RE: Request for Extension of Exemption No. 10108

Docket No. FAA-2010-0727

Pursuant to §11.61(b) of Title 14 CFR, Signature Engines, Inc. (SEI) hereby request the extension of Exemption No. 10108 from 14 CFR §120. 225(b) and §120.17(b) under docket number FAA-2010-0727. SEI requests that this extension be granted for a period of two years.

In doing so, SEI would be enabled to continue its op erations to fulfill the public need with our domestic helicopter tours while remaining ex empt from implementing separate and distinct drug and alcohol testing programs for our Part 135 and Part 91.147 operations.

Enclosed please find a copy of our original pe tition under exemption number 10108 and docket number FAA-2010-0727, along with its decision.

Sincerely,

Steven A. Darr Chief Inspector Signature Engines, Inc. 4760 Airport Road Cincinnati, Ohio 45226 (513) 871-9966

RE: Petition for Exemption Request

Dear Sir / Madam:

This is to seek your approval of Signature Engines, Inc. request for exemption from 14 CFR §120.117(b) and §120.225(b) in which our Part 91.147 operation is required to impl ement separate and distinct drug and alcohol testing programs from our Part 135 operation. We wish instead, to combine the Part 91.147 operation’s required program with the program already established under our Part 135 operation. This exemption would allow us to strea mline our drug and alcohol testin g program, thereby eliminating duplication of the entire process.

This request for exemption would not adversely affectsafety since the individuals whom perform safetysensitive functions under our Part 91.147 operation are the same individuals that are under our Part 135 operation’s established Antidrug and Alcohol Misuse Prevention Program.

It is our sincere belief that the granting of this exem ption is in the interest of the public, while providing no degradation to the level of safety, since it will en able us to fulfill the public need with our domestic helicopter tours.

Sincerely,

Steven A. Darr Chief Inspector Signature Engines, Inc. 4760 Airport Road Cincinnati, Ohio 45226 (513) 871-9966

### AAM-10-334-E Jul 29 2010

Exemption No. 10108 Regulatory Docket No. FAA-2010-0727

Mr. Steven A. Darr Chief Inspector Signature Engines, Inc. 4760 Airports Road Cincinnati, OH 45226

Dear Mr. Darr:

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 July 15, 2010, you petitioned the Federal Aviation Administration (FAA) on behalf Signature Engines, Inc. (Signature Engines), for an exemption from part 120 of Title 14, Code of Federal Regulations (14 CFR) . That exemption, if granted, would allow Signature Engines, which is operating under separate parts of the regulations, to cover its safety-sensitive employees under one testing program.

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 Signature Engines.

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. 9703 (copy enclosed), the FAA found that Solid Edge’s § 91.147 air tour operations were closely connected to its part 135 operations. The FAA also found that combining the petitioner’s two testing programs into one would be in the public interest and would maintain an equivalent level of safety to that

### 2

provided by the current regulations. Thus, the FAA concluded it was unnecessary to burden the petitioner by requiring it to conduct two separate testing programs.

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

 they do not differ materially from those presented by the petitioner in the enclosed grant of exemption;

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

 a grant of exemption is in the public interest.

Our Decision

Under the authority contained in 49 U.S.C. 40113 and 44701, which the FAA Administrator has delegated to me, I hereby grant Signature Engines, Inc., an exemption from part 120 to the extent necessary to allow Signature Engines which is operating under separate parts of the regulations, to cover its safety-sensitive employees under one testing program, subject to the

conditions and limitations described below.

Conditions and Limitations

1. Employees of Signature Engines are subject to the drug and alcohol regulations at all times while conducting operations under part 135 or part 91.

2. The drug and alcohol testing program must be implemented under the auspices of the Signature Engines part 135 operation, not under part 91.

This exemption terminates on July 31, 2012, unless sooner superseded or rescinded.

Sincerely,

/s/

Dr. James R. Fraiser Deputy Federal Air Surgeon
