Part 42 and AC43
PS: If Part 42/145 is applied to Part 135 aircraft, as is currently proposed, that will be another large slab of GA eliminated.
Not quite true non 42 are currently covered under the AWB I mentioned.
RPT aircraft are covered under part 42 as are any charter ops who elect to use part 42 under Subpart 202.181.
When Charter/airwork are forced to go 42/145 they will transition from being covered by the AWB to being covered by part 42 para 9.2.1, so no actual change in use of AC43.
Note also that AC43.1A was superseded by AC43.1B and hence CASA does not list 1A. This also aplies to 2A now superseded by 2B.
