At first glance. It would apear not, as the basic LAPL doesn't have any Class or Type Ratings attched to it to be 'Revalidated' or' Renewed'.
A CRI could however, carry out 'Differences Training', as this does not renew/revalidate a rating.
If, however, it is accepted that a LAPL, Is both a licence and, by default, an 'SSEA' Class rating combined, then renewing/revalidating the Licence privileges, would be, by the same logic, renewing/revalidating the 'Rating'.
