There is no mandatory solo aerobatics requirement in the EASA Aerobatic Certificate. However, if an ATO wishes to include some such flights (I've no idea how they would intend supervising them....), then they the aircraft have to be suitable.
Some €urotw@t in another MS tried to interpret the EASA AMC as 'requiring' solo aeros - those with more sense told him he was wrong but EASA might now be taking this up. I certainly hope they won't!
