## Discrepancy

DURING PROPELLER REMOVAL, FOUND CRACKS AT EACH BOLT HOLE.  BULKHEAD WAS INSTALLED WITH NEW A-4227-1 SHOULDER WASHERS AT INITIAL INSTALLATION 498.1 HOURS PRIOR.  SUSPECT CRACKS DUE TO POOR MANUFACTURING.  SUBMITTER SUGGESTS THIS REPAIR STATION HAS REPLACED MANY BULKHEADS WITH CRACKS AT VERY LOW TIMES.
