## Discrepancy

FOLLOWING INSTALLATION OF A FRESHLY OVERHAULED AUX PUMP INTO THE AIRCRAFT, A FUNCTIONAL AND PRESSURE TEST WAS PERFORMED.  THE PUMP WOULD RUN PUT ONLY PUT OUT 3 PSI. REQUIRED PSI IS 5.  FURTHER TROUBLESHOOTING PERFORMED AND THEN PUMP WOULD ONLY PUT OUT 0.5 PSI.  WHEN THE PUMP WAS REMOVED FOR INSPECTION 2 SCEWS FELL OUT OF THE PUMP INLET FITTING, AND A 1 WAS LOOSE INSIDE.  THE FOURTH SCEW OF THE SET WAS THE ONLY SCEW STILL INSTALLED.  THE PUMP WAS A A8150-B SN 63853.  8130-3 FORM TRACKING NR 15535.  THE PUMP HAD ZERO RUN TIME ON IT, ONLY WAS FUNCTION CHECKED FOLLOWING INSTALLATION AND FOUND THAT IT APPEARED TO HAVE NOT BEEN ASSEMBLED PROPERLY.
