Disclosed is an actuator for varying the position of a flight control surface on an aircraft, wherein the actuator comprises a no-back device including a backlash adjuster, which is arranged to select a plurality of different backlash lengths. The backlash adjuster may be a nut which moves relative a housing of the no-back device by rotating the nut. Also disclosed is a method of adjusting the backlash (B) in a flight control surface actuator, by moving the backlash adjuster axially to adjust the backlash (B) to a desired value.

No-back device for flight control surface actuator

The disclosure relates to a device for testing means of detecting the loading of the secondary path of a flight control actuator of the type including a primary path and a secondary path able to take up the effort of the primary path in the event of a breakdown of the latter, wherein a tool is able to press against at least one zone of at least one element of the secondary path, as well as a lever arm which by tilting allows the tool to press against the zone so that it exerts a traction and/or compression force on the secondary path, the lever arm being mounted pivotingly on a support able to be fastened on a structure that is mechanically independent of the secondary path.

Test device for the detection of the recovery effort by a secondary flight ordering actuator, and associated test method

The use of at least one attachment screw () that includes means () for detecting the secondary path loading of a flight-control actuator, or associated with a bush that includes such means, for the attachment of the top coupling of the secondary path of a flight-control actuator.
