Analysis

On short final at an airspeed bet 120 and 125 KTS full flaps were lowered for landing. When the flaps reached the full down position, the stall warning horn came on and the stick pusher on the rosemont stall avoidance system activated. The captain disengaged the sas clutch and a normal landing was made. The stall warning remained on until touchdown. A calibration check and bench test of the systems components did not revealed the cause of the malfunction.
