 Exemption No. 10588A 

 Regulatory Docket No. FAA-2012-0406 

Mr. Bill Fischer 

Executive Director 

EAA Warbirds of America 

3000 Poberezny Road 

Oshkosh, WI 54903-3086 

Dear Mr. Fischer: 

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

10588. It explains the basis for our decision, describes its effect, and lists the conditions and 

limitations. 

The Basis for Our Decision 

By letter dated March 10, 2014, you petitioned the Federal Aviation Administration (FAA) 

on behalf of EAA Warbirds of America (EAA) for an extension of Exemption No.10588. 

That exemption from § 91.531(a)(1) of Title 14, Code of Federal Regulations (14 CFR) 

allows EAA to operate large airplanes that possess experimental certificates for the purpose of 

exhibition which have been designed with only one pilot station, to be operate without a pilot 

who is designated as second in command (SIC) of that airplane. 

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. 

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 EAA.

Our Decision 

The FAA has determined that the justification for the issuance of Exemption No. 10588, 

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 grant the Experimental Aircraft Association Warbirds of America relief 

from 14 CPR§ 91.531(a)(l) to the extent necessary to allow its members to operate large 

airplanes, that possess experimental certificates for the purpose of exhibition, without a 

pilot who is designated as second in command provided those aircraft: (1) were originally 

designed with only one pilot station; or (2) were originally designed with more than one pilot 

station (or a single pilot station and a required flight crewmember station) and were 

authorized by an armed force that operated the aircraft to be operated with only one pilot and 

no additional flight crewmember. This exemption is subject to the following conditions and 

limitations. 

Conditions and Limitations 

1. EAA WOA must maintain a current list of owners and operators conducting operations 

under the provisions of this exemption. The list must include the owner/operator’s 

name and address and the manufacturer, model, serial number, and registration number 

of the airplane being operated. This list must be made available to the FAA upon 

request. 

2. When exercising the privileges of this exemption, the pilot of the airplane must have in 

his or her personal possession documentation indicating that he or she is currently a 

member of EAA WOA. This documentation must be presented when requested by a 

representative of the Administrator. 

3. A copy of this exemption must be carried aboard any airplane operated under the 

provisions of this exemption when such operations are conducted. 

4. The operating limitations for the airplane must not require a second flight crewmember. 

5. The pilot in command must have demonstrated proficiency to operate the aircraft as a 

single pilot. 

6. The airplane must not be in a configuration for which a second flight crewmember 

was required by an armed force that operated the aircraft. 

7. Any operational limitations specified by the airplane’s manufacturer or imposed by an 

armed force to permit the operation of these airplanes with a single flight crewmember 

(e.g. military technical order) must be complied with. 

8. This exemption does not provide relief from compliance with the provisions of any 

operating limitation issued pursuant to the provisions of 14 CFR § 91.319.

The Effect of Our Decision 

This exemption terminates on July 31, 2016, unless sooner superseded or rescinded. 

Sincerely, 

/s/ 

John S. Duncan 

Director, Flight Standards Service
