## Discrepancy

AFTER INSTALLING ENGINE DRIVEN FUEL PUMP ON THE ENG, MECHANIC WENT OUT TO PERFORM AN ENGINE OPS CHECK AND FOUND ENGINE WOULDN’T KEEP RUNNING UNLESS BOOST PUMP WAS IN THE ON POSITION.  UPON TROUBLESHOOTING MECHANIC FOUND THE SHAFT WAS SHEARED ON THE FUEL PUMP.  NO PROBABLE CAUSE OR RECOMMENDATIONS AT THIS TIME.
