Narrative:

Cleared for takeoff on runway 27 at cid. Started takeoff roll. At 80 KTS the nose wanted to come off the ground. By 100 KTS it took excessive forward pressure on the yoke, so I started to trim the stabilizer nose down. Since the plane was loaded to its aft center of gravity limit, as soon as I started to trim, the takeoff warning horn sounded and the captain aborted. The abort was smooth and successful but as we turned off the runway. The plane bogged down. The right inboard main brake froze up and the plane was stuck on the taxiway for 1 hour. No other damage occurred. Supplemental information from acn 267722: center of gravity should be loaded more in the mid range to avoid trim movement on the takeoff roll.

Title: LOSS OF ACFT CTL ON TKOF PROC. TKOF ABORTED.

Narrative: CLRED FOR TKOF ON RWY 27 AT CID. STARTED TKOF ROLL. AT 80 KTS THE NOSE WANTED TO COME OFF THE GND. BY 100 KTS IT TOOK EXCESSIVE FORWARD PRESSURE ON THE YOKE, SO I STARTED TO TRIM THE STABILIZER NOSE DOWN. SINCE THE PLANE WAS LOADED TO ITS AFT CTR OF GRAVITY LIMIT, AS SOON AS I STARTED TO TRIM, THE TKOF WARNING HORN SOUNDED AND THE CAPT ABORTED. THE ABORT WAS SMOOTH AND SUCCESSFUL BUT AS WE TURNED OFF THE RWY. THE PLANE BOGGED DOWN. THE R INBOARD MAIN BRAKE FROZE UP AND THE PLANE WAS STUCK ON THE TXWY FOR 1 HR. NO OTHER DAMAGE OCCURRED. SUPPLEMENTAL INFO FROM ACN 267722: CTR OF GRAVITY SHOULD BE LOADED MORE IN THE MID RANGE TO AVOID TRIM MOVEMENT ON THE TKOF ROLL.
