What was found
ENGINE DRIVEN FUEL PUMP FAILED AFTER 80.9 HOURS, TOTAL TIME AND 6 WEEKS. THE PILOT NOTED THAT THE ENGINE RAN ROUGH DURING TAXI FOR DEPARTURE BUT CLEARED UP PRIOR TO RUN-UP. AFTER THE FLIGHT THE PUMP WAS TESTED BY PRESSURIZING THE SYSTEM WITH THE BOOST PUMP AND SHOWED SIGNS OF INTERNAL LEAKAGE. THE DIAPHRAGM FAILED ALLOWING FUEL TO LEAK OUT THE DRAIN. ALTHOUGH THIS PUMP IS IDENTIFIED AS HAVING COMPLIED WITH SB 615, IT HAD THE SAME FAILURE MODE AS PUMPS AFFECTED BY THIS SB.
