NTSB investigators may have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

As the flight approached its destination, it entered an area of convective activity. The first officer contacted the flight attendant and advised her that she should secure the cabin due to possible turbulence. While descending through 4,000 feet, the airplane encountered "moderate or greater chop." During the encounter, the flight attendant was thrown to the floor while attempting to secure the galley. The captain elected to divert the flight to another airport, where it landed uneventfully. The weather recorded at the destination airport, about the time of the accident, included surface winds at 17, gusting to 22 knots, decreasing thunderstorms, scattered cumulonimbus clouds at 4,200 feet, a broken cloud layer at 9,500 feet, and an overcast layer at 11,000 feet.
