I think that what he means is that you have a choice re your R22/R44 type rating; you can sit an oral examination with the CAA or you can attend and pass an approved course. In short you have to have passed an examination which is acceptable to the Authority. I will be back at RHC for my annual visit in Sept. It will be interesting to see how they manage to get through the R22, R44 and R66 in 1 week (5 days) as it was tight just doing the R22 and R44 in 8 days as it was before.
Please note that on my course you get the Lycoming engine as well as the airframe.
I now have Part 147 R66 with the RR300 approval, trying to get a differences course approved now, which will bring the time down from 8 days for the full R66 + engine to 5 days.
Again sorry for not being abe to help before Dec.
