Tip Rib, Wood Spar

Tip rib, J3/J4 wood spar Note: For Wood Spar J-3's these ribs need to be repositioned on the wing assembly from 178 1/2 to 181 which places the rib at the same position as called out for the Metal Spar J-3. This position change better supports the tip bow assembly which causes less tip bow distortion.
