A latch pin actuator (34) for use in connection with an aircraft (10) having folding wings or wing tips (12). The actuator (34) includes housing (38) mountable to a wing portion (12, 16). A latch pin (21) in the form of a hydraulic cylinder is slidably mounted within the housing (38) and on a piston (44) which is fixed to the housing (38). Variable volume fluid chambers (46, 48) are defined in the cylinder body of the latch pin (21). A primary lock member (58) is movable between locked and unlocked positions such that retraction of the latch pin (21) is ...


For use on an aircraft having folding wing tips, where an end portion of each aircraft wing is hingedly connected to an inboard portion of said wing, in a manner so that said end portion is swingable between a spread position, where it and said inboard portion together form a contiguous airfoil for aircraft flight, and a folded position, for reducing the total wing span of said aircraft when it is on the ground, said wing tip being held in a spread position by at least one latch pin, a latch pin actuator, comprising: a housing mountable to one of said wi...
