NTSB narrative

A CESSNA 152 COLLIDED WITH A FENCE DURING A FORCED LANDING. AT 4,000 FT MSL, THE CFI SWITCHED THE FUEL SHUT OFF VALVE TO THE OFF POSITION TO SIMULATE AN ENG FAILURE. THE STUDENT PILOT SWITCHED THE FUEL SHUT OFF VALVE TO THE ON POSITION. THE ENG DID NOT REGAIN RPM. THE CFI THEN 'DOUBLE CHECKED' TO SEE THAT THE STUDENT SWITCHED THE FUEL SHUT OFF VALVE TO THE 'ON' POSITION. THE ENG BEGAN TO FIRE AND THEN QUIT. THE CFI THEN CHECKED THE FUEL SHUT OFF VALVE AGAIN ALONG WITH THE MIXTURE CTRL, MAGNETOS, AND ENG PRIMER. AT 2000 FT MSL THE PROPELLER STOPPED TURNING. THE CFI ENGAGED THE STARTER IN AN ATTEMPT TO RESTART THE ENG. THE CFI OVERSHOT THE INTENDED LANDING AREA AND SELECTED ANOTHER ROAD AND LANDED SHORT OF IT. THE ACFT STRUCK A FENCE AND NOSED OVER. THE ACFT WAS EXAMINED AND THE CARBURETOR FUEL BOWL WAS FOUND EMPTY OF FUEL. AC 61-21 STATES, IN PART, 'THE CFI SHOULD GIVE SIMULATED FORCED LANDINGS BY RETARDING THE THROTTLE.'

Probable cause

IMPROPER PROCEDURE USED BY THE CERTIFIED FLIGHT INSTRUCTOR IN SIMULATING AN ENGINE FAILURE. CONTRIBUTING TO THIS ACCIDENT WAS THE LACK OF TOTAL FLIGHT INSTRUCTION EXPERIENCE OF THE FLIGHT INSTRUCTOR.

  • Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
  • Filled from the NTSB case API where the bulk record had no value: local date, investigation status. Values present in the bulk record are kept.
  • The date is the local date; the NTSB stores the UTC date 1989-04-10.
  • API snapshot SHA-256: c0305f4e5bb09f319c8732a3e96b4995ba0e840462375a6e59f53b5f904fc8d6; retrieved 2026-09-23T07:43:20.820Z.
