What happened
The flight involved a turning maneuver that progressed into inverted flight conditions. Approximately 1,000 feet above ground level, the airplane entered a right spin. As the aircraft descended toward the terrain, the altitude dropped to about 100 feet above the ground. At this lower altitude, the turns within the spin began to decrease in intensity.
The investigation
Investigation details regarding mechanical examination were not provided in the source material. However, it was noted that both occupants held commercial pilot certificates. The owner of the aircraft, who was seated in the rear seat, possessed an acrobatic endorsement. It could not be determined which of the two pilots was actively flying the airplane at the time the incident occurred.
Findings
The primary factor involved was the progression of a turning maneuver into inverted flight and subsequent spin entry. The presence of an acrobatic endorsement on the rear-seat occupant suggests potential involvement in aerobatic operations, though the specific role of each pilot during the event remained undetermined.
