We study tangent sets of strictly self-affine sets in the plane. If a set in this class satisfies the strong separation condition and projects to a line segment for sufficiently many directions, then for each generic point there exists a rotation O such that all tangent sets at that point are either of the form O((R x C) boolean AND B (0, 1)), where C is a closed porous set, or of the form O((l x {0}) boolean AND B (0, 1)), where l is an interval.
