(a) If an aircraft is used for a business purpose of the owner, is taxable by a taxing unit, and is used continually outside this state, whether regularly or irregularly, the appraisal office shall allocate to this state the portion of the fair market value of the aircraft that fairly reflects its use in this state. The appraisal office shall not allocate to this state the portion of the total market value of the aircraft that fairly reflects its use beyond the boundaries of this state.
