More or less paperwork is irrelevant, thats the CAA's job - the fact is that practically (I would imagine, I could be wrong here) the two systems aren't that far apart, and therefore going the extra mile to comply with JAR standards is a worthwhile goal (again, thats just my opinion). While Europeans may feel that their JAR system would be 'cheapened' by an African country being compliant, I think it would open up great oportunities for SA training institutions, as well as opening up a few more opportunities for SA pilots overseas - a very good thing, considering the restrictions facing many of the 'currently disadvantaged' pilots in SA.
Besides, being held to a high standard is never a bad thing in aviation, IMHO. Our CAA still has some work to do though before that would be possible, I would agree!
