What happened
The pilot reported rotating the aircraft at 65 knots, with liftoff occurring at approximately 70 knots. Shortly after leaving the ground, the aircraft veered to the left and the stall warning horn activated. In response, the pilot lowered the pitch attitude, causing the aircraft to begin settling toward the ground. During this descent, the right main landing gear struck a tree stump.
The investigation
Post-accident calculations determined that the density altitude at the time of the event was 8,200 feet. The weight of the aircraft was calculated to be approximately 383 pounds below its maximum gross weight limit.
