Exemption No. 11676 Regulatory Docket No. FAA

– 20 15

– 0568

Mr. Atul Khanzode Director of Construction Technologies DPR Construction 1450 Veterans Boulevard Redwood City

, CA 94063

Dear Mr. Khanzode :

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 February 10, 2015 , you petitioned the Federal Aviation Administration (FAA) on behalf of DPR Construction ( hereinafter petitioner or operator ) for an exemption

. The exemption would all ow the petitioner to operate an unmanned ai rcraft system (UAS) to conduct aerial imaging for safety and monitoring of secured and controlled environment construction sites

. See Appendix A for the petition submitted to the FAA des cribing the proposed operations and the regulations that the petition er 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 detrimen tal to the petitioner

.

Airworthiness Certification

The UAS proposed by the petitioner is a Skycatch.

The petitioner requested relief from 14 CFR part 21, C ertification procedures for products and parts, Subpart H

— Airworthiness Certificates

. In accordance with the statutory criteria2

provided in Section 333 of P ublic 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

, C ertification procedures for products and parts, Subpart H

— Airworthiness Certificate s , 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 collection

. The FAA has issued grants of exemption in circumstances similar in all material respects to those presented in your petition. In Grants of Exemption No s

. 11062 to Astraeus Aerial ( see Docket No. FAA−2014−0352), 11109 to Clayco, Inc. ( see Docket No. FAA

− 20 14

− 0507), 11112 to VDOS Global, LLC ( see Docket No. FAA−2014−0382), and 11213 to Aeryon Lab s , 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 peti tioner 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 i nterest.

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. Ther efore, pursuant to the authority contained in 49 U.S.C. 106(f), 40113, and 44701, delegated to me by the Administrator, DPR Construction 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 operate a UAS to perform aerial data collection

. This exemption is subject to the conditions and limi tations listed below.

Conditions and Limitations

In this grant of exemption, DPR Construction is hereafter referred to as the operator.3

Failure to comply with any of the conditions and limitations of this grant of exemption will be grounds for the immediate suspension or rescission of this exemption.

1. Operations authorized by this grant of exemption are limited to the Skycatch 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 un aided 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 ;

e lectronic messaging or texting is not permitted d uring 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.

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 operati ons 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 mu st 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 rev ised documents to the Administrator or any law enforcement official upon request. The4

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 upda te 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 FA A’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 conducti ng 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 haz ard 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 prohibi ted 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 fo r 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 pil ot 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 Col u mbia, Puerto Rico, a territory, a possession, or the Federal G overnment. The PIC must also meet the flight revi ew 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 c onsistent 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 VOs5

(traini ng, 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 traini ng, proficiency, and experience

- building flights, all persons n ot 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 symbo l as denoted on the current FAA

- published aeronautical chart, unless a letter of agreement with that airport’s management is obtained or o therwise 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 sign al, the UA must return to a
pre

- determined location within the pr ivate or controlled

- acces s 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 5 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 cond ucted in accordance with an ATO

- issued COA. The exemption holder may apply for a new or amended COA if i t 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 be as large as practicable.6

23. Documents used by the operator to ensure the safe operation and flight of the UAS and any documents required under 14 CFR §§ 91.9 a nd 91.203 must be available to the PIC at the Ground Control Station of the UAS any time the aircraft is operating. These documents must be made available to the Administrator or any law enforcement official upon request.

24. The UA must remain clear and giv e way to all manned aviation operations and activities at all times.

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

26. All Flight operations must be conducted at least 500 feet from all nonparticipating persons, vessels, vehicle s, 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, vehic les 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 control led

- 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.

28. Any incident, accident, or flight operation that transgresses the lateral or vertical boundaries of the operational area as defined by the applicable COA must be reported to the FA A's UAS Integration Office (AFS− 80) within 24 hours. Accidents must be reported to the National Transportation Safety Board (NTSB) per instructions contained on the NTSB Web site: www.ntsb.gov

. If this exemption permits operations for the purpose of closed

- set motion picture and television filming and production, the following additional conditions and limitations apply.

29. The operator must have a motion picture and television operations manual (MPTOM) as documented in this grant of exemption.7

30. At least 3 days before aerial filming, the operator of the UAS affected by this exemption must submit a written Plan of Activities to the local Flight Standards District Office (FSDO) with jurisdiction over the a rea of proposed filming. The 3

- day notification may be waived with the concurrence of the FSDO. The plan of activities must include at least the following:

a. Dates and times for all flights; b. Name and phone number of the operator for the UAS aerial filming conducted under this grant of exemption;

c. Name and phone number of th e person responsible for the on

- scene operation of the UAS; d. Make, model, and serial or N− Number of UAS to be used;

e. Name and certificate number of UAS PI Cs involved in the aerial filming; f. A statement that the operator has obtained permission from property owners and/or local officials to conduct the filming production event; the list of those who gave permission must be made available to the inspector upon request; g. Signature of exemption holder or representative; and h. A description of the flight activity, including maps or diagrams of any area, city, town, county, and/or state over which filming will be conducted and the altitudes essential to accomplish the operation.

31. Flight operations may be conducted closer than 500 feet from participating persons consenting to be involved and necessary for the filming production, as specified in the exemption holder’s MPTOM.

Unless otherwise specified in this grant of e xemption, the UAS, the UAS PIC, and the UAS operations must comply with all applicable parts of 14 CFR including, but not limited to, parts 45, 47, 61, and 91.

This exemption terminates on May 31, 2017 , unless sooner superseded or rescinded.

Sincerely,

Re: Exemption Request Section 333 of the FAA Reform Act and Part 11 of the Federal Aviation Regulations from 14 CFR 61.113 (a) & (b); 91.103(b); 91.119; 91.121; 91.151(a); 91.405 (a); 91.407(a) (1); 91.409 (a) (2); 91.417 (a) & (b).
Dear Sir or Madam:

Pursuant to Section 333 of the FAA Modernization and Reform Act of 2012 (the Reform Act) and 14 C.F.R. Part 11, DPR Construction
, an engineering and construction
compan y, hereb y applies for an exemption from the listed Federal Aviation Regulations (“FARs”) to allow commercial operation of its Small Unmanned Aircraft Sy stems (“ sUAS ”) for aerial imaging for safet y and monitoring of sec ured and controlled environment construction sites , 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 and the attached Fligh t Manual , 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 safet y enhancements to the already best practices safet y protoc ols followed b y DPR at each one of its construction sites. Approval of this exemption would thereb y enhance safet y and fulfill the Secretary

of Transportation’s (the FAA Administrator’s) responsibilities to “...establish requirements for the safe operation of such aircraft s ys tems in the national airspace sy stem.” Section 333 (c) of the Reform Act. The name and address of the applicant is:

**I. STATUTORY AUTHORITY FOR EXEMPTIONS**  The Federal Aviation Act expressly grants the FAA authority to issue exemptions. This statutory

authorit y i ncludes exempting civil aircraft, as the term is defined under §40101 of the Act, including s UAS s , 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 an y 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 S ecretary in determining whether

s UAS may

operate in the National Airspace Sy stem (NAS) without creat ing a hazard to the user, the public, or a threat to national security . I f the Secretary determines that a

s UAS “may

operate safely

in the national airspace sy stem, the Secretary shall establish requirements for the safe operation of such aircraft in the national airspace sy stem.” Id

. §333(c).

DPR ’s s UAS are multirotor vehicles , weighing 10 or fewer lbs. including
pay load. They

operate under normal conditions at a speed of no more than 50 knots and have the capability

to hover, and move in the vertical and horizontal plane simultaneously

. The sUAS will operate only in the Pilot’s visual line of sight at all times and will operate onl y within the sterile area described in the Confidential Sky catch Flight Manual, attached as Exhibit 1 (hereinafter “the Manual”). Such operations will insure that the s UAS will “not create a hazard to users of the national airspace s ys tem or the public.” Reform Act Section 333 (b).
Given the small size of the sUAS involved and the restricted and sterile environment within which they will operate, our application falls squarel y within the zone of safet y (an equival ent level of safety ) in which Congress envisioned that the FAA must, by exemption, allow commercial operations of s UAS to commence immediately

. Also due to the small size of the s UAS and the low altitudes and restricted areas in which the s UAS will operate , approval of the application presents no national security issue. Given the clear direction in Section 333 of the Reform Act, the authorit y contained in the Federal Aviation Act, as amended; the strong equivalent level of safet y surrounding the proposed operations, and the significant public benefit, including enhanced s afety , the grant of the requested exemptions is in the public interest. Accordingl y, DPR respectfully requests that the FAA grant the requested exemption without delay

.

**II. PUBLIC INTEREST** 3 This exemption application is expressly submitted to fulfill Con gress’ 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 s ys tems may operate safel y in the NAS before completion of the rulemaking required under Sec tion 332 of the Reform Act. By

granting an exemption the FAA will fulfill Congress’s intent of allowing UAS to operate with significant safet y precautions in low risk environments.
The use of s UAS on a construction site can significantly reduce the risk to workers of falls while inspecting, survey ing, or monitoring site progress. s UAS can inspect, photograph, and collect data on hard to get to areas that otherwise would require worker inspection. Falls a re a leading source of workplace fatalit y and injury on construction sites 1 , and reducing falls through s UAS use for site imaging could save workers lives. Additionally , s UAS could replace the use of helicopters and small aircraft to monitor sites. The s UAS we propose to fl y in this application are under five pounds, and

carr y no combustible material on board , as opposed to the much larger conventionally powered small aircraft

. Shifting to s UAS from helicopters presents a marked safet y increase for our workers and the public

. Lastl y, s UAS reduce the environmental impact by dramaticall y decreasing the
energy used for aerial imaging and data collection over a construction site. Our s UAS use rechargeable lithium i on batteries, as opposed to foss il fuels burned in operation of small aircraft that are man y hundreds of times heavier.

**III. EQUIVALENT LEVEL OF SAFETY** 

DPR 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 safet y to operations under the current regulatory

structure because the proposed operations represent a safety enhancement to the alrea dy safe protocols followed on construction sites and imaging and
survey ing operations conducted with helicopters and other conventional aircraft.

DPR will be bound by

the following limitations when conducting its s UAS operations under an FAA issued exempti on:
1. The s UAS will be less than 10 pounds. 2. Flights will be operated within visual line of sight of a pilot. 3. Maximum total flight time for each operational flight will be 30 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 30 minute limit. 4. Flights will normall y be operated at an altitude of 200 feet AGL, never exceedin g 400 feet AGL

.

1 “Commonly	Used	Statistics”,	Occupational	Safety	&	Health	Administration.	Available	at: https://www.osha.gov/oshstats/commonstats.html4

5. Any site within 5 miles of an airport will not be flown without notification and approval of the local FAA Flight Standards District Office (FSDO) and airport controller. 6. C rew for each operation will consist of the s UAS Pilot who will keep the s UAS within his visual line of sight at all times. 7. The s UAS P ilot will be trained in flight, operations, and safet y procedures as detailed in the Flight Manual

. 8. The s UAS will only

operate within a confined “Sterile Area” as defined in the Manual. Th e Manual also requires the establishment of a “Securit y Perimeter” for the flight operations area. 9. A briefing will be conducted in regard to the planned s UAS operations prior to each day ’s production activities. I t will be mandatory that all personnel who will be performing duties within the boundaries of the safety perimeter be present for this briefing. 10. All onsite personnel will consent to the UAS fl yover on site b y waiver, and t he operator will obtain additional verbal or written consent of all persons who will be allowed within 100 feet of the flight operation

. 11. Pilot will have been trained in operation of UAS s generall y and received up

- to

- date information on the particular UAS to be operated as required by Section F of the Manual. 12. Written and/or oral permission from the relevant propert y holders will be obtained. 13. All required permissions and permits will be obtained from territorial, state, county or city jurisdictions, including local law enforcement, fire, or other appropriate
go vernmental agencies. 14. If the s UAS 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 Security Perimeter and land.

**IV. 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

s UAS will not carry

a pilot or passenger s, the proposed operations can achieve the equivalent level of safet y of current operations by requiring the Pilot operating the aircraft to have (1) completed a s UAS flight training course of 100 hours before fly ing a

s UAS (See Section F of the Manual for more details) and (2) a Sport Pilot certificate

. The FAA has previousl y acknowledged in prior grants of exemption under Section 333 that a commercial pilot’s certificate was not necessary to operate a sUA S , but that the FAA could not waive the requirement for an FAA

- issued pilot’s license. A Sport Pilot certificate addresses the FAA’s requirement that the Pilot in command have the requisite training and understanding of the National Airspace Sy stem, and also ensures that the Pilot is registered with the F AA and will not pose a risk to national securit y. The Sport Pilot certificate also does not require the Pilot to undertake the additional cost and time of additional manned aviation flight time that the Private Pilot’s license requires and which will not t ranslate to skill or competency operating the sUA S

.5

Unlike a conventional aircraft that carries the pilot and passengers, the s UAS is remotely controlled with no living thing or cargo on board. Sky catch’s sUAS is also operated b y an autopilot, which grea tly reduces the danger of human error. The area of operation is controlled and restricted to hard hat areas , and all flights are planned and coordinated in advance as set forth in the Manual.

The sUAS to be operated hereunder is less than 10 lbs. fully lo aded, 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 Manual. Li ke other civil aircraft, operations under this exemption will be tightly contr olled and monitored by the operator, pursuant to the Manual’s requirements, and under the requirements and in compliance with local public safet y requirements, to provide securit y for the area of operation as is currentl y done on active construction sites

. The FAA will have advance notice of all operations.

The risks associated with the operation of the s UAS are therefore diminished from the level of risk associated with commercial operations contemplated b y Part 61 when drafted, and allowing operations o f the s UAS as requested with a Pilot who has met the minimum requirements stated in Section F of the Manual achieves the level of safet y contemplated by

14 C.F.R. §61.113 (a) & (b).

**14 C.F.R. 91.103 : Preflight Action** 

This regulation requires each pilot in command take certain actions before flight to

ensure the safet y of flight. An exemption is needed from this requirement as the Pilot will take separate preflight actions, including checking for weather conditions, che cking flight battery requirements, checking takeoff and landing distances, and all other actions in the Preflight Checklist in the Manual . These actions will provide an equivalent level of safet y. See Appendix A of the Manual.

**14 C.F. R. 91.119 : Minimum S**  **afe 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 the person operating the helicopter complies with an y route or alt itudes prescribed for helicopters b y the FAA. This exemption is for a multirotor craft that flies similarly to a helicopter, with vertical take off and vertical landing, which will ty picall y operate at altitudes of 200 AGL , so an exemption may be needed to allow such operations. The

s UAS will never operate at altitude higher than 4 00 AGL and will be in a restricted area with security

perimeter, where buildings and people will not be exposed to operations without their pre

- obtained consent. See Manual for detailed procedures

. The equivalent level of safet y will be achieved given the size, weight, speed of the s UAS as well as the location where it is operated. No flight will be taken without the permission of the propert y owner or local officials. Becau se of the advance notice to the propert y6

owner and an y onsite personnel as outlined in the Manual , all affected individuals will be aware of the planned flight operations. Unlike flight operations with aircraft or rotorcraft weighing far more than the maxi mum 10 lbs. proposed herein , our sUAS will not carr y flammable fuel. In addition, the low

- altitude operations of the sUAS will ensure separation between s UAS operations and the operations of conventional aircraft that must comply with Section 91.119.

**14 C.F.R. 91.121**  **: Altimeter Settings**

This regulation requires each person operating an aircraft to maintain cruising altitude b y 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 Manual and Safet y Check list, confirming t he 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 VFR conditions. Our s UAS is limited to operations in sterile and controlled environments as outlined in the Manual, 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 35 minutes of powered flight. To meet the 30 minute reserve requirement in 14 CFR §91.151, sUAS flights would be limited to approximately 5 minutes in length. Given the limitations on the s UAS ’s proposed flight area and the location of its proposed operations within a predeter mined area, a longer time frame for flight in day light or night VFR conditions is reasonable.

DPR 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 ope rate without compliance with FAR 91.151 (a)). Operating the small s UAS , in a tightly controlled area where only people and propert y owners or official representatives who have signed waivers will be allowed, with less than 30 minutes of reserve fuel, does not engender the ty

pe 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 greatl y reduce the utility for which the exemption will be granted.

A n equiva lent level of safety can be achieved by

limi ting 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 s ys tem and the Pilot ), whichev er happens first. This restriction would be more than adequate to return the sUAS to its planned landing zone from any where in its limited operating area.

Similar exemptions have been granted to other operations, including Exemptions 2689F, 5745, 10673, an d 10808.7

**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 section s and Part 43 appl y only to aircraft with an airworthiness certificate, these sections will not apply to DPR . Maintenance will be accomplished by the operator pursuant to the flight manual and operating handbook as referenced in the Manual. An equivalent le vel of safet y will be achieved because these small s UAS are very limited in size and will carry a small pay load and operate only in restricted areas for limited periods of time. If mechanical issues arise the s UAS can land immediately and will be operating from no higher than 400 feet AGL. As provided in the Manual, the Pilot will ensure that the s UAS is in working order prior to initiating flight, perform required maintenance, and keep a log of an y m aintenance performed. Moreover, the Pilot is the
person m ost familiar with the aircraft and best suited to maintain the aircraft in an airworth y condition to provide the equivalent level of safet y.

Pursuant to 14 C.F.R. Part 11, the following summary is provided for publication in the Federal Register, s hould it be determined that publication is needed:

Applicant seeks an exemption from the following rules: 14 C.F.R. §21, subpart H; 14 C.F.R 45.23(b);14 C.F.R. §§ 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 commerciall y a small unmanned vehicle (55lbs or less) in construction operations.

Approval of exemptions allowing commercial operations of sUAS in the cons truction industry enhances safet y while reducing risk

. Manned aircraft monitoring and survey ing 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 lb s. and powered b y 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 aircr aft flights.

The operation of small s UAS , weighing less than 10 lbs., conducted in the strict conditions outlined above, will provide an equivalent level of safet y supporting the grant of the exemptions requested herein, including exempting the applicant f rom 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 hel icopters operating in close proximity

to the ground and people.8

**Privacy**
All flights will occur over private or controlled access property with the property owner’s prior consent and knowledge. Im ages taken will be of individuals who have also consented to being filmed or otherwise have agreed to be in the area where aerial photograph y will take place.

Satisfaction of the criteria provided in Section 333 of the Reform Act of 2012

-- size, weight, speed, operating capabiliti es, controlled operating environment 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

s UAS in construction indu stry pursuant to the Manual appended hereto.
