Part 66 Manual of Standards Amendment Instrument 2020 (No. 3)

15 January 2021

The Part 66 Manual of Standards Amendment Instrument 2020 (No. 3) (the instrument) adds two new aircraft type ratings to the list of aircraft specified under the Part 66 Manual of Standards (the Part 66 MOS) as type rated aircraft.

As well the instrument updates the list of type ratings and rating endorsements in Appendix IX by the addition, variation and substitution of items. The instrument also makes minor or machinery-type amendments to the Part 66 MOS.

CASA has made the Part 66 Manual of Standards Amendment Instrument 2020 (No. 3) without complying with the consultation requirements in regulation 11.280 of CASR, for the following reasons:

  • The addition of each new aircraft type rating is at the request of an aircraft operator or approved maintenance organisation, which has advised CASA of its intention to commence operations, or maintenance, of a relevant new aircraft type in Australia very soon. Accordingly, the operator or organisation has requested the addition of the new aircraft type rating as soon as possible, so as not to delay the operation, or maintenance, of the aircraft type.
  • The amendments in the instrument to add new aircraft type ratings to the list of aircraft specified under the Part 66 MOS as type rated aircraft are covered by a determination made by the Director under paragraph 11.275 (1) (a) of CASR, on the basis that it is necessary to make the amendments as soon as practicable in the interests of aviation safety. Each new aircraft type rating is only relevant to an aircraft operator that intends to operate a relevant new aircraft type in Australia, or aircraft engineers employed by an approved maintenance organisation that intends to carry out maintenance in Australia on a relevant new aircraft type. Accordingly, broader consultation under regulation 11.280 on the amendments is not considered necessary by CASA.
