I think he holds an NPPL with SLMG which he used to gain TMG privileges on an LAPL(S) when applying for an EASA sailplane licence. He now wants an LAPL(A) to add SEP privileges and someone's told him option 2 is available, which of course it isn't. If Paul has logged 21 hours TMG time post LAPL(S) issue then there's no need to convert the NPPL SLMG to EASA, just go straight for the LAPL(A). Just make damn sure that the LAPL(A) you get from the CAA after a successfull skill test has both SEP & TMG privileges on it.
