1. A method of testing a no-back assembly of an actuator, the method comprising:
providing a first actuator connected to a structural member;
providing a second actuator connected to the structural member;
extending the first actuator to a different extent than the second actuator generating stresses in the structural member that impart forces on the first and second actuators;
driving the first actuator while monitoring a drive component of a drive system of the first actuator to determine whether a no-back assembly of the first actuator has isolated the drive system of the first actuator from the forces imparted on the first actuator by the structural member; and
based on monitoring the drive component, determining whether the no-back assembly has failed.
