Re: Exemption Request Under Section 333 of the FAA Reform Act and Part 11 of the Federal
Aviation Regula tions

Dear Madam, Sir,

Pursuant to Section 333 of the FAA Modernization and Reform Act of 2012 (the “Reform Act”)
and 14 C.F.R. Part 11, Ensign Engineering and Land Surveying, Inc

. (“ Ensig n ”)

, an operator of the eBee Unmanned Aircraft System (“eBee”) see ks an exemption from the Federal Aviation Regulations (“FARs”) listed below:

 14 C.F.R. 21

 14 C.F.R. 61.133(a) (b)

 14 C.F.R. 91.7(b)

 14 C.F.R. 91.119

 14 C.F.R. 91.151(a)

 14 CFR Subpart E (91.401

- 91.417)

The requested exemption would authorize comme rcial operat ions using the eBee for aerial mappin g and survey applications. These operations will be subject to strict operating requirements defined in the eBee user manual ( Ensign requests the FAA treat the eBee training program as proprietary under 14 C .F.R. 11.35(b) and does not include this document in the public docket and

conditions defined in the paragraph 3

.

Ensign was founded in 1987 and is a full service engineering firm specializing in civil engineering, structural engineering, and land surveyi ng. Ensign is committed to quality service and excellence and is always seeking ways to improve the services and products provided to customers and the community.

1. CHARACTERISTICS OF THE AIRCRAFT

The eBee is a small (37.8 inches wingspan) and ultra

- l ight (maximum take

- off weight of 1.7 pounds) platform made of flexible foam that performs pre

- programmed precision aerial mapping

missions thanks to the on

- board GPS and the related flight management software (eMotion) that allows the operator to plan safe ly and efficiently a mission in 3D, and then monitor it in real

- time. Thanks to the embedded camera, protected by a foam envelope, the eBee takes a collection of high

- definition still images that are used later to generate maps and contour lines of the sur veyed

area.

The four main characteristics of the eBee are:a. Very light weight

The eBee is so light that the operator can launch it by hand and let it land on almost any surface without requiring a parachute or landing net (belly land). Its low impact energy ( 38 J in case of a controlled emergency landing ) also significantly reduces the risk of hazardous situations. Finally, the wings of the eBee are detachable and made of flexible foam with no sharp or hard edges and almost no internal strengthening s tructure.

b. Electric

- powered

The eBee is electric powered. A brushless engine technology makes it silent and reliable. The propeller is attached with a rubber band to the body of the plane so that it can easily flex away in case of contact with any obje ct.

c. Semi

- automatic flight

The artificial intelligence incorporated within the eBee autopilot system continuously analyzes

data from the Inertial Measurement Unit and from the onboard GPS and takes care of all the aspects of the flight under the super vision of the operator.

d. Option for Manual control

Additionally, the eBee provides an override capability that allows the operator to take manual actions during the flight (Go to Home, Go Land, Hold and Resume the mission) and also suspend automated op erations and take manual control of the aircraft should it become necessary to respond emergent circumstances, thanks to the remote controller provided with the system.

2. APPLICATIONS

Using the eBee’s sensor technology, Ensign will be able to collect time

- specific imagery and

elevation information. Once the entire terrain of interest is flo wn, images collected during the flight will be merged together in a software program to make a topographic model. Using specific mathematical equations within the Postflight Terra 3D software, project field conditions, terrain characteristics and potential hazard areas can be easily identified.

The eBee will be used to evaluate information, including but not limited to:

 Topographic characteristics

 Volumetric estimates

 Slope and terrain impediments

 Natural and cultural resource identification

 As

- built fea ture identification and analysis

 Hazard evaluation

 Project design evaluations

Usually, in order for Ensign to meet the requests of clients , a flyover by a large aircraft is

required, at great cost to the client. T h is can negatively impact their efficient use of time, money

and resources.Ensign strives to eliminate the gu esswork out of project planning and design. By using real

- time,

aerial imagery to study time

- specific field conditions and three dimensional terrain data, Ensign

can better provide clients with timely and highly

- accurate data at a fraction of the cost for

traditional aerial survey and significantly increase the level of safety when acquiring such data

.

3. APPLICABLE LEGA L STANDARD UNDER SECTION 333

a. Airworthiness assessment of the eBee

Ensign notes that the airworthiness of the eBee has already been demonstrated for different projects in the United States, involving state/federal agencies or universities (among others the New Mexico State University: https://newscenter.nmsu.edu/Articles/view/10208/nmsu

- uas

- ebee

- ai rworthiness

- assessment , and the USACE New Orleans, who coordinated with the Department of Army and the FAA to obtain all authorizations required i n order to operate the eBee UAS). Moreover the eBee already received 15 Exemptions from the

FAA

.

SenseFly al so obtained flight approvals for the eBee (delivered by national civil aviation authorities) in many countries, among others:

 Switzerland (flight approval for VLOS operations)

 Canada (flight approval for VLOS operations)

 Australia (flight approval for VLO S operations)

 France (flight approval for Extended

- VLOS operations)

 Germany (flight approval for VLOS operations)

 United Kingdom (flight approval for VLOS operations)

 Norway (flight approval for VLOS operations)

 Sweden (flight approval for VLOS operations)

 Denmark (flight approval for VLOS operations)

b. Operating requirements

Grant of the exemption to Ensign for the eBee will be subject to the following operating

conditions :

 1. Operations authorized by this grant of exemption are limited to the SenseFl y eBee 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 o perated 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 mu st 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.

driv er’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 durati on of the flight. The PIC must ensure that the VO can perform the duties required of the VO.

 7. This exemption and all documents needed to operate the UAS and conduct its operations in accordance with the conditions and limitations stated in this grant of exemption, are hereinafter referred to as the operating documents. The operating documents must be accessible during UAS operations and made available to the Administrator upon request. If a discrepancy exists between the conditions and limitations

in thi s 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 upda te 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 revise d 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 flig ht 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

leas t 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 conditio n 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. T he 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

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 Colombia, Puerto Rico, a territory, a possession, or the Federal government. The PIC must also meet the flight review requirements specified in 14 CFR § 61.56 in an aircraft in which the PIC is rated on his or her pilot certificate

.

 14. The operator may not permit any PIC to operate unless the PIC demonstrates the ability to safely operate the UAS in a manner consistent with how the UAS will be 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, pro ficiency, 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 o nly 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

fr om 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 rul es (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 a s 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.

SHOWINGS UNDER APPLICABLE RULES SUBJECT TO EXEMPTION

ENSIGN requests an exemption from the following regulations as well as any additional regulatio ns that may technically apply to the operation of the eBee:

14 C.F.R. Part 21, Subpart H: Airworthiness Certificates
14 CFR § 91.203(a)(1)

Section 91.203 requires all civil aircraft to have a certificate of airworthiness. Part 21, Subpart H,

entitled A irworthiness Certificates, establishes the procedural requirements for the issuance of airworthiness certificates as required by FAR § 91.203(a). Given the size of the eBee, its very light weight (the maximum take

- off weight is 1.7 pounds) and the limited operating area associated with its utilization, it is unnecessary to go through the certificate of airworthiness process under Part 21 Subpart H in order to achieve or exceed current safety levels.

Such an exemption meets the requirements of an equivalen t level of safety under Part 11 and

Section 333 of the Reform Act. The Federal Aviation Act and Section 333 of the Reform Act both authorize the FAA to exempt aircraft from the requirement for an airworthiness certificate, upon
consideration of the size, w eight, speed, operational capability, and proximity to airports and populated areas of the UAS involved. An analysis of these different criteria demonstrates that the eBee operated without an airworthiness certificate, under the conditions proposed in that exemption, will be at least as safe, or safer, than a conventional aircraft with an airworthiness certificate. A proprietary risk assessment for operations with the eBee, which demonstrates that assertion, is also being submitted to the FAA as part of thi s application. ENSIGN requests the FAA treat the eBee risk assessment as proprietary under 14 C.F.R. 11.35(b) and not include this document in the public docket.

14 C.F.R. § 61.3: Requirements for certificates, ratings and authorizations

14 C.F.R. § 61.11 3(a) & (b); 61.133(a): Private Pilot Privileges and Limitations; Pilot in
Command; Commercial Pilot Privileges and Limitations

The regulation provides that no person may serve as a required pilot flight crewmember of a civil

aircraft of the United States , unless that person:

(1) Has a pilot certificate or special purpose pilot authorization issued under this part in that person's physical possession or readily accessible in the aircraft when exercising the privileges of that pilot certificate or authoriz ation. However, when the aircraft is operated within a foreign country, a pilot license issued by that country may be used.

The regulation provides also that no person that holds a private pilot certificate may act as pilot in

command of an aircraft for c ompensation or hire. Subparagraph (b) allows a private pilot to act as pilot in command of an aircraft in connection with any business or employment if:

(1) The flight is only incidental to that business or employment; (2) The aircraft does not carry p assengers or property for compensation or hire.

Given the safety features of the eBee and the fact that the missions are pre

- programmed and

monitored in real

- time with a specific flight management software (eMotion), SenseFly proposes that operators of th e eBee should not be required to hold a commercial pilot certification. Instead, operators should be required to:Have a sport or recreational pilot license (at least) and have successfully passed a manufacturer’ s

training program for the eBee.

14 C.F.R. § 91.7(a): Civil aircraft airworthiness

This regulation requires that no person may operate a civil aircraft unless it is in airworthy

condition. Should the exemption be granted allowing commercial operation of the eBee without

an airworthiness certifi cate, no standard will exist for airworthiness of the eBee. Given the size of the aircraft and the previous airworthiness assessments given to the eBee, among others:

 New Mexico State University: https://newscenter.nmsu.edu/Articles/view/10208/nmsu

uas

- flight

- test

- center

- conducts

- ebee

- airworthiness

- assessment

 USACE New Orleans, who coordinated with the Department of Army and t he FAA to obtain all authorizations required in order to operate the eBee UAS for levee system monitoring, documentation of construction progress, and extensive oblique photography

of USACE structures & activities

An equivalent level of safety will be ach ieved by insuring compliance with the SenseFly manuals prior to each flight.

14 CFR § 91.119: Minimum Safe Altitudes

The regulation provides that over sparsely populated areas the aircraft cannot be operated closer than 500 feet to any person, vessel, vehicle, or structure. Since the aircraft will be operating at a maximum of 400 feet AGL, the eBee cannot comply with this requirement.

The equivalent level of safety will be achieved because the eBee will only fly over private property with the permissio n of the landowner. The operator will define before every flight a working area radius and a flight area ceiling, preventing the eBee to go beyond the flight area. The landowner and the persons who may be on the ground in the flight area will be briefed of the expected route of flight and the associated risks to persons and property on the ground. Due to the small size of the eBee and the material with which the eBee is built, the hazard to persons, vessels, vehicles, and structures is not comparable to man ned aircraft and should be considered in granting the exemption.

Moreover, the aircraft will not be operated over congested areas nor over any open

- air assembly of persons. The aircraft will be operated at an altitude allowing, if a power unit fails, an emergency landing without undue hazard to persons or property on the surface.

14 C.F.R. § 91.151(a): Fuel Requirements for Flight in VFR Conditions

The regulation provides that no person may begin a flight in an airplane under day

- VFR

conditions unless t here is enough fuel to fly to the first point of intended landing and to fly after

that for at least 30 minutes.

Given the area of operation for the eBee

, ENSIGN believes that an equivalent level of safety is already achieved with the specific procedure p reventing the eBee to accept a take

- off order is the battery level is below a given value. Moreover, SenseFly has integrated “low” and “critical” battery level warnings and implemented a “return to Home” (and “Go Land”) actions in these

situations.14 CFR Subpart E (91.401

- 91.417)

- Maintenance, Preventive Maintenance, and

Alterations

The regulation provides that the operator is primarily responsible for maintaining the aircraft in an airworthy condition, including compliance with Parts 39 and 43. Para graphs 91.407 and 91.409 require that the aircraft be "approved for return to service by a person authorized under 43.7" after maintenance and inspection. Section 91.409(a)(2) requires an annual inspection for the issuance

of an airworthiness certificate. Section 91.417(a) requires the owner or operator to keep records showing certain maintenance work that has been accomplished by certificated mechanics, under Part 43, or licensed pilots and records of approval of the aircraft for return to service.

ENSIGN proposes that the maintenance of the eBee will be accomplished by the owner/operator according to the maintenance manual, provided by SenseFly. ENSIGN requests the FAA treat the eBee training program as proprietary under 14 C.F.R. 11.35(b) and not includ e this document in the public docket.

An equivalent level of safety will be achieved because the eBee is small in size, it is not a complex mechanical device, it will carry no external payload, and it will operate only in restricted predetermined areas. M oreover, the operator is the person most familiar with the aircraft and is best suited to maintain the aircraft in an airworthy condition and to ensure an equivalent level of safety. Finally, before every flight, the eBee runs automatically a sequence of p re

- flight tests to make sure that every sensor and every critical part is running properly. If a problem is detected,

the eBee will not be able to be switched

- on and a message error is displayed on the main screen of

t he flight management software . The op erator can then refer to the maintenance manual to troubleshoot this issue. Several parts of the eBee are easily interchangeable (propellers, wings), which allows the operator to make sure the wings and propulsion system are always airworthy

when a mission is initiated.
