An aircraft landing gear assembly comprising: a lock link comprising a first link pivotally coupled to a second link, the lock link being movable between a locked, generally aligned condition and an unlocked broken condition, a first one of the links (16a, 16b) including a lock link engagement formation that defines a swept volume as the lock link moves between the locked condition and the unlocked broken condition; an electromechanical rotary unlock actuator comprising: a motor unit arranged to rotate a shaft; a crank arm mounted on the shaft to rotate therewith; and an elongate pawl, which includes a pawl engagement formation, the pawl being movably coupled to the crank arm such that rotation of the shaft in a first direction moves the pawl engagement formation into the swept volume of the lock link engagement formation for engagement therewith to change the lock link from the locked condition to the unlocked condition, and rotation of the shaft in the opposite direction moves the pawl engagement formation out of the swept volume of the lock link engagement formation to permit the lock link to assume the locked condition; and a release mechanism operable to permit the lock link to assume the locked condition in the event of a motor jam which inhibits rotation of the shaft in the second direction, wherein the release mechanism comprises an auxiliary actuator arranged to move the pawl engagement formation relative to the crank arm, characterised by the release mechanism being arranged such that the pawl and the auxiliary actuator are independently movable with respect to one another such that normal operation of the pawl does not require passive movement of the auxiliary actuator. a lock link comprising a first link pivotally coupled to a second link, the lock link being movable between a locked, generally aligned condition and an unlocked broken condition, a first one of the links (16a, 16b) including a lock link engagement formation that defines a swept volume as the lock link moves between the locked condition and the unlocked broken condition; an electromechanical rotary unlock actuator comprising: a motor unit arranged to rotate a shaft; a crank arm mounted on the shaft to rotate therewith; and an elongate pawl, which includes a pawl engagement formation, the pawl being movably coupled to the crank arm such that rotation of the shaft in a first direction moves the pawl engagement formation into the swept volume of the lock link engagement formation for engagement therewith to change the lock link from the locked condition to the unlocked condition, and rotation of the shaft in the opposite direction moves the pawl engagement formation out of the swept volume of the lock link engagement formation to permit the lock link to assume the locked condition; and a motor unit arranged to rotate a shaft; a crank arm mounted on the shaft to rotate therewith; and an elongate pawl, which includes a pawl engagement formation, the pawl being movably coupled to the crank arm such that rotation of the shaft in a first direction moves the pawl engagement formation into the swept volume of the lock link engagement formation for engagement therewith to change the lock link from the locked condition to the unlocked condition, and rotation of the shaft in the opposite direction moves the pawl engagement formation out of the swept volume of the lock link engagement formation to permit the lock link to assume the locked condition; and a release mechanism operable to permit the lock link to assume the locked condition in the event of a motor jam which inhibits rotation of the shaft in the second direction, wherein the release mechanism comprises an auxiliary actuator arranged to move the pawl engagement formation relative to the crank arm, characterised by the release mechanism being arranged such that the pawl and the auxiliary actuator are independently movable with respect to one another such that normal operation of the pawl does not require passive movement of the auxiliary actuator.
