On May 27, 2026, about 1420 eastern daylight time, a special light sport Rainbow Cheetah XLS airplane, N146RC, was substantially damaged when it was involved in an accident near Knightdale, North Carolina. The flight instructor and student pilot were seriously injured. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 instructional flight. The flight instructor reported that he was the pilot in command of the accident flight. He was conducting an introductory flight for a prospective student pilot and planned to demonstrate several maneuvers. The flight departed Cox Airport (NC81), Apex, North Carolina, with 15 gallons of fuel, destined for Raleigh East Airport (W17), Knightdale, North Carolina, for a low approach followed by touch-and-go landings. Upon arrival at W17 the flight instructor entered the airport traffic pattern, turned from the base leg to final approach, and aligned with the runway. He flew the airplane about 3 ft above the runway’s surface and down its entire length before adding power to initiate a climb. As he added power, the engine began to “sputter”, so he reduced power and the engine stabilized and ran normal at a lower rpm setting. He added power again and the engine sputtered, so he reduced the power a second time. Realizing the airplane could not outclimb trees ahead, he turned right towards an open field. He attempted to add power several times; however, each time the engine would sputter. Unable to reach the field, he attempted to fly between a tree and a parked semi-trailer. The airplane struck the trailer and tree, fell about 30 ft and impacted the ground in a nose down attitude. The right wing separated from the fuselage, and the left wing’s leading edge was damaged. The engine was displaced upward due to impact with the ground. The wreckage was retained for further examination.
