How do I know whether I require a type rating to work on certain aircraft?

Updated 1 min read Nick Booth

Type ratings are required for “large” aircraft, or those aircraft designated by CASA as “large”. Certain engine types may also require a ‘type’ approval. A comprehensive list is provided in Appendix IX of the Part 66 MOS (Reference: Part 66 MOS, Pages 122 to 149).

In general, type ratings are require for aircraft which fit into one or more of the following three categories:

  1. Maximum Take-Off Weight (MTOW) over 5700kg
  2. Multi-engine helicopter
  3. Other aircraft which CASA has designated as requiring a type rating

See the FAQ What is the difference in definition between a large and small aircraft?
