I had a friend ask me about keeping his LAPL current. He's done an hour's flight with an instructor who asked him to hand over his licence and logbook and complete an SRG 1157 form (an examiner form for a skills test or revalidation). He was well inside the 2 yearly timescale so it would not have been a test.
He was told that because the instructor was not an examiner his logbook and form needed to be countersigned by the school examiner.
This sounds like complete BS to me. But are instructors really being told to do this?
