Spoke to a couple of people about this today and they say;
The chief pilot left of his own volition he was not fired, but there was a falling out with the owner over something.
The CAA has pulled the FTO/TRTO but don't know why.
The CAA did pull the AOC because of a lack of a chief pilot but apparently that has been sorted now, with another chief pilot.
The ex chief pilot had another job to go to not instructing, commercial pilot job.
The operation at EGNR apparently is available for a "franchise opportunity" the CFI and the CPL left a while ago and the remaining FI has since left to do an IR. Havn't been for a while so i don't know if its still operational or not.
