According to the pilot, he "left Franklin County State Airport (FSO) at 16:00. Flew west from FSO to practice aerobatic maneuvers. After fifteen (15) minutes of aerobatic practice [he] flew to Northern Lights airfield with [the] intention to land and observe first flight of recently assembled biplane from the air. Upon observing that the biplane was not out on the airfield ramp, [he] decided to fly west of [the] field for more aerobatic practice. After 10 minutes of aerobatic practice proper altitude diminished, and during inverted flight and while rolling to upright, [the] airplane "dished out", losing altitude and heading. As a result, [the] right wing struck tree tops and separated from [the] airplane. [The] airplane rolled and tumbled, which resulted in the left wing departing as well. [The] airplane then impacted the ground in an inverted position, bounced approximately seventy five (75) feet, impacted the ground also in an inverted position, and rolled against the tree line."
