" LAPL's rolling validity had run out, I would expect it to be a renewal and not an hour with an instructor."
Er, I don't think so.
That isn't the way the LAPL's rolling recency works.
The licence has no revalidation, no renewal, no examiner involvement at all.
Simply great, but it does help to read the regulation.
FCL.140.A LAPL(A) — Recency requirements
(a) Holders of an LAPL(A) shall only exercise the privileges of their licence when they have completed, in the last 24 months, as pilots of aeroplanes or TMG:
(1) at least 12 hours of flight time as PIC, including 12 take-offs and landings; and
(2) refresher training of at least 1 hour of total flight time with an instructor.
(b) Holders of an LAPL(A) who do not comply with the requirements in (a) shall:
(1) undertake a proficiency check with an examiner before they resume the exercise of the privileges of their licence; or
(2) perform the additional flight time or take-offs and landings, flying dual or solo under the supervision of an instructor, in order to fulfil the requirements in (a).
