The invention provides an airplane movable control surface balance test fixture and method, and the fixture comprises a frame assembly, the top of the frame assembly is fixedly provided with a supporting beam through a support structure, and the supporting beam is adjustably and fixedly provided with a suspension joint through a locking end plate. A horizontal state indicating plate is installed on the outer side wall of the suspension connector through a plurality of cantilever rods in a supporting mode, a positioning sleeve is arranged outside the cantilever rods and located between the horizontal state indicating plate and the suspension connector in a sleeved mode, a locking nut is fixed to the end of each cantilever rod, and a suspension positioning plug pin is installed on the suspension connector through a detachable lining. A pointer is fixedly mounted on the horizontal state indicating plate through a pointer positioning block; the device also comprises a counterweight assembly which is used for being installed on a to-be-tested movable rudder. The test fixture is used for a balance test and detection trimming of a movable control surface so as to replace a traditional test process, and has the advantages of being simple in operation, visual in observation, convenient to use, good in working stability, high in working efficiency, high in universality and expansibility and the like.
