Exemption No. 12320

Regulatory Docket No. FAA–2015-1467

Mr. Ronnie Krupa

T. Layne Enterprises LLC dba 4 Forks Media Production

3062 Hogback Hill

P.O. Box 3

Mineral Springs, PA 16855

Dear Mr. Krupa:

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 April 28, 2015, you petitioned the Federal Aviation Administration (FAA) on 

behalf of T. Layne Enterprises LLC dba 4 Forks Media Production (hereinafter petitioner or 

operator) for an exemption. The petitioner requested to operate an unmanned aircraft system 

(UAS) to conduct aerial data collection.

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 the 3D Robotics IRIS+ Professional.
2

The petitioner requested relief from 14 CFR part 21, Certification procedures for products 

and parts, Subpart H—Airworthiness Certificates. 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 the requested 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, T. Layne Enterprises, LLC dba 4 Forks Media 

Production 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 

 

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.

grounds for the immediate suspension or rescission of this exemption.

1. Operations authorized by this grant of exemption are limited to the 3D Robotics IRIS 

+ Professional 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.

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. 

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 
5

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 

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 
6

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 

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

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.

Professional UAS that will be operated by T. Layne Enterprises, LLC 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, T. Layne Enterprises, LLC, 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 3D Robotics IRIS+ Professional 

UAS in the National Airspace System (NAS), and for an exemption from the 

requirements of 14 C.F.R§§ 61.113(a) & (b), 91.109, 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, T. Layne Enterprises, LLC’s operation of 

3D Robotics IRIS+ UAS 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, T. Layne Enterprises, LLC 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.

T. Layne Enterprises, LLC submits that the requested relief is proper since an equivalent

level of safety will be ensured. T. Layne Enterprises, LLC 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 3D Robotics IRIS+ Instruction Manual). 

Furthermore, T. Layne Enterprises, LLC will document and maintain all maintenance

records for the 3D Robotics IRIS+ Professional UAS. T. Layne Enterprises, LLC seeks 

relief from Section 91.7(a), entitled Civil aircraft airworthiness, because the 3D Robotics 

IRIS+ Professional UAS do not require an airworthiness certificate in accordance with 14 

C.F.R. Part 21, Subpart H. As such, T. Layne Enterprises, LLC submits that it will ensure 

that the 3D Robotics IRIS+ Professional UAS is 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 3D Robotics Instruction Manual), and that the 

aircraft are in a condition for safe flight. T. Layne Enterprises, LLC also seeks an 

exemption from the requirements of Section 91.121, entitled Altimeter Settings, as the 

3D Robotics IRIS+ Professional UAS will not have a typical barometric altimeter 

onboard. However, altitude information of the 3D Robotics IRIS+ Professional UA 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 T. Layne 

Enterprises, LLC’s operation of the 3D Robotics IRIS+ Professional UAS within visual 

line of sight, at or below 200 feet AGL, will ensure a level of safety equivalent to Section 

91.121.

Additionally, T. Layne Enterprises, LLC seeks an exemption from the requirements of

Section 91.151(b), entitled Fuel requirements for flight in VFR conditions. T. Layne 
T. Layne Enterprises, LLC Petition for Exemption Section 333 FAA 6

Enterprises, LLC submits that safety will not be affected by operation of the 3D Robotics 

IRIS+ Professional UA during daylight hours in visual meteorological conditions (VMC) 

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

approximately 15 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, 

T. Layne Enterprises, LLC provides the following information in support of its petition 

for exemption:

C. The Extent Of Relief T. Layne Enterprises, LLC Seeks And The Reason T. Layne 

Enterprises, LLC The Relief.

2. Extent Of Relief T. Layne Enterprises, LLC Seeks And The Reason T. Layne 

Enterprises, LLC 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 T. Layne Enterprises, LLC to determine that the 3D Robotics IRIS+

UAS are in airworthy condition prior to every flight by ensuring that the UAS is in 

compliance with the operating documents (i.e., the Monthly Maintenance Log, and 3D 

Robotics IRIS+ Professional Instruction Manual).

T. Layne Enterprises, LLC seeks the requested relief because the 3D Robotics IRIS+

UAS do not require an airworthiness certificate in accordance with 14

C.F.R. Part 21, Subpart H. Therefore, T. Layne Enterprises, LLC will ensure that the

3D Robotics IRIS+ UAS is in airworthy condition based upon its compliance with the 

operating documents (i.e., Monthly Maintenance Log, and 3D Robotics IRIS+ 

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 limitations below.
T. Layne Enterprises, LLC Petition for Exemption Section 333 FAA 9

3. Extent Of Relief T. Layne Enterprises, LLC Seeks And The Reason T. Layne 

Enterprises, LLC Seeks Relief From Section 91.121.

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

operations of the 3D Robotics IRIS+ Professional UAS, 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 

(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), T. Layne 

Enterprises, LLC seeks the requested relief because the 3D Robotics IRIS+ 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 3D Robotics IRIS+ 

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 T. Layne Enterprises, LLC Seeks And The Reason T. Layne 

Enterprises, LLC 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 3D Robotics 

IRIS+ Professional UAS 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 4.5 minutes. T. Layne Enterprises, LLC seeks the requested relief because without 

an exemption from Section 91.151(b), the flight time duration of the battery powered 3D 

Robotics IRIS+ UA will severely constrain the practicality of any

aerial video or still photo flight operations that T. Layne Enterprises, LLC proposes to

conduct pursuant to this Petition. Significantly, as set forth below, the technical 

specifications of the 3D Robotics IRIS+ Professional operating documents, and T. Layne 

Enterprises, LLC proposed operating limitations, ensure that

T. Layne Enterprises, LLC will safely operate the battery powered 3D Robotics IRIS+

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 T. Layne Enterprises, LLC Seeks And The Reason T. Layne Enterprises, 

LLC Seeks Relief From Section 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, T. Layne Enterprises, LLC 

requests relief from these Sections because the 3D Robotics IRIS+ Professional UAS do 

not require airworthiness certificates. As set forth more fully below, the 3D Robotics 
T. Layne Enterprises, LLC Petition for Exemption Section 333 FAA 10

IRIS+ Professional UAS meet the conditions of FMRA Section 333 for operation without 

an airworthiness certificate. Accordingly, T. Layne Enterprises, LLC will use trained 

technicians to perform maintenance, alterations, or preventive maintenance on the UAS 

using the methods, techniques, and practices prescribed in the UAS operating

documents (i.e., the Monthly Maintenance Log, and 3D Robotics IRIS+ Professional

Instruction Manual). Furthermore, T. Layne Enterprises, LLC will document and

maintain all maintenance records for the 3D Robotics IRIS+ UAS.

D. The Reasons Why Granting T. Layne Enterprises, LLC Request Would Be In The

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

Granting the present Petition will further the public interest by allowing T. Layne

Enterprises, LLC to safely, efficiently, and economically perform aerial video and 

photography of real estate, special events, film sets, and landscape over certain areas of 

the United States.

Additionally, use of the 3D Robotics IRIS+ Professional UAS will decrease congestion 

of the NAS, reduce pollution, and provide significant benefits to the economy. Notably, 

the benefits of T. Layne Enterprises, LLC ‘s proposed operation of the 3D Robotics 

IRIS+ UAS will be realized without implicating any privacy issues.

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

The 3D Robotics IRIS+ Professional UA 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 3D Robotics IRIS+ 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 3D Robotics IRIS+

Professional UA 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 3D Robotics IRIS+

UAS.

Conducting aerial acquisitions with the 3D Robotics IRIS+ Professional UAS, 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 3D Robotics IRIS+

Professional UAS 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 3D Robotics IRIS+ Professional UA, 

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 3D Robotics IRIS+ Professional UAS to perform aerial 
T. Layne Enterprises, LLC Petition for Exemption Section 333 FAA 11

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 3D Robotics IRIS+ UAS (weighing approximately 2 pounds 8

ounces, at their maximum gross weights with lengths of 19 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).

3. Performing Aerial Video and Photography Operations With The 3D Robotics IRIS+

UAS Will Benefit The Economy.

In addition to being safe and efficient, the 3D Robotics IRIS+ Professional is also an 

economical alternative to using manned aircraft to conduct similar aerial operations. As 

such, operation of the 3D Robotics IRIS+ Professional UAS will allow United States 

based companies, like T. Layne Enterprises, LLC, 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 3D Robotics 

IRIS+ Professional UAS 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 3D Robotics 

IRIS+ Professional UAS, companies such as T. Layne Enterprises, LLC, 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 3D Robotics 

IRIS+ Professional UAS, 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, T. Layne Enterprises, LLC proposed operation of the 3D Robotics IRIS+ UAS 

would not implicate any privacy issues. Specifically, the 3D Robotics IRIS+ UAS will be

operated only in compliance with operating documents (i.e., the Monthly Maintenance 

Log, 3D Robotics IRIS+ 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
T. Layne Enterprises, LLC Petition for Exemption Section 333 FAA 12

Provided By The Rule From Which T. Layne Enterprises, LLC Seeks Exemption.

1. Reasons Why The 3D Robotics IRIS+ 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, T. Layne Enterprises, LLC’s operation of the 3D Robotics IRIS+ UAS 

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 rule-making 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

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, T. Layne Enterprises, LLC submits that the 3D Robotics 

IRIS+ UAS can operate safely in the NAS pursuant to FMRA Section 333, as

demonstrated by: (a) the characteristics of the 3D Robotics IRIS+ Professional UAS;

and (b) the specific operating limitations.

a. The Specifications Of The 3D Robotics IRIS+ Professional UAS Demonstrate Its Safe 

Characteristics.

The 3D Robotics IRIS+ Professional UAS does 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.

the Control Link is lost, the 3D Robotics IRIS+ UA will remains stationary, in flight. If, 

the 3D Robotics IRIS+ Professional UA does not reacquire control link data from the 

GCS, the UA will assume that the Control Link is lost and the UA 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 3D Robotics IRIS+

UAS are set forth at page 7 of the 3D Robotics IRIS+ Professional User Manual, attached 

hereto as B.

iv. The 3D Robotics IRIS+ Professional GCS And Its Operation.

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

Would Not Adversely Affect Safety.

T. Layne Enterprises, LLC 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 3D Robotics IRIS+ unless they have read and agreed to adhere to the 3D Robotics 

IRIS+ Instruction manual and have had adequate supervised flying time under the 

supervision of an experienced operator, 

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).

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, T. Layne Enterprises, LLC will ensure that the 3D Robotics 

IRIS+ 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.
T. Layne Enterprises, LLC Petition for Exemption Section 333 FAA 17

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

the altitude information of the 3D Robotics IRIS+ UA 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 T. Layne Enterprises, LLC operation of the 3D Robotics 

IRIS+ UAS 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 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).

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 3D 

Robotics IRIS+ UAS; (2) the limitations on the proposed flight operations; and

(3) the location of the proposed flight operations. Accordingly, T. Layne Enterprises, 

LLC will ensure that it will safely operate the battery powered 3D Robotics IRIS+

Professional UA 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 3D Robotics IRIS+ 

UAS; 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 3D Robotics IRIS+ Professional 

UAS 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 3D Robotics IRIS+ UAS 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 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, T. Layne Enterprises, LLC submits that the equivalent level of

safety with regard to the regulatory maintenance and alteration requirements established 
T. Layne Enterprises, LLC Petition for Exemption Section 333 FAA 18

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

met because T. Layne Enterprises, LLC will use trained technicians to perform 

maintenance, alterations, or preventive maintenance on the UAS using the methods, 

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

Maintenance Log, and 3D Robotics IRIS+ Professional Instruction Manual). 

Furthermore, T. Layne Enterprises, LLC will document and maintain all maintenance 

records for the 3D Robotics IRIS+ Professional UAS. Since the 3D Robotics IRIS+ 

Professional UAS will be inspected as prescribed by the operating documents, T. Layne 

Enterprises, LLC 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 3D Robotics IRIS+ User 

Manual is attached hereto as Exhibit B; a copy of the 3D Robotics IRIS+UAS 

Maintenance LOG is attached hereto as Exhibit C. Likewise, the exemption sought will 

not adversely affect safety because T. Layne Enterprises, LLC will use trained 

technicians to perform maintenance, alterations 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

3D Robotics IRIS+ Professional UAS 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 T. Layne Enterprises, LLC proposed operating 

limitations, the operating documents, and the technical aspects of the 3D Robotics IRIS+ 

Professional UAS, T. Layne Enterprises, LLC 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, T. Layne Enterprises, LLC
