## Discrepancy

UPON INSPECTION, A CRACK WAS FOUND IN THE NLG FITTING AT STA 449 BULKHEAD.  THIS CRACK BEGINS IN A SEAL RETAINER HOLE AT LBL 21, AND EXTENDS APPROXIMATELY 2.0 AFT TO THE 449 BULKHEAD.  THE CRACK IS WELL INTO THE RADIUS OF THE NLG FITTING, BUT IT DOES NOT YET ENTER THE FIRST VERTICAL FASTENER HOLE.
