What type of aerodrome certification is required for aircraft with a seating capacity exceeding 30 passengers?

The correct answer reflects the requirements outlined in New Zealand aerodrome certification regulations. Aerodromes that accommodate aircraft with a seating capacity exceeding 30 passengers must hold a Part 139 operators certification. This certification ensures that the aerodrome meets specific safety and operational standards necessary to handle larger passenger aircraft effectively and safely.

Part 139 outlines the requirements for the operation of aerodromes that serve scheduled air services, enhancing safety protocols, maintenance, and operational capabilities. This certification encompasses aspects such as runway condition reporting, facilities for emergency services, and other critical operational parameters that are essential when dealing with larger aircraft and higher passenger volumes.

Other options do not apply in this context; for example, Part 91 relates to private and recreational aviation operations and does not necessitate the same level of infrastructure and safety oversight as Part 139. Part 135 pertains to charter and air transport operations, but does not govern aerodrome certification in the same way. The option implying that no certification is required does not align with the regulatory framework that prioritizes safety for larger passenger aircraft operations.
