Narrative:

While on a routine training flight approximately 7 mi southwest of west alexandria, oh, I attempted an off airport landing after cabin filled with smoke. Aircraft sustained insubstantial damage in nose-over when nose wheel collapsed in soft earth. Origin of smoke is unknown. Until origin of smoke is determined, no practical solution can be proposed. Callback conversation with reporter revealed the following: the reporter states that to date the source of smoke has not been positively idented, but the aircraft battery and battery cables show some evidence of damage. It is interesting to note that the reporter, who was the instrument, allowed the student to accomplish the emergency landing.
