Not quite. 213 is equipment based and it's a matter of semantics when it comes to the term "inop." Think of unserviceable when it comes to equipment you can't use for any reason, to include required insp. 215 is operations based concerning flight requirements with/without a xspndr. Some aircraft don't have xspndrs installed. If your xspndr breaks in flight is one thing, but if unserviceble from an equipment point of view prior to flight is something entirely different. Once you comply with 213, if applicable, 215 allows you to fly with the "inop" xspndr. It is what it is.BTW 91.213 says to placard "INOP" and refers to equipment that doesn't work, not for equipment that has exceeded the time limit for check
As for a checkride with the 2 year overdue... not recommended.
