Mr. Lyle Hardin CDG Engineers One Campbell Plaza, Suite 3A St. Louis, MO 63139

Dear Mr. Hardin :

This letter is to inform you that we have granted your petition for an amendment. It explains the basis for our decision, describes its effect, and lists any changes to the original conditions

and limitations.

By letter posted on Sep tember 17, 2015

, you petitioned the Federal Aviation Administration (FAA) o n behalf of CDG Engineers (hereinafter petitioner or operator) for an amendment to your current exemption . That exemption from §§ 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) of Title 14, Code of Federal Regulations (14 CFR) allows the petitioner to operate a UAS to perform aerial data collection

. You requested an

amendment to add the DJI Phantom 3

.

In your petition, you indic ate that there has been no change in the conditions and reasons relative to public interest and safety that were the basis for granting the original exemption.

The FAA has determined that good cause exists for not publishing a summary of the petition

in t he Federal Register because the requested amendment to the exemption would not set a precedent, and any delay in acting on this pe tition would be detrimental to the petitioner

. T he

unmanned aircraft authorized in the original grant are comparable in type, size, weight, speed and operating capabilities to those in this petition

.

Airworthiness Certification

In accordance with the statutory criteria provided in Section 333 of Public 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 Sect ion 333. Therefore, the FAA2

finds that relief from 14 CFR part 21, C ertification procedures for products and parts, Subpart H

— Airworthiness Certificates , and any associated noise certification and testing requirements of part 36, is not necessary.

Our De cision

The FAA has determined that the justification for the issuance of Exemption No. 11715 remains valid and is in the public interest. Therefore, under the authority contained

in 49 U.S.C

. 106(f), 40113, and 44701, delegated to me by the Administrator

, the operator is granted an amendment to add new aircraft to its UAS operations.

The operator shall add this amendment to its original exemption.

Conditions and Limitations

All conditions and limitations within Grant of Exemption No. 11715 remain in effect except as follows. Condition No. 1 has been updated to reflect the additional aircraft

.

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 ex emption.

1. Operations authorized by this grant of exemption are limited to the DJI Phantom 2

Vision and DJI Phantom 3 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

.

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

Sincerely,

/ s/
