Aircraft Accident/Incident Report
Hawthorne, California 90250
Tuesady, August 13, 1991 12:49 PDT
NTSB Narrative Summary Released at Completion of Accident
THE CFI TURNED OFF THE AIRPLANE'S RIGHT ENGINE FUEL SELECTOR TO SIMULATE AN ENGINE FAILURE DURING THE INITIAL CLIMB-OUT FROM THE AIRPORT. AFTER THE DUAL STUDENT PERFORMED THE ENGINE-OUT EMERG CHECKLIST, WHICH INCLUDED FEATHERING THE RIGHT ENGINE PROPELLER, THE CFI INSTRUCTED THE DUAL STUDENT TO RE-ENTER THE RIGHT TRAFFIC PATTERN. THE AIRPLANE WAS NOT EQUIPPED WITH AN UNFEATHERING PROPELLER SYSTEM. THE DUAL STUDENT OVERSHOT THE FINAL APPROACH COURSE WHEN THE CFI NOTED THAT THE LEFT MAIN LANDING GEAR DOWN LIGHT WAS NOT ILLUMINATED. THE CFI TOOK THE CONTROLS AND EXECUTED A SINGLE ENGINE GO-AROUND. THE AIRPLANE FAILED TO CLIMB AND THE CFI ELECTED TO LAND ON A STREET. THE AIRPLANE COLLLIDED WITH A SIGN AND A PICKUP TRUCK BEFORE COMING TO REST.
NTSB Probable Cause Narrative
OVERCONFIDENCE IN THE AIRPLANE'S ABILITY AND HIS PERSONAL ABILITY BY THE INSTRUCTOR PILOT (CFI), BY INTENTIONALLY SHUTTING OFF FUEL TO AN ENGINE DURING A CRITICAL PART OF FLIGHT. THE AIRCRAFT'S LACK OF SINGLE ENGINE PERFORMANCE WAS A RELATED FACTOR.
