After 4 yrs of persistence, in 2013 we finally gave up on our J160 which had done 850TT for 2 engines and loads of grief in between. We were unable to rely on the aircraft, and lost sleep over student flying. We were most unhappy with the manufacturers attitude.
We sold it for a very acceptable price in late 2013. We've ordered a Brumby and take delivery soon.
So, todays crunch was a long time coming!
