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 stri

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 the fourth lower connection location (75d). The second arm (57) of the third link (53) carries loads during a failure of the fourth link (59). The fourth link (59) connects the fifth upper connection location (39e) with the fitch lower connection location (75e). The connections of the links to the upper fitting (31) and engine (11) are formed of pivotable pin and clevis joints, with spherical beatings (63). Under normal operating conditions, the first link (45), the first arm (55) of the third link (53), and the fourth link (59) work together to carry the vertical and horizontal loads of the engine (11). During a failed link operation, the remaining links work together to carry all loads.
