Kickdtires,
Kunjani bru and welcome to Proone. I'm sure one of the boffins will give you the gaf but in SA I think it works as follows. If anything has been timex for in excess of 24 months you have to do the whole rickmaroll - exams, flight tests the works. That's on the assumption that your licence has been expired for longer than 24 months and not only certain portions of it, e.g. IF, IR or Comm. I'm sure this does not help you much but I just felt like chirping.
Shala Gashle.
