## Discrepancy

(D-ILHB)  PERFORMED CHECK 5 MAINTENANCE.  DURING THE CUSTOMER'S FLIGHT TEST TO RETURN THE ACFT TO SERVICE, THE ENGINE WAS PURPOSELY SHUTDOWN TO TEST THE RELIGHT CAPABILITY.

DISASSEMBLY REVEALED THE AFT BURNER SEAL WAS BUCKLED AND THE 1ST LPT NOZZLE OUTER/INNER CONE WAS CRACKED, 300 DEGREES IN CIRCUMFERENCE.  BOTH OF THESE PARTS HAVE BEEN SUBMITTED FOR FURTHER INVESTIGATION.
