Exemption No. 10683A Regulatory Docket No. FAA-2012-1019

Captain Dale M. Ranz

President

Ranz Aviation

1993-NE. 85 th Street Redmond, WA 98053

Dear Captain Ranz:

This letter is to inform you that we ha ve granted your petition to extend and amend Exemption No. 10683. It explains the basis for ou r decision, describes its effects, and lists

the conditions and limitations.

The Basis for Our Decision

By letter dated July 24, 2014, you petitioned the Federal Aviation Administration (FAA) on behalf of Ranz Aviation (Ran z) for an extension of Exemption No. 10683. That exemption from § 91.529(b) of Title 14, Code of Federal Regulations (14 CFR) allows Ranz limited operations of its flight engineer activity for fl ight test certification purposes with an annual flight engineer proficiency check concurre nt with § 61.58 pilot in command (PIC) check required for pilots in lieu of the 50 hours in 6 calendar months or 6 month flight engineer proficiency check requirement.

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 exis ts for not publishing a summary of the petition in the Federal Register because the requested extension would not set a precedent, and any delay in acting on this petition would be detrimental to Ranz.

AFS-14-387-E2
The FAA added condition and limitations #2 to cl arify, per the petitione r’s request, that the checks be done concurrently with the test pilots annual 14 CFR § 61.58 PIC check. This will enhance safety by allowing the flight engineers to train with the pilots as a crew on an annual

basis.

Our Decision

Therefore, under the authority provided by 49 U.S.C. 40113 and 44701, which the FAA Administrator has delegated to me, I hereby grant Ranz Avia tion an exemption from 14 CFR § 91.529(b) to the extent necessary to allow Ranz limited operati ons of its flight engine er activity for flight test certification purposes with an annual flight engineer prof iciency check concurrent with § 61.58 PIC check required for pilots in lieu of the 50 hours in 6 calendar months or 6 month flight engineer profic iency check requirement, s ubject to the conditions and

limitations described below.

Conditions and Limitations

Ranz is granted limited operations to utilize flight engineers on aircraft requiring a flight engineer as a required crew member if they have logged a minimum of 20 hours in lieu of the require d 50 hours of flight time as flight engineers on the particular type ai rcraft within the preceding 12 calendar months, provided the combined flight ti me in any aircraft requiring a flight engineer, or Level B, C, or D simulator that represents any aircraft requiring a flight engineer, is at least 100 hours in the preceding 12 calendar months.

2. The annual flight engineer proficiency check will be done concurrently with the test pilots annual 14 CFR § 61.58 pilot in command (PIC) check 3.
