Embraer EMB-145LR N931AE accident near Kansas City, Missouri

Probable cause

An in-flight encounter with convectively induced turbulence associated with developing thunderstorms under the flight path during the airplane's climb to cruise flight.

NTSB analysis

During climb to cruise flight, the flight attendant was returning to her jumpseat when the airplane encountered convectively induced turbulence associated with developing thunderstorms under the flight path. The flight attendant lost her footing and hit her head on the service galley door. While trying to find something to grab, the flight attendant fell again and injured her wrist and knee. She advised the flight crew that she would be unable to complete her duties and the flight was diverted to seek medical attention for the flight attendant. The operator subsequently confirmed that the flight attendant was seriously injured when her wrist and hand sustained fractures. The flight’s flight data recorder data showed that an upset event occurred during climb; the vertical acceleration ranged from 1.54g to 0.60g in a 1-second period.
