To sum it up (all rumours of course):
Heli Aviation was a good running ATO in the south of Germany, training on Cabri G2 (composite heli). It was a fast growing (too fast some would say) company with some interesting contracts in Africa and some other countries in the world.
Then Babcock moved in and (after purchasing the company) found out that their new baby wasn’t all that shiny as it looked like when they first bought it. Allegedly they found some discrepancies in technical documentation as well as in all of the other departments.
Rumours say that they had to close down the flight school for a period of time to straighten things out and reported the findings to EASA/LBA.
But maybe it was EASA/LBA who found out themselves as one would imagine that they audited the company due to the change in ownership. Who knows?
But all this took already place in 2016. So A9plus, what took you so long?
