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 from New Jersey's sales tax the maintenance, servicing, or repair of aircraft (including related machinery, equipment, and replacement parts) when performed within a designated "Aviation District" around Atlantic City International Airport. It directly affects businesses providing these services to qualifying air carriers operating large aircraft (6,000+ pounds takeoff weight) that conduct interstate or international flights. The exemption applies to both labor charges for services and sales of parts/materials used in aircraft maintenance within the defined district. The district includes the airport itself and a one-mile radius around it, aiming to support aviation industry growth in an area historically reliant on tourism and casinos. This is a concrete tax policy change, not a procedural or commemorative measure.
