Re: Amendment to Exemption No 13171 Regulatory Docket No. FAA-2015-2140

Dear Madam, Sir,

On October 9, 2015, the FAA granted T Baker Smith, LLC a Section 333 rule exemption and a Small UAS Operations 200 feet and below for Commercial Purposes COA for the purposes of aerial data collection. This COA allows the use of the DJI Inspire 1 and SenseFly eBee UAS. The petitioner seeks an amendment to the existing 333 to allow, in addition to the UAS listed above, the use of a DJI S1000 Plus, Freefly ALTA and SenseFly eXom.

The DJI S1000 Plus is similar in aerodynamics to the Inspire 1. Although slightly larger, it is still well under 55lbs, weighing only 20lbs with max payload. This UAS is operated exactly the same as the Inspire 1 and has the same safety features. The DJI S1000 Plus is a more professional UAS and has the ability to carry better cameras and sensors than the hobby targeted Inspire 1.

The Freefly ALTA is also similar in aerodynamics to the Inspire 1. Also slightly larger, it is still well under 55lbs, weighing only 30lbs with max payload. This UAS is operated exactly the same as the Inspire 1 and has the same safety features. The Freefly ALTA is a more professional UAS and has the ability to carry better cameras and sensors than the hobby targeted Inspire 1.

The eXom is also similar in many regards to the Inspire 1 in size, weight and aerodynamics. However, the eXom is designed mainly for the purpose of aerial mapping and infrastructure inspections such as bridges, cell phone towers, industrial complexes, etc. As explained in detail below, the eXom is far more technologically advanced than the Inspire 1 as it has many built in sensors to facilitate its tasks. It is also a much more expensive platform. Current cost of the eXom is around $45,000 as compared to the $3200 for the Inspire 1. The intended uses of the eXom will not require flight above 200 feet and all requirements of the existing COA will be complied with. The eXom is unique in today's UAS marketplace as it is the only available UAS built specifically for low altitude infrastructure inspection and mapping.Page 2

The name and address of the applicant is: T Baker Smith, LLC Attention: Eric Deroche PO Box 2266 Houma, LA 70361 412 South Van Ave Houma, LA 70363 Telephone: (985) 868-1050 Email: eric.deroche@tbsmith.com

Granting this amendment will allow this new technology to be used in many industries and provide significant safety improvements and cost savings to these businesses. "The public good will is well served by allowing this amendment to be issued. All operations of the additional UAS will be in full compliance with the terms of the existing exemption. This exemption amendment request is similar to the already issued in precedent, and this request should qualify for summary processing as the FAA has already provided public notice of and granted similar exemptions. Such exemptions are No. 11659 in Regulatory Docket No. FAA–2015–0545 for Fovea Aero Systems LLC,
