## Discrepancy

ROLLER RIB AT INBOARD END CRACKED (ASSY P/N 45A21104-642) IN THREE PLACES.  RIB, AND BOTH CLIPS.  CRACKING IS FROM RIB MATERIAL BEING TOO THIN, IMPROPER RIGGING, OR EXCESSIVE WEAR OF HORIZONTAL STABILIZER HINGE POINTS.  SUSPECT RIB MATERIAL IS JUST TOO THIN TO CARRY LOAD FROM ROLLER BRACKET.
