DRIVE December 6, 2023

A vane arc segment (60) includes an airfoil fairing (62) that has first and second fairing platforms (66, 68) and a hollow airfoil section (64)extending there between. There is a spar (72) having a spar platform (72a) adjacent the first fairing platform (66) and a spar leg (72b) that extends from the spar platform (72a) and through the hollow airfoil section (64). The spar leg (72b) has an end portion (74) with a clevis mount (76) that that protrudes from the second fairing platform (66). A support platform (78) adjacent the second fairing platform (66) has first and second through-holes (80a, 80b). The end portion (74) of the spar leg (72b) extends through the first through-hole (80a) and a pin (82) extends though the clevis mount (76) to lock the support platform (78) to the spar leg (72b). A stabilizer rod (84) extends through the second through-hole (80b) of the support platform (78) and limits rotation of the support platform (78) about the pin (82).
