I had a guy walk in the FBO, and start asking about reinstating his expired flight instructor certificates. I know that he has to do the practical test again, and he can also do it with a designated examiner who is rated for that. My question is, if he was a CFI/CFII/MEI does he have to do separate reinstatements for every instructor rating? Would a CFII ride count for CFI and CFII. I would appreciate any input.
