Narrative:

Passing 1000 ft AGL received windshear warning. PF recovered with no loss of altitude or airspeed. PF then commented he was having problems with the controls. I noticed the aircraft trim moving in a nose up direction as PF stated he couldn't trim the elevator nose down. Stabilizer trim was turned off at the flight augmentation control panel to stop the apparent runway trim. Procedures were then followed for a jammed stabilizer (no trim) approach. An emergency was declared, and we returned to the field for an uneventful landing and return to the gate. No assistance was required and there were no injuries. The emergency was declared on departure control -- their handling, and tower's, was extremely professional and helped contribute to an uneventful ending.

Title: FK-100 FLC ENCOUNTERS A RUNAWAY STABILIZER TRIM CONDITION DURING INITIAL CLB.

Narrative: PASSING 1000 FT AGL RECEIVED WINDSHEAR WARNING. PF RECOVERED WITH NO LOSS OF ALT OR AIRSPD. PF THEN COMMENTED HE WAS HAVING PROBS WITH THE CTLS. I NOTICED THE ACFT TRIM MOVING IN A NOSE UP DIRECTION AS PF STATED HE COULDN'T TRIM THE ELEVATOR NOSE DOWN. STABILIZER TRIM WAS TURNED OFF AT THE FLT AUGMENTATION CTL PANEL TO STOP THE APPARENT RWY TRIM. PROCS WERE THEN FOLLOWED FOR A JAMMED STABILIZER (NO TRIM) APCH. AN EMER WAS DECLARED, AND WE RETURNED TO THE FIELD FOR AN UNEVENTFUL LNDG AND RETURN TO THE GATE. NO ASSISTANCE WAS REQUIRED AND THERE WERE NO INJURIES. THE EMER WAS DECLARED ON DEP CTL -- THEIR HANDLING, AND TWR'S, WAS EXTREMELY PROFESSIONAL AND HELPED CONTRIBUTE TO AN UNEVENTFUL ENDING.
