Exemption No. 12482

Regulatory Docket No. FAA–2015–1850

Mr. Ryan Joseph Cathey

440 East Route 66

Glendora, CA 91740

Dear Mr. Cathey:

This letter is to inform you that we have granted your request for exemption. It transmits our 

decision, explains its basis, and gives you the conditions and limitations of the exemption, 

including the date it ends.

By letter dated May 8, 2015, you petitioned the Federal Aviation Administration (FAA) for an 

exemption. The petitioner requested to operate an unmanned aircraft system (UAS) to 

conduct high quality imaging for a variety of commercial, public, and residential uses, 

specifically targeting construction sites before and after, appraisals, real-estate marketing, 

motion picture filming, aerial acquisitions used for inspections of public and private 

structures, and search and rescue operations.

See Appendix A for the petition submitted to the FAA describing the proposed operations and 

the regulations that the petitioner seeks an exemption.

The FAA has determined that good cause exists for not publishing a summary of the petition 

in the Federal Register because the requested exemption would not set a precedent, and any 

delay in acting on this petition would be detrimental to the petitioner.

Airworthiness Certification

The UAS proposed by the petitioner is a DJI Phantom 3.
2

In accordance with the statutory criteria provided in Section 333 of Public Law 112−95 in 

reference to 49 U.S.C. § 44704, and in consideration of the size, weight, speed, and limited 

operating area associated with the aircraft and its operation, the Secretary of Transportation 

has determined that this aircraft meets the conditions of Section 333. Therefore, the FAA 

finds that relief from 14 CFR part 21, Certification procedures for products and parts, 

Subpart H—Airworthiness Certificates, and any associated noise certification and testing 

requirements of part 36, is not necessary.

The Basis for Our Decision

You have requested to use a UAS for aerial data collection1. The FAA has issued grants of 

exemption in circumstances similar in all material respects to those presented in your petition. 

In Grants of Exemption Nos. 11062 to Astraeus Aerial (see Docket No. FAA−2014−0352), 

11109 to Clayco, Inc. (see Docket No. FAA−2014−0507), 11112 to VDOS Global, LLC (see

Docket No. FAA−2014−0382), and 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 of significantly greater proportions, carrying crew in 

addition to flammable fuel, gives the FAA good cause to find that the UAS operation enabled 

by this exemption is in the public interest.

Having reviewed your reasons for requesting an exemption, I find that—

 They are similar in all material respects to relief previously requested in Grant of 

Exemption Nos. 11062, 11109, 11112, and 11213;

 The reasons stated by the FAA for granting Exemption Nos. 11062, 11109, 11112, and 

11213 also apply to the situation you present; and 

 A grant of exemption is in the public interest.

Our Decision

In consideration of the foregoing, I find that a grant of exemption is in the public interest. 

Therefore, pursuant to the authority contained in 49 U.S.C. 106(f), 40113, and 44701, 

delegated to me by the Administrator, Ryan J. Cathey is granted an exemption from 14 CFR 

§§ 61.23(a) and (c), 61.101(e)(4) and (5), 61.113(a), 61.315(a), 91.7(a), 91.119(c), 91.121, 

91.151(a)(1), 91.405(a), 91.407(a)(1), 91.409(a)(1) and (2), and 91.417(a) and (b), to the 

extent necessary to allow the petitioner to operate a UAS to perform aerial data collection. 

This exemption is subject to the conditions and limitations listed below.

 

1 Aerial data collection includes any remote sensing and measuring by an instrument(s) aboard the UA. 

Examples include imagery (photography, video, infrared, etc.), electronic measurement (precision surveying, RF 

analysis, etc.), chemical measurement (particulate measurement, etc.), or any other gathering of data by 

instruments aboard the UA.

Conditions and Limitations

In this grant of exemption, Ryan J. Cathey is hereafter referred to as the operator.

Failure to comply with any of the conditions and limitations of this grant of exemption will be 

grounds for the immediate suspension or rescission of this exemption.

1. Operations authorized by this grant of exemption are limited to the DJI Phantom 3

when weighing less than 55 pounds including payload. Proposed operations of any 

other aircraft will require a new petition or a petition to amend this exemption.

2. Operations for the purpose of closed-set motion picture and television filming are not 

permitted. 

3. The UA may not be operated at a speed exceeding 87 knots (100 miles per hour). The 

exemption holder may use either groundspeed or calibrated airspeed to determine 

compliance with the 87 knot speed restriction. In no case will the UA be operated at 

airspeeds greater than the maximum UA operating airspeed recommended by the 

aircraft manufacturer.

4. The UA must be operated at an altitude of no more than 400 feet above ground level 

(AGL). Altitude must be reported in feet AGL.

5. The UA must be operated within visual line of sight (VLOS) of the PIC at all times. 

This requires the PIC to be able to use human vision unaided by any device other than 

corrective lenses, as specified on the PIC’s FAA-issued airman medical certificate or 

U.S. driver’s license.

6. All operations must utilize a visual observer (VO). The UA must be operated within 

the visual line of sight (VLOS) of the PIC and VO at all times. The VO may be used 

to satisfy the VLOS requirement as long as the PIC always maintains VLOS 

capability. The VO and PIC must be able to communicate verbally at all times;

electronic messaging or texting is not permitted during flight operations. The PIC 

must be designated before the flight and cannot transfer his or her designation for the 

duration of the flight. The PIC must ensure that the VO can perform the duties 

required of the VO.

7. This exemption and all documents needed to operate the UAS and conduct its 

operations in accordance with the conditions and limitations stated in this grant of 

exemption, are hereinafter referred to as the operating documents. The operating 

documents must be accessible during UAS operations and made available to the 

Administrator upon request. If a discrepancy exists between the conditions and 

limitations in this exemption and the procedures outlined in the operating documents, 

the conditions and limitations herein take precedence and must be followed. 
4

Otherwise, the operator must follow the procedures as outlined in its operating 

documents. The operator may update or revise its operating documents. It is the 

operator’s responsibility to track such revisions and present updated and revised 

documents to the Administrator or any law enforcement official upon request. The 

operator must also present updated and revised documents if it petitions for extension 

or amendment to this grant of exemption. If the operator determines that any update 

or revision would affect the basis upon which the FAA granted this exemption, then 

the operator must petition for an amendment to its grant of exemption. The FAA’s 

UAS Integration Office (AFS−80) may be contacted if questions arise regarding 

updates or revisions to the operating documents.

8. Any UAS that has undergone maintenance or alterations that affect the UAS operation 

or flight characteristics, e.g., replacement of a flight critical component, must undergo 

a functional test flight prior to conducting further operations under this exemption. 

Functional test flights may only be conducted by a PIC with a VO and must remain at 

least 500 feet from other people. The functional test flight must be conducted in such 

a manner so as to not pose an undue hazard to persons and property.

9. The operator is responsible for maintaining and inspecting the UAS to ensure that it is 

in a condition for safe operation.

10. Prior to each flight, the PIC must conduct a pre-flight inspection and determine the 

UAS is in a condition for safe flight. The pre-flight inspection must account for all 

potential discrepancies, e.g., inoperable components, items, or equipment. If the 

inspection reveals a condition that affects the safe operation of the UAS, the aircraft is 

prohibited from operating until the necessary maintenance has been performed and the 

UAS is found to be in a condition for safe flight.

11. The operator must follow the UAS manufacturer’s maintenance, overhaul, 

replacement, inspection, and life limit requirements for the aircraft and 

aircraft components.

12. Each UAS operated under this exemption must comply with all manufacturer 

safety bulletins.

13. Under this grant of exemption, a PIC must hold either an airline transport, 

commercial, private, recreational, or sport pilot certificate. The PIC must also hold a 

current FAA airman medical certificate or a valid U.S. driver’s license issued by a 

state, the District of Columbia, Puerto Rico, a territory, a possession, or the Federal 

government. The PIC must also meet the flight review requirements specified in 

14 CFR § 61.56 in an aircraft in which the PIC is rated on his or her pilot certificate.

14. The operator may not permit any PIC to operate unless the PIC demonstrates the 

ability to safely operate the UAS in a manner consistent with how the UAS will be 
5

operated under this exemption, including evasive and emergency maneuvers and 

maintaining appropriate distances from persons, vessels, vehicles and structures. PIC 

qualification flight hours and currency must be logged in a manner consistent with 

14 CFR § 61.51(b). Flights for the purposes of training the operator’s PICs and VOs 

(training, proficiency, and experience-building) and determining the PIC’s ability to 

safely operate the UAS in a manner consistent with how the UAS will be operated 

under this exemption are permitted under the terms of this exemption. However, 

training operations may only be conducted during dedicated training sessions. During 

training, proficiency, and experience-building flights, all persons not essential for 

flight operations are considered nonparticipants, and the PIC must operate the UA 

with appropriate distance from nonparticipants in accordance with 14 CFR § 91.119.

15. UAS operations may not be conducted during night, as defined in 14 CFR § 1.1. All 

operations must be conducted under visual meteorological conditions (VMC). Flights 

under special visual flight rules (SVFR) are not authorized.

16. The UA may not operate within 5 nautical miles of an airport reference point (ARP) as 

denoted in the current FAA Airport/Facility Directory (AFD) or for airports not 

denoted with an ARP, the center of the airport symbol as denoted on the current 

FAA-published aeronautical chart, unless a letter of agreement with that airport’s 

management is obtained or otherwise permitted by a COA issued to the exemption 

holder. The letter of agreement with the airport management must be made available 

to the Administrator or any law enforcement official upon request.

17. The UA may not be operated less than 500 feet below or less than 2,000 feet 

horizontally from a cloud or when visibility is less than 3 statute miles from the PIC.

18. If the UAS loses communications or loses its GPS signal, the UA must return to a 

pre-determined location within the private or controlled-access property.

19. The PIC must abort the flight in the event of unpredicted obstacles or emergencies.

20. The PIC is prohibited from beginning a flight unless (considering wind and forecast 

weather conditions) there is enough available power for the UA to conduct the 

intended operation and to operate after that for at least five minutes or with the reserve 

power recommended by the manufacturer if greater.

21. Air Traffic Organization (ATO) Certificate of Waiver or Authorization (COA). All 

operations shall be conducted in accordance with an ATO-issued COA. The 

exemption holder may apply for a new or amended COA if it intends to conduct 

operations that cannot be conducted under the terms of the attached COA.

22. All aircraft operated in accordance with this exemption must be identified by serial 

number, registered in accordance with 14 CFR part 47, and have identification 
6

(N−Number) markings in accordance with 14 CFR part 45, Subpart C. Markings must 

be as large as practicable.

23. Documents used by the operator to ensure the safe operation and flight of the UAS and 

any documents required under 14 CFR §§ 91.9 and 91.203 must be available to the 

PIC at the Ground Control Station of the UAS any time the aircraft is operating. 

These documents must be made available to the Administrator or any law enforcement 

official upon request.

24. The UA must remain clear and give way to all manned aviation operations and 

activities at all times. 

25. The UAS may not be operated by the PIC from any moving device or vehicle. 

26. All Flight operations must be conducted at least 500 feet from all nonparticipating 

persons, vessels, vehicles, and structures unless:

a. Barriers or structures are present that sufficiently protect nonparticipating persons 

from the UA and/or debris in the event of an accident. The operator must ensure 

that nonparticipating persons remain under such protection. If a situation arises 

where nonparticipating persons leave such protection and are within 500 feet of 

the UA, flight operations must cease immediately in a manner ensuring the safety 

of nonparticipating persons; and

b. The owner/controller of any vessels, vehicles or structures has granted permission 

for operating closer to those objects and the PIC has made a safety assessment of 

the risk of operating closer to those objects and determined that it does not 

present an undue hazard.

The PIC, VO, operator trainees or essential persons are not considered 

nonparticipating persons under this exemption.

27. All operations shall be conducted over private or controlled-access property with 

permission from the property owner/controller or authorized representative. 

Permission from property owner/controller or authorized representative will be 

obtained for each flight to be conducted.

28. Any incident, accident, or flight operation that transgresses the lateral or vertical 

boundaries of the operational area as defined by the applicable COA must be reported 

to the FAA's UAS Integration Office (AFS−80) within 24 hours. Accidents must be 

reported to the National Transportation Safety Board (NTSB) per instructions 

contained on the NTSB Web site: www.ntsb.gov.

BACKGROUND

Unmanned Aircraft Systems: DJI Phantom 3 Professional UASs

Ryan Joseph Cathey seeks an exemption to operate DJI systems for compensation 

or hire within the NAS. The DJI Phantom 3 Professional UASs are vertical takeoff and 

landing (VTOL) Unmanned Aircraft (UA) with a Ground Control Station (GCS) utilizing 

electronic tablet or smart phone systems. The DJI Phanton 3 Professional has a maximum 

gross weight of approximately 2 pounds 12 ounces, while having a length of 16 inches 

width of 16 inches, height of 8 inches, and a maximum speed of approximately 29 knots. 

The DJI Phanton 3 Professional UAs are equipped with four main rotors; driven by 

Lithium Polymer battery powered electric motors. 

The DJI Phantom 3 Professional UAs that will be operated by Ryan Joseph 

Cathey will be registered in accordance with 49 U.S.C. 44103, Registration of Aircraft, 

as well as 14 C.F.R Part 47, Aircraft Registration, and marked in accordance with 14 

C.F.R. Part 45, Identification and Registration Marking.

BASIS FOR PETITION

Petitioner, Ryan Joseph Cathey, pursuant to the provisions of the Federal 

Aviation Regulations (14 C.F.R. § 11.61) and the FAA Modernization and Reform Act 

of 2012 (FMRA), Section 333, Special Rules for Certain Unmanned Aircraft Systems, 

hereby petitions the Administrator to commercially operate the DJI Phantom 3 

Professional UASs in the National Airspace System (NAS), and for an exemption 

from the 
6

requirements of 14 C.F.R §§ 61.113(a) & (b), 91.7(a), 91.121, 91.151(b), 91.405(a), 

91.407(a)(1), 91.409(a)(1) & (a)(2), and 91.417(a) & (b). 

In consideration of the speed, weight, size, and limited operating area associated 

with the unmanned aircraft and its operation, Ryan Joseph Cathey operation of DJI 

Phanton 3 Professional UASs meets the conditions of FMRA Section 333 and 

therefore, will not require an airworthiness certificate in accordance with 14 C.F.R. Part 

21, Subpart H. 

Accordingly, Ryan Joseph Cathey requests relief from Sections 91.405(a), 

91.407(a)(1), 91.409(a)(1) & (a)(2), and 91.417(a) & (b), as these sections set forth 

requirements for maintenance that only apply to aircraft with an airworthiness certificate. 

Ryan Joseph Cathey submits that the requested relief is proper since an 

equivalent level of safety will be ensured. Ryan Joseph Cathey will use experienced 

personnel or technicians to perform maintenance, alterations, or preventive maintenance 

on the UASs using the methods, techniques, and practices prescribed in the operating 

documents (i.e., Monthly Maintenance Log, and DJI Phanton 3 Professional Instruction 

Manual). Furthermore, Ryan Joseph Cathey will document and maintain all 

maintenance records for the DJI Phanton 3 Professional UASs. 

Relief from certain requirements of Section 61.113(a) and (b), entitled Private pilot 

privileges and limitations: Pilot in command, is requested by Ryan Joseph Cathey to the 

extent necessary to allow a Pilot in Command (PIC) not holding a certificate, or an airman 

medical certificate, and who has demonstrated, by meeting minimum flight- hour and 

currency requirements, that the PIC is able to safely operate the 

DJI Phanton 3 Professional UASs in a manner consistent with this 
7

exemption, including evasive and emergency maneuvers and maintaining appropriate 

distances from people, vessels, vehicles and structures. 

Ryan Joseph Cathey seeks relief from Section 91.7(a), entitled Civil aircraft 

airworthiness, because the DJI Phanton 3 Professional UASs do not require an 

airworthiness certificate in accordance with 14 C.F.R. Part 21, Subpart H. As such, Ryan 

Joseph Cathey submits that he will ensure that the DJI Phanton 3 Professional UASs are 

in an airworthy condition, prior to every flight, by determining that the UASs are in 

compliance with the operating documents (i.e., Monthly Maintenance Log, and DJI 

Phanton 3 Professional Instruction Manual), and that the aircraft are in a condition for safe 

flight. 

Ryan Joseph Cathey also seeks an exemption from the requirements of Section 

91.121, entitled Altimeter Settings, as the DJI Phanton 3 Professional UAs will not have a 

typical barometric altimeter onboard. However, altitude information of the DJI Phanton 3 

Professional UAs will be provided to the PIC via Global Positioning System (GPS) 

equipment and radio communications telemetry data link, which downlinks from the UA 

to the GCS for active monitoring of the flight path. This altitude information, combined 

with Ryan Joseph Cathey's operation of the DJI Phanton 3 Professional UASs within 

visual line of sight, at or below 400 feet AGL, will ensure a level of safety equivalent to 

Section 91.121. 

Additionally, Ryan Joseph Cathey seeks an exemption from the requirements of 

Section 91.151(b), entitled Fuel requirements for flight in VFR conditions. Ryan Joseph 

Cathey submits that safety will not be affected by operation of the DJI Phanton 3 

Professional UAs during daylight hours in visual meteorological conditions (VMC) 
8

under visual flight rules (VFR), with enough battery power to fly for a total duration of 

approximately 13.5 minutes to the first point of intended landing and, assuming normal 

cruising speed, to fly after that for at least 4.5 minutes. 

In accordance with 14 C.F.R. § 11.81, Ryan Joseph Cathey provides the following 

information in support of its petition for exemption:

C. The Extent Of Relief Ryan Joseph Cathey Seeks And The Reason Ryan Joseph Cathey

Seeks The Relief. 

1. Extent Of Relief Ryan Joseph Cathey Seeks And The Reason Ryan 

Joseph Cathey Seeks Relief From Section 61.113(a) And (b).

Relief from Section 61.113(a) and (b) entitled Private pilot privileges and 

limitations: Pilot in command, is requested to the extent necessary to allow a PIC not 

holding any pilot certificate, or a current and valid airman medical certificate, but who has 

met certain flight-hour and currency requirements, to conduct the proposed UAS flight 

operations for compensation or hire. 

This relief is requested since the limitations set forth in Section 61.113(a) and (b) 

state that a private pilot may, for compensation or hire, act as PIC of an aircraft in 

connection with any business or employment if: (1) The flight is only incidental to that 

business or employment; and (2) The aircraft does not carry passengers or property for 

compensation or hire. 

As set forth more fully below, Ryan Joseph Cathey submits that an equivalent level 

of safety will be maintained because no PIC will be allowed to operate the DJI Phanton 3 

Professional UAS unless that PIC has met certain flight-hour and currency requirements, 

demonstrating that the PIC is able to safely operate the DJI Phanton 3 Professional in a 

manner consistent with the operations specifications as described in this exemption, 

including evasive and emergency maneuvers, as well as maintaining appropriate distances 

from people, vessels, vehicles and structures.
13

Further, Ryan Joseph Cathey submits that all flights of the DJI Phanton 3 

Professional UASs, conducted by the PIC pursuant to the grant of this Petition: (1) will be 

incidental to Ryan Joseph Cathey's business; and (2) will not carry passengers or property 

for compensation or hire. 

2. Extent Of Relief Ryan Joseph Cathey Seeks And The Reason Ryan 

Joseph Cathey Seeks Relief From Section 91.7(a).

Relief from Section 91.7(a) entitled Civil aircraft airworthiness, is requested to the 

extent required to allow Ryan Joseph Cathey to determine that the DJI Phanton 3 

Professional UASs are in airworthy condition prior to every flight by ensuring that the 

UAS is in compliance with the operating documents (i.e., the Ryan Joseph Cathey Aerial 

Operations Manual, Monthly Maintenance Log, and DJI Phanton 3 Professional

Instruction Manual). 

Ryan Joseph Cathey seeks the requested relief because the DJI Phanton 3 

Professional UASs do not require an airworthiness certificate in accordance with 14 C.F.R. 

Part 21, Subpart H. Therefore, Ryan Joseph Cathey will ensure that the DJI Phanton 3 

Professional UASs are in airworthy condition based upon its compliance with the 

operating documents (i.e., Monthly Maintenance Log, and DJI Phanton 3 Professional

Instruction Manual) prior to every flight, and further, determine that the aircraft are in 

condition for safe flight, as stated in the conditions and limitationsbelow

Extent Of Relief Ryan Joseph Cathey, Seeks From Section 91.121.

Relief from Section 91.121, entitled Altimeter settings, may be required to allow 

flight operations of the DJI Phanton 3 Professional UASs, which utilize a barometric 

pressure sensor, GPS equipment, and a radio communications telemetry data link to 

downlink altitude information from the UA to the PIC at the ground control station 
14

(GCS). Since the FAA requires that any altitude information concerning UAS operations be 

reported to air traffic control (ATC) in feet above ground level (AGL), Ryan Joseph Cathey

seeks the requested relief because the DJI Phanton 3 Professional UA’s altimeter may be 

set on the ground to zero feet AGL, rather than the local barometric pressure or field 

altitude, before each flight. 

Considering the limited altitude of the proposed operations, relief from 14 CFR 

91.121 is sought to the extent necessary to comply with the applicable conditions and 

limitations stated below. As more fully set forth herein, an equivalent level of safety will 

be maintained since the DJI Phanton 3 Professional UAs are equipped with a barometric 

pressure sensor and GPS equipment, which automatically ensures that a ground level 

pressure setting will be established prior to each flight, and provides the PIC with altitude 

information of the UA on the heads-up display of the GCS. 

4. Extent Of Relief Ryan Joseph Cathey Seeks And The Reason Ryan 

Joseph Cathey Seeks Relief From Section 91.151(b).

Relief from Section 91.151(b) entitled Fuel requirements for flight in VFR 

conditions, is requested to the extent required to allow flights of the battery powered DJI 

Phanton 3 Professional UAs during daylight hours in visual meteorological conditions 

(VMC), under visual flight rules (VFR), for a total duration of 13.5 minutes to the first 

point of intended landing and, assuming normal cruising speed, to fly after that for at least 

4.5 minutes. Ryan Joseph Cathey seeks the requested relief because without an exemption 

from Section 91.151(b), the flight time duration of the battery powered DJI Phanton 3 

Professional UAs will severely constrain the practicality of any aerial video or still photo 

flight operations that Ryan Joseph Cathey proposes to conduct pursuant to this Petition. 
15

Significantly, as set forth below, the technical specifications of the DJI Phanton 3 

Professional UASs, the DJI Phanton 3 Professional operating documents, and Ryan 

Joseph Cathey's proposed operating limitations, ensure that Ryan Joseph Cathey will 

safely operate the battery powered DJI Phanton 3 Professional UAs during daylight hours 

in visual meteorological conditions (VMC), under visual flight rules (VFR), with enough 

battery power to fly for a total duration of 13.5 minutes to the first point of intended 

landing and, assuming normal cruising speed, to fly after that for at least 4.5 minutes.

5. Extent Of Relief Ryan Joseph Cathey Seeks And The Reason Ryan 

Joseph Cathey Seeks Relief From Sections 91.405(a), 91.407(a)(1),

91.409(a)(1) & (a)(2), And 91.417(a) & (b).

Since Sections 91.405(a), 91.407(a)(1), 91.409(a)(1) & (a)(2), and 91.417(a) & (b) 

only apply to aircraft with an airworthiness certificate, Ryan Joseph Cathey requests 

relief from these Sections because the DJI Phanton 3 Professional UASs do 

not require airworthiness certificates. As set forth more fully below, the DJI Phantom 3

Professional UASs meet the conditions of FMRA Section 333 for operation without an 

airworthiness certificate. Accordingly, Ryan Joseph Cathey will use trained technicians to 

perform maintenance, alterations, or preventive maintenance on the UASs using the 

methods, techniques, and practices prescribed in the UAS operating documents (i.e., the 

Ryan Joseph Cathey Aerial Operations Manual, Monthly Maintenance Log, and DJI 

Phanton 3 Professional Instruction Manual). Furthermore, Ryan Joseph Cathey will 

document and maintain all maintenance records for the DJI Phanton 3 Professional UASs. 

D. The Reasons Why Granting Ryan Joseph Cathey Request Would Be In The 

Public Interest; That Is, How It Would Benefit The Public As A 

Whole.
16

Granting the present Petition will further the public interest by allowing Ryan 

Joseph Cathey to safely, efficiently, and economically perform aerial video and 

photography of construction sites, real estate, and landscape over certain areas of the 

United States. 

Additionally, use of the DJI Phanton 3 Professional UASs will 

decrease congestion of the NAS, reduce pollution, and provide significant benefits to 

the economy. Notably, the benefits of Ryan Joseph Cathey's proposed operation of the 

DJI Phanton 3 Professional UASs will be realized without implicating any privacy 

issues. 

1. The Public Will Benefit From Decreased Congestion Of The NAS.

The DJI Phanton 3 Professional UAs are battery powered and serve as a safe, 

efficient, and economical alternative to the manned aircraft traditionally utilized to obtain 

aerial imagery. By reducing the amount of manned aircraft needed to perform aerial 

acquisitions, an exemption allowing the use of a DJI Phanton 3 Professional UAS would 

reduce the amount of manned aircraft in the NAS, reduce noise and air pollution, as well 

as increase the safety of life and property in the air and on the ground. 

Furthermore, by reducing the number of manned aircraft operating in the NAS, 

congestion around airports caused by arriving and departing aircraft will be reduced. The 

DJI Phanton 3 Professional UAs do not require an airport to takeoff or land. Likewise, a 

reduction of manned aircraft conducting aerial video and photography missions would 

result in fewer aircraft that must be handled by air traffic control during the ground, 

takeoff, departure, arrival, and landing phases of flight operations.

2. The Public Will Benefit From The Safety And Efficiency Of The DJI 

Phanton 3 Professional UASs.
17

Conducting aerial acquisitions with the DJI Phanton 3 Professional UASs, instead 

of manned aircraft, will greatly benefit the public by drastically reducing the levels of air 

and noise pollution generated during traditional aerial video and still photography flight 

operations. By using battery power and electric motors, the DJI Phanton 3 Professional

UASs produce no air pollution, and is the most viable environmentally conscious 

alternative to the cabin class, six cylinder internal combustion engine aircraft that are 

typically utilized for aerial video and photography, while burning approximately 20-30 

gallons per hour of leaded aviation fuel. The DJI Phanton 3 Professional UAs, while 

reducing the carbon footprint of aerial acquisitions, also eliminates noise pollution, as the 

UAs are propelled by battery powered electric motors, rather than an internal combustion 

engine. 

By using the DJI Phanton 3 Professional UASs to perform aerial acquisitions, the 

substantial risk to life and property in the air and on the ground, which is usually 

associated with traditional manned aircraft flight operations, will be substantially reduced 

or completely eliminated. Aside from the lack of flight crew members located onboard the 

aircraft, the DJI Phanton 3 Professional UAs (weighing approximately 2 pounds 12

ounces, at their maximum gross weights with lengths and widths of 16 inches , and with 

no fuel on board), has less physical potential for collateral damage to life and property on 

the ground, and in the air, compared to the manned aircraft that typically conduct similar 

operations (weighing approximately 6,000 pounds with a wingspan of approximately 42

feet, a length of 34 feet, and a fuel capacity of 180 gallons). 
18

3. Performing Aerial Video and Photography Operations With The DJI 

Phanton 3 Professional UASs Will Benefit The Economy.

In addition to being safe and efficient, the DJI Phanton 3 Professional UASs are 

also an economical alternative to using manned aircraft to conduct similar aerial 

operations. As such, operation of the DJI Phanton 3 Professional UASs will allow United 

States based companies, like Ryan Joseph Cathey, to remain competitive and contribute to 

growth of the U.S. economy. Specifically, with the rising cost of aviation fuel and the 

Environmental Protection Agency (“EPA”) regulatory actions phasing out leaded aviation 

fuels, U.S. owned and operated companies must adopt new and alternative technology in 

order to remain competitive. Operating the battery powered DJI Phanton 3 Professional

UASs is one such technology that not only allows companies greater operational flexibility 

compared to manned aircraft, but provides such flexibility without the high operational 

cost of a traditional manned aircraft. 

By operating the DJI Phanton 3 Professional UASs, companies such as Ryan 

Joseph Cathey, can remain competitive and profitable, and therefore, provide greater job 

stability to employees and contractors, which will ultimately contribute to growth of the 

U.S. economy. Improved financial performance of U.S. companies, through commercial 

use of the DJI Phanton 3 Professional UASs, provides a stable workforce that increases 

consumer spending; improves local, state, and federal tax revenues; and allows 

companies to invest in research and development in order to remain competitive both in 

the United States and abroad. 

4. There Are No Privacy Issues.

Similar to the manned aerial acquisition flight operations that have been conducted for 

decades, Ryan Joseph Cathey's proposed operation of the DJI Phanton 3 Professional
19

UASs will not implicate any privacy issues. Specifically, the DJI Phantom 3

Professional UASs will be operated only in compliance with operating 

documents (i.e., the Ryan Joseph Cathey Aerial Operations Manual, Monthly 

Maintenance Log, and DJI Phanton 3 Professional Instruction Manual) 

which requires 

property owner involvement as well as local law enforcement notification, and in 

accordance with the Federal Aviation Regulations, including the minimum altitude 

requirements of 14 C.F.R. § 91.119. 

E. The Reasons Why Granting The Exemption Would Not Adversely Affect Safety, 

Or How The Exemption Would Provide A Level Of Safety At Least Equal To That 

Provided By The Rule From Which Ryan Joseph Cathey Seeks Exemption. 

1. Reasons Why The DJI Phanton 3 Professional UAs Meet The Conditions Of 

The FAA Modernization and Reform Act of 2012 (FMRA) Section 333.

In consideration of the size, weight, speed, and limited operating area associated 

with the unmanned aircraft and its operation, Ryan Joseph Cathey operation of the DJI 

Phanton 3 Professional UASs meet the conditions of FMRA Section 333, and will not 

require an airworthiness certificate in accordance with 14 C.F.R. Part 21, Subpart H. 

Section 333 provides authority for a UAS to operate without airworthiness 

certification and sets forth requirements for considering whether a UAS will create a 

hazard to users of the NAS or the public, or otherwise pose a threat to national security. 

Specifically, FMRA Section 333 states the following, in part: 

(a) In General.--Notwithstanding any other requirement of this subtitle, and not 

later than 180 days after the date of enactment of this Act, the Secretary of 

Transportation shall determine if certain unmanned aircraft systems may 

operate safely in the national airspace system before completion of the plan 

and rulemaking required by section 332 of this Act or the guidance required by 

section 334 of this Act. 
20

(b) Assessment of Unmanned Aircraft Systems.--In making the determination under 

subsection (a), the Secretary shall determine, at a minimum--

(1) which types of unmanned aircraft systems, if any, as a result of their 

size, weight, speed, operational capability, proximity to airports and 

populated areas, and operation within visual line of sight do not create 

a hazard to users of the national airspace system or the public or pose a 

threat to national security; and

(2) whether a certificate of waiver, certificate of authorization, or 

airworthiness certification under section 44704 of title 49, United States 

Code, is required for the operation of unmanned aircraft systems 

identified under paragraph (1). 

(c) Requirements for Safe Operation.--If the Secretary determines under this 

section that certain unmanned aircraft systems may operate safely in the 

national airspace system, the Secretary shall establish requirements for the safe 

operation of such aircraft systems in the national airspace system. 

In seeking this exemption, Ryan Joseph Cathey submits that the DJI Phantom 3

Professional UASs can operate safely in the NAS pursuant to FMRA Section 

333, as demonstrated by: (a) the characteristics of the DJI Phantom 3 Professional

UASs; (b) the pilot certification requirement; and (c) the specific operating 

limitations. 

a. The Specifications Of The DJI Phanton 3 Professional UASs 

Demonstrate Its Safe Characteristics.

The DJI Phanton 3 Professional UASs do not create a hazard to users of the NAS 

or the public, or otherwise pose a threat to national security considering its size, weight, 

speed, and operational capability. 

i. Technical Specifications Of The DJI Phanton 3 Professional 

UASs.

The technical specifications of the DJI Phanton 3 Professional UASs are set forth 

by the DJI Phanton 3 Professional Specifications, attached hereto as Exhibit A. 
21

ii. The DJI Phanton 3 Professional UASs Autonomous Flight And 

Navigation Modes Enable The UASs To Remain Within A Defined 

Operational Area.

The DJI Phanton 3 Professional UASs may be operated in both manual and fully 

autonomous flight modes. A complete description of the flight and navigational modes of 

the DJI Phanton 3 Professional UASs is provided at pages 39-47 of the DJI Phanton 3 

Professional User Manual, attached hereto as Exhibit B.

iii. The DJI Phanton 3 Professional UASs Are Designed For 

Automatic Return To Home Point Or Hover In The Event Of Loss 

Of The Control Link Or Navigation.

When the Control Link is lost, the DJI Phanton 3 Professional UAs will remain 

stationary, in flight, for 3 seconds or more. If, after 3 seconds, the DJI Phanton 3 

Professional UAs do not reacquire control link data from the GCS, the UAs will assume 

that the Control Link is lost and the UAs will return to the home position (i.e., failsafe 

mode) via GPS, and will descend to the takeoff position and shutdown. 

A complete description of the Failsafe Functions of the DJI Phanton 3 

Professional UAS are set forth at page 14 of the DJI Phanton 3 Professional User 

Manual, attached hereto as Exhibit B. 

iv. The DJI Phanton 3 Professional GCS And Its

Operation.

A complete description of the operation and specifications of the DJI Phanton 3 

Professional GCS and flight control software is provided at pages 35 through 39 of the 

DJI Phanton 3 Professional User Manual.
22

DJI Phanton 3 Professional User Manual is attached hereto as Exhibit B.

b. Flight Operations Of DJI Phanton 3 Professional UASs Are Limited To 

The Line Of Sight Of A Pilot in Command With A Safety Observer.

Ryan Joseph Cathey will only utilize pilots who have at least 20 hours flight time

to act as a pilot in command (PIC) of the DJI Phanton 3 Professional UASs. Additionally, 

a safety observer will assist all pilots during flight time. 

c. Flights Of DJI Phanton 3 Professional UASs Will Be Conducted 

Pursuant To Specific Operating Limitations.

In seeking this exemption, Ryan Joseph Cathey proposes to commercially 

operate DJI Phanton 3 Professional UASs for the special purpose of conducting aerial 

video and photography over certain areas of United States, pursuant to the following 

specific operating limitations:

1. Operations authorized by this grant of exemption will be limited to the following

aircraft described in the operating documents, rotorcraft UASs weighing less

than 55 pounds maximum gross weight: DJI Phanton 3 Professional Unmanned 

Aircraft Systems. Proposed operations of any other aircraft will require a new 

petition or a petition to amend this grant.

2. UAS operations under this exemption will be limited to conducting operations

for the purpose of aerial video and photography.

3. The UAs may not be flown at an indicated airspeed exceeding 20 knots.

4. The UA must be operated at an altitude of no more than 400 feet above ground

level (AGL), as indicated by the procedures specified in the operating

documents unless a special request is made and approved by ATC. All altitudes

reported to ATC must be in feet AGL.

5. The UAs must be operated within visual line of sight (VLOS) of the PIC at all

times. This requires the PIC to be able to use human vision unaided by any

device other than corrective lenses, as specified on the PIC’s FAA-issued airman

medical certificate.
23

6. The use of first person view (FPV) by the PIC or safety observer (SO) is not

permitted.

7. All operations must utilize a safety observer (SO). The SO may be used to satisfy

the VLOS requirement as long as the PIC always maintains VLOS capability.

The SO and PIC must be able to communicate verbally at all times. Electronic

messaging or texting is not permitted during flight operations. The PIC must be

designated before the flight and cannot transfer his or her designation for the

duration of the flight. The PIC must ensure that the SO can perform the

functions prescribed in the operating documents.

8. The SO must not perform any other duties beyond assisting the PIC with seeing

and avoiding other air traffic and other ground based obstacles/obstructions and

is not permitted to operate the camera or other instruments.

9. The operating documents and the grant of exemption must be accessible during

UAS operations and made available to the Administrator upon request. If a

discrepancy exists between the conditions and limitations contained in the grant

of exemption and the procedures outlined in the operating documents, the

conditions and limitations contained in the grant of exemption take precedence

and must be followed. Otherwise, the operator must follow the procedures as

outlined in its operating documents. The operator may update or revise its

operating documents. It is the operator’s responsibility to track such revisions

and present updated and revised documents to the Administrator upon request.

The operator must also present updated and revised documents if it petitions for

extension or amendment to the grant of exemption. If the operator determines

that any update or revision would affect the basis upon which the FAA granted

the exemption, then the operator must petition for amendment to its grant of

exemption. The FAA’s UAS Integration Office (AFS-80) may be contacted if

questions arise regarding updates or revisions to the operating documents.

10. Prior to each flight the PIC must inspect the UAS to ensure that it is in a

condition for safe flight. If the inspection reveals a condition that affects the

safe operation of the UAS, the aircraft is prohibited from operating until the

necessary maintenance has been performed and the UAS is found to be in a

condition for safe flight. The Ground Control Station must be included in the

preflight inspection. All maintenance and alterations must be properly

documented in the aircraft records.

11. Any UAS that has undergone maintenance or alterations that affect the UAS

operation or flight characteristics, e.g. replacement of a flight critical

component, must undergo a functional test flight. The PIC who conducts the

functional test flight must make an entry in the aircraft records.

12. The pre-flight inspection must account for all potential discrepancies, e.g.

inoperable components, items, or equipment, not already covered in the

relevant sections of the operating documents.
24

13. The operator must follow the UAS manufacturer’s aircraft/component,

maintenance, overhaul, replacement, inspection, and life limit requirements.

14. The operator must carry out its maintenance, inspections, and record keeping

requirements, in accordance with the operating documents. Maintenance,

inspection, alterations, and status of replacement/overhaul component parts

must be noted in the aircraft records, including total time in service, description

of work accomplished, and the signature of the authorized person returning the

UAS to service.

15. Each UASs operated under this exemption must comply with all manufacturer

Safety Bulletins.

16. The authorized person must make an entry in the aircraft record of the

corrective action taken against discrepancies discovered between inspections.

17. The PIC must have completed at least 25 hours of flight time.

18. The operator may not permit any PIC to operate unless the PIC meets the

operator’s qualification criteria and demonstrates the ability to safely operate

the UAS in a manner consistent with how the UAS will be operated under the

exemption, including evasive and emergency maneuvers and maintaining

appropriate distances from persons, vessels, vehicles and structures. PIC

qualification flight hours must be logged in a manner consistent with 14 C.F.R.

§ 61.51(b). Flights for the purposes of training the operator’s PICs are

permitted under the terms of the exemption. However, training operations may

only be conducted during dedicated training sessions. During training,

proficiency, and experience-building flights, all persons not essential for flight

operations are considered nonparticipants, and the PIC must operate the UA

with appropriate distance from nonparticipants in accordance with 14 C.F.R. §

91.119. 

19. UAS operations may not be conducted during night, as defined in 14 C.F.R. §

1.1. All operations must be conducted under visual meteorological conditions

(VMC). If flight at night is required, a special request will be made at the FAA

office closest to proposed area of operations. Flights under special visual flight

rules (SVFR) are not authorized.

20. The UA may not operate within 2 nautical miles of an airport reference point as

denoted on a current FAA-published aeronautical chart unless a letter of

agreement with that airport’s management is obtained, and the operation is

conducted in accordance with a NOTAM as required by the operator’s COA.

The letter of agreement with the airport management must be made available to

the Administrator upon request.
25

21. The UA may not be operated less than 400 feet below or less than 2,000 feet

horizontally from a cloud or when visibility is less than 3 statute miles from the

PIC.

22. If the UA loses communications or loses its GPS signal, it must return to a predetermined location within the planned operating area and land or be recovered

in accordance with the operating documents.

23. The PIC must abort the flight in the event of unpredicted obstacles or

emergencies in accordance with the operating documents.

24. The PIC is prohibited from beginning a flight unless (considering wind and

forecast weather conditions) there is enough power to fly at normal cruising

speed to the intended landing point and land the UA with 25% battery power

remaining.

25. The operator must obtain an Air Traffic Organization (ATO) issued Certificate

of Waiver or Authorization (COA) prior to conducting any operations under the

grant of exemption. This COA will also require the operator to request a Notice

to Airman (NOTAM) not more than 72 hours in advance, but not less than 48

hours prior to the operation. All operations shall be conducted in accordance

with airspace requirements in the ATO issued COA including class of airspace,

altitude level and potential transponder requirements.

26. All aircraft operated in accordance with the exemption must be identified by

serial number, registered in accordance with 14 C.F.R. part 47, and have

identification (N- Number) markings in accordance with 14 C.F.R. part 45,

Subpart C. Markings must be as large as practicable.

27. Before conducting operations, the radio frequency spectrum used for operation

and control of the UA must comply with the Federal Communications

Commission (FCC) or other appropriate government oversight agency

requirements.

28. The documents required fewer than 14 C.F.R. 91.9 and 91.203 must be

available to the PIC at the Ground Control Station of the UAS any time the

UAS is operating. These documents must be made available to the

Administrator or any law enforcement official upon request.

29. The UA must remain clear and yield the right of way to all manned aviation

operations and activities at all times.

30. The UAS may not be operated by the PIC from any moving device or vehicle.

31. Flight operations must be conducted at least 500 feet from all nonparticipating

persons (persons other than the PIC, SO, operator trainees or essential persons),

vessels, vehicles, and structures unless:
26

a. Barriers or structures are present that sufficiently protect nonparticipating

persons from the UA and/or debris in the event of an accident. The

operator must ensure that nonparticipating persons remain under such

protection. If a situation arises where nonparticipating persons leave such

protection and are within 500 feet of the UA, flight operations must cease

immediately and/or;

b. The aircraft is operated near vessels, vehicles or structures where the

owner/controller of such vessels, vehicles or structures has granted

permission and the PIC has made a safety assessment of the risk of

operating closer to those objects and determined that it does not present

an undue hazard, and;

c. Operations nearer to the PIC, SO, operator trainees or essential persons

do not present an undue hazard to those persons per § 91.119(a).

32. All operations shall be conducted over private or controlled-access property

with permission from the land owner/controller or authorized representative.

Permission from land owner/controller or authorized representative will be

obtained for each flight to be conducted.

33. Any incident, accident, or flight operation that transgresses the lateral or

vertical boundaries of the operational area as defined by the applicable COA

must be reported to the FAA's UAS Integration Office (AFS-80) within 24

hours. Accidents must be reported to the National Transportation Safety Board

(NTSB) per instructions contained on the NTSB Web site: www.ntsb.gov.

2. Reasons Why An Exemption From The Requirements Of Section 61.113(a)

And (b) Would Not Adversely Affect Safety.

Ryan Joseph Cathey submits that the equivalent level of safety established by 

Section 61.113(a) and (b) will be maintained because no PIC will be allowed to operate 

the DJI Phanton 3 Professional UASs unless that PIC has demonstrated, by meeting 

minimum flight-hour and currency requirements, that the PIC is able to safely operate 

the DJI Phanton 3 Professional UAS in a manner consistent with the exemption, 

including evasive and emergency maneuvers and maintaining appropriate distances from 

people, vessels, vehicles and structures. 

Considering Ryan Joseph Cathey's proposed area of operations, and the 

operating limitations set forth-above; the parallel nature of aeronautical knowledge 
27

requirements to those of commercial pilot requirements (See Exemption No. 11062); and 

the airmanship skills necessary to safely operate the DJI Phanton 3 Professional, Ryan 

Joseph Cathey submits that the additional manned airmanship experience of a 

commercially certificated pilot would not correlate to the airmanship skills necessary for 

Ryan Joseph Cathey's specific proposed flight operations. 

The FAA has previously granted relief from Section 61.113(a) and (b) specific to 

UAS, in circumstances similar, in all material respects, to those presented herein (e.g. 

Exemption Nos. 11062, 11063, 11064, 11065, 11066, 11067, 11080, 11109, 11110, 11112, 

11136, 11138, 11150, 11153, 11156, 11158, 11159, 11160, 11161). 

Ryan Joseph Cathey will not allow any PIC to operate the DJI Phanton 3 

Professional UAS unless that PIC has demonstrated, by meeting minimum flight-hour 

requirements or the DJI Phanton 3 Professional UAS training and currency requirements, 

that the PIC is able to safely operate the DJI Phanton 3 Professional UAS in a manner 

consistent with this exemption, including evasive and emergency maneuvers and 

maintaining appropriate distances from people, vessels, vehicles and structures. 

Specifically, the PIC must have accumulated and logged, in a manner consistent 

with 14 C.F.R. § 61.51(b), 25 hours of total time as a UAS rotorcraft pilot (with a 

minimum of 5 hours of those hours as a UAS pilot operating the same make and model of 

UAS to be used for operations under the exemption). In addition to the hour requirements, 

the PIC must accomplish 3 takeoffs and landings in the preceding 90 days (for currency

purposes). 
28

As in Exemption Nos. 11062, 11138, and 11153, prior documented flight 

experience that was obtained in compliance with applicable regulations will ensure an 

equivalent level of safety during Ryan Joseph Cathey's proposed operations. The 

Administrator has held that prior documented flight experience that was obtained in 

compliance with applicable regulations would ensure safe operations, stating as follows: 

In Exemption No. 11062, the FAA required that prior to conducting operations for 

the purpose of motion picture filming (or similar operations), the PIC must have 

accumulated and logged, in a manner consistent with 14 CFR 61.51(b), 25 hours of 

total time as a UAS rotorcraft pilot including at least 10 hours logged as a UAS 

pilot with a multi-rotor UAS. Prior to operations under Exemption No. 11062, the 

PIC must also have accumulated and logged a minimum of 5 hours as a UAS pilot 

operating the same make and model of UAS to be used for operations under the 

exemption. For clarification, the FAA considers these minimum hour requirements 

to be inclusive rather than additive; i.e. 5 hours make and model time may be 

included in the 10 hours of multi-rotor time and the 10 hours may be included in 

the total 25 hours of UAS rotorcraft time. In addition to the hour requirements, the 

PIC must accomplish 3 takeoffs and landings in the preceding 90 days (for 

currency purposes). The FAA finds that at a minimum, the flight-hour requirements 

in Exemption No. 11062 are appropriate to practice and build proficiency in the 

skills necessary to safely conduct the petitioner’s proposed operations. The FAA 

also finds that prior documented flight experience that was obtained in compliance 

with applicable regulations would satisfy this requirement. Training, proficiency, 

and experience-building flights can also be conducted under the grant of exemption 

to accomplish the required flight time. During training, proficiency, and 

experience-building flights the PIC is required to operate the UA with appropriate 

distances in accordance with 14 C.F.R 91.119. 

Exemption No. 11138 at page 15. 

Accordingly, Ryan Joseph Cathey will ensure safe operations by not allowing any PIC 

to operate the DJI Phanton 3 Professional UAS unless that PIC has 

demonstrated, by meeting minimum flight-hour and currency requirements, that the PIC is 

able to safely operate the DJI Phanton 3 Professional UAS in a manner 

consistent with the exemption, including evasive and emergency maneuvers and 

maintaining appropriate distances from people, vessels, vehicles and structures. 
29

3. Reasons Why An Exemption From The Requirements Of Section 91.7(a)

Would Not Adversely Affect Safety.

The equivalent level of safety established by Section 91.7(a) will be maintained 

because prior to every flight, Ryan Joseph Cathey will ensure that the DJI Phanton 3 

Professional UAS is in an airworthy condition based upon the UAS’s compliance with its 

operating documents and as stated in the conditions and limitations herein. Additionally, 

the FAA has previously granted relief from Section 91.7(a) specific to UAS, in 

circumstances similar, in all material respects, to those presented herein (e.g. Exemption 

Nos. 11062, 11063, 11064, 11065, 11066, 11067, 11080, 11109, 11110, 11112, 11136, 

11138, 11150, 11153, 11156, 11157, 11158, 11159, 11160, 11161). 

4. Reasons Why An Exemption From The Requirements Of Section 91.121

Would Not Adversely Affect Safety.

The equivalent level of safety established by Section 91.121 will be maintained 

because the altitude information of the DJI Phanton 3 Professional UAs will be provided 

to the PIC via GPS equipment and a radio communications telemetry data link, which

downlinks from the UA to the GCS for active monitoring of the flight path and altitude. 

This altitude information, combined with Ryan Joseph Cathey's operation of the DJI 

Phanton 3 Professional UAs within visual line of sight, at or below 400 feet AGL, will 

ensure a level of safety equivalent to Section 91.121. The altitude information will be 

generated by GPS equipment installed onboard the aircraft. Prior to each flight, a zero 

altitude initiation point is automatically established by the UASs at ground level. 

The FAA has previously granted relief from Section 91.121 specific to UAS, in 

circumstances similar, in all material respects, to those presented herein (e.g. Exemption 

Nos. 11062, 11063, 11064, 11065, 11066, 11067, 11080, 11109, 11112, 11136, 11138, 

11150, 11153, 11156, 11157, 11158, 11159, 11160, 11161). 
30

5. Reasons Why An Exemption From The Requirements Of Section 91.151(b)

Would Not Adversely Affect Safety.

A grant of this exemption would ensure an equivalent level of safety established by 

14 C.F.R. Section 91.151(b) as a result of (1) the technical specifications of the DJI 

Phanton 3 Professional UASs; (2) the limitations on the proposed flight operations; and 

(3) the location of the proposed flight operations. Accordingly, Ryan Joseph Cathey will 

ensure that it will safely operate the battery powered DJI Phanton 3 Professional UAs 

during daylight hours in VFR conditions, with enough battery power to fly for a total 

duration of 13.5 minutes to the first point of intended landing and, assuming normal 

cruising speed, to fly after that for at least 4.5 minutes. 

Here, as in Exemption No. 11109, the technical specifications of the DJI Phanton 3 

Professional UASs; the limitations on the proposed flight operations; and the location of

the proposed operations, will ensure an equivalent level of safety established by 14 C.F.R. 

Section 91.151(b). Furthermore, safety will be ensured as the DJI Phanton 3 Professional 

UASs provide audible and visual warnings to the PIC at the GCS when the UAs 

experiences low battery voltage, the first warning occurring at approximately 33% 

remaining battery power, and again at approximately 10% remaining battery power. At the 

critically low battery level, the DJI Phantom 3 Professional UASs will descend and land 

automatically. 

Significantly, previous exemptions granted by the FAA concerning Section 91.151 

establish that safety is not adversely affected when the technical characteristics and 

operating limitations of the UAS are considered. Relief has been granted for manned 

aircraft to operate at less than the minimums prescribed in Section 91.151, including 

Exemption Nos. 2689, 5745, and 10650. Moreover, the FAA has previously granted relief 
31

from Section 91.151 specific to UAS, in circumstances similar, in all material respects, to 

those presented herein (e.g. Exemption Nos. 8811, 10808, 10673, 11042, 11062, 11063, 

11064, 11065, 11066, 11067, 11080, 11109, 11110, 11136, 11138, 11150, 11153, 11156, 

11157, 11158, 11159, 11160, 11161). 

6. Reasons Why An Exemption From The Requirements Of Sections

91.405(a), 91.407(a)(1), 91.409(a)(1) & (a)(2), And 91.417(a) & (b) Would

Not Adversely Affect Safety.

In seeking this exemption, Ryan Joseph Cathey submits that the equivalent level of 

safety with regard to the regulatory maintenance and alteration requirements established 

by Sections 91.405(a), 91.407(a)(1), 91.409(a)(1) & (a)(2), and 91.417(a) & (b) will be 

met because Ryan Joseph Cathey will use trained technicians to perform maintenance, 

alterations, or preventive maintenance on the UASs using the methods, techniques, and 

practices prescribed in the operating documents (i.e., the Ryan Joseph Cathey Aerial 

Operations Manual, Monthly Maintenance Log, and DJI Phanton 3 Professional

Instruction Manual). Furthermore, Ryan Joseph Cathey will document and maintain all 

maintenance records for the DJI Phanton 3 Professional UASs. 

Since the DJI Phanton 3 Professional UASs will be inspected as prescribed by the 

operating documents, Ryan Joseph Cathey will maintain the equivalent level of safety 

established by Sections 91.405(a), 91.409(a)(1), and 91.409(a)(2). A copy of the DJI 

Phanton 3 Professional User Manual is attached hereto as Exhibit B; a copy of the DJI 

Phanton 3 Professional UAS Maintenance LOG is attached hereto as Exhibit C. 

Likewise, the exemption sought will not adversely affect safety because Ryan 

Joseph Cathey will use trained technicians to perform maintenance, alterations or 

preventive 
32

maintenance on the UAS using the methods, techniques, and practices prescribed by the 

operating documents. 

Furthermore, the exemption sought would maintain an equivalent level of safety 

established by Sections 91.407, 91.417(a) and 91.417(b), because all maintenance of the 

DJI Phanton 3 Professional UASs will be performed by trained technicians. Maintenance 

will be documented and maintained utilizing the monthly maintenance log. 

Significantly, previous exemptions granted by the FAA concerning Sections 

91.405(a), 91.407(a)(1), 91.409(a)(1) & (a)(2), and 91.417(a) & (b) establish that safety is 

not adversely affected when the technical characteristics and operating limitations of the 

UAS are considered. 

In consideration of Ryan Joseph Cathey's proposed operating limitations, the 

operating documents, and the technical aspects of the DJI Phanton 3 Professional UASs, 

Ryan Joseph Cathey submits that safety will not be adversely affected by granting 

exemption from 14 C.F.R. Sections 91.405(a), 91.407(a)(1) and (a)(2), 91.409(a)(2), and 

91.417(a) and (b). The FAA has previously granted relief specific to UAS in circumstances 

similar, in all material respects, to those presented herein (e.g. Exemption Nos. 11062, 

11063, 11064, 11065, 11066, 11067, 11080, 11109, 11110, 11112, 11136, 11138, 11150, 

11153, 11156, 11157, 11158, 11159, 11160, 11161). 

7. The FAA May Prescribe Any Other Conditions For Safe Operation.

In accordance with Section 333 of the FAA Modernization and Reform Act of 2012 

(FMRA) and 14 C.F.R. § 21.16 entitled Special Conditions, Ryan Joseph Cathey requests 

that the FAA prescribe special conditions for the intended operation of the DJI Phanton 3 

Professional UASs, which contain such safety standards that the 
33

Administrator finds necessary to establish a level of safety equivalent to that established by 

14 C.F.R. Part 21, Subpart H, and 14 C.F.R §§ 61.113(a) & (b), 91.7 (a), 91.121, 

91.151(b), 91.405(a), 91.407(a)(1), 91.409(a)(1) & (a)(2), and 91.417(a) & (b). Such 

special conditions will permit safe operation of the UAs for the limited purpose of 

conducting aerial video and photography over certain areas of the United States for 

compensation or hire. FMRA Section 333 sets forth the requirements for considering 

whether a UAS will create a hazard to users of the NAS or the public, or otherwise pose a 

threat to national security; and further, provides the authority for such UAS to operate 

without airworthiness certification in accordance with any requirements that must be 

established for the safe operation of the UAS in the NAS. 

Likewise, the Administrator may prescribe special conditions pursuant to 14 C.F.R.

§ 21.16, for operation of the DJI Phanton 3 Professional UASs, since the

airworthiness regulations of 14 C.F.R. Part 21 do not contain adequate or appropriate 

safety standards, due to the novel or unusual design features of the aircraft. Section 21.16, 

entitled Special Conditions, states the following: 

If the FAA finds that the airworthiness regulations of this subchapter do not contain 

adequate or appropriate safety standards for an aircraft, aircraft engine, or propeller 

because of a novel or unusual design feature of the aircraft, aircraft engine or 

propeller, he prescribes special conditions and amendments thereto for the product. 

The special conditions are issued in accordance with Part 11 of this chapter and 

contain such safety standards for the aircraft, aircraft engine or propeller as the 

FAA finds necessary to establish a level of safety equivalent to that established in 

the regulations. 

See 14 C.F.R. § 21.16.

Therefore, in accordance with FMRA Section 333 and 14 C.F.R. § 21.16, the FAA 

may prescribe special conditions for Ryan Joseph Cathey’s intended operation of the DJI 

Phantom 3 Professional UASs, which contain such safety standards that the 
34

Administrator finds necessary to establish a level of safety equivalent to that established by 

14 C.F.R. Part 21, Subpart H, and 14 C.F.R Sections 61.113(a) & (b), 91.7(a), 91.121, 

91.151(b), 91.405(a), 91.407(a)(1), 91.409(a)(1) & (a)(2), and 91.417(a) & (b).

F. A Summary That Can Be Published In The Federal Register, stating: The Rules 

From Which Ryan Joseph Cathey Seeks Exemption: 

Ryan Joseph Cathey seeks exemption from the requirements of 14 C.F.R Sections 

61.113(a)&(b), 91.7(a), 91.121, 91.151(b), 91.405(a), 91.407(a)(1), 91.409(a)(1) & 

(a)(2), and 91.417(a) & (b). 

A Brief Description Of The Nature Of The Exemption Ryan Joseph 

Cathey Seeks: 

This exemption will permit Ryan Joseph Cathey to commercially operate an 

Unmanned Aircraft System (UAS) for the purpose of conducting aerial video and
