Narrative:

During taxi out for takeoff at dca and while taxiing in a straight line, I told the first officer to lower the flaps. As we approached 'J' taxiway I began a 90 degree turn to the right toward 'C' taxiway and I couldn't move the nosewheel steering wheel. At that point we were approaching the grass at the edge of 'J' taxiway and I brought the aircraft to a fairly abrupt stop. The flight attendant who was doing her demonstration in the front cabin fell down and injured her tailbone and left elbow. I think that the flaps were not fully down when I tried to turn and since we were taxiing on #1 engine only, insufficient hydraulic pressure was available to the nosewheel steering. From now on, when taxiing on #1 engine only, I will be certain the flaps (aircraft was B727) are fully extended prior to attempting to turn the nosewheel steering wheel.

Title: LGT TAXIING HAS NOSE WHEEL STEERING PROB. ABRUPT STOP INJURES CABIN ATTENDANT.

Narrative: DURING TAXI OUT FOR TKOF AT DCA AND WHILE TAXIING IN A STRAIGHT LINE, I TOLD THE FO TO LOWER THE FLAPS. AS WE APCHED 'J' TXWY I BEGAN A 90 DEG TURN TO THE R TOWARD 'C' TXWY AND I COULDN'T MOVE THE NOSEWHEEL STEERING WHEEL. AT THAT POINT WE WERE APCHING THE GRASS AT THE EDGE OF 'J' TXWY AND I BROUGHT THE ACFT TO A FAIRLY ABRUPT STOP. THE FLT ATTENDANT WHO WAS DOING HER DEMO IN THE FRONT CABIN FELL DOWN AND INJURED HER TAILBONE AND L ELBOW. I THINK THAT THE FLAPS WERE NOT FULLY DOWN WHEN I TRIED TO TURN AND SINCE WE WERE TAXIING ON #1 ENG ONLY, INSUFFICIENT HYD PRESSURE WAS AVAILABLE TO THE NOSEWHEEL STEERING. FROM NOW ON, WHEN TAXIING ON #1 ENG ONLY, I WILL BE CERTAIN THE FLAPS (ACFT WAS B727) ARE FULLY EXTENDED PRIOR TO ATTEMPTING TO TURN THE NOSEWHEEL STEERING WHEEL.
