Any examiner can revalidate a SEP class rating but it would take either a IRE or CRE (single engine)with IRR (Instrument Revalidation Privelages) to revalidate your IR-SP-SE.
So a TRE alone cant revalidate your IR-SP-SE you will have to find a IRE or CRE/IRR
Thats assuming your after a revalidation not a renewal.
I try to keep mine current based on a MP type and the CRE/IRR arent always so easy to locate.
