Exemption No. 10369B Regulatory Docket No. FAA-2011-0660

Mr. Malcom Williams

Chief Pilot Vector Disease Control International, LLC

Dear Mr. Williams:

This letter is to inform you that we have granted your petition to extend and amend Exemption No. 10369, as amended. It explains th e basis for our decision, describes its effect,

and lists the conditions and limitations.

The Basis for Our Decision

By letter dated July 10, 2015, you petitioned the Federal Aviation Administration (FAA) on

behalf of Vector Disease Control Internati onal, LLC (Vector Disease Control) for an extension and amendment of Exemption No. 10369, as amended. That exemption from § 137.53(c)(2) of Title 14, Code of Federal Regul ations (14 CFR) allows Vector Disease Control to conduct aerial applications of insecticide materials for the purpose of mosquito control without the aircraft being equipped w ith the device specified in § 137.53(c)(2) when operating over a congested area. The amendment you request would delete Piper PA-23-250, registration No. N737WP, and add Piper PA -23-250, registration No. N203DM, and Piper PA-23-250, registration No. N68MW. The amended exemption would apply only to the following aircraft:

Registration No. Make/Model N415CC Piper PA-23-250 N40200 Piper PA-23-250 N203DM Piper PA-23-250 N68MW Piper PA-23-250 N31BB Piper PA-23-2502

N251RC Cessna 402C

In your petition, you indicate 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 the Federal Register because the requested extension and amendment of the exemption would not set a precedent, and any delay in acting on this petition would be detrimental to

Vector Disease Control.

Our Decision

The FAA has determined that the justification for the issuance of Exemption No.10369, as amended, remains valid with respect to this exemption and is in the public interest. Therefore, under the authority provided by 49 U.S.C. 106(f), 40113, and 44701, which the FAA Administrator has delegated to me, I grant Vector Disease Control International, LLC an exemption to conduct aerial applications of insecticide materials for the purpose of mosquito control without the aircraft being equipped with the device specified in § 137.53(c)(2) when operating over a congested area, subject to the following conditions and

limitations.
