Dear Sir or Madam:

This petition is being submitted on my behalf without legal counsel or consulting services.

Pursuant to Section 333 of the FAA Modernization and Reform Act of 2012 (FMRA), Section 333, Special Rules for Certain Unmanned Aircraft Systems, and 14 C.F.R. Part 11, Kenneth J. Crawford (sole owner and operator of EyFly Visualization Systems), a start

- up freelance, Disabl ed Veteran

- Owned & Operated, multimedia, visualization, terra and aerial imagery small business company, hereby petitions the Administrator to permit me to commercially operate the DJI Phantom 2, & 3 Series and the DJI Inspire

- 1 sUASs in the National Airsp ace System (NAS), and for an exemption from the six 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).

This exemption will allow operation of my Small Unmanned Air craft System (sUAS) commercially in airspace regulated by the Federal Aviation Administration (FAA) so long as I conduct such operations with and under the conditions outlined herein or as may be established by the FAA as required by Section 333.

The reque sted exemption would permit Kenneth J. Crawford (on behalf of EyFly Visualization Systems) to pursue my commercial interests in providing services to clients using a sUAV within the limits granted in the following

areas:

1. Adventure recreation activities ( mountain and road biking, enduro motorcycling, boating, skiing, hiking, climbing, etc.

- operated a minimum of 500’ lateral distance from persons )

2. Real Estate Documentation and Marketing

3. Land Management (in support of farming, ranch operations, and hunting leases)

4. Land Surveying

5. Geographic Referencing

6. Rooftop imaging and documentation for insurance purposes.

7. Post Disaster Damage Assessments and Documentation

### 2 

### 8. Special Events (i.e. city & community sponsored recreation events such as MS Walk, Relay for Life C ancer Walks, seasonal events, birthday parties, family reunions, etc.

- operated a minimum of 500’ lateral distance from persons )

EyFly Visualization Systems states that all sUAS flights will occur over private or controlled access property and will do so with the property owner's consent and knowledge and that only people who have consented or otherwise have agreed to be within the sUAS’ radius during filming and photography applications.

I, Kenneth J. Crawford, have demonstrated the ability to safely and

effective ly fly the DJI Phantom Series 2, & 3 systems and the DJI Inspire

- 1, which I request authorization to use for all commercial and private purposes. EyFly Visualization will comply with local ordinances and laws regarding the operation of sUAS, and shall adhere to all weather and environmental restrictions or limitations in reference to the operations of

sUAS.

All flights will comply with federal, state, and local laws or ordinances regarding privacy.

I (as the sole owner and operator of EyFly Visual ization Systems) am seeking the exemption as I am committed to complying with all of the rules, guidelines, limitations, and future legislation set forth by the FAA. I agree to and will operate the sUAS in the manner and for the purpose

described. Withou t the exemption request granted, I will not be to operate my Disabled Veteran

- owned small business. As stated in the Notice of Proposed Rulemaking Evaluation for Small Unmanned Aircraft Systems (sUAS) “drones pose a low level of pubic risk and that imposi ng all
of those requirements would be unduly burdensome. As an owner

- operator I respectfully request the location in which I may have the opportunity to take the proposed aeronautical knowledge test in order to obtain an unmanned aircraft operator certi ficate.

In consideration of the speed, weight, size, and limited operating area associated with the sUAS and its operation, my operations meets the conditions of FMRA Section 333 and therefore, should not require an

airworthiness certificate in accordance with 14 C.F.R. Part 21, Subpart H. Accordingly, I request 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.

### 3 

### I will document and maintain all maintenance records for the DJI

Phantom 2, & 3 systems and for the DJI Inspire

- 1 sUASs. Relief from certain requirements of Section 61.113(a) and (b), entitled Sport pilot privileges

and limitations: Pilot in c ommand, is requested by Kenneth J. Crawford (EyFly Visualization Systems) to the extent necessary to allow me to serve as a Pilot in Command (PIC) as demonstrated, by meeting air knowledge and skills requirements for small UAV platforms and having safely

c onducted over 100 hours of recreational flights over the past eighteen

months with no mishaps . As the sole owner and operator, I will operate the sUAS in a manner consistent with this exemption, including evasive and emergency maneuvers and maintaining ap propriate distances from people, vessels, vehicles and structures.

Kenneth J. Crawford Seeks The Relief

.
a. Extent Of Relief Kenneth J. Crawford Seeks And The Reason

Kenneth J. Crawford Seeks Relief From Section 61.113(a) And (b).

i. Relief from Section 61.113(a) and (b) entitled Sport pilot privileges and limitations: Pilot in command , is requested to

the extent necessary to allow a PIC holding a sport pilot or higher level certificate, as well as a current and valid
airman medical certificate, and who has met certain flight

- hour and currency requirements, to conduct the proposed UAS flight operations for compen sation or hire. (continued from previous page)

d. The current inspection status of the aircraft, including the time since the last inspection required by the inspection program under which the aircraft and its appliances are maintained.

e. The current status of applicable airworthiness directives (AD) and safety directives including, for each, the method of compliance, the AD or safety

directive number and revision date. If the AD or safety directive involves recurring action, the time and date when the next action is required.

f. Copies of the forms prescribed by § 43.9(d) of this chapter for each major alteration to the airframe and currently installed engines, rotors, propellers, and appliances.

viii. The owner or operator shall retain the following records for the periods prescribed:

1. The records specified in paragraph (a)(1) of this section shall be retained until the work is repeated or superseded by other work or for 1 year after the work is performed.

2. The records specified in paragraph (a)(2) of this section

shall be retained and transferred with the aircraft at the

time the aircraft is sold.

3. A list of defects furnished to a registered owner or operator under § 43.11 of this chapter shall be retained until the defects are repaired and the aircraft is approved for return to service.

### 8 

### ii. This relief is requested since the limitations set forth in
Section 61.113(a) and (b) state that a sport pilot may, for compensation or hire, act as PIC of an aircraft in connection with any business or employment if: (1) The flight is on ly incidental to that business or employment;

and (2) The aircraft does not carry passengers or property for compensation or hire.

iii. As set forth more fully below, Kenneth J. Crawford submits

that an equivalent level of safety will be maintained

because no PIC will be allowed to operate the DJI

Phantom 2 & 3 UAS or DJI Inspire UAS unless that PIC has met certain flight

- hour and currency requirements, demonstrating that the PIC is able to safely operate either

the DJI Phantom 2 & 3 or DJI Inspire UAS in a man ner 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.

iv. Further, Kenneth J. Crawford subm its th at all flights of the

DJI Phantom 2 & 3 and DJI Inspire UASs, conducted by the PIC pursuant to the grant of this Petition: (1) will be 13

incidental to Kenneth J. Crawford ’s business; and (2) will not carry passengers or property for compensation or hire.

b. Extent Of Relief Kenneth J. Crawford Seeks And The Reason
Kenneth J. Crawford Seeks Relief From Section 91.7(a).

i. Relief from Section 91.7(a) entitled Civil aircraft
airworthiness, is requested to the extent required to allow
Kenneth J. Crawford to determi ne that t he DJI Phantom 2

& 3 and DJI Inspire UASs are in airworthy condition prior to every flight by ensuring that the UAS is in compliance with

the operating documents (i.e., the Aerial Operations Manual, Monthly Maintenance Log, and DJI Phantom 2 &

3 a nd DJI Inspire Instruction Manual).

ii. Kenneth J. Crawford seeks the requested relief because

the DJI Phantom 2 & 3 and DJI Inspire UASs do not require

an airworthiness certificate in accordance with 14 C.F.R. Part 21, Subpart H. Therefore, Kenneth J. Crawfo rd will

ensure that the DJI Phantom 2 & 3 and DJI Inspire UASs are

in airworthy condition based upon its compliance with the operating documents (i.e., Monthly Maintenance Log,

and DJI Phantom 2 & 3 and DJI Inspire Instruction Manual) prior to every flight , and further, determine that the aircraft are in condition for safe flight, as stated in the conditions

and limitations below.

### 9 

### c. Extent Of Relief Kenneth J. Crawford Seeks And The Reason
Kenneth J. Crawford Seeks Relief From Section 91.121.

i. Relief from Sec tion 91.121, entitled Altimeter settings, may be required to allow flight operations of the DJI Phantom 2

& 3 and DJI Inspire UASs, which utilize a barometric pressure sensor, GPS equipment, and a radio communications telemetry data link to downlink altitu de
information from the UAS to the PIC at the ground control station (GCS).

ii. Since the FAA requires that any altitude information concerning UAS operations be reported to air traffic control (ATC) in feet above ground level (AGL), Kenneth J.

Crawford seeks the requested relief because the DJI

Phantom 2 & 3 and DJI Inspire UAS’s altimeter may be set on the ground to zero feet AGL, rather than the local barometric pressure or field altitude, before each flight.

iii. 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.

iv. As more fully set forth herein, an equivalent level of safety

will be maintained since the DJI Phantom 2 & 3 an d DJI Inspire UASs 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 UAS on the heads

- up display of the

GCS.

d. Extent Of Relief Kenneth J. Crawford Seeks And The Reason
Kenneth J. Crawford Seeks Relief From Section 91.151(b).

i. Relief from Section 91.151(b) entitled Fuel requirements for flight in VFR conditions, is requested to the ext ent required to allow flights of the battery powered DJI Phantom 2 & 3 and DJI Inspire UASs during daylight hours in visual meteorological conditions (VMC), under visual flight rules (VFR), for a total duration of 15 minutes to the first point of

intended landing and, assuming normal cruising speed, to fly after that for at least 5 minutes.

ii. Kenneth J. Crawford seeks the requested relief because without an exemption from Section 91.151(b), the flight

time duration of t he battery powered DJI Phantom 2 & 3

an d DJI Inspire UASs will severely constrain the practicality of any aerial video or still photo flight operations that

### 10 

### Kenneth J. Crawford proposes to conduct pursuant to this

Petition.

iii. Significantly, as set forth below, the technical specifications of the DJI Phantom 2 & 3 and DJI Inspire
UASs, the DJI Phantom 2 & 3 and DJI Inspire operating
documents, and Kenneth J. Crawford ’s proposed operating limitations, ensure that Kenneth J. Crawford will safely operate the battery powered DJI Phantom 2 & 3

and DJI Inspire UASs during daylight hours in visual meteorological conditions (VMC), under visual flight rules ( VFR), with enough battery power to fly for a total duration
of 15 minutes to the first point of inten ded landing and, assuming normal cruising speed, t o fly after that for at least
5 minutes.

e. Extent Of Relief Kenneth J. Crawford Seeks And The Reason

Kenneth J. Crawford Seeks Relief From Sections 91.405(a), 91.407(a)(1), 91.409(a) (1) & (a)(2), And 91.417(a) & (b).

i. 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, Kenneth J. Crawford requests
relief from these Sections because the DJI Phantom 2 & 3 and DJI Inspire UASs do not require airworthiness

certificates.

ii. As s et forth more fully below, the DJI Phantom 2 & 3 and

DJI Inspire UASs meet the conditions of FMRA Section 333 for operation without an airworthiness certificate.

iii. Accordingly, Kenneth J. Crawford will use trained or manufacture recognized technicians to pe rform maintenance, alterations, or preventive maintenance on the UASs using the methods, techniques, and practices prescribed in the UAS operating documents (i.e., the Monthly Maintenance Log, and DJI Phantom 2 & 3 and DJI Inspire Instruction Manuals).

iv. Fu rthermore, Kenneth J. Crawford will document and

maintain all maintenance records for the DJI Phantom 2 &

3 and DJI Inspire UASs.

4. The Reasons Why Granting Kenneth J. Crawford ’s Request Would Be I n The Public Interest; That Is, How It Would Benefit The Publ ic As A Whole.

a. Granting the present Petition will further the public interest by allowing Kenneth J. Crawford to safely, efficiently, and economically perform aerial video and photography of Real
Estate, Vacant Land, subdivisions, and Industrial property o ver cert ain areas of the United States, Search and Rescue deployment , and disaster survey.

### 11 

### b. Additionally, use of the DJI Phantom 2 & 3 and DJI Inspire UASs

will decrease congestion of the NAS, reduce pollution, and provide significant benefits to the econ omy.

c. Notably, the benefits of Kenneth J. Crawford’s proposed operation of the DJI Phantom 2 & 3 and DJI Inspire UASs will be realized without implicating any privacy issues.

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

The DJI Phantom 2 & 3 and DJI Inspire UASs 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

Phantom 2 & 3 or DJI Inspire 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.

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

Phantom 2 & 3 and DJI Inspire UASs. Conducting aerial acquisitions with the DJI Phantom 2 & 3 and DJI Inspire UASs, instead of manned aircraft, will greatly benefit the public by drastically reducing the s ubstantial risk to life and property in the

air and on the ground, which is usually associated with

traditional manned aircraft flight operations. Aside from the lack of flight crew members located onboard the aircraft, the DJI

Phantom 2 & 3 and DJI Inspir e UASs (weighing approximately 2 pounds 11 ounces and 6 pounds 7.5 ounces respectively, at their maximum gross weights with lengths of 16 inches and 17.3 inches respectively, with widths of 16 inches and 17.7 inches respectively, 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 4,450 pounds with a wingspan of approximately 37 feet, a length of 42 feet, and a fuel capacity of 110 gallons, (these are the

s pecifications of a Bell Jet Ranger 206)).

f. Performing Aerial Video and Photography Operations With The

DJI Phantom 2 & 3 and DJI Inspire UASs Will Benefit The Economy.

In addition to being safe and efficient, the DJI Phantom 2 & 3

and DJI Inspire UASs are also an economical alternative to using

manned aircraft to conduct similar aerial operations. As such, operation of the DJI Phantom 2 & 3 and DJI Inspire UASs will allow
United State s citizens, like Kenneth J. Crawford , to remain competitive and contribute to growth of the U.S. economy. Specifically, with the housing sector, operating the battery

### 12 

### powered DJI Phantom 2 & 3 and DJI Inspire UASs is one such technology that not only allow s citizens such as Kenneth J.

Crawford to remain competitive and profitable, and therefore, provide greater exposure and marketing of said real property, which will ultimately contribute to growth of the U.S. economy housing sector.

g. No Privacy Issues. Sim ilar to the manned aerial acquisition flight operations that have been conducted for decades, Kenneth J.
Crawford ’s proposed operation of the DJI Phantom 2 & 3 and DJI Inspire UASs will not implicate any privacy issues. Specifically,

the DJI Phantom 2 & 3 and DJI Inspire UASs will be operated only in compliance with operating documents (i.e., DJI Phantom 2 &

3 and DJI Inspire Instruction Manual ), which requires property
owner involvement, and in accordance with the Federal Aviation Regulations, including t he minimum altitude requirements of 14 C.F.R. § 91.119.

5. 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 Kenneth J. Crawfor d Seeks Exemption.

a. Reasons Why The DJI Phantom 2 & 3 and DJI Inspire UASs Meet
The Conditions Of The FAA Modernization and Reform Act of

2012 (FMRA) Section 333.

i. In consideration of the size, weight, speed, and limited operating area associated with the un manned aircraft and its operation, Kenneth J. Crawford ’s operation of the

DJI Phantom 2 & 3 and DJI Inspire 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. Sec tion 333 that p rovides 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.

### 13 

### ii. S pecifically, 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 det ermine 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. (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 airw orthiness 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 tha t 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.

### 14 

### b. In seeking this exemption, Kenneth J. Crawford submits that the

DJI Phantom 2 & 3 and DJI Inspire UASs can operate safely in the NAS pursuant to FMRA Section 333, as demonstrated by:

i. the chara cteristics of the DJI Phantom 2 & 3 and DJI Inspire

UASs

ii. the pilot certification requirement

iii. the specific operating limitations.

c. The Specifications Of The DJI Phantom 2 & 3 and DJI Inspire UASs
Demonstrate Its Safe Characteristics.

i. The DJI Phantom 2 & 3 an d DJI Inspire 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.

1. Technical Specifications Of The DJI Phantom 2 & 3 and DJI Inspire UASs are set forth by the DJI Phantom

2 & 3 and DJI Inspire Specifications and Data Sheet,
attached hereto as Exhibit A and B.

2. The DJI Phantom 2 & 3 and DJI Inspire UASs Autonomous Flight And Navigation Modes Enable

The UASs To Remain Within A Defined Oper ational

Area. The DJI Phantom 2 & 3 and DJI Inspire UASs may be operated in both manual and fully autonomous flight modes. A complete description

of the flight and navigational modes of the DJI

Phantom 2 & 3 and DJI Inspire UASs is provided in

the DJI Pha ntom 2 & 3 and the DJI Inspire User
Manuals, attached hereto as Exhibit C and D.

3. The DJI Phantom 2 & 3 and DJI Inspire UASs a re d esigned f or a utomatic r eturn t o h ome p oint o r h over i n t he e vent o f l oss o f t he c ontrol l ink o r

n avigation. When the Control L ink is lost, the DJI

Phantom 2 & 3 and DJI Inspire UASs will remain stationary, in flight, for 3 seconds or more. If, after 3
seconds, the DJI Phantom 2 & 3 and DJI Inspire UASs do not reacquire control link data from the GCS, the

UASs will assume that th e Control Link is lost and the UASs 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 Phantom 2 & 3 UAS and the DJI Inspire Us er Manuals respectively, can be found at the referenced links at the end of this

document

.

### 15 

### 4. The DJI Phantom 2 & 3 and DJI Inspire Safety Zones.

a. A recent firmware update provides Safety Zones whereby restrictions are self

- imposed by
the software in the UA S. The restricted areas

are divided into Category A, and Category B. Category A is around larger airports like DFW
and Love Field. Within 1.5 miles of this zone,

the UAS will not take off. Between 1.5 miles
and 5 miles, the maximum altitude is 35 feet. If flying within 320 feet this safety zone, a warning message will appear on the DJI Vision

app. Category B safety zone is around smaller airports. Within .6 miles of this zone, the UAS will not take off. If flying within .6 miles this safety zone, a warning message will appear on the DJI Vision application.

b. A complete description of the “Flight

Restriction of Restricted Areas” of the DJI

Phantom 2 & 3 and DJI Inspire GCS and flight control software is provided the DJI Phantom

2 & 3 User Manual and the DJI Ins pire User

revise its operating documents. It is the operator’s responsibility to track such r evisions and present updated and revised documents

to the Administrator upon request. The operator mu st 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 mu st 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.

k. Prior to each flight the PIC must inspect the
UAS to ensure that i t 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 fo r 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.

### 18 

### l. Any UAS that has undergone maintenance or

alterations that affect the UAS operati on 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.

### 19 

### s. 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

consisten t 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

wi th 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 exper ience

building flights, all persons not essential for flight operations are considered nonparticipants, and the PIC must operate

the UAS with appropriate distance from nonparticipants in accordance with 14 C.F.R. § 91.119.

t. UAS operations may not be conduct ed 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.

u. The UAS may not operate within 5 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.

v. The UAS may not be operated less than 50 0
feet below or less than 2,000 feet horizontally from a cloud or when visibility is less than 3
statute miles from the PIC.

### 20 

### w. If the UAS loses communications or loses its GPS signal, it must return to a pre

- determined location within the planned operating area and land or be recovered in accordance with the operating documents.

x. The PIC must abort the flight in the event of unpredicted obstacles or emergencies in accordance with the operating documents.

y. The PIC is prohibited from beginning a flight unless (c onsidering wind and forecast weather conditions) there is enough power to fly at normal cruising speed to the intended landing point and land the UAS with 25% battery power remaining.

z. The operator must obtain an Air Traffic Organization (ATO) issued Certif icate 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.

aa. 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.

bb. Before conducting operations, the radio

fr equency spectrum used for operation and control of the UAS must comply with the

Federal Communications Commission (FCC) or other appropriate government oversight agency requirements.

### 21 

### cc. The documents required fewer than 14

C.F.R. 91.9 and 91.203 must be ava ilable 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.

dd. The UAS must remain clear and yield the right of way to all manned aviation operations

and activities at all times.

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

ff. Flight operations must be conducted at least
500 feet from all nonparticipating persons (persons other than the PIC, SO, opera tor trainees or essential persons), vessels, vehicles,

and structures unless:
i. Barriers or structures are present that sufficiently protect nonparticipating persons from the UAS and/or debris in

the event of an accident. The operator must ensure that nonpar ticipating persons remain under such protection. If

a situation arises where nonparticipating persons leave such protection and are within 500 feet of the UAS, flight operations must cease immediately and/or;

ii. 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;
iii. Operations nearer to the PIC, SO, operator trainees or essential persons do not present an undue hazard to those persons per § 91.119(a).

### 22 

### gg. All operations shall be conducted over sport or controlled

- access property with permission from the land owner/cont roller or
authorized representative. Permission from land owner/controller or authorized representative will be obtained for each flight

to be conducted.

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

boundaries of th e operational area as defined by the applicable COA must be reported to the FAA's UAS Integration Office (AFS

- 80) within 24 hours.

ii. Accidents must be reported to the National Transportation Safety Board (NTSB) per

instructions contained on the NTSB Web sit e: www.ntsb.gov.
ii. Reasons Why An Exemption From The Requirements Of
Section 61.113(a) And (b) Would Not Adversely Affect Safety.

1. Kenneth J. Crawford submits that the equivalent level of safety established by Section 61.113(a) and (b) will be maintained bec ause no PIC will be allowed to operate the DJI Phantom 2 & 3 and DJI Inspire UASs unless that PIC has demonstrated, by meeting minimum UAS flight

- knowledge and skills requirements, that the PIC is able to safely operate

the DJI Phantom 2 & 3 or DJI Inspire UASs in a manner consistent with the exemption, including evasive and emergency maneuvers and maintaining appropriate distances from people,
vessels, vehicles and structures.

2. Considering Kenneth J. Crawford ’s proposed area of operations, and the operatin g limitations set forth

above; the parallel nature of sport pilot aeronautical knowledge requirements to those of commercial pilot requirements (See Exemption No. 11062); and the airmanship skills necessary to safely operate the

DJI Phantom 2 & 3 or DJI I nspire UAS, Kenneth J.
Crawford submits that the additional manned airmanship experience of a commercially certificated pilot would not correlate to the airmanship skills necessary for Kenneth J. Crawford ’s specific proposed micro UAS or small UAS flight

### 23 

### o perations. 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,

111 10, 11112, 11136, 11138, 11150, 11153, 11156, 11158, 11159, 11160, 11161).

3. Kenneth J. Crawford will not allow any PIC to operate the DJI Phantom 2 & 3 or DJI Inspire UAS unless that PIC has demonstrated, by meeting minimum flight

- hour requirements or the D JI

Phantom 2 & 3 or DJI Inspire UAS training and currency requirements, that the PIC is able to safely operate the DJI Phantom 2 & 3 or DJI Inspire UAS in a

manner consistent with this exemption, including evasive and emergency maneuvers and maintaining ap propriate 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 tho se 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).

4. 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 Kenneth J.
Crawford’s proposed operations. The Administrator

has held t hat 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 pic ture 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

### 24 

### 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 mini mum 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.

5. In addition to the hour require ments, 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 ne cessary 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

bui lding 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 UAS

with appropriate distances in a ccordance with 14

C .F.R 91.119 Exemption No. 11138 at page 15.

6. Accordingly, Kenneth J. Crawford will ensure safe operations by not allowing any PIC to operate the

DJI Phantom 2 & 3 or DJI Inspire UAS unless that PIC has demonstrated, by meeting minimum flight

- hour

and cur rency requirements, that the PIC is able to safely operate the DJI Phantom 2 & 3 or DJI Inspire UAS in a manner consistent with the exemption, including evasive and emergency maneuvers and maintaining appropriate distances from people,
vessels, vehicles an d structures.

iii. 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, Kenneth J.
Crawford will ens ure that the DJI Phantom 2 & 3 or DJI Inspire 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

### 25 

### Se ction 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).

iv. 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

Phantom 2 & 3 an d DJI Inspire UASs will be provided to the PIC via GPS equipment and a radio communications telemetry data link, which downlinks from the UAS to the GCS for active monitoring of the flight path and altitude.
This altitude information, combined with Kennet h J.
Crawford ’s operation of the DJI Phantom 2 & 3 and DJI Inspire UASs within visual line of sight, at or below 500 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 re spects, 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).

v. 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 Phantom

2 & 3 and DJI Inspire UASs; (2) the limi tations on the proposed flight operations; and (3) the location of the proposed flight operations.

1. Accordingly, Kenneth J. Crawford will ensure that it will safely operate the battery powered DJI

Phantom 2 & 3 and DJI Inspire UASs during daylight

hours in VFR conditions, with enough battery power to fly for a total duration of 15 minutes to the first point of intended landing and, assuming normal cruising speed, to fly after that for at least 5 minutes.

2. Here, as in Exemption No. 11109, the technical

spec ifications of the DJI Phantom 2 & 3 and DJI

### 26 

### Inspire 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, sa fety will be ensured as the DJI

Phantom 2 & 3 and DJI Inspire UASs provide audible and visual warnings to the PIC at the GCS when the UASs 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 Vision+ and DJI Inspire 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.

3. Relief has been granted for manned aircraft to operate at less than the minimums prescribed in Section 91.151, including Exempti on Nos. 2689, 5745, and 10650. Moreover, the FAA has previously granted relief 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).

vi. 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.

1. In seeking this exemption, Kenneth J. Crawford 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 Kenneth J.

Crawford 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 Aerial Operations

### 27 

### Manual, Monthly Maintenance Log, and DJI

Phantom 2 & 3 and DJI Inspire Instruction Manual).

2. Furthermore, Kenneth J. Crawford will document
and maintain all maintenance records for the DJI

Phantom 2 & 3 and DJI Inspire UASs. Sinc e the DJI

Phantom 2 & 3 and DJI Inspire UASs will be inspected

as prescribed by the operating documents, Kenneth
J. Crawford 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

P hantom 2 & 3 and DJI Inspire User Manual links are provided at the end of this document for reference.

3. Likewise, the exemption sought will not adversely affect safety because Kenneth J. Crawford will use trained technicians to perform maintenance,

alterati ons or preventive 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 Phantom 2 & 3 and DJI Inspire 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 Kenneth

J. Crawford ’s proposed operating limitations, the operating documents, and the technical aspects of

the DJI Phantom 2 & 3 and DJI Inspire UASs, Kenneth
J. Crawford submits that safety will not be adversely affected by granting exemption from 14 C.F.R.
Section s 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).

### 28 

### vii. 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, Kenneth J.
Crawford requests that the FAA prescribe special

conditions for the intended operation of the DJI Phantom

2 & 3 and DJI Inspire UASs, which contain such safety

standards that the Administ rator 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 sp ecial conditions will permit safe operation of the UAS for t he limited purpose of conducting aerial video and photography over certain areas of the United States for compensation or hire.

1. FMRA Section 333 sets forth the requirements for considering wheth er 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

Phantom 2 & 3 and DJI Inspire 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 r egulations 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 condition s 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 safet y equivalent to that established in the regulations. See 14 C.F.R. § 21.16.

### 29 

### 2. Therefore, in accordance with FMRA Section 333

and 14 C. F.R. §21.16, the FAA may prescribe special conditions for Leading Edge’s intended operation of

the DJI Phantom 2 & 3 and DJI Inspire UASs, which contain such safety standards that the 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).

6. A Summary That Can Be Published In The Federal Register, stating: T he
Rules From Which Kenneth J. Crawford Seeks Exemption: Kenneth J.

Crawford 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).

# Pre

- Flight

1. Weather: Carefully	check	the	latest	weather	and	wind	forecasts	for	the	area
that	will	be	surveyed	prior	to	submission	of	flight	request	and	NOTAM,	upon
ATC	pre

- flight	coor dination,	and	visually	immediately	prior	to	flight.	Be	aware and	mindful	of	the	effects	terrain	and	altitude	may	have	on	wind	direction, speed,	or	flight	operations. Windfinder prov ides	a	great	resource	for	wind	speed forecasts	of	many	locations	near	which	flight	operations	may	occur.



## 2. Hazards: Prior	to	flight,	the	PIC	will	make	every	effort	to	ensure	that	flight
operations	will	not	pose	any	undue	risk	to	the	personnel	directly	involv ed	with the	effort	and	to	members	of	the	public	who	are	not	directly	involved.	Likewise, make	every	effort	to	ensure	that	operations	will	not	pose	any	undue	risk	to	any property	in	the	area.



## a. Controlled	Airspace flights	shall	be	performed	only	with	permissi on	of

- RA

- and	in	constant	communication	with	all	required	parties	and agencies	and	the	controlling	authority	of	the	airspace.	The	controlling authority	maintains	the	right	to	abort	any	UAS/UAV	flights	regardless	of
the	stage	the	operation	is	in.	Comply	wi th	all	federal,	state,	and	local laws,	ordinances,	covenants,	and	restrictions	as	they	relate	to	UAS/UAV
operations.	Formally	request	permission	from	local	government	and local	communities	before	flying	over	their	airspace	whenever	possible	or required.	Li kewise,	request	permission	from	both	local	government	and local	communities	to	take	aerial	photographs/videos.	For	high

- quality, professional	mapping,	flying	at	300	meters	is	often	necessary.	If	these levels	exceed	the	legal	altitude	limits	in	the	country of	operation,	seek formal	permission	whenever	possible	and	notify	the	nearest	airport operator	of	the	intended	flight	plan


## b. Airspace: Ensure	that	all	operations	take	place	at	least three ( 3 )	miles
(or	the	minimum	distance	required	by	local	regulations)	from any controlled	airspace	such	as	an	airport	or	active	airfield.	Prior	to	taking off,	be	sure	to	scan	the	skies	for	any	signs	&	sounds	of	aircraft. When flying, apply	the	“see	and	avoid”	as	you continue	to	look	for	aircraft. If you	spot	or	hear	any, immed iately	land	your	UAS/UAV.		Referencing	the “Don’t	Fly	Drones	Here”	web	page	(link:

### 33 

### https://www.mapbox.com/drone/no

- fly/ )	provides	initial	location	checks for	areas	that	require	a	COA	or	prohibit	commer cial	drone	flight
operations.



## c. Launch	&	Landing	Sites: The	selection	of	launch	and	landing	sites	is
based	first	and	foremost	on	safety	and	thus	dependent	on	the	following:

i. Site	is	away	from	nonessential	participants,	utility	wires,	and poles;

ii. Ability	to	mai ntain	adequate	buffer	zones	between	aircraft	and personnel;

iii. Minimize	departures	and	landings	over	populated	areas;

iv. Take

- off	site	should	be	chosen	to	take	into	account	local topography,	ensuring	a	visible	line	of	sight	towards	the	UAV	at	all

times.

v. Typicall y	the	landing	site	is	the	same	as	the	launch	site.	However, an	alternative	landing	site	should	be	identified	if	the	primary landing	site	becomes	unusable	or	unsafe.	To	this	end launch/landing	sites	should	be	selected	based	on	the	availability

of	an	alterna tive	landing	site;

vi. The	availability	of	a	mission	“abort	site”	is	not	required	but

recommended.

vii. An	abort	site	is	one	where	the	UAV	may	be	“dumped”	in	the event	of	an	emergency	situation.

viii. If	landing	site	includes	other	flight	staff	announce	out	loud	“Clear

P rop”	before	starting	aircraft	power.


## d. Safety	Software: UAVs	increasingly	have	a	number	of	failsafe	options	in
case	of	failures	or	unexpected	situations.	These	often	include	using methods	of	stabilization	and	an	automated	Return/Home	option.	Other

features	i nclude	fail

- recovery	software	and	UAV	parachute. Make	sure

to	test	these	fail

- safe	mechanisms	before	you	start	flying.	Do	not	fly

without	these	failsafe	mechanisms.



## e. Mission Flight Plan: The	mission	plan	shall	contain	all	actions	and
contingencies	for	the mission	planned.	Any	limiting	factors	in	the	flight environment	may	alter	the	intended	operation	and	modify	the	mission plan	accordingly.	Contingency	planning	should	include	safe	routes	in	the event	of	a	system	failure,	degraded	performance,	or	lost	commu nication link,	if	such	a	failsafe	exists. Mission	plans	will	also	include	a	flight	plan when	flying	large	UAVs	and/or	when	flying	complex	missions.	Complex
missions	include	areas	that	have	several	ongoing	UAV	projects;	are	in

dense	urban	areas	and	or	clos e	to	airports.	Small	UAVs,	especially	when

flown	line

- of

- site,	do	not	require	formal	flight	plans.	Mission	plans	and flight	plans	should	be	shared	with	other	operators	when	flying	complex

missions.


## f. Public	Awareness: Pro

- actively	raise	public	awareness	abou t	intended

### 34 

### flight	plans/paths	so	as	to	avoid	scaring	local	communities	and
passersby.	Consider	using	flyers,	local	radio	and	newspapers	for disseminating	this	information,	particularly	when	flying	complex missions.	Meet	with	the	local	community	to	propose and	discuss	the flight	plan	whenever	possible.	In	addition,	explain	the	technology	and ask	for	their	authorization	before	flying.	Ideally,	give	something	back	to the	community	whenever	possible	(training,	printed	maps,	etc). Team

up a	local	operator	who	h as	experience	in	the	country,	speaks	the language	and	understands	the	culture.



## g. Camera	&	Settings: Ensure	that	the	camera	settings	are	appropriate	to
your	mission.	Make	sure	the	camera	batteries	are	fully	re

- charged	and that	there	is	sufficient	memory	on	th e	proper	speed	SD	card	to	record the	footage	for	your	mission.	Remember	to	start	the	video	or	photos before	launching	your	UAV	(you’d	be	surprised	how	easy	that	step	is	to overlook).


## h. Insurance: Make	every	effort	to	secure	individual	insurance	and	assume

al l	liability	for	your	actions.	UAS	NGOs	and	companies	who	collaborate with	our	network	are	also	required	to	secure	insurance.



## i. Obvious	but	for	the	Record: Do	not	operate	UAVs	while	under	the
influence	of	alcohol	or	while	using	any	drug	that	could	adversely	a ffect the	ability	to	safely	control	the	model.



## 3. Aircraft	Checks: Conduct a	thorough	inspection	of	the s UA S airframe	bef ore flight :



## a. Transmitter	firmware	up	to	date?



## b. Check	condition	of	props	(run	finger	along	leading	and	trailing	edges,	flex

# In

- Flight

1. Basics:

a. If	flying	manually,	a lways	keep	your	fingers	on	the	controller/transmitter.

b. Always	fly	the	sUAS	in	Line	Of	Sight	(LOS)	from	the	Ground	Control

Station.

### 36 

### c. Climb	to	a	safe	altitude	away	from	potential	hazards	and	to	reduce	noise pollution.	Keep	aircraft	at	a	safe	operating	distanc e	from	people,	electric utility	lines	and	buildings.	If	the	UAV	must	be	flown	over	buildings	or people,	use	a	lightweight	UAV	and	maintain	a	safe	altitude	for	recovery and	make	every	effort	to	minimize	exposure.



## 2. Spotter: Use	a	spotter	or	visual	observer	wh enever	possible	and	appropriate.



## 3. Laws:

a. The	PIC	will	maintain	a	see	and	avoid	manned	aircraft	operations	at	all times	prior	to	and	during	flight.

b. Do	not	fly	UAVs	within	five	miles	(or	whatever	is	defined	by	local	laws)	of any	private/commercial	airport/hel ipad	or	a	pre

- existing	UAV	flying	site without	a	frequency

- management	agreement.

c. Do	not	interfere	with	operations	and	traffic	patterns	at	any	airport, heliport	or	seaplane	base	except	where	there	is	a	written	mixed

- use
agreement.

d. Respect	altitude	limits	a s	stated	by	local/national	laws.



## 4. Landing:

a. Regardless	of	whether	of	a	manual	or	automated	UAV	landing,	scan landing	area	for	potential	obstruction	hazards.

b. Announce	out	loud	“Preparing	to	Land!”

c. Carefully	land	the	aircraft	away	from	obstructions	and	peopl e.



# Post

- Flight

1. 

## Shutting	Down:

a. Turn the power	off	to	the	aircraft	and/or	disconnect/remove	the battery(ies).

b. Turn	off	the	transmitter	and	range	extender	system.

c. Turn	the	power	off	to	the	photo	equipment.

d. Visually	check	aircraft	for	signs	of	damage	and/or excessive	wear.

e. Secure	the	aircraft.



## 2. Check	pictures: Verify	that	the	UAV	camera	actually	took	the	pictures.	If	not,	or
of	bad	quality,	consider	redoing	the	mission	with	a	spare	set	of	batteries.



## 3. Logs: Keep	a	detailed	logbook	of	all	flights.



## 4. Information	S haring: Request	permission	from	local	communities	to	share	the
resulting	imagery,	either	privately	or	publicly	for	humanitarian	purposes.	Freely share	imagery	with	local	communities	whenever	possible.	Consider	printing	the imagery	on	banners	as	these	are	m uch	more	durable	than	paper.



## 5. Aircraft	Checklist:

a. Weekly	or	every	ten	(10)	flights	(whichever	occurs	sooner):

i. Visual	inspection	of	shell	and	other	plastic	components	for cracking/damage	(landing	skids, camera	mounting	plates,	etc.);

### 37 

### ii. Check	tightness	of	motor retaining	screws	and	shell	ret aining screws	(both	2.0mm	hex);

iii. Clean	data	spring	pins	and	battery	contact	pads	with	alcohol	and swab	or	proprietary	electrical	contact	cleaner	and	cycle	spring pins	several	times	to	check	for	spring	weak ness	and	full unimped ed	travel;

iv. Plug	in	to	Vision	Assistant	and	check	tx	&	IMU	calibration	state and	all	battery	cells	have	good	bala nce	(repeat	for	all	batteries);

v. Check	batteries	for	number	of	cycles	and	discharge	per	DJI recommendations	if	required.

b. Monthly	or	every	forty	( 40)	flights (whichever	occurs	sooner):

i. Remove	upper	shell	and	check	state	of	all	wiring

- plugs	fully seated,	condition	of	all	solder	joints,	condition	of	visible	circuit boards	and	wiring	runs,	internals	generally	c lean	and	no debris/loose	items.

ii. Remove	m otors	and	check	security	of	E	clips,	condition	of	bearings and	general	visual	inspection.

iii. Remove	rubber cover	from	Vision	camera	servo

- mounting	point and	check	tightness	of	the	small	cross

- head	screw.

c. General Maintenance : To	ensure	that	your	aircraft	cont inues	to	offer optimal	performance	and	to	ensure	flight	safety,	it	is	recommended	that comprehensive	maintenance	be	performed	after	every	200	flights	or	50 flight	hours.	This	manual	is	intended	to	help	users	maintain	their	aircraft

and	maximize	its	continu ed	reliability.

i. Smart	Battery

1. Check	the	battery	for	damage	and	deformities.	If	there	are any	signs	of	damage	to	the	battery,	stop	using	it	and discharge	the	battery	to	10%	or	below	for	disposal.	Do	not disassemble	the	battery	for	any	reason.

2. Check	the	batt ery	pins	and	rub	them	clean	with	an	eraser	if any	residue	is	observed.	This	will	help	to	ensure	a	more

reliable	connection.

3. Check	the	metal	battery	power	connectors	for	damage.	If the	connectors	appear	burnt,	try	to	clear	them.	This	can	be done	by	insertin g	a	piece	of	sandpaper	(1mm	thick)	into the	connectors	to	polish	the	metal.

4. Check	the	contact	pins	in	the	battery	compartment	to ensure	that	the	pins	are	clear.	They	should	be	able	to establish	easy	contact	with	the	battery	connectors	and

should	not	be	ben t.

5. Check	the	electrodes	on	the	battery.	If	they	appear	burnt, polish	them	with	sandpaper.	If	there	is	serious	erosion, send	the	battery	in	for	repairs.

6. Check	the	plastic	components	of	the	battery	bracket	to	see

### 38 

### it	is	in	good	condition	and	that	all	screws	a re	secure.	This prevents	the	battery	from	becoming	loose	during	flight.

7. Check	the	power	cables	between	the	arms	and	the	center plate,	if	the	cables	are	worn,	contact	DJI	to	arrange	repairs.

8. For	long

- term	storage,	please	refer	to	the	“Intelligent Flight	Bat tery	Safety	Guidelines”	and	check	the	battery once	a	month	to	prevent	the	battery	cell	from	being damaged.

9. Run	the	DJI	Pilot	App	to	confirm	that	all	battery	cells	are	at similar	voltage	levels	and	stay	at	the	same	level	when	the battery	is	fully	charged.	I f	all	cells	maintain	voltage	levels above	3.7V	but	any	cell	is	0.2V	higher	or	lower	than	the others,	contact	DJI	for	analysis.	You	can	also	check	the battery	cell	warning	history.	If	any	warning	is	reported,

contact	DJI.

ii. Aircraft

1. Confirm	that	all	the	screw s	are	still	adequately	tightened.

2. Check	the	aircraft	for	breaks	or	damage.	If	there	is	any reason	to	believe	that	detectable	damage	might	affect flight	safety,	consult	with	DJI	Support.

3. Check	the	pads	on	the	bottom	of	landing	gears.	If	they	are loose,	repl ace	or	secure	them	with	502	glue.

4. Ensure	that	there	are	no	obstructions	on	or	around	the GPS	module	or	around	the	antennas	on	the	landing	gear. Remove	any	obstacles	(such	as	tapes,	decals	or	stickers with	conductive	material)	that	might	affect	or	block	the signal.

iii. Motors

1. Check	the	rotors	to	confirm	that	they	have	not	become

loose.

2. Detach	the	propellers	and	start	the	motors.	Listen carefully.	If	there	is	any	abnormal	noise,	please	replace	the motors.	This	may	be	a	sign	that	the	bearings	have	been

worn	out.

3. D etach	the	propellers	and	start	the	motors.	Carefully examine	the	edge	of	the	rotor	and	confirm	that	the	shaft	is perfectly	centered	on	the	motor.	Check	for	any	abnormal or	excessive	vibration.	If	any	problems	are	detected, contact	DJI	Support	to	order	repl acement	motors.

4. Check	for	deformities	by	confirming	that	the	gap	between

the	motor	and	motor	base	is	even.	If	not	contact	DJI Support	to	order	replacement	motors.

5. Ensure	that	the	screws	used	to	secure	the	motor	base	are
tight	and	the	plastic	components	aro und	the	motors	are	in

### 39 

### good	condition.	If	not	please	tighten	the	screws	and contact	DJI	to	repair	any	broken	plastic	components.

iv. Propellers

1. Check	the	propellers.	If	there	is	any	bending,	breakage	or cracking	on	a	propeller,	do	not	use	it.

2. Attach	the	propell er	to	the	motor,	turn	on	the	aircraft,	and place	it	on	the	ground.	Stand	1	meter	away	from	the aircraft	and	observe	the	rotating	propellers.	If	you	can	see two	distinct	propeller	outline	layers,	when	looking	at	a spinning	propeller	from	the	side,	this	prop eller	is	damaged

and	should	not	be	used.

v. IMU

1. Open	DJI	Pilot	app	to	check	the	condition	of	the	IMU	and perform	an	advanced	IMU	calibration.	Please	place	the
aircraft	in	a	cool	environment	and	on	a	flat,	stable	surface (if	the	landing	gear	is	damaged,	suppor t	the	aircraft	with four	objects	of	equal	height).	Do	not	touch	the	craft	during

the	calibration.

2. Turn	on	the	aircraft	and	listen	for	any	abnormal	noise	or

vibration	from	the	fan	located	on	the	front	of	the	aircraft. If	any	irregularity	is	detected,	replac e	the	fan.

vi. Control	and	Video	Transmission	System

1. Check	the	4	antennas	on	the	landing	gear	to	ensure	that they	are	secure.	Also	check	for	any	bending	or	damage.

2. Check	the	antennas	of	the	remote	controller	for	damage.

3. Check	the	neck	strap	for	damage	or	wear, replace	if

necessary.

vii. Gimbal	and	Camera

1. Confirm	that	the	gimbal	is	able	to	properly	stabilize	itself.	If its	stabilizing	performance	deteriorates,	contact	DJI	to
arrange	repairs.

2. Listen	for	any	abnormal	noise	from	the	fan	when	the gimbal	is	turned	on.	Thi s	may	indicate	unusual	vibration and	the	fan	should	be	replaced.

3. Check	rubber	vibration	dampers	for	positioning	and	tears.

4. Check	two	plastic	security	pins	for	positioning	and placement

viii. Vision	Positioning	System

ix. Check	the	lens	of	the	camera.	If	any	dirt	or residue	is	detected, gently	clean	the	lens.

x. Check	for	and	remove	objects	that	might	block	the	sensors.

xi. Ensure	that	the	Vision	Positioning	System	is	securely	installed	on

the	aircraft.
