An aircraft engine mount includes a mounting platform fixedly joinable to an aircraft pylon, and a cooperating mounting ring fixedly joinable to an aircraft engine. The platform includes a pair of spaced apart lugs defining therebetween a failsafe slot. The mounting ring includes an inner flange fixedly joinable to the engine, and an outer flange extending from the inner flange into the failsafe slot. A pair of side links are pivotally joined to the outer flange and at least one of the lugs to carry loads therebetween. A failsafe pin extends across the failsafe slot and is fixedly joined to the lugs. A clearance hole is provided in the outer flange for receiving the failsafe pin and providing a failsafe alternate loadpath between the mounting ring and platform upon failure of the links to carry loads.
