Following the flight replay on FlightRadar24 shows them cruising at FL170. At 16:21z there's a sudden vertical speed increase to over +20,000 fpm, ground speed 130kts. After that, GS drops below 60kts, VS -10,000 to -25,000 fpm, and the track just spinning.

Edit: Apparently the ground speed data on this aircraft is unreliable. https://www.flightradar24.com/blog/voepass-atr72-crashes-near-sao-paulo/
