Hi fastbuck,
Been a year since your last reply, I was in a similar situation. A year back I sent application for Type Ratings endorsement to CAA. But was rejected.

Few years back, I got my UK EASA 66 LWTR and succesfully converted to my Hong Kong 66 License.

Did several Type Courses with CX and got my HKAR66 License endorsed. Was trying to endorse the Types into my UK EASA 66, but then just found out CAA did not recognise Hong Kong 147 standard.
Have you got any update in this issue to share....??
or any one else could advise....??
Any feedback/update/info would be much appreciated.
