The first six gliders are with a civilian maintenance company as I write and are contracted to be back in service in about twelve weeks.
The motor glider issue is a bit more complicated however it is likely that the fleet will be retrofitted with the Rotax 912 engine.
I would also expect the whole gliding fleet require an Avionic upgrade with 8.33 comms and a traffic system such as FLARM, this is likely to happen to coincide with the EASA 8.33 comms mandate.
