Abstract

A connection for a lower attachment for a trimmable horizontal stabilizer actuator (THSA) for connecting the lower attachment to a flight control surface. The attachment includes: a surface bracket for coupling to the flight control surface, the surface bracket mounted about a gimbal of the lower attachment by a bushing disposed between the gimbal and the surface bracket; a failsafe plate fittingly engaged on a first end of the bushing; and a tightening ring mounted on a second end of the bushing opposite the first end and secured to the surface bracket by at least one contact screw, such that the contact screw is operable to urge the bushing against the failsafe plate.
