Okla. Stat. tit. 74, § 74-500.6: Travel by privately owned or chartered airplane -

Reimbursement of fuel costs for personal aircraft used in criminal

pursuits or searches.

A. Travel by any state officer or employee on official state

business on any privately owned or chartered airplane may be

reimbursed in an amount which, when added to per diem and

reimbursement for lodging for that trip, does not exceed the

equivalent of automobile mileage plus per diem and reimbursement for

lodging had a privately owned automobile been used for the trip.

The provisions of Section 500.4 of this title shall apply to

calculation of automobile mileage equivalent in this section.

B. Upon completion of each trip, the pilot of any airplane

owned by this state shall enter into a record book the names of all

passengers on the airplane, date, destination, mileage, duration,

purpose, and expense of the trip. The pilot shall sign each entry

in the record book. Said book may be inspected by the State Auditor

and Inspector.

C. Expenses of the trip are to be charged to the state

departments or agencies of the officers or employees using the

airplane. For the purposes of this section the term expense of the

trip shall include but is not limited to the cost of operating the

airplane, the duration of the trip, and the salary of the pilot.

D. Any non-elected law enforcement official or citizen who

offers for use his or her personal airplane or aircraft for searches

or criminal pursuits may be reimbursed by the public entity

requesting such assistance for the cost of fuel used during such

official business. Each public entity authorizing the use of any

airplane or other aircraft for such purpose shall establish a policy

to verify information they deem necessary to reimburse such

individual for cost of fuel used pursuant to this subsection. Such

information shall be recorded and made available by the public

entity in the same manner as required for other expenditures of

public funds by the public entity.
