Exemption No. 11835 Regulatory Docket No. FAA

– 20 15

– 1161

Ms. Mary B. Wohnrade, P.E. Principal Wohnrade Civil Engineers, Inc. 11582 Colony Row Broomfield, CO 80021

Dear Ms. Wohnrade :

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 March 27, 2015 , you petitioned the Federal Aviation Administration (FAA) on

behalf of Wohnrade Civil Engineers, Inc. ( hereinafter petitioner or operator ) for an exemption . The petitioner requested to operate an unmanned ai rcraft system (UAS) to

conduct site reconnaissance for public and private civil construction projects, including bridge inspections and aerial photography and videography

.

See Appendix A for the petition submitted to the FAA des cribing the proposed operations and

the regulations that t he petitioner seeks an exemption

.

The FAA has determined that good cause exists for not publishing a summary of the petition in the Federal Register because the requested exemption would not set a precedent, and any delay in acting on this petition would be detrimental to the petitioner

.

Airworthiness Certification

The UAS proposed by the petitioner is a DJI Inspire 1

.

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 criteria

### 2

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

— Airworthin ess Certificates , and any associated noise certification and testing requirements of part 36, is

not necessary.

The Basis for Our Decision

You have requested to use a UAS for aerial data collection 1



### . 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. Therefore, pursuant to the authority contained in 49 U.S.C. 106(f), 40113, and 44701, delegated to me by the Administrator, Wohnrade Civil Engineers, Inc. is gr anted 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 limitations listed

below.

1 Aerial data collection includes any remote sensing and measuring by an instrument(s) aboard the UA. Examples include imagery (photography, video, infrared, etc.), electronic measurement (precision surveying, RF analysis, etc.), chemical measurement (part iculate measurement, etc.), or any other gathering of data by

instruments aboard the UA.

Conditions and Limitations

In this grant of exemption, Wohnrade Civil Engineers, Inc. is hereafter referred to as

the operator.

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 DJI Inspir e 1 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 b e operated within visual line of sight (VLOS) of the PIC at all times. This requires the PIC to be able to use human vision unaided by any device other than corrective lenses, as specified on the PIC’s FAA

- issued airman medical certificate or

U.S. driver’ s license.

6. All operations must utilize a visual observer (VO). The UA must be operated within the visual line of sight (VLOS) of the PIC and VO at all times. The VO may be used to satisfy the VLOS requirement as long as the PIC always maintains VLOS

cap ability. The VO and PIC must be able to communicate verbally at all times ;

e lectronic 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

duratio n 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

ex emption, 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

### 4

limitations in this exemption and the procedures outlined in the operating documents, the conditions and limitations herein take precedence and must be followed. Otherwise, the operator must follow the procedures as outlined in its operating documents. The operator may upd ate 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 rev ised 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 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 fl ight characteristics, e.g.

, replacement of a flight critical component, must undergo a functional test flight prior to conducting further operations under this exemption. Functional test flights may only be conducted by a PIC with a VO and must remain at

least 500 feet from other people. The functional test flight must be conducted in such a manner so as to not pose an undue hazard to persons and property.

9. The operator is responsible for maintaining and inspecting the UAS to ensure that it is

in a condit ion for safe operation.

10. Prior to each flight, the PIC must conduct a pre

- flight inspection and determine the UAS is in a condition for safe flight. The pre

- flight inspection must account for all potential discrepancies, e.g.

, inoperable components, items , or equipment. If the inspection reveals a condition that affects the safe operation of the UAS, the aircraft is prohibited from operating until the necessary maintenance has been performed and the UAS is found to be in a condition for safe flight.

11. The operator must follow the UAS manufacturer’s maintenance, overhaul, replacement, inspection, and life limit requirements for the aircraft and

aircraft components.

12. Each UAS operated under this exemption must comply with all manufacturer safety bulletins.

13. Under this grant of exemption, a PIC must hold either an airline transport, commercial, private, recreational, or sport pilot certificate. The PIC must also hold a current FAA airman medical certificate or a valid U.S. driver’s license issued by a

state, the District of Col u mbia, Puerto Rico, a territory, a possession, or the Federal government. 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 consistent with how the UAS will be operated under this exemption, including evasive and emergency maneuvers and maintaining appropriat e 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 (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 c onducted during dedicated training sessions. During

traini ng, proficiency, and experience

- building flights, all persons not essential for flight operations are considered nonparticipants, and the PIC must operate the UA with appropriate distance from nonp articipants 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 otherwise permitted by a COA issued to the exemption holder. The letter of agreement with the airport management must be made available to the Administrator or any law enforcement official upon request.

17. The UA may not be operated less than 500 feet below or less than 2,000 feet horizontally from a cloud or when visibility is less than 3 statute miles from the PIC.

18. If the UAS loses commu nications or loses its GPS sign al, the UA must return to a

pre

- determined location within the pr ivate or controlled

- access property.

19. The PIC must abort the flight in the event of unpredicted obstacles or emergencies.

20. The PIC is prohibited from beginning a flight unless (considering wind and forecast weather conditions) there is enough available power for the UA to conduct the intended operation and to operate after that for at least five minutes or with the reserve power recommended by the manufacturer if greater.

21. Air Traffic Organization (ATO) Certificate of Waiver or Authorization (COA). All operations shall be cond ucted in accordance with an ATO

- issued COA. The exemption holder may apply for a new or amended COA if it intends to conduct operations th at cannot be conducted under the terms of the attached COA
