Analysis

The pilot stated that during takeoff, when he pushed the control stick forward to raise the tail of the airplane, the airplane went to the left. He tried to correct back to the right but was unsuccessful. In an effort to prevent an accident, he decided to attempt the takeoff and became airborne briefly before the wheels impacted the sugarcane field. The airplane nosed over and sustained substantial damage to the vertical stabilizer and rudder. He stated that he was wearing a helmet and only received minor injuries during the accident. The pilot reported no mechanical malfunctions or anomalies that would have precluded normal operation.
