Abstract
A vane arc segment includes an airfoil and a spar that has a spar platform adjacent a first fairing platform of the airfoil fairing and a spar leg that extends through a hollow airfoil section of the airfoil fairing. An end portion of the spar leg has a spar clevis mount. There is a support platform adjacent the second fairing platform that has first and second through-holes. The spar clevis mount protrudes from the support platform. There is a spar pin that extends through the spar clevis mount and locks the support platform to the spar leg. A baffle extends through the spar platform, through the hollow airfoil section, and through the second through-hole of the support platform. The baffle is secured in a joint to the support platform and thereby limits rotation of the support platform about the spar pin.
