Rule brief

The Civil Aviation Authority is tasked with ensuring continuing safety in the New Zealand aviation environment. To this end requirements are placed on aircraft owners and operators to ensure that their aircraft are maintained in an airworthy condition and operated safely.

An airworthy aircraft:

  • Conforms in all respects with its approved or properly modified type design:
  • Is maintained in accordance with the appropriate rules:
  • Is fit for flight.

An integral part of aircraft airworthiness is the compliance with any airworthiness directives. The essential requirement of the airworthiness directive system is that all applicable airworthiness directives be complied with. The purpose of Part 39 is to provide the framework for the issue of these airworthiness directives under the responsibilities of the Director.
