Monday, April 21, 2003 16:10 EDT

NTSB Narrative Summary Released at Completion of Accident

A flight attendant received serious injuries when the domestic scheduled passenger flight encountered turbulence at flight level 290. The flightcrew were diverting around an area of convective activity when moderate turbulence was encountered with a strong updraft. The flight attendant reported that she received a message from another flight attendant to return to her seat and strap in. She was on her way back to the jump seat when the turbulence began. She reported that she "flew through the air" and hit her leg on a galley counter.

NTSB Probable Cause Narrative

The flight into adverse weather encountered by the flight crew, and the flight attendant's restraint not available when she was informed to take her seat. The convective associated turbulence was a contributing factor.
