Narrative:

I was flying with my student in [a] be-76 for a check ride review flight. We were doing the usual flight training in [the] training area at 6000 feet; and after all maneuvers we started to do single engine operations - single engine failure in air and restart. But after the single engine failure; when we tried to restart the left engine we were unable to restart the left engine using the appropriate methods - using [both with] accumulator and without accumulator methods as per checklist. So we landed [at a nearby airport]. When we were [on the] ground after [the] safe landing we tried to start the left engine and it started after couple of tries.
