What happened
The aircraft departed under conditions that compromised its structural and aerodynamic performance. Prior to takeoff, the total weight was approximately 147 pounds over the maximum gross weight limit. Additionally, the forward center of gravity limit was exceeded due to a heavy chemical load weighing 1200 pounds.
During the initial climb phase, at an altitude between 50 and 100 feet above ground level, the aircraft lost flying speed. The loss of airspeed resulted in a stall. Following the stall, the aircraft entered an uncontrolled descent. It impacted the ground approximately 300 yards from the end of the runway, landing in an oat field.
The investigation
Examination of the flight parameters revealed that no effort was made to dump the chemical load before or during the incident sequence. The combination of excessive weight and improper balance directly contributed to the inability to maintain controlled flight.
