 Exemption No. 11771A 

 Regulatory Docket No. FAA-2015-0058 

Mr. Loren Crea 

Director of Flight Operations 

Neptune Aviation Services Inc. 

2 Corporate Way 

Missoula, MT 59808 

Dear Mr. Crea: 

This letter is to inform you that we have granted your petition to extend and amend 

Exemption No. 11771. 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 2, 2015, you petitioned the Federal Aviation Administration (FAA) 

on behalf of Neptune Aviation Services, Inc. (Neptune) for an extension of, and amendment 

to, Exemption No. 11771. That exemption from § 91.611 of Title 14, Code of Federal 

Regulations (14 CFR) allows Neptune to conduct ferry flights with one engine inoperative on 

its BAe 146-200A aircraft to one of Neptune’s maintenance facilities without obtaining a 

special flight permit (SFP) for each flight. 

The amendment you request would allow Neptune to fly its BAe 146-200A aircraft that do 

not meet applicable airworthiness requirements, but is capable of safe flight, to a base where 

repairs are to be performed, without obtaining a SFP for each flight. 

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. 

A summary of the petition was published in the Federal Register on January 12, 2016 (81 FR 

1468). No comments were received.

In your original petition for exemption, you asked for the relief necessary to permit Neptune 

to ferry a BAe-146 airplane with one engine inoperative to a maintenance facility, without 

obtaining a SFP for each flight. Because § 91.203 specifically allows flights under § 91.611, 

we determined that relief from § 21.197 was not necessary. Your request for amendment 

clarified that you also wanted relief to conduct ferry flights for other maintenance purposes. 

Neptune supports its request with the following information concerning an equivalent level of 

safety: 

While Neptune Aviation is operating under Part 91 for the majority of our flight time, 

and then under Part 137 while in the fire control area, the company has chosen to 

mimic much of Part 121 and 135 Air Carrier regulatory requirements. We enhance 

safety and streamline flight and maintenance operations through company policy that 

have established the following items: 

1. Operate a 24/7 Maintenance Control Center (MCC) to manage the fleet needs while 

deployed on contract. 

2. A comprehensive maintenance Required Item Inspection (RII) program has been 

developed and implemented for both the P2V and BAe-146 fleets. 

3. Neptune Aviation has a Safety Management System (SMS) program in place. 

4. Flight and maintenance personnel receive annual and specialized training. 

5. Instituted a Deferred Maintenance Item (DMI) Program and a formal Functional 

Check Flight (FCF) program for post-maintenance events, i.e., heavy checks, annual 

inspections, modification, etc. 

6. The company operates two Part 145 Certificated Repair Stations (Missoula, MT and 

Alamogordo, NM) to support the fleet while deployed and to perform annual 

inspections and maintenance checks. 

Additional factors with a positive impact on safety include: 

 Neptune’s airplanes were originally type certificated as transport category airplanes, 

the most stringent airworthiness standard for airplanes. 

 The BAe-146s are powered by four turbofan engines. 

 Neptune’s implementation of air carrier like operations and maintenance procedures. 

 Oversight provided by the Helena Flight Standards District Office (FSDO) 

Considering the foregoing, along with the conditions and limitations placed in this exemption, 

the FAA finds that an equivalent level of safety, as provided by the rule, will be met by this 

exemption.

Our Decision 

The FAA has determined that the justification for the issuance of Exemption No. 11771 

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 Neptune Aviation Services, Inc. (Neptune) an exemption from 

14 CFR §§ 21.197 and 91.611 to apply for and be issued an authorization for ferry flight with 

one engine inoperative and a special flight permit with a continuing authorization without 

holding an air carrier or an operating certificate, subject to the conditions and limitations

FSDO of any changes in these management personnel or BAe-146 fleet policies and
