A friend of mine is working towards his initial CFI. I'm helping him work through regulatory, weather, and other knowledge stuff when time permits. During our most recent ground session he asked me a question that I had never been asked. Here's the setup...
A CFI with a freshly minted MEI (airplane, land) is asked to conduct a flight review for a customer in the customer's own Cessna 421C, a pressurized piston twin certified to >30,000'. This CFI has only flown one type of twin (pick a common training twin, doesn't really matter). He has no time at all in a 421 of any sort or any other twin aside from the trainer in which he trained for his commercial-multi and MEI. Our MEI is otherwise current in all categories and classes for which he is certified, holds a complex endorsement gained during his commercial training, and holds a First Class with no limitations.
The customer is current in all categories and classes for which he is certified, is within the 24mo flight review window, and has a First Class. In short, the customer is fully qualified to be PIC for the flight portion of the flight review.
What's obvious:
The five hour rule does not apply since a flight review is not instruction given for a certificate or rating.
Our MEI cannot act as PIC of the customer's 421C because the MEI is missing a high altitude endorsement and a high performance endorsement even though he is category and class certified for airplane multi land.
A CFI does not need to be PIC, or even hold a medical, in cases where the student/customer is able to act as PIC.
Edit: it's a really bad idea to do fly an aircraft type with which you are not familiar.
The question is this:
Can our fresh MEI give the customer a valid flight review in the customer's 421C?
