Exemption No. 10281A Regulatory Docket No. FAA-2011-0467

Mr. Guy M. Faget East Baton Rouge Parish Mosquito Control

2829 Lt. General Ben Davis Jr. Avenue Baton Rouge, LA 70807

Dear Mr. Faget:

This letter is to inform you that we have granted your petition to amend Exemption No. 10281. It explains the basis for our decision, describes its effect, and lists the revised

conditions and limitations.

The Basis for Our Decision

By subm ission received January 25, 2012, you petitioned the Federal Aviation Administration (FAA) on behalf of East Baton Rouge Parish Mosquito Abatement & Rodent Control (East Baton Rouge Mosquito Control) for an amendment to Exemption No. 10281. That exemption from § 137.53(c)(2) of Title 14, Code of Federa l Regulations (14 CFR) allows East BatonRouge Mosquito Control to conduct aerial applications of insecticide material from a BrittenNorman BN2B-21 (Registration No. N117MC, Serial No. 2178) without the aircraft being equipped with a device that is capable of jettisoning at least one-half of the aircraft’s maximum authorized load of agricultural materials within 45 seconds when operating over a congested area. The amendment you request would add an additional aircraft to the exemption (Registration No. N958MK, Serial No. 498).

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 amendment to the exemption would not set a2

precedent, and any delay in acting on this petition would be detrimental to East Baton Rouge Parish Mosquito Control.

Our Decision

The FAA has determ ined that the justification for the issuance of Exemption No. 10281, 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. 40113 and 44701, which the FAA Administrator has delegated to me, I grant your petition, subject to the following conditions

and limitations.

3. During spray operations, aircraft operated in conjunction with this exemption are 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;

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 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 BN2B-21 aircraft, 50 flight hours of which must have been in agricultural spray operations;

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 characteristics of the BN2B-21 aircraft. A record of this instruction must be made available by the PIC upon request of the Administrator; and
