A process of fabricating wing panels for airplane wings having a plurality of elongated wing planks attached together and stiffened with stringers includes assembling the planks on a fixture and holding the planks at a desired curvature, supporting the fixture on an elevator in a pit for adjustment in a generally vertical direction, positioning a stringer against the assembled planks accurately in accordance with a wing design, suspending a downwardly opening yoke over the pit and operating tools mounted an opposite arms of the yoke to fasten the stringer to the assembled planks, moving the support structure longitudinally of the pit along an "X" axis to position the yoke and tools sequentially at fastener positions spaced along the stringer, and moving the elevator in a generally vertical direction to position the assembled planks at a desired elevation corresponding to a next stringer to be attached to the planks. |
