Narrative:
At leveloff FL230 the autoplt trim ran away nose up. Instead of leveling off at FL230, the aircraft quickly pitched and we increased climb. Autoplt was quickly disconnected and aircraft control regained but not before aircraft peaked at FL234. Aircraft recovered to FL230 with no further incident. Aircraft written up at destination. This was a repeat from previous day. Autoplt placard inoperative.
