Amateur-built JSX-2 accident near Shreveport, Louisiana, May 23, 2021

The NTSB's narrative final · quoted from the NTSB record

Automatic dependent surveillance broadcast track data showed the airplane take off and shortly thereafter maneuver low-level over the lake until track data was lost. A witness reported that he and several others saw the airplane fly across the lake at an altitude of about 200 ft above the water. The witness reported that just before the accident he saw the airplane roll to the right until it was inverted and then it abruptly nosed down and impacted the water in a near vertical attitude. Another witness reported seeing the airplane performing a barrel roll over the lake during the previous week. The airplane's wreckage was recovered and examined. Airframe damage showed that the airplane impacted the water in a near-vertical, nose-low, right-wing-down attitude. Flight control continuity was confirmed, and the engine and engine control unit showed no preaccident malfunctions or failures that could have contributed to the accident. Toxicology testing showed the pilot had used the potentially impairing drugs sertraline, bupropion, quetiapine, gabapentin, and pramipexole. However, is not possible to reliably predict the combined effects of these drugs or how they affected any impairment from underlying medical conditions the pilot had. In addition, the small amount of ethanol detected may have been produced after the pilot’s death.
