Provides sales tax exemption for maintaining, servicing, or repairing of aircraft and sales of machinery or equipment and replacement parts installed on aircraft within aviation district.

This bill exempts certain aircraft maintenance, repair, and equipment sales from New Jersey's sales tax within a designated aviation district. It specifically applies to air carriers operating in the area (including Atlantic City International Airport and the FAA Hughes Technical Center plus a one-mile radius) and covers services like repairs, servicing, and sales of machinery/equipment parts for aircraft. The exemption applies to aircraft with a 6,000-pound or greater takeoff weight and includes both the services and the parts sold for installation. This policy change directly benefits aircraft maintenance businesses and carriers operating in that specific economic zone by reducing their operational costs.
