Human Factors; Procedure
Stall warning activation on approach. The set up to this scenario came from being high and fast due to being turned in earlier than anticipated on approach. To help slow the aircraft; I had the speed brakes extended and flaps 15 while descending and slowing. We were still high at a point 10 miles from the field. I called for 'Gear and Flaps 20' to help me keep the speed back while increasing descent rate. Problem; I left the speed brakes extended. We slowed quickly and while passing approximately 8 miles out and 3;800 FT received a stick shaker. I stowed the speed brake and advanced the thrust lever. This corrected the problem. We elected to discontinue the approach and requested vectors back around. We were given a descent to 3;000 FT and vectored around for an uneventful approach. At the time of this occurrence the pilot not flying was busy configuring; changing radio frequencies and contacting Tower. I believe this problem happened due to the fact I left the speed brake extended when it was not required. Lesson learned: Keep hand on extended speed brake in order to not forget it is deployed.
While on a high; fast approach the Captain extended the speed brakes; landing gear and set flaps 20 in order to regain the profile then received a Stall Warning when airspeed decayed rapidly because of the extended speed brakes.
