 Exemption No. 10377B

 Regulatory Docket No. FAA-2011-0892

Mr. Jeffrey J. Jenkins

Chief Inspector, Part 135

PHI, Inc.

P.O. Box 90808

Lafayette, LA 70509

Dear Mr. Jenkins:

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

Exemption No. 10377. 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 July 15, 2015, you petitioned the Federal Aviation Administration (FAA) on 

behalf of PHI, Inc. (PHI) for an extension to Exemption No. 10377, as amended. That 

exemption from §§ 91.411(b) and 91.413(c) of Title 14, Code of Federal Regulations 

(14 CFR) allows PHI to perform air traffic control (ATC) transponder tests and inspections 

and altimeter system and altimeter reporting equipment tests and inspections for its Part 135

aircraft maintained under a Continuous Airworthiness Maintenance Program (CAMP). The 

exemption also allows PHI to perform similar tests and inspections on its Part 135 aircraft 

maintained under an approved aircraft inspection program (AAIP).

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.

You have requested, however, that PHI be permitted to accomplish the tests and inspections 

allowed by this exemption when operating outside the United States (U.S.). We have 

reviewed the corresponding International Civil Aviation Organization (ICAO) Standards and 

Recommended Practices and have identified no differences with the regulation from which 

we grant this exemption. However, a foreign country still may not allow you to operate in 

that country under this exemption if it so chooses.

Our Decision

The FAA has determined that the justification for the extension and amendment of 

Exemption No. 10377, 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 PHI, Inc. (PHI) an exemption from 

§§ 91.411(b) and 91.413(c) of Title 14, Code of Federal Regulations to allow PHI to perform 

air traffic control (ATC) transponder tests and inspections and altimeter system and altimeter 

reporting equipment tests and inspections for its Part 135 aircraft maintained under a 

Continuous Airworthiness Maintenance Program (CAMP). The exemption also allows PHI to 

perform similar tests and inspections on its Part 135 aircraft maintained under an approved 

aircraft inspection program (AAIP), subject to the following conditions and limitations.

Conditions and Limitations 

1. All ATC transponder tests and inspections and all altimeter reporting equipment 

tests and inspections must be conducted under PHI’s Part 135 CAMP. 

2. All tests and inspections must be recorded in the aircraft’s maintenance log by the 

person performing each inspection and test. This entry must identify the person, 

the date, and this exemption number.

3. An appropriate record of these tests and inspections also must be kept in PHI’s 

maintenance recording system for Part 135.

4. PHI may operate outside the U.S. under this exemption, unless otherwise 

prohibited by a foreign country.

The Effect of Our Decision

Our decision extends the termination date of Exemption No. 10377, as amended, to October 

31, 2017, unless sooner superseded or rescinded.

Sincerely,

/s/

John Barbagallo

Deputy Director, Flight Standards Service
