The prime cause of the accident was that the pilot was prevented from flying en route at 6500 above all the hills on his way to Taree.
If the NAS airspace had been in place he would not have been forced to descend into a mountain.
Having a current bi annual would not have allowed the pilot to remain at 6500’.
The ATSB were dishonest for not mentioning that the airspace had been reversed from E to C without any valid safety study and also failing to mention that the radar direction had not been complied with by AsA.
If the radar direction had been complied with it would have been most likely the aircraft would have remained at 6500’ above the mountains!
Its not called “ road block” airspace for no reason.
