## Analysis

The flight attendant reported that after informing the flight crew that the cabin was secure, she was making her way back to her seat when the flight began to take off. During the takeoff the flight attendant fell and was seriously injured. The flight continued to its destination where the flight attendant was checked by medical personnel. She then elected to return to the airport of origin, and once there was transported to the hospital where it was discovered that her ankle was fractured. Following the accident, the operator modified their procedures to require that the flight deck crew verify that cabin crew are seated prior to taxi.
