The main reason I operate with a PIFR and not MECIR is this: our aircraft is unique in Australia, and it is very difficult and expensive organising a test from one of the two people in the country qualified to test me, one in Darwin and one in Melbourne. Going through the CASA-induced debacle every 2 years is bad enough without doing it every year.
Why does CASA ignore the screaming need for more ATOs?
The PIFR allows me to do everything that the MECIR does, for our purposes.
