At plus or minus 60 knots aborted takeoff. Yoke was pushed backwards. Decided to abort, contacted maintenance, taxied back to the gate. Supplemental information from acn 586970: initiated low speed abort due to problems with pitch control.callback conversation with reporter revealed the following information: the crew was flying an EMB135 aircraft. The reporter states they parked the aircraft in cle and were to fly the same aircraft the next morning. After the crew got to the hotel a series of severe thunderstorms, and high wind hit the area all night. On takeoff roll at approximately 60 KTS the control yoke was forced from the captain's hands and went full nose up. At that point the captain aborted the takeoff. After arriving at the gate the pilots found a control tab on the left elevator was hanging almost straight down. It was not in that position when the first officer made the walkaround inspection. The crew had a conference call with air carrier maintenance and flight safety officials. They were told that the manufacturer has added a locking pin to the elevator, when the gust lock is engaged. The locking pin prevents elevator movement in strong winds. This aircraft had not been modified. Maintenance found the control tab bell crank actuator was damaged. Since the aircraft has a T tail, it is not visible from the ground. Had takeoff continued the aircraft would have been uncontrollable nose up. The reporter would like to see all aircraft modified as soon as possible. He also said that the aircraft does not have a powered elevator, he would like to see a control check on takeoff roll to ensure pitch control, similar to that done on DC8 aircraft.

Title: E135 CREW ABORTED TKOF AFTER A PITCH CTL PROB BECAME EVIDENT ON TKOF ROLL.
Narrative: AT PLUS OR MINUS 60 KNOTS ABORTED TKOF. YOKE WAS PUSHED BACKWARDS. DECIDED TO ABORT, CONTACTED MAINT, TAXIED BACK TO THE GATE. SUPPLEMENTAL INFO FROM ACN 586970: INITIATED LOW SPEED ABORT DUE TO PROBS WITH PITCH CTL.CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE CREW WAS FLYING AN EMB135 ACFT. THE RPTR STATES THEY PARKED THE ACFT IN CLE AND WERE TO FLY THE SAME ACFT THE NEXT MORNING. AFTER THE CREW GOT TO THE HOTEL A SERIES OF SEVERE TSTMS, AND HIGH WIND HIT THE AREA ALL NIGHT. ON TKOF ROLL AT APPROX 60 KTS THE CTL YOKE WAS FORCED FROM THE CAPT'S HANDS AND WENT FULL NOSE UP. AT THAT POINT THE CAPT ABORTED THE TKOF. AFTER ARRIVING AT THE GATE THE PLTS FOUND A CTL TAB ON THE L ELEVATOR WAS HANGING ALMOST STRAIGHT DOWN. IT WAS NOT IN THAT POSITION WHEN THE FO MADE THE WALKAROUND INSPECTION. THE CREW HAD A CONFERENCE CALL WITH ACR MAINT AND FLT SAFETY OFFICIALS. THEY WERE TOLD THAT THE MANUFACTURER HAS ADDED A LOCKING PIN TO THE ELEVATOR, WHEN THE GUST LOCK IS ENGAGED. THE LOCKING PIN PREVENTS ELEVATOR MOVEMENT IN STRONG WINDS. THIS ACFT HAD NOT BEEN MODIFIED. MAINT FOUND THE CTL TAB BELL CRANK ACTUATOR WAS DAMAGED. SINCE THE ACFT HAS A T TAIL, IT IS NOT VISIBLE FROM THE GND. HAD TKOF CONTINUED THE ACFT WOULD HAVE BEEN UNCONTROLLABLE NOSE UP. THE RPTR WOULD LIKE TO SEE ALL ACFT MODIFIED AS SOON AS POSSIBLE. HE ALSO SAID THAT THE ACFT DOES NOT HAVE A POWERED ELEVATOR, HE WOULD LIKE TO SEE A CTL CHECK ON TKOF ROLL TO ENSURE PITCH CTL, SIMILAR TO THAT DONE ON DC8 ACFT.
