Flight Purpose
The flight was intended to take a family friend on a night airplane ride to view the lights of a neighboring city.
Takeoff and Conditions
The takeoff was conducted from a soft, wet grass runway. The aircraft was exceeding the maximum allowable gross weight and had a center of gravity behind the aft CG limits.
Events During Flight
According to passenger statements, the aircraft accelerated very slowly during takeoff. When it left the ground, the stall warning horn began to sound. Continuing upslope, the aircraft struck trees and subsequently dropped to the ground.
Conclusion
The accident sequence involved an overweight aircraft with an aft CG taking off from a soft wet grass runway, resulting in slow acceleration, an immediate stall warning, and collision with trees.
