HI HB74

Expands the definition of "aircraft" under general excise tax exemptions to include helicopters in addition to multi-engine jet aircraft used in scheduled commercial service.

Creates a new general excise tax exemption for helicopter servicing and maintenance facilities located outside Hawaii airports where at least 75% of helicopters serviced annually are equipped with quiet technology (shrouded tail rotor or tail rotor removal).

Adds definition of "quiet technology" as design modifications to rotorcraft that reduce sound from engine exhaust, tail rotor, or main rotor using either a shrouded tail rotor or removing the tail rotor.

Makes the exemption temporary, effective July 1, 3000, and repealing on December 31, 2028, with prior statutory language restored upon repeal.

Continues existing exemption for jet aircraft service and maintenance facilities of at least 30,000 square feet including ancillary space such as warehouses and administrative areas.
