Dear Mr. Lindberg :

This letter is to inform you that we have granted your petition for an amendment. It explains

the basis for our decisi on, describes its effect, and lists any changes to the original conditions

and limitations.

By letter dated September 1, 2015

, you petitioned the Federal Aviation Administration (FAA)

on behalf of Mosher Thomas LLC (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 Pre cisionHawk Lancaster Mk−III

.

In your petition, you indicate that th ere 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 the 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, we ight, speed, and limited operating area associated with the aircraft and its operation, the Secretary of Transportation2

has determined that this aircraft meets the conditions of Section 333. Therefore, the FAA

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

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

Our Decision

The FAA has determined that the justification for the issuance of Exemption No. 12853 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 oper ations.

The operator shall add this amendment to its original exemption.

Conditions and Limitations

All conditions and limitations within Grant of Exemption No. 12853 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 exemption.

1. Operations authorized by this grant of exemption are limited to the Blad e 350 QX

, Walkera Tali H500, and PrecisionHawk Lancaster Mk−III when weighing less than

55 pounds including payload. Proposed operations of any other aircraft w ill require a new petition or a petition to amend this exemption.

T his exemption terminates on September 30, 2017 , unless sooner superseded or rescinded.

Sincerely,
