 Exemption No.10977

 Regulatory Docket No. FAA-2009-1034

Ms. Sheryl Carlucci

Executive Director

North Bay Air Museum, Inc.

23982 Arnold Drive

Sonoma, CA 95476

Dear Ms. Carlucci:

This letter is to inform you that we have granted your request for exemption. It transmits our 

decision, explains its basis, and gives you the conditions and limitations of the exemption, 

including the date it ends.

The Basis for Our Decision

By letter dated December 26, 2013, you petitioned the Federal Aviation Administration 

(FAA) on behalf of the North Bay Air Museum, Inc. (NBAM), for an extension of 

Exemption No. 9996. That exemption from §§ 91.315, 119.5(g), and 119.21(a) of 

Title 14, Code of Federal Regulations (14 CFR) allows NBAM to conduct historical 

flight experience operations in its North American F-51 (F-51) and Curtis P-40 (P-40). 

Exemption No. 9996 expired on January 31, 2014. Therefore, we will treat your request 

as a new petition.

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 exemption would not set a precedent, 

and any delay in acting on this petition would be detrimental to NBAM.
2

The FAA has issued a grant of exemption in circumstances similar in all material respects to 

those presented in your petition. In Grant of Exemption No. 9996, the FAA found that 

preserving historic U.S. aircraft is in the public interest, in the same manner that preserving 

historic buildings, landmarks, and neighborhoods has been determined to be in the public 

interest. While the aviation history can be represented with static displays in museums in the 

same manner that historic landmarks can be represented in museums, the public has shown a 

willingness to support the preservation and operation of historic aircraft and a desire to 

experience flights in them.

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

• they are similar in all material respects to relief previously requested in the enclosed 

Grant of Exemption No. 9996;

• the reasons stated by the FAA for granting Exemption No. 9996 also apply to the

situation you present; and

• a grant of exemption is in the public interest.

Our Decision

The conditions and limitations of this exemption differ from those of Exemption No. 9996. 

First, detail was added to the specific aircraft references, namely by version and serial 

number. Second, detail was also added to the applicable operational and maintenance 

documentation for both aircraft. These changes are to provide consistency of the safetyrelated aspects of the conditions and limitations. The FAA will be making these changes to 

all living history flight experience (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.

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

respective serial numbers. 

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

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

References to the applicable Type Certificate Data Sheets (TCDS) for both aircraft were 

also added.

Limitation 4 was split into two separate limitations (limitations 4 and 5) to ensure a better 

understanding of the intent. Subsequent limitations were renumbered. 
3

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

arises between the limitations in the applicable technical guidance and the FAA-issued operating 

limitations.

Under the authority contained in 49 U.S.C. §§ 106(f), 40113, and 44701, which the FAA

Administrator has delegated to me, I hereby grant North Bay Air Museum, Inc. (NBAM) an 

exemption from 14 CFR §§ 91.315, 119.5(g), and 119.21(a) to conduct historical flight

flight, which will avoid densely populated areas or congested airways in 
10

accordance with 14 CFR § 91.319(c) for aircraft certificated in the experimental 

category. Those operators utilizing aircraft certificated in the limited category 

are not bound by the restriction regarding the avoidance of densely populated 

areas or congested airways;

f. For passenger-carrying flights greater than 25 statute miles from the departure 

airport and up to 50 statute miles, the PIC must obtain weather reports and 

forecasts prior to flight and valid for the duration of the proposed operation that 

indicate that the weather would be no less than 5 statute miles visibility and 

cloud ceilings no less than 2,000 feet AGL. Passenger-carrying operations shall 

be terminated if ceiling and visibility become less than the minimum required 

by these conditions and limitations. Weather forecasts listing discriminators 

such as probability (PROB), becoming (BECOMG) or temporarily (TEMPO) 

shall be limiting; and

g. The airplane may only be operated from an airport that has a fire station or 

fire-fighting services available or within close proximity of the airport.
