the conditions and 

limitations.

The Basis for Our Decision

By letter dated May 21, 2015, you petitioned the Federal Aviation Administration (FAA) on 

behalf of Allegiant Travel Company (Allegiant) for an extension of Exemption No. 10798. 

That exemption from §§ 91.203(a) and (b) and 121.153(a)(1) of Title 14, Code of Federal 

Regulations (14 CFR) allows Allegiant to operate its aircraft on a temporary basis following 

the incidental loss or mutilation of a certificate of airworthiness, aircraft registration 

certificate, or both.

In your petition, you indicate similar conditions and reasons relative to public interest and 

safety that were the basis for granting the original exemption.

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.

Our Decision

The FAA has determined that the justification for the issuance of Exemption No. 10798

remains valid with respect to this exemption and is in the public interest. Therefore, under the 

authority provided by 49 U.S.C. 106(f), 40113 and 44701, which the FAA Administrator has 

delegated to me, I hereby grant Allegiant Air, LLC an exemption from 14 CFR §§ 91.203(a) 

and (b) and 121.153(a)(1) of Title 14, Code of Federal Regulations (14 CFR) to allow

Allegiant to operate its U.S.-registered aircraft in domestic operations temporarily following 

the incidental loss or mutilation of that aircraft’s airworthiness certificate, registration 

certificate, or both, subject to the following conditions and limitations.

Conditions and Limitations 

1. Allegiant must apply for and receive from the FAA Flight Standards District 

Office (FSDO) responsible for its air carrier certificate an amendment to its 

operations specifications authorizing it to exercise the privileges of this exemption.

2. Allegiant must develop a comprehensive program that ensures: 

a. An appropriate entry in the aircraft logbook for continued operation of its 

aircraft when the airworthiness certificate or registration certificate is lost, 

stolen, or mutilated; 

b. Timely application is made to the FAA for a replacement certificate; and 

c. A replacement certificate from the FAA is installed on the affected aircraft. 

This program must be FAA-approved, and instructions for its use shall be included 

in Allegiant’s air carrier manual as required by 14 CFR § 135.21.

3. The program specified in Condition/Limitation No. 2(a) must contain:

a. A requirement that the following statement be entered into the appropriate 

section of the aircraft logbook whenever this exemption is to be utilized: 

“This aircraft is being operated without a certificate of [registration, 

airworthiness] under the provisions of Exemption No. 10798 for a 

period of 3 working days, not including weekends or Federal holidays, 

following the start of the next business day, beginning: 

TIME: _____ DATE:_____ 20__”

The signature, title, and station location of the person(s) authorized by 

Condition/Limitation No. 3(b) shall be affixed to this statement;

b. Identification of the designated person(s) by name, including job titles and 

responsibilities within Allegiant’s maintenance organization authorized to 

enter the statement outlined in Condition/Limitation No. 3(a) and the method 
3

or methods wherein the documents required under Condition/Limitation No. 5 

will be transmitted to the affected aircraft;

c. An arrangement whereby those persons within the organization responsible for 

Allegiant’s certificates of registration and airworthiness will maintain a current 

record of the data from the certificates of each aircraft within its fleet which 

may be affected by this exemption. This data must be made readily available to 

those persons identified in Condition/Limitation No. 3(b) and must be kept 

current at all times;

d. Procedures to ensure that the FAA principal maintenance inspector with 

responsibility for Allegiant would be immediately notified of a missing or 

mutilated certificate and that timely application is made to the FAA for a 

replacement certificate (in the case of an airworthiness certificate) or a 

duplicate certificate (in the case of a registration certificate).

4. The privileges of this exemption may only be exercised by Allegiant for temporary 

replacement of a missing or mutilated certificate that is current and in effect and 

applies to U.S.-registered aircraft listed in Allegiant’s FAA-approved operations 

specifications.

5. A copy of the grant of exemption and a copy of the operations specifications 

authorizing its use must be carried on board the aircraft when exercising the 

privileges of the exemption.

6. The privileges of the exemption may only be exercised when the affected flight is 

operated totally within the contiguous 48 States of the United States, including the 

District of Columbia. 

The Effect of Our Decision

This exemption terminates on June 30, 2017, unless sooner superseded or rescinded.

Sincerely,

/s/

John S. Duncan

Director, Flight Standards Service
