Aircraft
In open descent; the aircraft pitched over too far resulting in rapid build up of airspeed. About a 5 knot overspeed with bells and alarms. The First Officer recognized the problem but turned off the autopilot too late to prevent the overspeed.
An A320 in Open Descent mode pitched over too aggressively and an approximate five knot overspeed resulted.
