A gearbox mounting link (22, 24, 26) between a gas turbine engine structure and a gearbox mounting location comprises two engine attachment brackets (102a, 102b) secured to an engine structure, and attachment plate (104) rotatably attached between the engine attachment brackets, and a secondary retention sleeve and fastener. The attachment plate (104) includes a fusibly separable section (122) configured to attach to the gearbox (12), a static section (120), and a shear necks (126) connecting the static section to the fusibly separable section. The secondary retention sleeve (108) is supported by and secured to the static section. The secondary retention fastener (112) is supported by the secondary retention sleeve (108), and is disposed through an oversized fastener passage through the fusibly separable section (122), thereby loosely retaining the fusibly separable section in at least one of the two degrees of freedom in the event of a load sufficient to break the shear necks (126), separating the fusible separable section (122) from the static section (120).
