N227PFPipistrel Italia S R L ALPHA TRAINER · 2019

The pilot reported that the airplane was at 5,000 ft and an engine power setting of 5,000 rpm when he began to pitch and roll to practice a chandelle. At the start of the control inputs for the maneuver, he looked down at his kneeboard and personal electronic device and readjusted its position on his leg and around the control stick. The pilot advised that during this time, he may have released the backpressure on the control stick but continued the turn. While focused on the kneeboard he heard the engine rpm increase, then looked up and realized that the airplane had entered an unusual attitude. During this same time, he became disoriented and tried to correct visually, instead of by reference to the instruments. As such, he inadvertently increased the rate of descent and was unable to determine the airplane’s position as it rapidly gained airspeed. He then heard a “pop” sound and deployed the airplane’s ballistic recovery system (BRS). The BRS system’s parachute deployed successfully, and the airplane came to rest in trees without its left wing. The outboard section of the left wing was subsequently recovered; however, the inboard section was not found. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
