A fail-safe engine mount (19) that includes a first link (45), a second link (47), a third link (53), a fourth link (59), five upper connection locations (39a), (39b), (39c), (39d), (39e) on an upper fitting (31), and five lower connection locations (75a), (75b), (75c), (75d), (75e) on a clevis strip (73) of an engine casing (71) is disclosed. The upper fitting(31) includes structurally reinforced rib elements(35) which intersect to form structural nodes (37). The first link (45) connects the first upper connection location (39a) with the first lower connection location (75a). The second link (47) has a first arm (49) that connects the second upper connection location (39b) with the second lower connection location (75b). The second link (47) carries loads during a failure of either the first link (45) or the third link (53). The second link (47) further includes a second arm (51) for stabilizing the first arm (49). The third link (53) has a first arm (55) that connects the third lower connection location (75c) with the fourth upper connection location (39d). The third link (53) further includes a second arm (57) arranged to connect the fourth upper connection location (39d) with t…
