3rd Amendment to Exemption No. 11493 Regulatory Docket No. FAA‐2015‐0315 under Section

333 of the FAA Modernization and Reform Act of 2012 and 14 C.F.R. Part 11 regarding sUAS

use.

Dear Sir or Madam:

Regarding: Exemption No. 11493 Regulatory Docket No. FAA‐2015‐0315 approved on May 5,

2015.

Troy Built Models submitted its 1st amendment on June 25th, 2015. We are waiting for approval 

of the 1st amendment. Troy Built Models submitted its 2nd amendment on February 11, 2016. 

We are waiting for approval of the 2nd amendment. This 3rd amendment is different to the 1st

and second amendments and is in addition to the first and second amendments.

Troy Built Models (TBM) seeks to amend the original 333exemption 11493 as follows:

1) Additional aircraft – Pulse Aerospace Scout B1-100 Helicopter UAS

There has been no change in the conditions and reasons relative to public interest and safety 

that were the basis for granting the original exemption with the exception that this aircraft 

weighs more than 55 lbs. Its minimum takeoff weight is 100 lbs. and the maximum takeoff 

weight is 170 lbs.

It is a helicopter, not a multi-rotor. It is used for LIDAR and other heavy data collection 

sensors whose size and/or weights cannot be carried by sUAS at a maximum takeoff weight 

of under 55 lbs. 

LIDAR is used for a variety of important spatial geometric applications for government, public 

and commercial applications. 

The cost of the sUAS will be a minimum of $400,000 US dollars, therefore every attempt will 

be made to ensure extremely safe operations.

without issue. This original 333 exemption was for the following:

other exemptions to the small UAS rule are requested. All operations are during the day, within 

the line of sight, follow the airport restrictions, stay away from people, property and roads, 

operators will have pilot certificates and medicals, etc. The only exemption to the small UAS rule 

is to exceed the 55 lb. maximum takeoff weight maximum.

All operators will receive certified factory training as well as an internal Troy Built Models 

internal flight training program. Troy Built Models is a certified training company for a variety of 

aircraft as well.

amendment to the Exemption.
