	the door open handle.  The Pilot decelerated slowly, and vibration
	abated below 60 knots, and ceased below 40 knots. The door was loose,
	but the Crewmember held onto the door.  The Pilot then made the

	There was no Caution Advisory Display warning of a Door Open before
	the door opened. The bottom rear roller assembly came out of the
	bottom door track.
