Abstract
A method and apparatus for operating a locking system for an actuator device. The apparatus comprises a lock collar and a locking device. The lock collar shares a center axis with a piston having a first number of features that extend from the piston away from a center axis of the piston. The lock collar has a second number of features that extend towards the center axis. The locking device is configured to rotate the lock collar between a lock position in which the second number of features of the lock collar is engaged with the first number of features of the piston and an unlock position in which the second number of features of the lock collar is disengaged from the first number of features of the piston.
