 Exemption No. 10369B 

 Regulatory Docket No. FAA-2011-0660 

Mr. Malcom Williams 

Chief Pilot 

Vector Disease Control International, LLC 

1320 Brookwood Drive 

Little Rock, AR 72202 

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 the 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 International, 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 Regulations (14 CFR) allows Vector Disease 

Control 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. 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-23-250 
2 

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. 

Conditions and Limitations

operated by Vector Disease Control. 

2. This exemption is valid only when conducting agricultural aircraft operations under 

14 CFR part 137. 

3. Aircraft operated under this exemption are limited to a maximum gross weight that 

will ensure single-engine climb performance capability of at least 200-feet-per-minute 

positive rate at the prevailing density altitude. 

4. Prior to each flight, the operator or pilot-in-command (PIC) must prepare a document 

showing the weight and balance calculations and the single-engine climb performance 

for the forecast operating density altitude. The document must be retained by the 

operator for at least 30 days and presented to a representative of the Administrator of 

the FAA upon request. 

5. Each PIC of an aircraft operated under this exemption must have a total of at least 

1,200 hours of flight time as a pilot, including at least 200 hours PIC time in pistonpowered multiengine aircraft, 50 hours of which must have been in part 137 

operations. 

6. Vector Disease Control must provide a copy of this exemption to each PIC who 

operates under the terms of this exemption.

7. A copy of the exemption must be carried on the aircraft while conducting operations 

under the terms of this exemption. 

8. Prior to operating under this exemption, each PIC must have successfully completed 

flight instruction from an appropriately rated flight instructor on single-engine 

operations, performance, and handling characteristics of the Piper PA-23-250 or 

Cessna 402C model aircraft (as applicable). The instruction must be provided in each 

model of aircraft the PIC will operate under this exemption. A record of this 

instruction must be made available by the PIC upon request of any representative of 

the Administrator of the FAA. 

9. Vector Disease Control must provide a copy of this exemption to its part 137 

certificate-holding Flight Standards District Office. 

10. This exemption is not valid for operations outside of the United States. 

The Effect of Our Decision

September 30, 2017 unless sooner superseded or rescinded.
