## Discrepancy

ENGINE QUIT DURING TAKEOFF. THE AIRCRAFT WAS SUBSTANTIALLY DAMAGED.  INVESTIGATION REVEALED A SHEARED DRIVE SHAFT FOR THE ENGINE DRIVEN FUEL PUMP (INJECTOR PUMP).  DISASSEMBLY REVEALED FOD (A SMALL PIECE OF WIRE) JAMMED IN THE ROTOR/VANE.  FURTHER INVESTIGATION OF OTHER COMPONENTS OF THE AIRCRAFT FUEL SYSTEM REVEALED THAT THE LOW PRESSURE FUEL PUMP HAD FAILED INTERNALLY AND FRAGMENTS, INCLUDING PIECES OF THE WIRE-LIKE ROTOR PINS, HAD FLOWED TO THE INJECTOR PUMP.  NOTE: THE INJECTOR PUMP HAD RECENTLY BEEN REPAIRED DUE TO FAILURE CAUSED BY DAMAGED VANES/ROTOR. SUBMITTER SURMISES THAT THE LAST INJECTOR FAILURE WAS ALSO DUE TO FOD FROM THE SAME FAILED LOW PRESSURE PUMP.
