## Discrepancy

ENGINE FAILED ON FINAL APPROACH.  WAS ABLE TO RESTART AFTER LANDING BUT HAD TO PULL THE MIXTURE CONTROL LEAN ABOUT 1INCH TO KEEP IT RUNNING.  AFTER COOLDOWN, MIXTURE WAS OK AGAIN.  THIS IS THE FIRST OF 3 FUEL PUMP FAILURES ON THIS AIRCRAFT/ENGINE IN APPROX 90 HOURS.  THIS FUEL PUMP WAS INSTALLED ON THE ENGINE AT THE FACTORY WHEN THIS NEW ENGINE WAS BUILT.  NEITHER MFG HAS BEEN ABLE TO DETERMINE THE CAUSE OF ANY OF THE PUMP FAILURES.
