I’ll say this one more time regarding the IPC currency and then you run the gauntlet on your own.
FAR Part 61 says valid instrument rating.
The examiner has testing guidelines and requirements laid out in the FSIMS which defines a valid instrument rating as current.
So it’s a gamble that if you turn up that the examiner is oblivious to that detail and you slide through the cracks.
For the record there have been more than a few E3 pilots sent home to get their IPC current and come back to do their flight test and don’t told not to come back based on not having a current IPC.
So take the risk if you want to.
