Folks,
It was a long battle by Sound Air (C208) to get the NZ CAA to change.
Despite the general "FAA" approach in NZ, there is a hard core of Euro/EASAophiles, particularly medical "standards" and the UK CAA hard line resistance to the C208 and similar being used for IFR "commercial" operations.
As it stands in Australia, the additional "airworthiness" requirements imposed on a C208 (ASETPA) are way over the top, and have never been risk management justified, let alone cost/benefit justified.
Tootle pip!!
