So Mike, bearing in mind that the FAA require a valid foreign licence, if the FAA were to write to the CAA to ask them to re-verify your licence, would the CAA confirm it was a valid licence?
Because that is what would happen in Englishal's example.
wb9999 As stated earlier my 61.75 is based on a CAA lifetime license which is a UK license not an EASA one.
In which case, sections 72 and 72A of the ANO do apply to you, and are even clearer than part-MED. The "medical certificate forms part of the licence", to quote section 72A. If you're missing a medical certificate then your licence is not complete or rendered valid.
