OCTANE100, yep, CASA still have the group licences for the ARRIEL series , i've done a Arriel 2 differances and a RR(Allison) 250 C-40/47 differances course but CASA don't require the courses same with the CT7 Series the old -2A in the 214ST and the FADEC -8A in the S-92 all covered in the "Series", will be interesting to see if they seperate the "Makila series "when the EC 225's come in with Makila 2's in them.
