Im revalidating my SEP this sunday, I have to do a 'skills test' with a PPL/E due to my SEP running out in July 10.
Although I have flown the required 12hrs SEP within the last 12 months 1 of which was with an instructor, but the SEP has lapsed since the last flight, my fault for not getting it signed off earlier.
If your SEP is still current and if you have flown 12 hrs SEP within the last 12 months 1 of which must be with an FI, then a simple sign off.
If not then a flight either with a FI if your SEP is current, if not current a flight with a PPL/E.
