What happened

The instructor and student pilot had completed one touch-and-go landing and the airplane was in the departure climb, when the pilots were instructed by an air traffic controller to "make right traffic." The airplane entered a right turn, and was observed at a "high angle of attack" just prior to entering a descending 90-degree right bank. The airplane struck a parked trailer and skided across the ground, coming to rest under a row of parked trailers. A post-crash fire ensued. Examination of the airplane and engine revealed no pre-impact mechanical anomalies. The Pilot Operating Handbook (POH) for the airplane listed a stall speed of approximately 65 mph at a bank angle of 20 degrees, and 90 mph at a bank angle of 60 degrees. The POH listed a rotation speed between 60 and 65 mph and a normal climb speed of 95 mph.
