Narrative:

Intermittent stick shaker on rotation and during climb. Climbed to 17000 ft. Consulted with company dispatch and maintenance control. In addition to stick shaker problem, aircraft had left roll tendency which required 15 degrees yoke displacement to counter. Elected to return to msp after discussions with company and referring to cockpit operating manuals for guidance. En route back to msp a ctlability check was performed at 7000-9000 ft. Stick shaker activation occurred on configuring at 5 degrees and 2 degrees flaps. No activation at 15 degrees or greater. Roll tendency decreased with speed and was gone with gear extension. Declared emergency, requested equipment. Flew long straight-in normal approach. No adverse indications on final, normal landing. Callback conversation with reporter revealed the following information: this phenomenon started to occur just at rotation according to the reporter. It was caused by a flap section on the B727-200 being misrigged and that in turn sent faulty signals to the stall warning system. The first officer said that the captain assured the rest of the flight crew that the aircraft was flyable and that it felt good. The so discussed the situation with maintenance and they all decided to return to msp for maintenance assistance.
