## Discrepancy

DURING ANNUAL INSPECTION, THE SPINNER BULKHEAD WAS FOUND CRACKED AROUND 5 OF THE 6 ATTACHING POINTS.  THIS AREA IS SUPPORTED WITH A DOUBLER.  TWO OF THE 6 ATTACHING POINTS WERE FOUND COMPLETELY BROKEN, AND NO LONGER PROVIDING SUPPORT OF SPINNER.  A REVIEW OF AIRCRAFT RECORDS REVEALED TWO PREVIOUS FALURES OF THIS PART.  FAILED PART REVEALS SEVERAL ELONGATED BOLT HOLES.  SUSPECT CAUSE, IMPROPER TORQUE OF ATTACHING HARDWARE, AND/OR POSSIBLE PROPELLER OR ENGINE VIBRATION.  THE FAILED PART WAS INSTALLED 12-93 WITH 400 HOURS TIS.
