The FAA reported a flight attendant received injuries during the severe turbulence encounter.
On May 29th 2013 the NTSB released their final report concluding the probable cause of the accident was:
An inadvertent encounter with unforecast convective turbulence.
The aircraft was enroute at FL370, the ride had been smooth, the fasten seat belt signs were turned off when the aircraft climbed through FL320. The weather radar showed no returns although both crews were operating their weather radars, there had been no pilot reports of turbulence or other weather reports suggesting turbulence activity. The flight data recorder revealed that the aircraft encountered strong and adverse wind fluctuations in all three axes, the vertical component being 80 knots upwards over 10 seconds. Weather radar data revealed after the accident that the aircraft had flown through the extreme top of a rapidly developing area of convective activity, the weather radar showed the cell activity as light to moderate. The NTSB stated, that although both crew were operating their respective weather radars, neither of the pilots actively manipulated the weather radar beam due to lack of severe weather reports, the adjustment of radar beam would have been necessary to detect the cell however.
