September 11 , 2015 U. S. Department ofTransportation Docket Management System 1200 New Jersey Ave., SE Washington , DC 20590 Re: Application for Amendment to Exemption No. 12663, Seiler Instrument FAA Docket 2015-2130 Dear Sir or Madam : Seiler Instrument ("Seiler") is requesting an amendment to add the following aircraft to Exemption No. 12663 for commercial use in aerial data collection : 1. Trimble ZX5 2. 3D Robotics Iris 3. 3D Robotics SOLO 4. DJI Phantom 3 5. DJI Inspire 1 The Trimble ZX5 is a rotorcraft weighing a maximum of 11 lbs. at takeoff, 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 submitted with this request. The 3D Robotics Iris is a rotorcraft weighing a maximum of 4.5 lbs. at takeoff, 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 submitted with this request. The 3D Robotics SOLO is a rotorcraft weighing a maximum of 4.5 lbs. at takeoff, 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 submitted with this request. The DJI Phantom 3 is a rotorcraft weighing a maximum of4.51bs. at takeoff, 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 submitted with this request. The DJIInspire 1 is a rotorcraft weighing a maximum of 71bs. at takeoff, 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 submitted with this request. All the listed aircraftwill be operated in accordance with the procedures set forth in the submitted manuals. The FAA has issued exemption grants in circumstances similar in all material respects to those presented in this petition. In Exemption No. 111108 to Trimble Navigation (see Docket No. FAA-2014-0367), 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 FAAfound 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 of significantly greater proportions carryingcrew 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, Seiler refers the FAA to its original exemption request submitted in Docket FAA-2015-2130 for a listing of regulations forwhich an exemption is being sought; a demonstration of the public interest; and a showing ofan equivalent level of safety. Based on the foregoing and for all the reasons set forth in Seiler's previous filings in Docket 2015-2130, which are now incorporated by reference, Seiler notes that the FAA has granted similar exemptions, as set forth above, for aerial data collection, and it, therefore, believes that this amendment request is subject to the FAA's already announced Summary Exemption Process. Very truly ypurs,
