From the fingers of Bill MacGregor at CAA NZ via email.
I asked him directly "There is a rumour that we must have 10hrs on the aircraft before the flight test. Is this true?"
His response was "There are no specified hours on type but you do require a type rating on the type used for the test"
Still no word on aircraft under 5,700kgs that we can use. A kingair 90 would be great...
