## Discrepancy

DURING PHASE 2 INSPECTION OF TAIL AREA, CRACKING AND STOP-DRILLING NOTICED ON STA 257.6 BULKHEAD AT HORIZONTAL SPARE ATTACH POINTS.  STOP-DRILLING IS NOT AN APPROVED REPAIR PER BEECH SI 990, REV 2 PART II.  A P/N 55-4030-5S REINFORCEMENT KIT NEEDED TO BE INSTALLED.  KIT INSTALLED, AIRCRAFT RETURNED TO SERVICE.  SI 990, WHICH REQUIRES INSPECTION, MODIFICATION, OR REPLACEMENT, SHOULD BE C/W EACH INSPECTION ON THESE BULKHEADS.  REFER TO BEECH SI 990 FOR DETAILS.
