Re: Exemption Request Section 333 of the FAA Reform Act 

Dear Sir or Madam: 

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

CFR Part 11, CAMBRIA HOBBY, LLC, hereby applies for an exemption from the listed Federal Aviation 

Regulations (“FARs”) to allow commercial operation of its Small Unmanned Aircraft Systems (“sUAS”) 

CAMBRIA HOBBY, LLC UAS Platform, a DJI Series Phantom 2, 3, Inspire 1 and Skyhunter foam air 

plane.

CAMBRIA HOBBY, LLC plans to engage in commercial UAV services to residential, commercial, 

industrial, and governmental clients in the following applications: 

• Aerial Videography & Photography, Mapping, and Aerial Assessments; 

• Agriculture Surveys and Assessments; 

• Real Estate Videography & Photography; 

• Damage Assessments Due to Natural Disasters; 

• Public Safety Mapping, Inspections, and Assessments with Search and Rescue; and, 

• Wind Farm Inspections.

• Power Line Inspections.

So long as such operations are conducted within and under the conditions outlined herein or as may be 

established by the FAA as required by Section 333. 

As detailed in this document, the requested exemption would permit the operation of sUAS under 

controlled conditions in airspace that is 1) limited 2) predetermined 3) controlled as to access, and 4) 

would provide safety enhancements to the already best practices and safety protocols followed by 

CAMBRIA HOBBY, LLC. Approval of this exemption would thereby enhance safety and fulfill the 

Secretary of Transportation’s (the FAA Administrator’s) responsibilities to “...establish requirements for 

the safe operation of such aircraft systems in the National Airspace System.” Section 333(c) of the 

Reform Act.

1. STATUTORY AUTHORITY FOR EXEMPTIONS

The Federal Aviation Act expressly grants the FAA authority to issue exemptions. This statutory 

authority includes exempting civil aircraft, as the term is defined under §40101 of the Act, including 

sUASs, from the requirement that all civil aircraft must have a current airworthiness certificate. 

The Administrator may grant an exemption from a requirement of a regulation prescribed under 

subsection (a) or (b) of this section or any sections 44702-44716 of this title if the Administrator finds 

the exemption in the public interest. 49 U.S.C. §44701(f) See also 49 USC §44711(a); 49 USC §44704; 

14 CFR §91.203(a) (1). 

Section 333(b) of the Reform Act assists the Secretary in determining whether sUAS may operate in 

the National Airspace System (NAS) without creating a hazard to the user, the public, or a threat to 

national security. In making this determination, the Secretary must consider: 

• The sUAS’s size, weight, speed, and operational capability; 

• Whether the sUAS operates within the visual line of sight of the operator 

• Whether the sUAS operates outside of highly populated areas and away from close proximity to 

airport 

Reform Act §333(a). If the Secretary determines that a sUAS “may operate safely in the national 

airspace system, the Secretary shall establish requirements for the safe operation of such aircraft in the 

national airspace system.” Id. §333(c). 

CAMBRIA HOBBY, LLC sUAS are multirotor vehicles and foam fixed wing RC air craft weighing 55 or 

fewer lbs. including payload. They operate under normal conditions at a speed of no more than 85 knots. 

The sUAS will only operate within the Pilot’s visual line of sight (VLOS) and will only operate within the 

predetermined flight plan boundaries. Such operations will insure that the sUAS will “not create a hazard 

to users of the national airspace system or the public.” Reform Act Section 333 (b).

Given the small size of the sUAS involved and the restricted and controlled environment within which 

they will operate, our application falls squarely within the zone of safety (an equivalent level of safety) 

in which Congress envisioned that the FAA must, by exemption, allow commercial operations of sUAS 

to commence immediately. Also due to the small size of the sUAS and the low altitudes and restricted 

areas in which the sUAS will operate, approval of the application presents no national security issue. 

Given the clear direction in Section 333 of the Reform Act, the authority contained in the Federal Aviation 

Act, as amended; the strong equivalent level of safety surrounding the proposed operations, and the 

significant public benefit, including enhanced safety, the grant of the requested exemptions is in the 

public interest. 

Accordingly, CAMBRIA HOBBY, LLC respectfully requests that the FAA grant the requested exemption 

in a timely manner. 

2. PUBLIC INTEREST

This exemption application is expressly submitted to fulfill Congress’ goal in passing Section 333(a) 

through (c) of the Reform Act. This law directs the Secretary of Transportation to consider whether 

certain unmanned aircraft systems may operate safely in the NAS before completion of the rulemaking 

required under Section 332 of the Reform Act. By granting an exemption the FAA will fulfill Congress’s 

intent of allowing UAS to operate with significant safety precautions in low risk environments. 

The use of sUAS on a Public and Private applications can significantly reduce the risk while inspecting, 

surveying, or monitoring missions. sUAS can inspect, photograph, and collect data on hard to get to 

areas that otherwise would require worker inspection. 

Additionally, sUAS could replace the use of helicopters and small aircraft to monitor sites. The sUAS 

we propose to fly in this application are under five pounds, and carry no combustible material on board, 

as opposed to the much larger conventionally powered small aircraft. Shifting to sUAS from helicopters 

presents a marked safety increase for our workers and the public. 

Lastly, sUAS reduce the environmental impact by dramatically decreasing the energy used for aerial 

imaging and data collection over a construction site. Our sUAS use rechargeable lithium ion batteries, 

as opposed to fossil fuels burned in operation of small aircraft that are many hundreds of times heavier. 

3. EQUIVALENT LEVEL OF SAFETY

CAMBRIA HOBBY, LLC proposes that the exemption requested herein apply to sUAS that have the 

characteristics and that operate with the limitations listed herein. These limitations provide for at least 

an equivalent or even higher level of safety to operations under the current regulatory structure 

because the proposed operations represent a safety enhancement to the already safe protocols 

followed on construction sites and imaging and surveying operations conducted with helicopters and 

other conventional aircraft.

CAMBRIA HOBBY, LLC will be bound by the following limitations when conducting its sUAS operations 

under an FAA issued exemption: 

1. The sUAS will be less than 55 pounds. 

2. Mission Planning will be conducted prior to each Mission 

3. Flights will be operated within visual line of sight (VLOS) of the Pilot, who will work with a 

Visual Observer (VO), as required. 

4. Maximum total flight time for each operational flight will be 20 minutes. The UAS calculates 

battery reserve in real time, and will return to its ground station with at least 20% battery 

power reserve, should that occur prior to the 15 minute limit. 

5. Flights will never exceed 400 feet, above the ground level (AGL). 

6. Crew for each operation will consist of a sUAS Pilot and VO who will keep the sUAS within 

their VLOS at all times. 

7. The sUAS Pilot will be a minimum holder of a Private Pilot Certificate with a Class 3 Medical 

or Issued State Driver’s License. 

8. The sUAS will only operate within a planned flight profile, unless conditions warrant a 

different path due to changing conditions or environment. 

9. All flights will be conducted within a set of weather constraining guidelines. 

10. If Flights are will in 5NM of a designed FAA Airports in Airport/Facility Directories (AFD), the 

PIC will contct the airport control tower. 

11. A briefing will be conducted in regard to the planned sUAS operations prior to each day’s 

flights. It will be mandatory that all personnel who will be performing duties within the 

boundaries of the safety perimeter be present for this briefing. 

12. All flights will have prior consent from property owners or representatives. 

13. Pilots will have been trained in operation of UASs generally and received up-to-date 

information on the particular UAS. 

14. All required permissions and permits will be obtained from territorial, state, county, or city 

jurisdictions, including local law enforcement, fire, or other appropriate agencies. 

15. If the sUAS loses communications or loses its GPS signal, it will have capability to enter 

“loiter mode” and hover, reestablish satellite connection, and return to a pre- determined 

location within the flight plan’s controlled airspace. 

4. DESCRIPTION OF SPECIFIC REGULATIONS

14 CFR 61.113 (a) & (b): Private pilot privileges and limitations: Pilot in command

Sections 61.113 (a) & (b) limit private pilots to non-commercial operations. Because the sUAS will not 

carry a pilot or passengers, the proposed operations can achieve the equivalent level of safety of current 

operations by requiring the Pilot operating the aircraft to have completed a sUAS minimum of 100 Cycles 

of Landing and Takeoff with a minimum of 20 Flight Hours in an aircraft craft. Unlike a conventional 

aircraft that carries the pilot and passengers, the sUAS is remotely controlled with no living thing or 

cargo on board. DJI UAS Platforms are also operated by an autopilot, which greatly reduces the danger 

of human error. The area of operation is controlled and restricted, and all flights are planned and 

coordinated in advance as set forth in a predetermined route and flight plan.

The sUAS to be operated hereunder is less than 10 pounds fully loaded, carries neither a pilot nor 

passenger, carries no explosive materials or flammable liquid fuels, and operates exclusively within a 

secured area as set out in the flight plan. Like other civil aircraft, operations under this exemption will 

be tightly controlled and monitored by the operator, pursuant to the flight plan’s requirements, and under 

the requirements and in compliance with local public safety requirements, to provide security for the 

area of operation as is currently done on active construction sites. The FAA will have advance notice of 

all operations. 

The risks associated with the operation of the sUAS are therefore diminished from the level of risk 

associated with commercial operations contemplated by Part 61 when drafted, and allowing operations 

of the sUAS as requested with a Pilot who has met the minimum requirements established by 14 CFR 

§61.113 (a) & (b). 

14 CFR 91.103: Preflight Action

This regulation requires each pilot in command take certain actions before flight to ensure the safety of 

flight. An exemption is needed from this requirement as the Pilot will take separate preflight actions, 

including checking for weather conditions, checking flight battery requirements, checking takeoff and 

landing distances, and all other actions in the Pre-flight Checklist. These actions will provide an 

equivalent level of safety. 

14 CFR 91.119: Minimum Safe Altitudes

Section 91.119 establishes safe altitudes for operation of civil aircraft. Section 91.119 (d) allows 

helicopters to be operated at less than the minimums prescribed, provided that the person operating 

the helicopter complies with any route or altitudes prescribed for helicopters by the FAA. This exemption 

is for a multirotor craft that flies similarly to a helicopter, with vertical takeoff and vertical landing, which 

will typically operate at altitudes of 200 AGL, so an exemption may be needed to allow such operations. 

The sUAS will never operate at altitude higher than 400 AGL and will have a mission flight profile, where 

buildings and people will not be exposed to operations, without their pre-obtained consent. 

The equivalent level of safety will be achieved given the size, weight, speed of the sUAS, as well as the 

location where it is operated. No flight will be taken without the permission of the property owner or local 

officials. 

Because of the advance notice to the property owner and any onsite personnel as outlined in the flight 

plan, all affected individuals will be aware of the planned flight operations. Unlike flight operations with 

aircraft or rotorcraft weighing far more than the maximum 10 lbs. proposed herein, our sUAS will not 

carry flammable fuel. In addition, the low-altitude operations of the sUAS will ensure separation between 

sUAS operations and the operations of conventional aircraft that must comply with Section 91.119. 

14 CFR 91.121: Altimeter Settings

This regulation requires each person operating an aircraft to maintain cruising altitude by reference to 

an altimeter that is set “...to the elevation of the departure airport or an appropriate altimeter setting 

available before departure.” As the sUAS may not have a barometric altimeter, but instead a GPS 

altitude read out, an exemption may be needed. An equivalent level of safety will be achieved by the

operator, pursuant to the Pre-flight and Safety Check list, confirming the altitude of the launch site shown 

on the GPS altitude indicator before flight. 

14 CFR 91.151 (a): Fuel requirements for flight in VFR conditions 

Section 91.151 (a) outlines fuel requirements for beginning a flight in Visual Flight Rules (VFR) 

conditions. Our sUAS is limited to operations in sterile and controlled environments and has a limited 

range and flight time which require an exemption from 14 CFR 91.151(a). 

The battery powering the sUAS provides approximately 20 minutes of powered flight. To meet the 30 

minute reserve requirement in 14 CFR §91.151, sUAS flights would be limited to approximately 10 

minutes in length. Given the limitations on the sUAS’s proposed flight area and the location of its 

proposed operations within a predetermined area, a longer time frame for flight in daylight or night VFR 

conditions is reasonable. 

CAMBRIA HOBBY, LLC believes that an exemption from 14 CFR §91.151(a) falls within the scope of 

prior exemptions. See Exemption 10673 (allowing Lockheed Martin Corporation to operate without 

compliance with FAR 91.151 (a)). Operating the small sUAS, in a tightly controlled area where only 

people and property owners or official representatives who have signed waivers will be allowed, with 

less than 30 minutes of reserve fuel, does not engender the type of risks that Section 91.151(a) was 

intended to alleviate given the size and speed of the small UAS. Additionally, limiting sUAS flights to 10 

minutes would greatly reduce the utility for which the exemption will be granted. 

An equivalent level of safety can be achieved by limiting flights to 30 minutes, or enough battery reserve 

to ensure that the sUAS lands at the ground station with at least 20% of battery power (as determined 

by the onboard monitoring system and the Pilot), whichever happens first. This restriction would be 

more than adequate to return the sUAS to its planned landing zone from anywhere in its limited 

operating area. 

Similar exemptions have been granted to other operations, including Exemptions 2689F, 5745, 10673, 

and 10808. 

14 CFR 91.405 (a); 407 (a)(1); 409 (a)(2); 417 (a) & (b): Maintenance inspections

These regulations require that an aircraft operator or owner “shall have that aircraft inspected as 

prescribed in subpart E of this part and shall between required inspections, except as provided in 

paragraph (c) of this section, have discrepancies repaired as prescribed in part 43 of this chapter...,” 

and others shall inspect or maintain the aircraft in compliance with Part 43. 

Given that these sections and Part 43 apply only to aircraft with an airworthiness certificate, these 

sections will not apply to CAMBRIA HOBBY, LLC. Maintenance will be accomplished by the operator 

pursuant to the sUAS’s operations manual. An equivalent level of safety will be achieved because these 

small sUAS are very limited in size and will carry a small payload and operate only in restricted areas 

for limited periods of time. If mechanical issues arise the sUAS can land immediately and will be 

operating from no higher than 400 feet AGL. The Pilot will ensure that the sUAS is in working order prior 

to initiating flight, perform required maintenance, and keep a log of any maintenance performed. 

Moreover, the Pilot is the person most familiar with the aircraft and best suited to maintain the aircraft 

in an airworthy condition to provide the equivalent level of safety.

Pursuant to 14 CFR Part 11, the following summary is provided for publication in the Federal Register, 

should it be determined that publication is needed: 

Applicant seeks an exemption from the following rules: 14 CFR §21, subpart H; 14 C.F.R 45.23(b);14 

CFR §§ 61.113( a) & (b);91.7(a); 91.9 (b) (2);91.103(b);91.109; 91.119; 91.121; 91.151(a);91.203(a) 

and (b); 91.405 (a); 91.407 (a) (1); 91.409 (a) (2); 91.409 (a) (2) and 91.417 (a) & (b) to operate 

commercially a small unmanned vehicle (55lbs or less) in construction operations. 

Approval of exemptions allowing commercial operations of sUAS in the public/private sector enhances 

safety while reducing risk. Manned aircraft monitoring and surveying creates a greater risk because the 

craft are much larger, have combustible fuel, and carry an onboard human pilot. In contrast, a sUAS 

weighing fewer than 10 lbs. and powered by batteries eliminates virtually all of that risk given the 

reduced mass and lack of combustible fuel carried on board. The sUAS will carry no passengers or 

crew and, therefore, will not expose them to the risks associated with manned aircraft flights. 

The operation of small sUAS, weighing less than 55 lbs., conducted in the strict conditions outlined 

above, will provide an equivalent level of safety supporting the grant of the exemptions requested herein, 

including exempting the applicant from the requirements of Part 21 and allowing commercial operations. 

These lightweight aircraft operate at slow speeds, close to the ground, and in a sterile environment and, 

as a result, are far safer than conventional operations conducted with turbine helicopters operating in 

close proximity to the ground, structures, and people. 

Privacy

All flights will occur over private or controlled access property with the property owner’s prior consent 

and knowledge. Images taken will be of individuals who have also consented to being filmed or 

otherwise have agreed to be in the area where aerial photography will take place. 

Satisfaction of the criteria provided in Section 333 of the Reform Act of 2012--size, weight, speed, 

operating capabilities, proximity to airports and populated areas and operation within visual line of sight 

and national security – provide more than adequate justification for the grant of the requested 

exemptions allowing commercial operation of applicant’s sUAS in public/private sector as defined above 

Sincerely, 

Mark Mondello
