Just to be clear:
It doesn't matter how you got your LAPL!
A LAPL is unique in the UK/EASA system, in that it
does not have a Class Rating to be renewed/revalidated.
The privileges of the licence can only be exercised if the holder has, in the 2 years preceding the proposed flight, completed 12 hours as PiC of aircraft covered by the privileges of the LAPL,
plus 1 hour of training with a Flight Instructor, or CRI.
There is
nothing to sign, and
nothing to' Renew' or 'Revalidate.
If the Licence holder falls outside the PiC element of this 'Rolling Validity' at any time, He has to complete the PiC requirement under the supervision of an ATO/RF(Flying School)
There was originally supposed to be the alternative of passing a Flight Test with an Examiner, but until a cockup in the drafting of the requirements is corrected, this is not possible.
There should not be
anything in the 'Signature Page'.
