A fail-safe thrust mount (24) to attach a forward engine frame (16) to an aft engine mount (20) upper fitting (40). The thrust mount includes first and second thrust links (30), (32) attached to opposed first and second lateral ends (26), (28) of an evener bar (34), respectively. A center clevis (36

A fail-safe thrust mount (24) to attach a forward engine frame (16) to an aft engine mount (20) upper fitting (40). The thrust mount includes first and second thrust links (30), (32) attached to opposed first and second lateral ends (26), (28) of an evener bar (34), respectively. A center clevis (36) extends forwardly from the forward abutment surface (38) of the upper fitting (40). The center clevis (36) accepts a center portion (42) of the evener bar (34) and secures the evener bar therein using first and second connection mechanisms. The first connection mechanism is located forward of the second connection mechanism with respect to an airplane frame of reference. The first connection mechanism preferably includes a primary pin (44) inserted snugly through the center clevis (36) and through a primary pin hole (58) in the evener bar. The second connection mechanism preferably includes a reduced diameter catcher pin (46) inserted through the center clevis (36) and through a catcher pin hole (60) in the evener bar. The catcher pin connection includes a diametric gap (68) between the catcher pin (46) and the evener bar catcher pin hole (60). The evener bar (34) includes an aft edge (48) positioned near, though not normally contacting, the upper fitting forward surface (38).
