I have just heard that South Africain Instructors are training in the uk. (15 hours Flight training and a test i believe) to be allowed to teach the UK JAR PPL (and more) syllubus in South Africa to british students. They are not completeing any theory or Uk licence conversion or even the FIC course.
What you are referring to is training conducted in accordance with Appendix 1 to JAR-FCL 1.300. It allows non JAR Licence holders to conduct JAA training in an approved FTO outside a JAA Member State. They are having to complete a JAA FI Course but, it may be reduced on the basis of their previous instructional experience. They have to pass a FI Test on completion with a JAA FIE.
