Incident Overview
Prior to departure, the pilot owner reminded the private pilot of the high air temperature and resulting density altitude. The private pilot then initiated a takeoff from an asphalt runway measuring 5,188 feet in length. Winds were light and variable at 3 knots, the temperature was 86°F, and the density altitude was approximately 2,300 feet.
Climb Performance
During the initial climb, the pilot maintained an airspeed between 60 and 70 mph. This was notably lower than the normal climb speed of 85 to 90 mph for the aircraft. The airplane subsequently settled into an adjacent cornfield and came to rest inverted.
Pilot Reports
Both pilots confirmed that there were no mechanical problems with the airplane or its engine. The flight was conducted under visual conditions with light winds.
Conclusion
The aircraft came to rest inverted in a cornfield following a takeoff where the climb airspeed was below the recommended range. The source does not specify a probable cause.
