1. A steering wing apparatus system for attaching to a pipe casing of an auger digging horizontally comprising:

  • a planar base plate and a hinge means, said base plate having a conical truncated proximate end ending in said hinge means;

    a substantially planar top plate having a shape commensurate to that of the base plate, circular protuberance adjacent said hinge means and connected to said base plate by said hinge means;

    a low profile hydraulic cylinder included under said protuberance and between said top plate and said base plate; and

    a hydraulic hose connected to said low profile hydraulic cylinder;

    whereby the steering wing apparatus can be expanded and contracted via the low profile hydraulic cylinder to direct the horizontal digging of the auger in the pipe casing auger;

    wherein a rectangular plate is attached on a distal end of the top plate for enhancing the amount of expansion capability of the wing apparatus.
