What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Instructor was conducting flight training and had just demonstrated left and right slips. About 10 seconds later, the engine completely stopped operating and the propeller stopped rotating about 5-10 seconds after that.
They were about 700FT AGL and the instructor pitched the aircraft for best glide and activated carb heat and asked the student to check that the magnetos were on both and that the primer was in and locked.
Because the aircraft had no starter system, once the propeller stopped spinning, it was not possible to restart the engine while airborne.
The instructor selected an open area on a frozen lake as his emergency landing site. Upon touchdown, the aircraft slowed and flipped onto its back, causing minor external damage.
