## Sequence of events

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

- In flight encounter with weather, cruise
  - weather condition - turbulence in clouds (cause)

## Analysis

During cruise flight at 33,000 feet, the aircraft encountered moderate to severe turbulence. The flight was deviating to the south of course to avoid weather. Upon breaking out of a cloud layer, the captain noted a cumulous cloud ahead that could not be avoided. Upon entering the cloud, they encountered severe turbulence, causing serious injury to 2 flight attendants and minor injuries to 3 passengers. Turbulence had not been forecasted. The seat belt sign had been illuminated for approximately 20 minutes.
