So can anyone explain the real issue with the spar. Did SA just decide because the RAF were going to throw it around, they would give it a life limited to be safe, or was a problem found along the line.
As for expense of it. I have never flown any SA products and am not familiar with the design detail. But could someone explain the spar detail and why it costs so much to replace, hell I don't even know if we are taling about a wing spar or a ctr carry through ? After all its just a little ally fixed gear single !
