 Exemption No. 10261B 

 Regulatory Docket No. FAA-2005-20297 

Mr. John Torrance 

Pilot 

St. Bernard Parish Mosquito Control 

8201 West Judge Perez Drive 

Chalmette, LA 70043 

Dear Mr. Torrance: 

This letter is to inform you that we have granted your petition to extend Exemption 

No. 10261, 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 February 6, 2015, you petitioned the Federal Aviation Administration (FAA) 

on behalf of St. Bernard Parish Mosquito Control (SBPMC) for an extension of Exemption 

No. 10261, as amended. That exemption from § 137.53(c)(2) of Title 14, Code of Federal 

Regulations (14 CFR) allows pilots employed by SBPMC to conduct aerial applications of 

insecticide materials over congested areas from a Britten-Norman BN2A-26 (Registration No. 

N706MC, Serial No. 883) that is not equipped with a device capable of jettisoning at least 

one-half of the aircraft’s maximum authorized load of agricultural materials within 45 

seconds. 

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 exemption would not set a precedent, and any 

delay in acting on this petition would be detrimental to SBPMC.

Our Decision 

The FAA has determined that the justification for the issuance of Exemption No. 10261, 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 St. Bernard Parish Mosquito Control 

(SBPMC) an exemption from 14 CFR § 137.53(c)(2) to allow pilots employed by SBPMC to 

conduct aerial applications of insecticide materials over congested areas from a BrittenNorman BN2A-26 (Registration No. N706MC, Serial No. 883) that is not equipped with a 

device capable of jettisoning at least one-half of the aircraft’s maximum authorized load of 

agricultural materials within 45 seconds, subject to the following conditions and limitations. 

Conditions and Limitations 

1. This exemption is limited to the Britten-Norman BN2A-26 (Registration 

 No. N706MC, Serial No. 883). 

2. The authority of this exemption is to be used only in conjunction with conducting 

aerial agricultural operations. 

3. During spray operations, the aircraft operated in conjunction with this exemption is 

limited to a maximum gross weight that will ensure a single-engine climb performance 

capability of at least 200-feet-per-minute positive rate at the prevailing density 

altitude. Under no condition will the aircraft’s gross weight exceed the maximum 

takeoff gross weight specified in the FAA-approved airplane flight manual. 

4. Prior to each flight, a document must be prepared showing the weight and balance 

calculations and the altitude performance for the forecast operating density altitude. 

The document must be retained for at least 30 days and must be presented to any 

representative of the Administrator upon request. 

5. Each pilot in command (PIC) of the aircraft operated under this exemption must have 

a total of at least 1,200 hours of flight time as pilot, including at least 200 hours PIC 

time in BN2A-26 aircraft, 50 flight-hours of which must have been in agricultural 

applications. 

6. A copy of this exemption must be provided to each PIC who operates under the terms 

of this exemption. 

7. 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 BN2A-26 aircraft. A 

record of this instruction must be made available by the PIC to any representative of 

the Administrator upon request.

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

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

Sincerely, 

/s/
