Exemption No. 10773A Regulatory Docket No. FAA-2013-0295

Mr. Donald S. Robson

Chief Pilot

Bristow U.S. LLC

4605 Industrial Drive New Iberia, LA 70560

Dear Mr. Robson:

This letter is to inform you that we have granted your petition to extend Exemption No. 10773. It explains the basis for our decision, describes its effect, and lists the conditions

and limitations.

The Basis for Our Decision

By letter dated March 5, 2015, you petitioned the Federal Aviation Administration (FAA) on behalf of Bristow U.S. LLC (Bristow) for an extension of Exemption No. 10773. That exemption from § 91.9(a) of Title 14, Code of Federal Regulations (14 CFR) allows Bristow to operate Sikorsky S-92A (S-92A) helicopters with limited exposure to engine failure during takeoff and landing while carrying up to 19 passengers between land-based and offshore facilities or when operating between two offshore facilities, day, night, visual flight rules, and instrument flight rules.

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 of the exemption would not set a precedent, and any delay in acting on this petition would be detrimental to Bristow.2

Our Decision

The FAA has determined that the justification for the issuance of Exemption No. 10773 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 hereby grant Bristow U.S. LLC (Bristow) an exemption from 14 CFR § 91.9(a) to allow Bristow to operate Sikorsky S-92A (S-92A) helicopters with limited exposure to engine failure during takeoff and landing while carrying up to 19 passengers between land-based and offshore facilities or when operating between two offshore facilities, day, night, visual flight rules, and instrument flight rules, subject to the following conditions and limitations.

Conditions and Limitations

1. This exemption is limited to operations conducted in Bristow’s S-92A helicopters.

2. This exemption is limited to operations conducted between land-based airports and offshore heliports, or operations conducted between two offshore heliports.

3. This exemption is not valid for operations in foreign airspace without the prior authorization of the Civil Aviation Authority with jurisdiction over that airspace.

4. Occupants of flights conducted under this exemption must wear personal floatation equipment whenever the aircraft is over water and the aircraft must be equipped with floats, accessible rafts, and a 406 MHz beacon.

5. Bristow must make available and provide access, upon request by the FAA, to its engine reliability historical data for the S- 92As in its fleet in order to provide ongoing surveillance of engine reliability.

6. Computations regarding the determination of the approach and departure profiles must not exceed the ICAO standard of 9 seconds of exposure to engine failure related to Performance Class 2 with limited exposure to engine failure.

7. Operations will not be conducted unless the current aircraft weight, altitude and temperature, as provided in the S-92A Rotorcraft Flight Manual, ensure the ability to climb 150 feet per minute at 1,000 feet above the takeoff surface with one engine inoperative and the remaining engine at maximum continuous one-engine inoperative (OEI) power.

8. Bristow must comply with, in addition to other routine preflight computations, the procedures cited in the S-92A Rotorcraft Flight Manual, Part 2, Section III, Supplemental Performance Data, page III-1-50, contained in the paragraphs titled “Elevated Helideck Takeoff and Landing –Limited Exposure – (At Figure 3-22 WAT)” and the paragraph following titled “Vertical Takeoff – Elevated Helideck.”3

9. Operations under the provisions of this exemption must be flown by two pilot crews that are qualified and current in the operation of the S-92A.

10. Bristow’s approved training program mustinclude provisions for training of appropriate crews on the profiles associated with a Performance Class 2 with limited exposure takeoff and arrival, including performance planning. Bristow must document the conduct and completion of that training for appropriate flight

crewmembers.

11. Proficiency in the use of the profiles de scribed in Condition/Limitation No. 10 must be demonstrated satisfactorily during recurrent evaluations required by §§ 135.293 or

135.299.

12. Bristow must establish parameters for takeoff and arrival at helidecks for its flight data monitoring program and provide ongoing surveillance of those operations.

13. Bristow must advise all S-92A flight crewmembers of the provisions of this exemption, and document that notification.

14. A copy of this exemption must be carried onboard each S-92A utilizing these provisions.

The Effect of Our Decision

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

Sincerely,
