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

The airplane was certified as an Experimental Light Sport Aircraft (E-LSA) four days before the accident. The accident occurred during the airplane's first flight since manufacture. Several witnesses reported seeing the airplane depart and then commence a series of left turns about two miles southeast of the airport. While the airplane was established in a left turn it rolled to the left and entered a near vertical descent. The airplane exploded upon impact and a ground fire ensued. The wreckage was found in a vacant field with no obstructions in the general area of the accident site. The absence of any discernible lateral ground markings was consistent with a near vertical impact. Examination of the recovered wreckage revealed no evidence of a pre-impact mechanical malfunction. The pilot did not have any flight experience in a model 601 XL airplane before the accident flight. The pilot's most current flight review was completed more than 16 years before the accident. According to the pilot's wife, it had been nearly 10 years since he last piloted an aircraft.
