FIELD: aviation.
SUBSTANCE: invention relates to a lower attachment of a flight control actuator, in particular a controlled horizontal stabilizer drive (CHSD), and relates to the adaptation of the elements for use in the auxiliary load transfer path of the lower attachment for the drive. Connection of the lower attachment of the CHSD with the flight control surface contains a surface bracket for connection to the flight control surface, a safety plate, a sealing ring. In this case, the surface bracket is installed near the cardan of the lower attachment through the bushing located between the cardan and the surface bracket. Safety plate is installed at the first end of the sleeve, and the sealing ring is mounted on the second end of the sleeve opposite the first end and is fixed to the surface bracket with a fixing screw so that the fixing screw works to press the sleeve against the safety plate.
EFFECT: increased reliability of the drive, reduced mass of the structure.
