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.

Abstract
A steering apparatus for an auger in its casing to bore a horizontal hole in earth by utilizing four expandable and retractable wings equally spaced at the head of the casing. The wings are actuated by integrated single action low profile hydraulic cylinders energized by external single action hydraulic cylinders to minimize the diameter of the hole bored due to State building codes. Two embodiments of the wings are shown.
