## Discrepancy

BEARING AND BOLT FAILED IN THE ELEVATOR BELLCRANK P/N 5360801-4.  CENTER BEARING THAT SUPPORTS THIS BELLCRANK FAILED.  BEARING IS P/N MS27640-4.   BOLT P/N AN4-14 WAS SEVERELY WORN AND BROKEN IN TWO.  IF EITHER END OF THE BOLT SLIPPED OUT OF THIS BELLCRANK, THE A/C WOULD HAVE LOST PRIMARY ELEVATOR CONTROL.  THE ELEVATOR TRIM SYSTEM WOULD STILL FUNCTION.
