II. D ESCRIPTION OF P ROPOSED O PERATION

NBMS seeks an exemption pursuant to Secti on 333 of the Reform Act to ut ilize aerial image georeferenced technology coupled with LiDAR processes to develop a densified point

cl oud that can be used in an unlimited amount of engineering applications. In addition, the UAS

will record high definition video imagery to ensure safe and effective mining and/or blasting

processes.

Specific examples of NBMS ' use of the UAS include:

● Determining High wall slope stability

● Proper burdening or confinement of blast charges

● Blast analysis to insure efficient and safe performance

● Environmental effects tracking

● Reclamation topographical measurement

● Storage pi le inventories

● Original topographical recording

● Safe inspection of remote sectors of the processes.

In addition, NBMS ’ use of unmanned aerial technology will be primarily in completely controlled mine permit areas or strictly guarded m anufacturing facilities. All persons within the flight areas are associated with the mining or manufacturing process. The general public will not be effected by our operations.

NBMS is committed to maintaining the highest standards of flight sa fety. All UAS operations will be performed in accordance with the accompanying NBMS operating documents, and in accordance with the requirements of an applicable C ertificate of Authorization ("C OA ")

. Among other things, and as detailed in the o perating documents, all UAS operations will occur in uncontrolled airspace, within visual line

- of

- sight (VLOS) of the pilot and visual observer, andU.S. Department of Transportation September 22, 2015 Page 4 Salans FMC S NR Denton
McKenna Long

dentons.com

will be limited to daytime VFR conditions. Moreover, NBMS ' operating documents incorporate

redun dant safeguards to enhance safety.

The proposed operations in this Petition for Exemption are not new or novel to the FAA. The FAA has previously issued grants of exemption to use small UAS for aerial data collection in support of similar inspection, surv ey and aerial imaging activities: See e.g.

,

Exemption No. 12663 to Seiler Instrument Inc. for agricultural and mining surveying
(Docket No. FAA

- 201 5

- 2130 );

The low

- risk UAS operations proposed by NBMS in this Petition for Exemption fall

square ly within the category of aerial data collection that has been subject to previous approval.

III. R ELEVANT S TATUTORY A UTHORITY

This Petition for Exemption is submitted pursuant to Section 333(a) through (c) of the Reform Act. Congress has directed the FAA "to safely accelerate the integration of civil unmanned aircraft systems into the national airspace system." Pursuant to Section 333 of the Reform Act, the FAA Administrator is to permit unmanned aircraft systems to operate in the

NAS where it is safe to do s o based on the following considerations:

 The UAS's size, weight, speed and operational capability;

 Operation of the UAS in close proximity to airports and populated areas; and

 Operation of the UAS within the visual line of sight of the operator.

Additional ly, the FAA Administrator has general authority to grant exemptions from the agency's safety regulations and minimum standards when the Administrator decides a requested exemption is in the public interest. See 49 U.S.C. § 106(f) (defining the authority of the Administrator); 49 U.S.C. § 44701(f) (permitting exemptions from §§ 44701(a), (b) and §§ 44702

– 44716, et seq. ). A party requesting an exemption must explain the reasons why the exemption: (1) would benefit the public as a whole, and (2) would not ad versely affect safety (or how it would provide a level of safety at least equal to the existing rules). See 14 C.F.R. § 11.81 (petitions for exemption).

A. 91.9(c), 45.23(b) and 45.27(a): Aircraft Marking and Identification Requirements

NBMS seeks an exemption from the aircraft marki ng and identification requirements contained in 14 C.F.R. §§ 91.9(c), 45.23(b) and 45.27(a).

● 14 C.F.R. § 91.9(c), Civil Aircraft Flight Manual, Marking and Placard Requirements, provides that:

No person may operate a U.S.

- registered civil aircraft unless t hat aircraft is identified in accordance with Part 45 of this chapter.

● 14 C.F.R. § 45.23(b), Markings of the Aircraft, states:

When marks include only the Roman capital letter "N" and the registration number is displayed on limited, restricted or light

- spo rt category aircraft or experimental or provisionally certificated aircraft, the operator must also display on that aircraft near each entrance to the cabin, cockpit, or pilot station, in letters not less than 2 inches nor more than 6 inches high, the word s "limited," "restricted," "light

- sport, "experimental," or "provisional," as applicable.

● 14 C.F.R. § 45.27(a), Rotorcraft, states:

Each operator of a rotorcraft must display on that rotorcraft horizontally on both surfaces of the cabin, fuselage, boom, or tail the marks required by § 45.23.

In prior grants of exemption under Section 333 of the Reform Act, the FAA determined that exemption from these requirements was warranted provided that the aircraft "have identification (N

- Number) markings in accordanc e with 14 C.F.R Part 45, Subpart C if the markings are as large as practicable." 3 All UAS flown by NBMS will bear N

- number markings that are as large as practicable in accordance with 14 C.F.R. Part 45, Subpart C. 4

B. 91.405(a), 91.407(a)(1), 91. 409(a)(1) and (2); 91.417(a) and (b): Maintenance Inspections

NBMS seeks an exemption from the maintenance inspection requirements contained in 14 C.F.R. § 91.405(a), 91.407(a)(1), 91.409(a)(1) and (2); 91.417(a) and (b). These regulations

spec ify maintenance and inspection standards in reference to 14 C.F.R. Part 43. 5 An exemption from these regulations is needed because Part 43 and these sections only apply to aircraft with an

airworthiness certificate, which the UAS to be operated under this grant of exemption will not

have.

An equivalent level of safety will be achieved because maintenance and inspections will be performed in accordance with the operating documents and any required manufacturer Safety or Service Bulletins. Further, as requi red by the operating documents, the Pilot in Command (PIC) will conduct a pre

- flight inspection of the UAS and all associated equipment to account for all discrepancies and/or inoperable components. Maintenance will be performed and verified to address any conditions potentially affecting safe operation of the UAS and no flights will occur unless, and until, all flight critical components of the UAS have been found to be airworthy and in a condition safe for operation. A functional test flight will be condu cted following the replacement of any flight

- critical components. As required by the operating documents, the PIC who conducts the functional test flight will make an entry in the UAS aircraft records of the flight.

The operating documents also include requirements to follow the UAS manufacturer’s maintenance, overhaul, replacement, inspection, and life limit requirements for the aircraft and aircraft components. Moreover, the operating documents also include procedures to document

and maintain a record of the UAS maintenance, preventative maintenance, alterations, status of replacement/overhaul component parts, and the total time in service of Petitioner's UAS. As a whole, the maintenance and inspection procedures required by Petitioner's operating docum ents ensure that an equivalent or higher level of safety will be achieved.

C. 61.23(a) and (c), 61.113, 61.101(e)(4) and (5), 61.315: Private, Recreational and Sport Pilot Medical Certificate, Privileges and Limitations

NBMS seeks exemption from th ese sections, which restricts private, recreational or sport pilot certificate holders from flying aircraft for compensation or hire, and would also require a Class II Medical Certificate. The purpose of Part 61 is to ensure that the skill and competency o f any PIC matches the airspace in which the PIC will be operating, as well as requiring certifications if the private pilot is carrying passengers or cargo for hire. In this case, while the UAS will be operated as part of a commercial operation, it carries neither passengers nor cargo.

In the Grant of Exemption No. 11062 to Astraeus Aerial 6 , the FAA determined that the unique characteristics of UAS operation outside of controlled airspace did not warrant the

additional cost and restrictions attendant with requiring the PIC to have a Commercial Pilot Certificate and Class II Medical Certificate. The fulfillment of the additional requirements for a private pilot to become qualified as a commercial pilot would not lead to any additional safety

benefits when U AS operations are involved.

More recently, the FAA determined that holders of recreational and sport pilot certificates would also have adequate aeronautical knowledge to pilot a UAS. Accordingly,

6 FAA Docket No. FAA

McKenna Long

dentons.com

because these individuals would also be subject to secur ity screening by the Department of Homeland Security (DHS), the FAA determined that holders of recreational and sport pilot certificates would be qualified to serve as the PIC for UAS operations. 7

D. 91.7(a): Civil Aircraft Airworthiness

Inasmuch as there will be no airworthiness certificate issued for the UAS, NBMS seeks an exemption from 14 C.F.R. § 91.7(a), which requires that a civil aircraft be in an airworthy condition to be operated. While Petitioner’s UAS will not have an airworthiness ce rtificate, the FAA has determined that for the purposes of this exemption the pilot may determine the aircraft is in an airworthy condition prior to flight. The operating documents contain procedures, which

allow the PIC to determine whether the aircraft i s in a condition safe for flight, and an exemption from § 91.7(a) is therefore warranted.

E. 91.9(b)(2): Civil Aircraft Flight Manual in the Aircraft and 91.203(a) and (b): Carrying Civil Aircraft Certification and Registration

Title 14 C.F.R. § 91.9(b)(2 ) and § 91.203(a) and (b) require the operator to carry

airworthiness documents and other aircraft manuals onboard the aircraft.

Pursuant to 14 C.F.R. § 91.9(b)(2):

(b) No person may operate a U.S.

- registered civil aircraft

–

... (2) For which an Airplane o r Rotorcraft Flight Manual is required by § 21.5 of this chapter, unless there is available in the aircraft a current approved Airplane or Rotorcraft Flight Manual, approved manual material, markings, and placards, or any

combination thereof.

Pursuant to 1 4 C.F.R. § 91.203(a) and (b):

(a) Except as provided in § 91.715, no person may operate a civil aircraft unless it has within it the following:

(1) An appropriate and current airworthiness certificate...

(b) No person may operate a civil aircraft unless the airworthiness certificate required by paragraph (a) of this section or a special flight authorization issued under § 91.715 is displayed at the cabin or cockpit entrance so that it is legible to passengers or crew.

Given the small size and configuration of the UAS, it would be impossible to keep airworthiness documents and other aircraft manuals on board the UAS because there is simply no room and the UAS has no cabin or cockpit.

In an FAA Office of Chief Counsel's Opinion dated August 8, 2014, and prepare d by Dean E. Griffith, Attorney, AGC

- 220, it was acknowledged that the intent of 14 C.F.R. 91.9(b) and 91.203(a) and (b) is met if the pilot of the unmanned aircraft has access to the UAS flight manual, registration certificate, and other required document s from the ground control station from which he or she is operating the aircraft. 8 As this FAA Office of Chief Counsel Opinion clarifies, the intent of the rule is to ensure the pilot has access to these key documents during flight. Therefore, an equivalen t level of safety will be achieved by ensuring that the pilot has access to the documents at the ground control station from which he or she is piloting the UAS. 9

F. 91.103: Preflight Action

Petitioner seeks an exemption from 14 C.F.R. § 91.103, which req uires a PIC to become familiar with specific information before each flight, including information contained in the

FAA

- approved Flight Manual on board the aircraft. While the PIC will be familiar with all information necessary to safely conduct the flight , an exemption is requested to the extent that an

FAA

- approved Flight Manual is required.

Adherence to the requirements in the operating documents will ensure that the UAS is in an airworthy condition prior to flight. The PIC will perform a series of check lists designed to identify any defects or inoperable components, which cover pre

- flight, take

- off, landing and

post

- flight procedures. The PIC will also be required to review weather, flight requirements, battery charge, landing and takeoff distance, UA pe rformance data, and contingency landing

areas

— before initiation of flight. Petitioner's operating documents will be kept at the ground control station and will be accessible to the PIC at all times while operating the UAS.

G. 91.109(a): Flight Instruction

Pet itioner seeks an exemption from 14 C.F.R. § 91.109(a), which provides in pertinent part that "[n]o person may operate a civil aircraft (except a manned free balloon) that is being used for flight instruction unless that aircraft has fully functioning dual controls." UAS and remotely piloted aircraft, by their design, do not have functional dual controls. Instead, flight control is accomplished through the use of a device that communicates with the aircraft via radio communications. Accordingly, an exemption will be required for the flight instruction requirements of 14 C.F.R. § 91.109(a).

Given the size and speed of the UAS that Petitioner intends to use, an equivalent level of safe training can still be achieved without dual controls because no pilot or pa ssengers are aboard the UAS, and as required by the operating documents, all persons will be a safe distance away in the event that the UAS experiences any difficulties during flight instruction. Moreover, all flight training will be conducted in controlle d and sterile environment. As a whole, the procedures provided for in the operating documents ensure that UAS flight instruction can be performed safely.

H. 91.119(c): Minimum Safe Altitudes Over Other Than Congested Areas

NBMS requests an exemptio n from the minimum safe altitude requirements of 14 C.F.R. § 91.119(c). 10 Section 91.119 prescribes the minimum safe altitudes under which aircraft may not operate, including 500 feet above the surface and away from any person, vessel, vehicle, or

structure in non

- congested areas. See 14 C.F.R. § 91.119(c).

An exemption is required because the proposed UAS operations will normally need to occur below 400 feet AGL. Additionally, due to the nature of the proposed operations, the PIC and/or Observers may need to be less than 500 feet away from the UAS. Compared to flight operations with rotorcraft weighing far more than the maximum weights proposed herein, and given the lack of flammable fuel with the UAS, any risk associated with these operations is far

less t han those that presently exist with conventional aircraft.

An equivalent level of safety will be achieved given the size, weight, and speed of the UAS, as well the controlled location where the operations will occur. In order to avoid any risk

to manned a ircraft, flight operations will be restricted to below 400 feet AGL. As set forth in the operating documents, the UAS will be operated in a controlled environment, and all flights will occur at a lateral distance of at least 500 feet from nonparticipating persons, unless that person is in a position where he or she is shielded from the UAS and any possible debris resulting from UAS failure. Procedures will be in place to ensure flight operations can be safely terminated if a nonparticipating person within 5 00 feet of the UAS leaves a shielded position. Further, UAS operations will occur at least 500 feet away from vehicles or structures unless the property owner/controller has granted permission and the PIC has made a safety assessment of the risk of

operat ing closer to those objects, and operations near the PIC or Observer will not present an undue hazard per § 91.119(a). Adherence to these restrictions in NBMS ' operating documents will ensure the proposed operations can be conducted without comp romising safety to persons or property on the ground.

10 Relief from § 91.119(a) will not be necessary because Petitioner will be able to perform an emergency landing without undue hazard to persons or property on the ground in the event of a failure. Petitioner's proposed UAS operations will not occur over congested areas, and therefore an exemption from § 91.119(b) will not be

necessary. See e.g

I. 91.121: Altimeter Settings

To the extent necessary for NBMS to conduct the proposed operations, Petitioner requests an exemption from 14 C.F.R. § 91.121, which requires a person operating an aircraft to maintain cruising altitude or flight level by reference to an altimeter that is set to the elevation of the departure airport or barometric pressure.

The FAA has stated that an equivalent level of safety to the requirements of 14 C.F.R. §

9 1.121 can be achieved in circumstances where: (1) the UAS will be operated 400 feet AGL or below, (2) within VLOS, (3) where GPS based altitude information is relayed in real time to the operator at a ground

- based on

- screen display and, (4) where prior to each flight, a zero altitude initiation point is established for the PIC to confirm accuracy of the onboard GPS.

The UAS that Petitioner intends to use for performing the proposed operations meet all these operational characteristics. Moreover, the operati ng documents require the PIC to calibrate the aircraft's GPS compass prior to each flight operation. As the FAA has determined in circumstances similar to this Petition for Exemption, Petitioner's UAS and the safety mitigation procedures contained in the o perating documents, ensure that an equivalent level of safety will be achieved, and a grant of exemption to the requirements of § 191.121 is therefore appropriate.

NBMS requests an exemp tion from 14 C.F.R. § 91.151(a)'s fuel requirements for flight in Visual Flight Rules (VFR) conditions. Section 91.151 states:

(a) No person may begin a flight in an airplane under VFR conditions unless (considering wind and forecast weather conditions) th ere is enough fuel to fly to the first point of intended landing and, assuming normal cruising speed

–

(1) During the day, to fly after that for at least 30 minutes; or

(2) At night, to fly after that for at least 45 minutes.

Here, the technological limit ations on UAS battery power means that no meaningful flight operations can be conducted while still maintaining a 30

- minute battery reserve. An exemption from the fuel requirements of 14 C.F.R. § 91.151(a) is therefore required.

The FAA has previously gra nted relief from the fuel requirements of § 91.151(a) for flight in daytime VFR conditions in circumstances similar to those presented in this Petition for Exemption. 11 In Exemption No. 11213 to Aeryon Labs, Inc. 12 , the FAA determined that a requirements pro hibiting the PIC from beginning a UAS flight unless (considering wind and

forecast weather conditions) there was enough available power for UAS to operate for the intended operational time and to operate after that for at least five minutes or with the res erve power recommended by the manufacturer if greater, would ensure an equivalent level of safety to the fuel requirements of § 91.151(a). 13 Petitioner's operating documents impose this same requirements and an exemption from § 91.151(a)'s fuel requirements for flight in VFR conditions is therefore appropriate.

VI. D RUG AND A LCOHOL P ROGRAM

NBMS has established policies to ensure that no person may participate in UAS flight operations if they are under the influence of alcohol or any drug.

VII. P UBLIC I NTEREST

The public interest will be served by granting NBMS ' Petition for Exemption. Congress has established a national policy that favors early integration of UAS into the National Air Space (NAS) in controlled, safe working environments such as those proposed in this Petition. Granting this Petition for Exemption helps fulfill Congress' goal in passing Section 333(a) through (c) of

the Reform Act

— the FAA Administrator's assessment of whether certain UAS may operate safely in the NAS before com pletion of the statutorily required rulemaking.

The proposed UAS operations in this Petition for Exemption significantly improve safety and reduce risk by alleviating the public's exposure to danger associated with traditional aerial

data collection metho ds, namely, full size fixed

- wing aircraft and rotorcraft. The UAS that

NBMS intends to use are light weight, are battery powered, and create no emissions. Moreover, in the unlikely event that one of Petitioner's UAS crash, there is no fuel to i gnite and explode. Any accident involving Petitioner's small lightweight UAS will present significantly less danger to the pilot and other individuals on the ground than one involving a full size helicopter.

VIII. P RIVACY

The proposed operations will be conduc ted in accordance with applicable federal, state, or local laws regarding privacy. NBMS will not conduct flight operations over property that it does not own or control without the prior consent and knowledge of the property owner.

IX. F EDERAL R E GISTER S UMMARY

Pursuant to 14 C.F.R. Part 11, the following summary is provided for publication in the

F EDERAL R EGISTER , should it be determined that publication is needed:

Petitioner seeks an exemption from the following rules in Title 14 of the Code of Federal Regulations:

45.23(b); 45.27(a); 61.23(a) and (c); 61.113; 61.101(e)(4) and (5); 61.315; 91.7(a); 91.9(b)(2); 91.9(c); 91.103; 91.109(a); 91.119(b); 91.121; 91.151(a); 91.203 (a) & (b); 91.405(a); 91.407(a)(1); 91.409(a)(1) & (2); 91.417 (a) & (b).

The exemption will enhance safety by reducing risk to the general public and property owners from the substantial hazards associated with using conventional fixed

- wing aircraft or

rotorcraft for aerial data collection.

X. C ONCLUSION

The proposed operat ions in this Petition for Exemption satisfy the criteria articulated in Section 333 of the Reform Act and the FAA has issued grants of exemption in circumstances similar in all respects to those presented by NBMS in this Petition for Exemption. In consideration of the foregoing, this Petition for Exemption provides the FAA with all the necessary justification for granting the requested exemptions allowing NBMS to operate small UAS for the purpose of aerial data collection.
