## Discrepancy

FUEL INLET ADAPTOR ASSEMBLY WAS REPLACED ON THE ENGINE.  SUBSEQUENT ENGINE RUN-UP AND LEAK CHECK WAS SATISFACTORY.  HOWEVER, A FUEL LEAK WAS NOTED THE FOLLOWING DAY UNDER THE FUEL FLOW DIVIDER.  INSPECTION DISCLOSED THAT ONE OF THE O-RINGS USED TO INSTALL THE FLOW DIVIDER TO THE ENGINE CASE WAS BROKEN.  A NEW O-RING WAS INSTALLED AND NO FURTHER LEAKAGE WAS NOTED.  NOTE, THE O-RING WAS NOT "PINCHED" DURING INITIAL ASSEMBLY.  THE INLET ADAPTOR ASSEMBLY WAS OVERHAULED BY HERITAGE TURBINES, INC., WO RO-6427-PC12, WHO SUPPLIED THE O-RINGS.
