The Phantom X1 pilot flew a visual traffic pattern to a grass runway near Three Rivers, Mich., utilized by a combination of light-sport aircraft, powered parachutes, and radio-controlled aircraft.
While on downwind at 400 feet above ground level, he noticed three ground vehicles parked in a lot often used by pilots when they flew radio-controlled aircraft.
As he searched for possible radio-controlled aircraft, he became distracted and allowed his airspeed to decrease, which resulted in an aerodynamic stall.
He was unable to regain control and the plane subsequently hit a line of trees.
The NTSB determined the probable cause as the pilot not maintaining adequate airspeed while flying a visual pattern, which resulted in an aerodynamic stall and subsequent loss of control.
