Hi Val. I renewed my SEP this summer as it was nearly 10 years since I last renewed it and it was going to be a serious pain to revalidate in the future if it went over that time. I’m interested in microlights too so made some enquiries. I was told that you can fly a microlight on a JAA/CAA PPL however you will need to get a microlight add-on to your license (probably pass a GFT with associated training to be able to do so and undoubtedly pay the CAA a further fee). The problem with this route is that as well as satisfying the renewal requirements for the micolight add-on you must also satisfy the SEP requirements as well. If you pay more wedge to transfer your license to a NPPL you can then do a micolight test to qualify fo a NPPL(M). This NPPL(M) can be revalidated without the necessity to keep the pure NPPL valid.

This is it as I understand it. If I am incorrect please feel free to correct me.
