Cessna 172
The flight instructor reported that, during the instructional flight, the student was making a low pass over the snow-covered runway when the airplane encountered a downdraft that decreased the airspeed and increased the descent rate. The instructor reported that he was too relaxed and should have added power at that moment but didn't. The wheels contacted the snow, and the airplane nosed over and came to rest inverted. The airplane sustained substantial damage to the wings. The instructor reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
