A new alternative uplock release assembly is provided. The assembly comprises a pivot pin having a first end and a second end and an internal bore, a release system operatively connected to the first end of the pivot pin, said release system comprising a cylinder and a piston, said piston having a piston head and an elongated member passing longitudinally through said bore, said cylinder having a pressure port through which a pressure source can be fed. The assembly further comprises a hooking member, a torque member rotatably mounted at the second end of the pivot pin, a biasing system operatively connected to the torque member, said biasing system having a bias cylinder and a biasing means located within the bias cylinder. When biasing force is applied to the torque member, an interlocking means to enable the rotatable interconnection between the torque member and the hooking member in a locked and first position, and an engaging means to interconnect the torque member with a link member. When torque is applied to the link member, the torque is transferred, via the engaging means and interlocking means, to the hooking member forcing the hooking member to rotate around the pivot pin. During alternative operation, pressure is fed through the pressure port, the piston counteracts the biasing force, thereby translating the torque member longitudinally over the pivot pin sufficiently to decouple the torque member and the hooking member from the said locked and first position, to an unlocked and second position enabling the hooking member to rotate around the pivot pin.
