A tiltrotor aircraft (10) includes a fuselage (12), a wing member (18) extending from the fuselage, an engine disposed relative to the wing member and a proprotor (26) mechanically coupled to the engine. The proprotor includes a plurality of proprotor blade assemblies (28) each including a spar (40) and a sheath (52) extending spanwise along the spar forming the leading edge (48) of the proprotor blade assembly. The spar has a root section (42), a main section (44) and a tip section (46). The spar has a generally oval cross section at radial stations along the main section and a first edge having a structural bias relative to a generally oppositely disposed second edge at the radial stations along the main section.
