## Discrepancy

MECHANIC PERFORMING ROUTINE DAILY INSPECTION NOTICED EXCESSIVE ROTATIONAL PLAY IN THE TAILROTOR PITCH CHANGE SPIDER ASSEMBLY.  THIS COMPONENT IS INTERNALLY SPLINED TO THE TAIL ROTOR OUTPUT SHAFT.  EXCESSIVE WEAR ON THE SPLINES WILL ULTIMATELY RESULT IN THE PITCH CHANGE ASSEMBLY TO SKIP OUT OF ITS PROPER POSITION.
