Re: Application for Issuance ofSection 333 Exemption Dear Siror Madam, Pursuantto Section 333 ofthe FAA Modernization and Reform Act of2012 (the "Reform Act") and 14 CFR Part 11, Steve Young (Applicant), Private Pilot (cert# 3805867), and ownerof Petroleum Field Services, LLC ("PFS"), herebyappliesforan exemption from the listed Federal Aviation Regulations ("FARs") to allow commercial operation of designated UAS, provided such operations are conducted within and underthe conditions outlined herein oras may be established bythe FAA as required by Section 333. Commercial operation ofa UAS, as described herein, which are equipped with camera(s) and sensors, would provide professional services in the following areas: 1. Aerial photographyand/orvideo for public and/or private use including real estate, architecture, land surveying, engineering and other related professional activities. 2. Aerial inspection/photographyof residential/commercial structures undercontractwith the owners orlocal government authority. 4. Aerial inspection/photographyof residential/commercial utility infrastructure including but not limited to oil and gasfacilities, proposed development sites, reclamation projects, electrical power lines, wind turbines and cell towers. 5. Aerial video/photographyor providing live video feed to assistwith search and rescue operations in cases ofan emergencyor natural disasteronlywhen the local authorities or government has requested it by contract ordonation. The use ofthese unmanned aircraftwould be a much saferalternativeto current practices throughout industry. Petroleum Field Services, LLC ("PFS") IApplicant herewith applies forthe issuance of an exemption underSection 333 ofthe FAA Modernization and Reform Act of2012 based many previously issued exemptions including Exemption 11110 issued to Trimble Navigation Ltd. ("Trimble") on December 10, 2014 in FAA Docket 2014-0367. The requested exemption would allow PFS to operate the UX5, UXHP and the multirotorZX5 aircraft manufactured by Trimble or otherTrimble aircraft approved for commercial operations under Exemption 11110, as amended. PFS notes that the FAArecently authorized use ofthe Trimble aircraft by athird party in Exemption No. 11257, Regulatory Docket No. FAA-2014-0889, on April 2, 2015, under updated conditions, and PFS hereby confirms that it will accept such conditions as well as those set forth in Exemption No. 11240, Regulatory Docket No. FAA-2014-0894. The Trimble-drone ZX5 is a rotor aircraft weighing a maximum of 11 lbs. at takeoff (in any event, less than 55 lbs.), with payload. It will not operate at a speed greater than 87 knots. Preflight maintenance will be accomplished as set forth in the Operations Manual. All the listed aircraft will be operated in accordance with the procedures set forth in the manufacturers operating manuals. The FAA has issued exemption grants in circumstances similar in all material respects to those presented in this petition. In Exemption No. 11062 to Astraeus Aerial (see Docket No. FAA-2014-0352), No. 11109 to Clayco, Inc. 

### (see Docket No. FAA-2014-0507), No. 11112 to VDOS Global, LLC (see Docket No. FAA-2014-0382), and No. 11213 to Aeryon Labs, Inc. (see Docket No. FAA-2014-0642), the FAA found that the enhanced safety achieved using an unmanned aircraft ("UA") with the specifications described by the petitioner and carrying no passengers or crew, rather than a manned aircraft ofsignificantly greater proportions carrying crew in addition to flammable fuel, gave the FAA good cause to find that the UAS operation at issue was in the public interest. To the extent necessary, applicant refers the FAA to its exemption request submitted in Docket FAA-2015-1192 for a listing ofregulations (as amended by Exemption11110A) forwhich an exemption is being sought; a demonstration ofthe public interest; and a showing ofan equivalent level ofsafety. Based on the foregoing and due to the precedent set by previously approved FAA exemptions for aerial data collection PFS requeststhatthis request is granted. Finally, PFS and Applicant requestto be granted authorization to conduct commercial operations with all ofits aircraft under this exemption be allowed to operate without a separate Certificate ofOperation ("COA") in Class G airspace, at or below 400 feet AGL and at least 5 nautical miles from the geographic centerofan airport, unless a letter ofagreement with the airport's management is obtained. PFS acknowledges that undercurrent FAA guidance a separate Certificate ofWaiverorAuthorization ("COA") is required to fly at altitudes in excess of400 feet AGL, and it will applyfor COAs where required. PFS will also file NOTAMsfor its flights, as required.
