During single engine training; my student and I shutdown the right engine for practice. When we attempted to restart; the engine failed to respond. We tried the starter and increasing airspeed. Neither worked. We decided to declare an emergency and land back at base. After receiving vectors and descending; we made a fourth attempt at restarting. This time it worked and the engine seemed to be operating normally. So we canceled the emergency and landed with no further incident.
PA44 instructor pilot reports shutting down the right engine at 5;500 feet for training then being unable to restart it after three tries. An emergency is declared but during descent a fourth attempt to restart is successful and the emergency is canceled.
