Finishing the Wing Tip

Untitleddrawing-29

The Northstar wing has a very elegant wing tip shape.  Instead of the popsicle stick end found on the Piper wing,  the Northstar wing tapers down and back into a graceful rake. The wing tip extends the leading edge and maximizes the aspect ratio by  increasing the effective wing span, this according to it’s designer. The kit includes a custom shaped fiberglass leading edge element, a tip rib, a wing bow, and a preformed trailing edge sheet metal piece. The fiberglass part is firmly attached with Avex rivets to the end of the leading edge sheet metal and along the top and bottom sides of the wing bow.  The trailing edge metal is preformed and temporarily held in place with strapping tape to keep it positioned for drilling rivet holes.  The holes are then cleco’d down and a stiffener channel that runs diagonally is placed on top for locating rivet holes.  The stiffener channel is then placed inside the trailing edge piece and attached using  flush Avex rivets. Northstar also welded the mount on the wing bow for the attaching the standard Whelen nav/strobes light fixture.  The design of the wing tip is especially appreciated when fabric is attached making the finished tip an extraordinarily beautiful shape.
