I removed my restrictions 1 and 9 about 8 years ago. IIRC, I submitted my exam passes, the fairy bits of CAP 741 and a bunch of worksheets to remove my type restrictions as well. The log book assessor rules have changed recently. You now require approved assessors to sign your experience off. Some guys have also done electrical hand skills courses too. There must be someone who's done this recently as the CAAs goalposts ore on wheels!
