Narrative:
We departed cak at about XA00. The conditions were: temperature 65 degrees F, wind 190 degrees at 3 KTS, runway length 7598 ft by 150 ft (runway 23). All the checklists were properly performed on taxi and before takeoff. Trim, flaps were placed in correct position for takeoff (respectively center of green arc and takeoff mark). The computed speeds were V1=118 KTS and vr=133 KTS. After being cleared by ATC, the captain placed the throttle in position for takeoff power and the plane started rolling. The plane accelerated normally. The copilot voiced takeoff power set, airspeed alive, V1 and vr. At vr, the captain pulled on the control yoke to establish takeoff altitude. Nothing happened. He tried again, still nothing happened, the nose of the plane did not move up. At that time, the captain took the decision to abort initiating full reverse and braking. (The plane's speed was approximately 140 KTS.) with approximately 1000 ft of runway remaining, the captain exercise maximum braking and turned off the runway onto the last taxiway. The plane stopped just beyond the hold short line. At that time we inspected the landing gear and noticed smoke. The captain used the fire extinguisher to start cooling down the brakes, and as a safety precaution he had the copilot call for fire trucks. We also inspected the control yoke by moving it. The first 2 times we moved it, we felt resistance. The third time, everything came back to normal. All flight controls were checked visually and found normal and functioning. Callback conversation with reporter revealed the following information: reporter stated that he observed the captain release the parking brake during the takeoff check and the aircraft accelerated normally. He also acknowledged being present when the flaps and stablizer trim were checked by maintenance and the findings were as follows: when takeoff flaps were selected to 20 units the actual flap setting was 33 units, the stabilizer when set in the takeoff top green range was actually 1 mark nose down. The reporter said he was interviewed by the FAA.

Title: A LEARJET 23 AT 133 KTS REJECTED TKOF DUE TO UNABLE TO ROTATE INCURRING BRAKE AND TIRE DAMAGE. FOUND FLAP INDICATION OR FLAPS OUT OF RIG AND STABILIZER TRIM OUT OF RIG.
Narrative: WE DEPARTED CAK AT ABOUT XA00. THE CONDITIONS WERE: TEMP 65 DEGS F, WIND 190 DEGS AT 3 KTS, RWY LENGTH 7598 FT BY 150 FT (RWY 23). ALL THE CHKLISTS WERE PROPERLY PERFORMED ON TAXI AND BEFORE TKOF. TRIM, FLAPS WERE PLACED IN CORRECT POS FOR TKOF (RESPECTIVELY CTR OF GREEN ARC AND TKOF MARK). THE COMPUTED SPDS WERE V1=118 KTS AND VR=133 KTS. AFTER BEING CLRED BY ATC, THE CAPT PLACED THE THROTTLE IN POS FOR TKOF PWR AND THE PLANE STARTED ROLLING. THE PLANE ACCELERATED NORMALLY. THE COPLT VOICED TKOF PWR SET, AIRSPD ALIVE, V1 AND VR. AT VR, THE CAPT PULLED ON THE CTL YOKE TO ESTABLISH TKOF ALT. NOTHING HAPPENED. HE TRIED AGAIN, STILL NOTHING HAPPENED, THE NOSE OF THE PLANE DID NOT MOVE UP. AT THAT TIME, THE CAPT TOOK THE DECISION TO ABORT INITIATING FULL REVERSE AND BRAKING. (THE PLANE'S SPD WAS APPROX 140 KTS.) WITH APPROX 1000 FT OF RWY REMAINING, THE CAPT EXERCISE MAX BRAKING AND TURNED OFF THE RWY ONTO THE LAST TXWY. THE PLANE STOPPED JUST BEYOND THE HOLD SHORT LINE. AT THAT TIME WE INSPECTED THE LNDG GEAR AND NOTICED SMOKE. THE CAPT USED THE FIRE EXTINGUISHER TO START COOLING DOWN THE BRAKES, AND AS A SAFETY PRECAUTION HE HAD THE COPLT CALL FOR FIRE TRUCKS. WE ALSO INSPECTED THE CTL YOKE BY MOVING IT. THE FIRST 2 TIMES WE MOVED IT, WE FELT RESISTANCE. THE THIRD TIME, EVERYTHING CAME BACK TO NORMAL. ALL FLT CTLS WERE CHKED VISUALLY AND FOUND NORMAL AND FUNCTIONING. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATED THAT HE OBSERVED THE CAPT RELEASE THE PARKING BRAKE DURING THE TKOF CHK AND THE ACFT ACCELERATED NORMALLY. HE ALSO ACKNOWLEDGED BEING PRESENT WHEN THE FLAPS AND STABLIZER TRIM WERE CHKED BY MAINT AND THE FINDINGS WERE AS FOLLOWS: WHEN TKOF FLAPS WERE SELECTED TO 20 UNITS THE ACTUAL FLAP SETTING WAS 33 UNITS, THE STABILIZER WHEN SET IN THE TKOF TOP GREEN RANGE WAS ACTUALLY 1 MARK NOSE DOWN. THE RPTR SAID HE WAS INTERVIEWED BY THE FAA.
