JEAN CLAUDE; A PPL PILOT WITH SEP RATING MAY FLY under LAPL rights, f-e, his medical has expired for PPL right but for LAPS.

If a ATPL Pilot doe not have a SEP rating, he can not fly a SEP plane regardless which rights and medical he will be using.

May be my question was badly asked. Let us be more precise:
I have an ATPL with TR A33 and also CR SEP
For SEP I am using only LAPL privilege (revalidation)
Is it possible? Or do I need another Licence ?

Same with PPL with CR SEP / TMG
As I am using only LAPL privileges may I also use LAPL privilege vor sliding validity ( 1hr flt w FI and 12 hrs within last 24 months) ?

All that independenly from medical which is valid

Yes you can. No other license needed.

Thank you Thomas I hope that the EASA representatives are of the same opinion. In those dramatic days of aviation unemployment that could help to save some flying activity. In some countries (fe Switz) the administrative burden for revalidation or renewal became huge and expensive...
