A helicopter skid having a wall (20) defining an elongated generally cylindrical tubular cross section, and a web (22) extending vertically along the longitudinal axis of the skid between a bottom portion (26) and a top portion (24) of the wall (20). The top and the bottom portions (24, 26) of the wall (20) have a tapering thickness with maxima where the web (22) meets the top and bottom portions (24, 26). The web (22) is preferably formed integrally with the wall (20). A horizontal member (32) formed integrally with the side portions of the wall (20) of the tube extends horizontally through an aperture in the web (22).
