## Discrepancy

DURING AN ANNUAL INSPECTION, FOUND AFT FUSELAGE BULKHEAD CRACKED AT TOP OF CUTOUT FOR ELEVATOR HORN.  50 PERCENT.  THIS IS WHERE THE VERTICAL AND HORIZONTAL STABILIZERS ATTACH.  THIS AREA IS HIDDEN BEHIND THE WEB OF THE VERTICAL STAB AFT SPAR AND WAS FOUND WHEN COMPONENTS WERE REMOVED TO REPAIR FWD SPAR (FOUND CRACKED) OF THE HORIZONTAL STAB.  THE VERTICAL STAB IS NOT OF THE ROUNDED TIP TYPE, HAS AN ALUMINUM FWD ATTACHMENT AND STEEL AFT ATTACHMENT.  (K)
