Pursuant to Section 333 of the FAA Modernization and Reform Act of 2012 (the Reform Act) and 14 

C.F.R. Part 11.81, Centro Resources, hereby applies for an exemption from the listed Federal Aviation 

Regulations (FAR) to allow commercial operation of its small, unmanned aircraft system (sUAS) in 

photographing petrochemical facilities and wells for purposes of inspection, inventory and topography. 

AII operations shall be conducted within and under the conditions and limitations outlined previously by 

the FAA as required by Section 333 and conducted in compliance with the attached operator's manuals. 

1. Sections from which exemptions are sought: 

Application is hereby made for exemption from: 

a. 14 CFR Part 21, subpart H 

b. 14 CFR Part 61.101(e)

x. 91.417 

2. Relief sought: 

a. Centro Resources wishes to operate sUAS for commercial purposes to include (but not be limited to) 

photography, industrial inspections and inventory, and topography. This relief is sought because 

commercial use of sUAS is currently prohibited by law unless performed under an exemption. 

b. This exemption will cover use of the following airframes, all of which will weigh less than 55 pounds 

including payload and energy sources: 

i. DJI Inspire 1(see www.dji.com/product/inspire-1) 
ii. Other models to be added by future amendment to this exemption. 

3. Public benefit: 

Use of sUAS technology to obtain imagery, information and data currently obtained by use of manned 

flight or manual methods: 

a. Reduces statistical risk to human life due to manned aircraft accidents (e.g., infrastructure 

inspections) and due to other dangerous activities that can be avoided (e.g., scaffolding/rigging failures 

during stack or bridge inspections). 

b. Reduces the cost of obtaining such information, which benefits consumers and the economy. 

c. Reduces environmental impact by eliminating sources of hydrocarbon emissions from manned 

aircraft. 

4. Safety not adversely affected: 

a. Aircraft will be registered and marked in accordance with Section 44711 and Part 47 and Part 45, 

Subpart C. 

b. Aircraft will comply with maintenance and inspection requirernents of the manufacturer. AII repair 

and maintenance work will be conducted or approved by qualified personnel, and will require a test 

flight after such work. Records of all maintenance and repair work will be kept in a maintenance log for 

each aircraft. 

c. AII flight operations will be conducted by at least two individuals (PIC and observer) who will maintain 

verbal communication capability with each other at all times during the flight, and who will remain 

stationary on the ground during the flight operations: 

i. A Pilot In Command (PIC) who possess the following credentials: 

1. A Sport Aircraft Certificate or higher issued under 14 CFR 61 (private pilot license) screened by the 

TSA 

2. A Third Class medical certificate issued under 14 CFR 67. 

3. Successful completion of a UAS knowledge test in a specified form. 

4. At least 30 hours of flight experience with a UAS rotorcraft (or UAS fixed-wing in the case of fixedwing flight operations under this exemption) and 18 takeoffs and landings. 

5. At least 5 hours of flight experience and 3 takeoffs and landings in make and model being flown in the 

prior 90 days. Such cycles and hours may be gained during flights under this exemption if a safe distance 

is maintained from persons in accordance with 14 CFR 91.119. 

ii. A Visual Observer. 

iii. A Sensor Operator as necessary. 

d. AII flight operations will be conducted in accordance with valid Certificates of Authorization. 

e. AII flight operations will comply with the following: 

i. The manufacturers' user manuals. 
ii. Centro Resources Flight Operations and Procedures Manual (FOPM) and Aircraft Flight Manuals (AFM) 

which include lost communication and other emergency and safety procedures. 

iii. Conducted in VMC conditions during daylight hours. 

iv. PIC and VO will maintain visual-line-of-sight at all times. 

v. Pre-flight inspections (including ground control station, if any) and safety risk assessments will be 

conducted prior to each flight. 

vi. Flight altitudes will remain at or below 200 feet above ground level. 

vii. Flight ground speeds will not exceed 60 knots. 

viii. Not intrude into Class B, C or D airspace, or published approach, SID or STAR, or take place within 

specified nautical miles (NM) of airports as follows: 

1. Five NM from an airport having an operational control tower; or 

2. Three NM from an airport with a published instrument flight procedure, but not an operational tower; 

or 

3. Two NM from an airport without a published instrument flight procedure or an operational tower; or 

4. Two NM from a heliport with a published instrument flight procedure 

ix. Not be made near persons as required in 14 CFR 91.119 and not over persons on the ground without 

their prior permission. 

x. Each flight will be logged in both the PIC's logbook and the aircraft logbook. 

xi. Not operate below 50% of the battery or fuel capacity of the aircraft. 

xii. Any incidents will be reported within 24 hours of occurrence. 

xiii. Centro Resources will conduct safety meetings with owners and operators of facilities venting gas 

prior to operations. The meeting will determine safe operating distances from flare stacks, pressure 

relief valves and other vent gas instrumentation. 

xiv. AII other applicable regulations concerned with the operation of aircraft. 

f. Aircraft will use FCC compliant 2.4 GHz and 5.728 GHz - 5.85 GHz for command & control of the 

aircraft with well-defined and tested lost link procedures.
