Can’t see how they can be accused of fiddling the books. Their spin testing has been found to be unacceptable to CASA for unspecified reasons. They are now in the process of having the testing redone by the German testing company approved by the EASA. The latest model the B23 which has a Max weight of 750 kg has already passed and is now a fully certified aircraft . Unfortunately they have a little issue with the Pandemic happening which is a big problem in Europe generally and particularly in the Czech Republic which is delaying things. I would be very surprised if it doesn’t pass the retest.
