Read the full NTSB narrative

The airplane was being vectored for a night instrument approach in visual meteorological conditions when it encountered severe turbulence. There were no other aircraft in the area when the turbulence occurred. The weather radar showed some thunderstorms to the north of the flight, but the ride had been smooth prior to the turbulence event. The airplane's flight data recorder revealed a gradual increase in vertical accelerations during a 15 second period. During the next 15 seconds, there were a series of jolts, with four vertical accelerations measuring approximately 2.0 positive g's, while three registered 0.5 negative g's. Vertical accelerations continued over the next 75 seconds, with eight exceeding 1.5 positive g's, and two registering about 0.0 g. Lateral and longitudinal accelerations were also noted, and corresponded in time with the vertical accelerations.
