A flight control surface actuator (122-134) includes a mechanism that enables the actuator translation member (204) to be selectively decoupled from the actuator rotating member. The actuator includes an actuation member (202), a translation member (204), an extension member (206), and a locking member (208). The actuation member (202) is adapted to receive a drive force and is configured, in response to the drive force, to rotate and cause the translation member (204) to translate. The extension member (206) surrounds at least a portion of the translation member (204) and is configured to be selectively coupled to, and decoupled from, the translation member (204). The locking member (208) surrounds at least a portion of the extension tube (206) and is movable between a lock position, in which the locking member (208) couples the ex tension member (206) to the translation member (204), and a release position, in which the locking member (208) decouples the extension member (206) from the translation member (204). |
