## Discrepancy

MAINTENANCE DISCOVERED THAT THE TAILCONE CATWALK OVER THE VENTRAL STAIRWAY HAD STRUCTURAL CRACKS IN 3 PLACES. THIS IS CONSIDERED A DEFECT IN THE EMERGENCY ESCAPE SYSTEM AND COULD HAVE AN ADVERSE AFFECT ON THE EVACUATION ROUTE.  THE CATWALK WAS REPAIRED IAW ER/A 525099-14 AND RIGGED TO MEET PUBLISHED SPECIFICATIONS.
