(a) Imposition.--There is hereby imposed, effective July 1, 1984, a State tax of 1.1¢ per gallon, or fractional part thereof, on all fuels used or sold and delivered by distributors within this Commonwealth for use as fuel in turbine-propeller jet, turbojet and jet-driven aircraft and aircraft engines. The tax shall be increased by 0.2¢ per gallon, or fractional part thereof, effective January 1, 1985, and by 0.2¢ per gallon, or fractional part thereof, effective July 1, 1985. Distributors shall be liable to the Commonwealth for the collection and payment of the tax imposed by this section. The tax shall be collected by the distributor and shall be paid to the Commonwealth only once with respect to any fuels.

(b) Annual adjustment.--Beginning on January 1, 1986, and each January 1 thereafter, the tax imposed under this section shall be adjusted annually and shall be set for that calendar year. The adjustment shall be based upon the percentage change of the Producer Price Index for Jet Fuel, as determined by the Bureau of Labor Statistics for the United States Department of Labor, for the most recent 12-month period available as of the immediately preceding November 1. For every 10% increase or decrease in the Producer Price Index, as determined by comparing the index for the first month of the 12-month period with the index for the last month of the period, there shall be a 0.1¢ per gallon, or fractional part thereof, increase or decrease in the rate of tax. The rate of tax shall be determined by the Secretary of Revenue, who shall cause such rate to be published as a notice pursuant to 45 Pa.C.S. § 725(a)(3) (relating to additional contents of Pennsylvania Bulletin) in the Pennsylvania Bulletin on or before December 15 of each year. The tax, as adjusted, shall never exceed 2¢ per gallon, or fractional part thereof, nor shall it be less than 1.5¢ per gallon, or fractional part thereof.

(c) Construction of section.--This section shall be construed in conjunction with the act of May 21, 1931 (P.L. 149, No. 105), known as The Liquid Fuels Tax Act,¹ as if jet fuels were liquid fuels as defined in that act, and all of the provisions of that act, except for section 4 thereof to the extent it imposes any tax, shall apply to the collection, administration and enforcement of the tax imposed under this section. Upon the effective date of the tax imposed by this section upon jet fuels, such jet fuels shall not be subject to the tax imposed by the act of January 14, 1952 (1951 P.L.1965, No. 550), known as the Fuel Use Tax Act,² except that dealer-users shall remain liable to report and pay the fuel use tax on any jet fuels used thereafter upon which the tax provided by this section has not been imposed.

(d) Disposition of taxes.--All moneys collected under this section shall be deposited by the State Treasurer in the Aviation Restricted Account.
