NTSB narrative
The Boeing 737 departed into an area of known thunderstorms. After departure, at an altitude of 15,000 feet, the flight was operating in and out of clouds. The pilot reported that he was not receiving any significant weather radar returns ahead of the airplane. However, as he cleared a layer of clouds, he observed a cumulus cloud that was ahead of the airplane. The cloud was too close to avoid and he flew through the top of the cloud. While in the cloud, the airplane encountered turbulence which threw a flight attendant located in the rear of the airplane into the air, and he subsequently fell and fractured his ankle. The captain had briefed the crew prior to departure, but did not include any specific comments about delaying the start of cabin service until clear of the thunderstorms, nor was he specifically required to. The airline had no written direction for the flight attendants to know when they could leave their seats and begin cabin service.
Probable cause
An inadvertent encounter with convective induced turbulence, which injured a flight attendant. Factors were the failure of the airline to supply direction to the flight crew to indicate when the flight attendants could begin cabin service, and the convective induced turbulence.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: local date, investigation status, coordinates, damage. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2002-02-20.
