Exemption No. 10041A Regulatory Docket No. FAA-2009-1239

Mr. Robert E. Zeng Director of Flight Operations

Omni Air International

3303 North Sheridan Road Tulsa, OK 74115

Dear Mr. Zeng:

This letter is to inform you that we have granted your petition to extend Exemption No. 10041. It transmits our decision, explains its basis, and gives you the conditions and limitations of the exemption, including the date it ends.

The Basis for Our Decision

By letter dated November 28, 2011, you petitioned the Federal Aviation Administration (FAA) on behalf of Omni Air International (Omni) for an exemption from §§ 121.613, 121.619(a), and 121.625 of Title 14, Code of Federal Regulations (14 CFR) to the extent necessary to dispatch airplanes under instrument flight rules when conditional language in a one-time increment of the weather forecast states that the weather at the destination, alternate airport, or both airports could be below the authorized weather minimums when other time

increments of the weather forecast state the weather conditions will be at or above the

authorized weather minimums.

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 Omni.2

Our Decision

The FAA has determined that the justification for the issuance of Exemption No. 10041, 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.

. Conditions and Limitations

1. Omni must list one additional alternate airport in the dispatch release whenever the METAR, Terminal Aerodome Forecast (TAF), or any combination thereof for the destination airport or first alternate airport indicate, by the use of conditional words in the remarks section of such METAR or in one or more time increments of the TAF, that the forecast weather conditions for the destination and the first alternate airport could be less than the authorized weather minimums for those airports. However, the

METAR or TAF must indicate in another time increment that the weather conditions for the destination, first alternate, and second alternate airports are forecast to be not less than the applicable authorized weather minimum values as follows:

a. With respect to the destination airport, the forecast weather conditions must not be less than one-half of the lowest weather minimum visibility value established for the instrument approach procedure expected to be used for an instrument approach at the destination;

b. With respect to the first alternate airport, the forecast weather conditions must not be less than one-half of the alternate weather minimum ceiling and visibility values specified in Omni’s operations specifications for that airport; and

c. With respect to the second alternate airport listed in the dispatch release pursuant to this exemption, the METAR, the appropriate time increment of the TAF, or any combination thereof for that airport must indicate in the main body and remarks section of the METAR or TAF that the forecast weather conditions will be at or above the alternate airport weather minimum ceiling and visibility values specified in Omni’s operations specifications for that airport.

2. No person may dispatch or take off an airplane, when operating under the terms of this exemption, unless the airplane has enough fuel:

a. To fly to the airport to which it is dispatched;

b. Thereafter, to fly to and land at the most distant alternate airport for the airport to which it is dispatched, taking into consideration the anticipated air traffic control routing; and

c. Thereafter, to fly for 45 minutes at normal cruising fuel consumption.3

3. Omni’s pilot in command, while en route, must ensure by way of air-to-ground communication with Omni’s dispatch center and other appropriate facilities, that the pilot is receiving the most current METAR and TAF for the destination airport and the alternate airports. This current weather information must be used when making a decision to proceed to an alternate airport for landing.

4. Before commencing operations in accordance with this exemption, Omni must obtain the approval of the appropriate FAA certificate-holding district office. Omni must ensure that the conditions and limitations listed herein are included in its approved manual(s) for the use and guidance of its flight and ground operations personnel.

5. Each BECMG change indicator in the TAF that is "deteriorating" must be considered valid at the first minute of the becoming period. Each BECMG change indicator in the TAF that is "improving" will not be valid until the last minute of the becoming period of the TAF.

The Effect of Our Decision

Our decision extends the termination date of Exemption No. 10041, to March 31, 2014 unless sooner superseded or rescinded.

Sincerely,

/s/
