 Exemption No. 10683

 Regulatory Docket No. FAA-2012-1019

Mr. Dale M. Ranz

President

Ranz Aviation

1993-NE. 85th Street

Redmond, WA 98053

Dear Mr. Ranz:

This letter is to inform you that we have granted your request for exemption. 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 September 14, 2012, you petitioned the Federal Aviation Administration 

(FAA) on behalf of Ranz Aviation (Ranz) for an exemption from § 91.529(b) of Title 14, 

Code of Federal Regulations (14 CFR) to the extent necessary to allow Ranz Aviation limited 

operations of its flight engineer activity for flight test certification purposes with an annual 

flight engineer proficiency check concurrent 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.

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 Ranz.

The FAA has issued grant of exemption in circumstances similar in all material respects to 

those presented in your petition. In Grant of Exemption No. 8827 (copy enclosed), the FAA 

found that for those flight engineers that have acquired only 20 hours of flight in the B-707 
2

and B-747 in the past year had the means to assure qualifications and methods of training, and 

currency were within acceptable ranges of assuring compatible levels of safety.

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

 they are similar in all material respects to relief previously requested in the enclosed Grant 

of Exemption No. 8827;

 the reasons stated by the FAA for granting the enclosed Grant of Exemption No. 8827 also 

apply to the situation you present; and 

 a grant of exemption is in the public interest.

Our Decision

Under the authority contained in 49 U.S.C. 40113 and 44701, which the FAA Administrator 

has delegated to me, I hereby grant Ranz Aviation, Inc, an exemption from 14 CFR 

§ 91.529(b) to the extent necessary to allow Ranz Aviation limited operations of its flight 

engineer activity for flight test certification purposes with an annual flight engineer 

proficiency check concurrent 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, subject to the conditions and limitations described below.

Conditions and Limitations

1. Ranz Aviation Inc, 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 required 50 hours of flight time as 

flight engineers on the particular type aircraft within the preceding 12 calendar 

months, provided the combined flight time 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. No Ranz flight engineer may act as a required crew member during passenger 

carrying operations while operating under the provisions of this exemption.

3. This exemption is not valid for operations outside of the United States.

This exemption terminates on January 31, 2015, unless sooner superseded or rescinded.

Sincerely,
