## Discrepancy

ON THREE OCCASIONS THIS AC HAD FUEL SYSTEM PROBLEMS.  IN FEBRUARY THE ENGINE DIED AT IDLE/LOW POWER OPERATIONS.  THE FUEL PUMP WAS REPLACED AND PROBLEM WENT AWAY (OUR OTHER DA-20C1, N6634DC, HAD THE SAME PROBLEM AND REMEDY).  AT THE END OF APRIL 556DC LOST POWER AND  SAFELY LANDED.  THE ENGINE WOULD NOT RUN ABOVE 1500 RPM.  THE FUEL PUMP WAS CHANGED AGAIN, AND  THE PROBLEM WENT AWAY FOR A FEW DAYS.  THE AC THEN HAD AN EMERGENCY LANDING DUE TO POWER FAILURE.  TECH REP REPLACED THE THROTTLE BODY / METERING UNIT AND THE PROBLEM WENT AWAY.  TECH DECLARED THE ISSUE RESOLVED AND RETURNED AC TO SERVICE.  FEEL THERE MAY STILL BE ISSUES WITH THIS ENGINE/WOOD PROP/FUEL SYS CONFIG. THAT HAVE NOT BEEN DISCOVERED. UNKNOWN.
