## Discrepancy

SEVERAL PACKINGS P/N AS3209-010 AND AS3209-012 WERE NOT INSTALLED DURING ASSY OF FUEL MANIFOLDS TO FLOW DIVIDER.  ASSEMBLER SUBSEQUENTLY REALIZED OMITTED ONE OF TWO O-RINGS AT FUEL MANIFOLD LOCATION OF ONE ENG.  ENG TECH MADE RESEARCHES TO TRACK ENG SERIAL NUMBER.  P&WC REQUESTED THAT THE CUSTOMER LANDS HIS A/C TO CHECK ENGINE AND CONFIRM THE MISSING O-RING.  PREVENTIVE ACTION WAS ALSO REQUESTED TO PREVENT ANY FUTURE OCCURRENCE.  ASSEMBLY INSTRUCTION WAS AMENDED TO CLEARLY SHOW WERE THE TWO PARALLEL O-RINGS MUST BE INSTALLED PRIOR TO SLIDING THE FUEL MANIFOLD INTO THE FLOW DIVIDER.  THE INVESTIGATION SHOWED THAT THIS WAS AN ISOLATED CASE.
