Zusammenfassung:	A method of manufacturing a tiltrotor wing structure (109) including providing a spar mold (402) having a plurality of bores (410) extending from an exterior surface (402e) of the mold (402) to an interior surface (402i) of the mold (402), the plurality of bores (410) corresponding to a plurality of primary coordination holes (422) in a spar member (418), the spar mold (402) having a periphery (406p) defined by a top edge (406t), a bottom edge (406b) and outboard ends (406c, 406d); selecting a plurality of resin impregnated plies (412) to ensure that the plies (412) continuously extend beyond the periphery (406p) of the spar mold (402); laying the plies (412) in the spar mold (402); curing the plies (412) in the mold (402) to form a cured spar member (418) that extends beyond the periphery (406p) of the spar mold (402); and accurately drilling a plurality of primary coordination holes (422) in the cured spar member (418) in the spar mold (402) using a tool (417) positioned in the plurality of bores (410).
