## Discrepancy

AIRCRAFT USED AS A TRAINER.  ELEVATOR HINGE (RIB) FOR BOLT HOLE BECAME WORN.  BUSHING AND BEARING BECAME WORN.  BOLT WAS FOUND WORN.  BRACKET BECAME WORN.  BOLT HOLE IN RIB WAS WORN EXCESSIVELY (.25 INCH OR BETTER).   WITH OUTBOARD RIB WORN, THIS PUT MORE SUPPORT ON BRACKET WHICH PUT MORE STRESS ON THE SPAR WHICH CAUSED SPAR TO CRACK.  SUBMITTER RECOMMENDS OPEN ELEVATOR EVERY 1,000 HOURS TO INSPECT SPAR.
