thanks, i'll see if he can argue his case and not have to hand over a further £90 ish
As the rating must of been out of date on ATPL issue, it would only ever of appeared on the back, therefore to get it put back on the front would require the £90 admin fee along with SRG1157.
However, if there is no SEP on the back of the licence, as above they need to do training as required and a skills test rather than a proficiency check, which does complicate things.
Hopefully the CAA will recognise the evidence when it is presented, but it is really for the candidate to list all previously held ratings when they apply for any licence, and to ensure that they are all listed on the back, unless they are willing to see them disappear altogether.
