Mr. Bartley J. Hallinan Port Towsend Air, LLC. Jefferson Co. International Airport 191 Airport Rd Port Townsend, WA 98368 Dear Mr. Hallinan: Exemption No. 10292 800 Independence Ave

.. SW. Washington. D.C. 20591

Regulatory DocketNo. FAA-2011-0595

This letter is to inform you thatwe have granted your request for exemption. Ittransmits our decision, explains its basis, and gives you the conditions and limitations ofthe exemption, including the date it ends. The Basis for Our Decision By letter dated June 2, 2011, you petitioned the Federal Aviation Administration (FAA) on behalfofPort Townsend Air, LLC. (PTA), for an exemption from part 120, subpart A, D, E ofTitle 14, Code ofFederal Regulations (14 CFR) to the extent necessary to allow PTAto cover its safety-sensitive employees under one testing program while operating under separate parts ofthe regulation. The FAA has determined that good cause exists for not publishing a summary ofthe petition in theFederal Register because the requested exemption would not set a precedent, and any delay in acting on this petition would be detrimental to PTA. The FAAhas issued a grant ofexemption in circumstances similarin all material respects to those presented in your petition. In Grant ofExemptionNo. 9703 (copy enclosed), the FAA found that Solid Edge's 

### § 91.147 airtour 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

AAM-11-332-Eprovided by the current regulations. Thus, the FAA concluded itwas unnecessary to burden the petitioner by requiring itto conducttwo separate testing programs. Having reviewed your reasons for requesting an exemption, I find that2

• they are similar in all material respects to reliefpreviously requested in the enclosed Grant ofExemptionNo. 9703; • the reasons stated by the FAAfor granting the enclosed Grant ofExemption No. 9703 also apply tothe situation you present; and • a grant ofexemption is in the public interest. Our Decision Underthe authority contained in 49U.S.C. 40113 and 44701, which the FAAAdministrator has delegated to me, I hereby grantPort Townsend Air, LLC. an exemption from 14 CFRpart 120 to the extent necessary to allow PTAto cover its safety-sensitive employees under one testing program while operating under separate parts ofthe regulation, subjectto the conditions and limitations described below. · Conditions and Limitations 1. Employees ofPort Townsend Air 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 program mustbe implemented underthe auspices ofthe Port Townsend Airpart 135 operation, not under part 91. This exemption terminates on July 31, 2013, unless sooner superseded orrescinded. Sincerely, 

### Is/ FrederickE. Tilton, M.D. Federal Air Surgeon
