## Probable cause

THE IN FLIGHT ENCOUNTER WITH TURBULENCE, AND THE FAILURE OF THE PASSENGERS TO COMPLY WITH INSTRUCTIONS TO RETURN TO THEIR SEATS AND UTILIZE THEIR SEATBELTS.

## Sequence of events

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

- In flight encounter with weather, cruise - normal
  - weather condition - turbulence (cause)
  - instructions,written/verbal - disregarded, passenger

## Analysis

THE AIRLINER ENCOUNTERED IN-FLIGHT TURBULENCE ASSOCIATED WITH DEVELOPING CONVECTIVE CONDITIONS.  THE FLIGHTCREW HAD PREVIOUSLY ILLUMINATED THE SEATBELT SIGN AND THE FLIGHT ATTENDANTS HAD MADE AN ANNOUNCEMENT.  SOME PASSENGERS DID NOT COMPLY WITH THE INSTRUCTIONS AND WERE INJURED.  THE FLIGHT DIVERTED TO ANOTHER AIRPORT AND THE PASSENGERS, WHO ONLY RECEIVED MINOR INJURIES WERE TREATED AND RELEASED FROM A LOCAL HOSPITAL.
