What was found
CRACKS IN THE UPPER OUTBOARD CORNERS OF THE RUDDER CABLE CUT-OUTS ON THE 0712616-1 BULKHEAD ASSEMBLY. AREA IN WHICH CRACK OCCURS IS RELATIVELY THIN GAUGE MATERIAL THAT APPARENTLY PROVIDES LITTLE STRUCTURAL STRENGTH. THE FLANGES IN THIS AREA DO LITTLE MORE THAN SERVE AS A FASTENING POINT FOR AN AERODYNAMIC FAIRING. IT IS DOUBTFUL IF THIS DEFECT IMPAIRS THE STRUCTURAL STRENGTH OF THE BULKHEAD ASSEMBLY AS THE 0712616-4 STIFFENER THAT ATTACHES TO THE -1 BULKHEAD IS MUCH HEAVIER GAUGE MATERIAL.
