What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) During an air race, the accident aircraft attempted to pass another aircraft by descending behind, and inside, and appeared to enter wake turbulence generated by the lead aircraft. The accident aircraft appeared to enter the right (upper) wingtip vortex as it rolled left past 90 degrees, corrected back to level, and then entered the left (lower) wingtip vortex, rolling right into a 360 degree barrel roll. With wings almost level, but before arresting the descent, the aircraft impacted the ground.
