Narrative:
Prior to takeoff, the pilot owner reminded the private pilot of the high air temperature and density altitude. The private pilot initiated a takeoff from the 5,188-foot long asphalt runway; however, he climbed at an airspeed of 60 to 70 mph, rather than the normal climb speed of 85 to 90 mph. The airplane subsequently settled into a cornfield, and came to rest inverted. Both pilots reported that there were no problems with the airplane or engine. The winds were light and variable at 3 knots. The temperature was 86 F, and the density altitude was about 2,300 feet.

Probable Cause: The pilot's failure to maintain proper airspeed, which resulted in a stall/mush into a corn field. A factor was the high density altitude.
