NTSB narrative
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.
Probable cause
An inadvertent encounter with turbulence during descent.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: local date, investigation status, damage. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2001-04-10.
