As an examiner if I am revalidating an SEP by experiencce then I require to see either......a successfel flight test with an appropriate licence endorsement or....
Wouldn't this then be revalidation by Proficiency Check, rather than by experience?
Also, I can't really think of a scenario where a licence holder would do the LPC with one FE, then go to a different examiner for the administrative actions. Surely they'd just get the FE to complete the SRG1119 and ratings page after the test.
