HI HB74

Amends Hawaii Revised Statutes Section 237-24.9(b) to expand the definition of "aircraft" to include helicopters in addition to jet-powered commercial aircraft.

Establishes a general excise tax exemption for helicopter servicing and maintenance facilities located outside Hawaii airports that service and maintain helicopters equipped with quiet technology on at least 75% of their annual operations.

Defines "quiet technology" as design modifications and technologies that reduce sound from helicopter engine exhaust, tail rotor, or main rotor using shrouded tail rotors or rotor removal.

Creates a temporary tax exemption effective July 1, 3000, with a sunset date of December 31, 2028, after which the statute reverts to its prior form.

Clarifies that the exemption applies to aircraft service and maintenance facilities meeting the 30,000 square foot minimum size requirement and includes related ancillary space for parts, inventory, tools, and administration.
