What about the private checkride? I found some old threads on this
group but I'd call them inconclusive. 61.47 is clear that the examiner
is not (normally) the PIC and is "not subject to the requirements or
limitations for the carriage of passengers that are specified in this
chapter." So how does that interact with 61.51e4? If the student
can't log it, does no-one log the PIC time?

Someone (probably my instructor) told me to log ny checkride as PIC, so
I did - now I'm wondering if I should change it.
