Narrative:

During practice ILS approach to runway 35 at ftg, mr X was the pilot and I was the safety pilot. We smelled burning and after that our radios made loud noise and died. We saw all the instrument lights flash and a lot of smoke from the control panel. We decided immediately to make forced landing in an open field. Mr X landed the plane while I performed emergency checklist. After landing, we turned off the plane and evacuate/evacuationed it. We called flight school for help right away via cell phone. The cause of the problem was alternator sending too much voltage, causing damage to airplane radios.
