A captain reports that during a preflight inspection his first officer was exiting a raytheon beechjet be-400 aircraft when the bottom step of the aircraft boarding stair broke; causing the first officer to fall onto the ramp.

Narrative:

During the preflight inspection process; as first officer was exiting the aircraft; the bottom step on the aircraft boarding stairs broke causing first officer to fall out of the plane onto the ramp. Luckily he was not hurt; but upon looking at the pieces of the broken stair it was likely that the mounts were partially broken prior to their ultimate failure. Suggest inspecting the airstair assembly on the beechjet be-400 fleet to ensure more are not broken to avoid injury to crew or passengers.
