Rule brief

Part 91 is an important rule as it forms the basis of general operating and flight rules for the New Zealand aviation environment. The requirements ensure that the safe operation of aircraft is possible with the minimum endangerment to persons and property.

Part 91 applies to all operators of aircraft. Subsequent operating rule Parts, such as Part 121, Part 135, or Part 104, prescribe additions or exceptions to Part 91 requirements. In all cases an operator will require information from Part 91.

The objective is to standardise the rules for all operators of aircraft by establishing rules applicable to –

  • each person operating an aircraft –
  • generally
  • under VFR
  • under IFR
  • in special circumstances such as displays, aerobatics, parachuting, gliding, and towing
  • any aircraft equipment, instrument, and certificate requirements and specifications
  • aircraft maintenance, preventative maintenance, and alteration requirements
