Aircraft Accident/Incident Report
Broomfield, Colorado 80021
Friday, February 8, 2002 11:26 MST
NTSB Narrative Summary Released at Completion of Accident
Air traffic control advised the flight crew of possible severe turbulence as they began the en route descent. The captain said she briefed the flight attendant as to the possibility of turbulence. As the airplane continued its descent, the captain turned on the "Fasten Seatbelt/No Smoking" sign. Shortly thereafter, the airplane encountered "severe turbulence." The flight attendant stated that he was out of his seat when he heard the "Fasten Seatbelt/No Smoking" chime. He returned to his seat, but was unable to fasten his seatbelt before the turbulence encounter and was thrown about. The flight crew heard the flight attendant screaming, but were unable to check him due to more demanding flight duties. Priority handling to the airport was requested, and emergency equipment was asked to stand by. The flight attendant was taken to a local hospital where X-rays revealed he had fractured his ankle bone. The flight attendant said he had no recollection of being briefed about possible turbulence by the flight crew.
NTSB Probable Cause Narrative
the flight attendant's failure to fasten his seatbelt when warned of possible turbulence. A contributing factor was the severe turbulence.
