 Exemption No. 10092C 

 Regulatory Docket No. FAA-2010-0392 

June 11, 2014 

Mr. John T. Sessions 

Chief Executive Officer 

Historic Flight Foundation 

10719 Bernie Webber Drive 

Mukilteo, WA 98275-5011 

Dear Mr. Sessions: 

This letter is to inform you that we have granted your request to extend Exemption No. 10092B. 

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

The Basis for Our Decision 

By letter dated February 27, 2014, you petitioned the Federal Aviation Administration (FAA) on 

behalf of Historic Flight Foundation (HFF) for an extension to Exemption No. 10092B. That 

exemption from §§ 91.319(a)(2), 119.5(g), and 119.21(a) of Title 14, Code of Federal 

Regulations (14 CFR) allows HFF to operate a North American B-25D (N88972) for the purpose 

of carrying passengers on local educational and historical flights for compensation or hire.

A review of your petition appears to 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 HFF. 

Our Decision 

The FAA has modified the conditions and limitations of Exemption No. 10092B as follows: 

 Limitation 1 was changed by adding the references to the version of the aircraft and the 

applicable serial number. 
AFS-14-181-E 

 Limitation 2 was changed to include more detailed references to the applicable civil and 

military operational, maintenance, and inspection guidance applicable to the aircraft. 

 A note was added to Limitation 5 and Limitation 6 to provide for a process should any 

conflict arise between the limitations in the applicable technical guidance and the FAAissued operating limitations. 

 Limitation 6 Required Training Tasks table, tasks (c) (ii) and (d) (iii) as previously 

drafted may lead the reader to the incorrect impression that an actual shutdown of a 

powerplant was required. This clarification is necessary since the term “simulated 

powerplant failure” was used in task (e) (ii) Landings and Approaches to Landings. 

However, tasks (c) (ii) and (d) (iii) did not use the word “simulated.” The wording is 

revised to clarify that the actual shutdown (and re-start) of a powerplant should only be 

demonstrated in task (d) (iii) Inflight Maneuvers, as specified. The revision also 

stipulates that an actual shutdown and re-start of a powerplant is only required for initial 

PIC qualification. 

These changes are to provide consistency of the safety-related aspects of the conditions and 

limitations. The FAA will be making these changes to all LHFE exemptions as they are 

amended or extended. Please note that the conditions and limitations included with an 

exemption are not based on specific regulations but are the FAA’s means of ensuring an 

equivalent level of safety. This may necessitate limitations that go beyond the established 

regulations due to the fact that the proposed operation is, by its need for an exemption, outside 

the normal regulatory structure. In addition, the FAA may, when necessary, revise the 

conditions and limitations or require corrective action in order to adequately mitigate safety 

concerns and risk factors as they become known. 

The FAA has also amended the exemption to add a regulation to the list of applicable regulations 

subject to relief provided by this exemption. Although the petitioner has requested relief from 14 

CFR §§ 91.319 (a) (2), 119.5(g), and 119.21(a) to operate certain aircraft for the purpose of 

carrying passengers for compensation or hire on LHFE flights, the FAA has determined that 

certain conditions and limitations may preclude HHF from conducting operations pursuant to this 

exemption. Those conditions and limitations are prescribed as part of the special airworthiness 

certificate issued for experimental or limited category aircraft. Adherence to those conditions 

and limitations is required by pertinent parts of § 91.9(a) which prescribe that: 

 

“No person may operate a civil aircraft without complying with the operating limitations 

specified in the approved Airplane or Rotorcraft Flight Manual, markings, and placards, or as 

otherwise prescribed by the certificating authority of the country of registry.” 

Generally, the FAA issues a limitation that states that no person may operate the aircraft carrying 

persons or property for compensation or hire (see Operating Limitation Experimental Exhibition 

Aircraft, B-25D, N88972, Serial No. 43-3318, # 12). This one limitation issued with the 

airworthiness certificate is the only limitation which the exemption from §91.9 is applied to. 
AFS-14-181-E 

Therefore, the FAA finds that it is appropriate to exempt HHF from § 91.9(a) to the extent 

necessary to conduct operations pursuant to this exemption. 

The FAA has determined that the justification for the issuance of Exemption No. 10092, as 

amended, remains valid 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 

HFF relief from sections §§ 91.9(a), 91.319(a)(2), 119.5(g), and 119.21(a) of Title 14, Code of 

Federal Regulations (14 CFR) to operate a North American B-25D (N88972) for the purpose of 

carrying passengers on local educational and historical flights for compensation or hire, subject
