1. A vane arc segment comprising:
an airfoil fairing having first and second fairing platforms and a hollow airfoil section extending there between;
a spar having a spar platform adjacent the first fairing platform and a spar leg that extends from the spar platform and through the hollow airfoil section, the spar leg having an end portion that is distal from the spar platform and that protrudes from the second fairing platform, the end portion having a clevis mount, the clevis mount including first and second prongs that have respective pin holes that are coaxially aligned with each other;
a support platform adjacent the second fairing platform, the support platform having a through-hole through which the end portion of the spar leg extends such that the clevis mount protrudes from the support platform; and
a pin disposed in the pin holes and locking the support platform to the spar leg such that the airfoil fairing is trapped between the spar platform and the support platform.
