Mr. Adam Dennis Manager, Certification Engineering Viking Air Limited Victoria Interna tional Airport 1959 de Havilland Way Sidney, British Columbia V8L 5V5, Canada

Dear Mr. Dennis :
This letter is to inform you that we have granted your petition to extend Exemption No. 13042. It explains the basis for our decision, describes its effect, and lists the conditions and limitations

.
The Basis for Our Decision By letter dated May 1 9 , 201 6 , Mr. Adam Dennis, Manager, Certification Engineering, Viking Air Limited (VAL), Victoria International Airport, 1959 de Havilland Way, Sidney, British Columbia V8 L 5V5, Canada, petitioned the Federal Aviation Administration (FAA) on behalf of VAL for an extension of exemption number 1 3042 (enclosed), which grants relief from § 23.1549(b) of Title 14, Code of Federal Regulations (14 CFR). The proposed exemption, if granted, would allow VAL to use the color white in lieu of green on the Honeywell Primus Apex (Apex TM ) Electronic Flight Instrument System (EFIS) to depict normal engine operating conditions on Model DHC

- 6 Series 400 airplanes for a li mited time.

In your petition, you indicate that a small number of U.S aircraft are affected by Exemption Nos. 10465, 10465A, 11059 , 13042

, and that VAL is requesting an additional 12 month extension to E xemption No. 1 3042 . This would ensure that aircraft delivered after July 31, 201 7 will be fully compliant with § 23.1549(b) and all in

- service deliveries will be retrofitted within three months from that dat e ( October 31, 201 7 ). Y ou provided evidence that the required software modification has been completed, appears complian t with § 23.1549(b)

, and is in the process of being certified through Transport Canada. Approval of your e xemptionrequest will permit a small number of U.S. deliveries prior to completion and approval of the required changes that make the design co m pliant w ith § 23.1549(b)

. The FAA has determined that good cause exists for waiving the requirement for Federal Register publication because the exemption, if granted, would not set a precedent, and any delay in acting on this petition would be detrimental to VAL. Additionally, this exemption is an extension of the petitioner’s exemption number 1 3042 , which expire s July 31 , 201 6 for new aircraft and October 31, 201 6 for in

- service aircraft.

Having reviewed your reasons for requesting an exemption, I find that

—

• T hey are similar in all material respects to relief previously requested in the enclosed Grant of Exemption Nos. 10465, 10465A

, 11059 , and 130 4 2 ;

• T he reasons stated by the FAA for granting the enclosed Grant of Exemption Nos. 10465, 10465A

, 11059 , and 13042 al so apply to the situation you present; and

• A grant of exemption is in the public interest.

Our Decision The FAA has determined that the justification for the issuance of Exemption No. 13 04 2A remains valid with respect to this exemption and is in the publi c interest. Therefore, u nder the authority provided by 49 U.S.C. 106(f), 40113 and 44701, which the FAA Administrator has delegated to me, I grant your petition, subject to the following conditions and limitations.
