Read the full NTSB narrative

THE ACFT CRASHED ON FINAL APPROACH AFTER THE ENGINE LOST POWER. THE PLT STATED THAT ON FINAL THE ENGINE BACKFIRED, LOST POWER AND WOULD NOT RESPOND TO THROTTLE MOVEMENT. THE ENGINE HAD BEEN THE SUBJECT OF PREVIOUS WRITE-UPS & WORK ORDERS, WHICH INCLUDED FUEL PRESSURE FLUCTUATION, ROUGH ENGINE, BAD FUEL PUMP, ENGINE DIES AT IDLE AND RICH MIXTURE. ON THE DAY OF THE ACCCIDENT THE FUEL INJECTION UNIT WAS REMOVED FOR OVERHAUL AND REPLACED. DURING POST ACCIDENT TESTING THE ENGINE RAN BUT BECAME EXCESSIVELY RICH. MANUAL LEAN GAVE A SIGNIFICANT RISE IN RPM. LATER TESTING OF THE FUEL INJECTION SYSTEM REVEALED THE UNIT OPERATED ERRATICALLY AND WAS RICH AT LOWER PRESSURES.
