## Probable cause

THE CAPTAIN'S DELAY IN ISSUING INSTRUCTIONS TO THE FLIGHT ATTENDANTS TO TAKE THEIR SEATS, AND HIS POOR CREW COORDINATION.  A FACTOR IN THE ACCIDENT WAS THE TURBULENCE IN CLOUDS.

## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- In flight encounter with weather, descent - normal
  - weather condition - hail
  - weather condition - rain
  - weather condition - turbulence in clouds (contributing factor)
  - instructions,written/verbal - delayed, pilot in command (cause)
  - crew/group coordination - poor, pilot in command (cause)

## Analysis

THE OPERATOR REPORTED THAT THE FLIGHT WAS DESCENDING THROUGH 26,000 FT IN HEAVY RAIN, HAIL AND MODERATE TURBULENCE. THE FLIGHT CREW TURNED ON THE FASTEN SEAT BELT SIGN AND TOLD THE FLIGHT ATTENDANTS TO TAKE THEIR SEATS. BEFORE THE FLIGHT ATTENDANT IN THE AFT GALLEY COULD REACH HER SEAT, SHE WAS UPSET BY TURBULENCE AND BROKE HER ANKLE.
