Carj crew had an EICAS status message 'flap half speed' en route to their destination. When the message would not clear, the crew was asked to ferry the aircraft to somewhere it could be repaired. They then landed at the nearest suitable airport when they were unable to control the pitch forces on the aircraft.

Narrative:
Had a flap half speed status message appear en route to pbi. In pbi the mechanic performed a test on the system which caused multiple flight control system status messages to appear. He tried to clear the status messages without any success. Maintenance control wanted to ferry the aircraft to cvg. The aircraft had one of its dual system operating. While on the phone with my program manager and maintenance control, I was told to keep the stabilizer trim in the green and put the autoplt on to climb to the upper flight levels. Having confidence in my program manager, my first officer and myself agreed. After departure had to use excessive forward pressure to fly the aircraft, climbed to FL370, cruised at .82 mach then slowed to .74 mach. Climbed to FL410 back to FL370 and finally FL310. After trying different altitudes and airspds, decided to talk to dispatch about the problem. After waiting for an answer, I told them it was best to land the aircraft. Dispatch told me to land at mco. Being just west of jax, told ATC that we needed to land at mco. The excessive forward pressure was gone when flaps were selected to 8 degrees. Made a normal landing in mco.

Title: CARJ CREW HAD AN EICAS STATUS MESSAGE 'FLAP HALF SPD' ENRTE TO THEIR DEST. WHEN THE MESSAGE WOULD NOT CLR, THE CREW WAS ASKED TO FERRY THE ACFT TO SOMEWHERE IT COULD BE REPAIRED. THEY THEN LANDED AT THE NEAREST SUITABLE ARPT WHEN THEY WERE UNABLE TO CTL THE PITCH FORCES ON THE ACFT.
Narrative: HAD A FLAP HALF SPD STATUS MESSAGE APPEAR ENRTE TO PBI. IN PBI THE MECH PERFORMED A TEST ON THE SYS WHICH CAUSED MULTIPLE FLT CTL SYS STATUS MESSAGES TO APPEAR. HE TRIED TO CLR THE STATUS MESSAGES WITHOUT ANY SUCCESS. MAINT CTL WANTED TO FERRY THE ACFT TO CVG. THE ACFT HAD ONE OF ITS DUAL SYS OPERATING. WHILE ON THE PHONE WITH MY PROGRAM MGR AND MAINT CTL, I WAS TOLD TO KEEP THE STABILIZER TRIM IN THE GREEN AND PUT THE AUTOPLT ON TO CLB TO THE UPPER FLT LEVELS. HAVING CONFIDENCE IN MY PROGRAM MGR, MY FO AND MYSELF AGREED. AFTER DEP HAD TO USE EXCESSIVE FORWARD PRESSURE TO FLY THE ACFT, CLBED TO FL370, CRUISED AT .82 MACH THEN SLOWED TO .74 MACH. CLBED TO FL410 BACK TO FL370 AND FINALLY FL310. AFTER TRYING DIFFERENT ALTS AND AIRSPDS, DECIDED TO TALK TO DISPATCH ABOUT THE PROB. AFTER WAITING FOR AN ANSWER, I TOLD THEM IT WAS BEST TO LAND THE ACFT. DISPATCH TOLD ME TO LAND AT MCO. BEING JUST W OF JAX, TOLD ATC THAT WE NEEDED TO LAND AT MCO. THE EXCESSIVE FORWARD PRESSURE WAS GONE WHEN FLAPS WERE SELECTED TO 8 DEGS. MADE A NORMAL LNDG IN MCO.
