PIC or not ?
 

After a longish medical timeout I am somewhat short of hours to revalidate my rapidly expiring EASA PPL. I am mostly flying in the US on a 61.75. Under FAA regulations PIC towards a rating or renewal may be logged if sole manipulator of the controls and if rated for the aircraft. In fact the Instructor in these circumstances does not even have to have a medical.

Do EASA (or more practically examiners) accept these hours as PIC for the purposes of a revalidation.

Under EASA rules, if the instructor does not have a medical they cannot act as an instructor, so you could only be PIC. If you are flying Dual i.e. the Instructor is ecxercising the privileges of an Instructor Crertificate, then you cannot be PIC and the hours are not acceptable towards your 6 hours PIC. If you don't have the hours, do a Prof Check, the hour with an Instructor will not count either with a FAA CFI.

Then they are a passenger.

And you must be current in accordance with 61.75 and 61.56.

I hope your not paying for your "passenger" umm sorry instructor.
