August 20, 2015 Exemption No. 12558 Regulatory Docket No. FAA-2002-12993

Ms. Kathleen A. Yodice
Counsel Stallion 51 Corporation 411 Aviation Way, Suite 245 Frederick, MD 21701

Dear Ms. Yodice:

This letter is to inform you that we have gran ted your request for exemption. It transmits our decision, explains its basis, and gives you th e conditions and limitations of the exemption, including the date it ends.

The Basis for Our Decision

By letter dated June 18, 2015, you petitioned th e Federal Aviation Administration (FAA) on behalf of Stallion 51 Corporation (Stallion 51) , for an extension of Exemption No. 8593, as amended. That exemption from § 91.315 of Titl e 14, Code of Federal Regulations (14 CFR) allowed Stallion 51 to provide in itial and recurrent training fli ghts in its two North American TF-51 (TF-51) airplanes certificated as limited category civil aircraft.

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 pe tition would be detrimental to Stallion 51. 

## Corrected Copy2

Although you requested an extension of Exemp tion 8593, as amended, that exemption expired on July 31, 2015. Therefore, we are issuing Stallion 51 a new exemption.

The FAA has issued a grant of exemption in circ umstances similar in all material respects to those presented in your petition. In Gran t of Exemption No. 8593, as amended (copy enclosed), the FAA found that it is becoming increasingly difficult to provide initial and recurrent training in older, high performance airc raft. The FAA conclude d that an equivalent level of safety could be met by the petitione r’s use of approved flight and maintenance manuals, as well as following the conditions and limitations stated in this exemption.

Having reviewed your reasons for re questing an exemption, I find that—

 they are similar in all material respects to relief previously granted in Exemption No. 8593, as amended;

 the reasons stated by the FAA for granting th e enclosed exemption also apply to the situation you present; and

 a grant of exemption is in the public interest.

Our Decision

The FAA updates and modifies conditions and limitations of its exemptions as they are
issued. The conditions and limitations of Exemption No. 8593, as amended, have been updated for consistency with similarly issued ex emptions in light of recent safety concerns.

The FAA has modified and supplemented the co nditions and limitations of Exemption No. 8593, as amended, to better define the intent and add additional oversight . Please note that the
conditions and limitations includ ed with an exemption are no t based on specific regulations but are the FAA’s means of ensuring an equi valent level of safety. This necessitates limitations that go beyond the established regu lations due to the f act that the proposed operation is, by its need for an exemption, outsi de the normal regulatory structure. These new
conditions and limitations match those contained in grants of exemption issued to similarly situated organizations.

Condition and Limitation No. 1 was added to desc ribe the aircraft covered by this exemption.

Condition and Limitation No. 2(b) in Exemption No. 8593, as amended, was removed to match those contained in subsequent grants of exemption issued to similarly situated organizations.

Condition and Limitation Nos. 2 and 3 were added to define the activity permitted under this exemption, and to define requirements for persons receiving flight instru ction in the aircraft
identified in Condition and Limitation No. 1. In your petition, you state that “[o]rientation flights are offered to [...] even individuals w ho are currently student pilots, or may become student pilots in the future.” Under the terms of this exemption, Stallion 51 may only offer flights for the purpose of recurrent pilot training or proficiency to persons who hold at least a3

private pilot certificate with a single engine land rating. Th is exemption does not permit
Stallion 51 to conduct orientation rides or training flights for those persons who do not hold at least a private pilot certificate. This limitation is consistent with the FAA’s findings in Exemption No. 10205, as amended, which establishe d that persons receiv ing flight training under that exemption must hold at least a privat e pilot certificate with applicable category and class ratings.

The training syllabus and chief instructor requi rements identified in Condition and Limitation
Nos. 4 and 5 will allow the FAA to be aware of the scope of the training activity under the exemption, and will add some assurances regarding the qualifications of the chief instructor employed by Stallion 51.

Condition and Limitation No. 6, which is Condi tion and Limitation No. 1 in Exemption 8593, as amended, has been amended to emphasize specific 14 CFR requirements that apply to the aircraft and operation.

Condition and Limitation No. 7, which is Condi tion and Limitation No. 2 in Exemption 8593, as amended, has been amended to include a minimum total of 1,500 hours of aeronautical flight experience, including 25 hours as pilot-in-com mand in the aircraft make and model; 25 takeoffs and 25 landings in any variant of P-51 or TF-51 airplane. This amendment is necessary to meet recent safety concerns and for consistency with similarly granted exemptions.

Condition and Limitation No. 8 was added to requ ire Stallion 51 to inform persons receiving flight instruction under this exemption that its ai rcraft hold a limited airw orthiness certificate, the significance of the limited airworthine ss certificate as comp ared to a standard airworthiness certificate, and that the FAA has authorized this flight under a grant of exemption from the requirements of § 91.315.

Condition and Limitation No. 9 was added to requ ire Stallion 51 to notify the jurisdictional Flight Standards District Office (FSDO) by written report, electronic mail, or facsimile, of certain occurrences of damage, failu re, or malfunction within 24 hours.

Condition and Limitation No. 10 has been added to increase operational safety by specifying minimum flight visibility.

Condition and Limitation No. 11 has been added to ensure that only a flight instructor and a trainee are permitted aboard the aircraft during flight operations.

Condition and Limitation No. 12 has been added to ensure that Stallion 51 aircraft have the equipment listed in §§ 91.205 (a s applicable to the operation being conducted) and 91.207 and that the equipment must be in an operable condition dur ing the flight.

The FAA has determined that the justificati on for the issuance of Exemption No. 8593, as amended, remains valid with respect to this exemption and is in the public interest.4

Therefore, under the authority provided by 49 U.S.C. 106(f), 40113 and 44701, which the FAA Administrator has delegate d to me, I grant Stallion 51 Co rporation (Stallion 51) an exemption from 14 CFR § 91.315 to the extent ne cessary to allow St allion 51 to provide initial and recurrent training flights in its two North American TF -51 (TF-51) airplanes certificated as limited category ci vil aircraft, subject to the co nditions and limitations below.
