Look at plane3d in core.geom.plane3d
Some of the functions you probably are after, are in this class.

Of course that deals with and infinite plane and an infinite line,
if you are looking for the intersection of a line segment and a
confined plane, you would have to verify if the hypothetical point
of intersection, if it exists, lies within the sets of points of
each object.
You could also look up ray casting methods/algorithms to test if an
infinite line collides with any of the plane's faces. I'm not sure
if any part of Away3D currently implements this, or even if the
methods are made externally accessible if existing.
Hope it helps,
