I am assuming your 5 year multiple entry visa is an M-1 visa (if its a visit visa then skip this post )
You can only enter the U.S on that visa if you are going for flight training from the particular school that issued you the visa ( flight training = Commercial Single , CFI etc )
Since coming for recency in not flight training you are going to need a visit visa (B1/B2) to enter the U.S .
