Rule brief

The purpose of Part 145 is to prescribe the certification requirements for organisations wishing to conduct aircraft maintenance activities in New Zealand and the operating requirements for the continuation of this certification. Part 145 may be obtained for various maintenance activities but in particular Part 145 certification is required for:

  • Air transport aircraft and its components with—
  • greater than 9 passenger seats; or
  • a MCTOW greater than 5700 Kg:
  • Overhaul:
  • Maintenance involving the use of a jig:
  • Maintenance requiring the disturbance of bench tested units:
  • Dismantling main cases of engines and rotorcraft transmissions:
  • Propeller and rotor balancing.

Part 145 recognises the capability of an organisation to perform maintenance and determine the compliance of an aircraft and its components with the airworthiness requirements and provides for the certification of that compliance. To support its activities an organisation is required to provide an exposition that includes evidence of an internal quality assurance system, a maintenance control system, staff information, and its proposed activities.

Part 145 adopts the standard layout for the rule parts relating to the certification of organisations. The layout prescribes specific requirements for the certification (entry standards), operation (continued operations), and safety audit (surveillance) of persons carrying out maintenance activities.
