Narrative: The maneuver that was being practiced was stop and go with simulated single engine out to landing. The single engine to landing on Runway 4R was successful to a full stop on centerline. The flaps were raised and throttles were in takeoff position. Only the right engine responded to throttle movements and the left engine had died. At this time; I re-verified that mixtures were rich; propellers to full; boost pumps on. The left fuel selector showed it was in cross-feed position while the right engine was in the main tanks position--main tanks are required for takeoff and landings. My student must have set the left engine fuel selector cross feed as part of a simulated failed left engine during cruise and forgot to set it to main tanks to accomplish the Before Landing Checklist. Thus; the left engine died. As I was restarting the left engine after the third try; the Tower Controller was getting annoyed and told us to taxi off Runway 4R via left turn on Taxiway C and hold short of Runway 4R left. At this airport; there is a third runway; which intersects both 4L and 4R with no intersection sign. My student mistakenly turned onto Runway 29 thinking it was Taxiway C; because C was the next taxi after the intersection. By the time my student reacted to my instructions to stop the airplane; my student was already taxiing on Runway 29. Tower was then really really miffed and told us that we taxied onto an active runway. Tower then redirected us to turn off Runway 4L at Charlie Intersection; which we did. There are not any brake pedals for the right seat; which I was occupying. By this time; I too was speaking sternly to my student to make sure he understood the gravity of what just happened and to emphasize that HE and only HE has the brakes. We called Ground frequency to reposition for takeoff and requested a north departure. We then changed frequency to tower and requested to take off and depart to the north. We took off Runway 4L without further incidents. There were varying factors for this incident--engine dying; student was too distraught to remember about his brakes and misreading of a taxiway. The airport needs to add a runway intersection sign as well as their lines needs to be repainted.


Second narrative: [We] landed during an engine out landing drill. In this case it was the left engine (critical engine) that was allowed to idle. After landing the left engine quit although there was adequate fuel in all tanks; propellers at full RPM; mixtures full [rich]; and the electric boost pumps were on. We reported engine trouble to the Tower and after several attempts; we were able to restart the left engine. The Tower instructed us to Taxi off of Runway 4R to the left via taxiway 'CHARLIE' and hold short of Runway 4L. We ended up taxiing off of Runway 4R onto Runway 29. The Tower then redirected us right turn on Runway 4L then left at 'CHARLIE' off of Runway 4L. Then the Tower directed us to contact Ground. Ground Control got us back into sequence for departure from Runway 4L.


Synopsis: Small aircraft student and instructor pilots had difficulty restarting an engine following a simulated single engine approach and landing JRF airport. When the engine was restarted; the student mistook the crossing runway for the intended taxiway until advised by the instructor and the Tower. The Tower provided new taxi instructions and the aircraft cleared the active runway environment.
