Narrative:

During a student training an engine failure was experienced. The aircraft had been preflted using a written checklist and found to be acceptable for flight. Fuel in left tank was approximately 8 gallons, fuel in the right tank was approximately 4-5 gallons for a total of 12 gallons. This amount was acceptable for the 1 hour flight since full burn is at 6.5 gallons per hour. Prior to takeoff an engine runup was completed using a written checklist. All items checked ok and found within limits for flight. The takeoff from oun was normal and we climbed to an altitude of 3500 MSL. The engine failure occurred while reviewing steep power turns with student. The engine stopped suddenly, as soon as the failure occurred the aircraft's wings were level and restart procedures completed resulting in restarting the engine after which the student and myself elected to return to the airport at oun. Shortly thereafter we experienced a second engine failure. Once again we attempted to restart the aircraft's engine but were unsuccessful. The student and myself continued to attempt to restart until approximately 100-200 ft AGL in altitude. A forced landing was made in a hay field. Damage to aircraft was caused by striking a barbed wire fence. After bringing the aircraft to a complete stop student and instructor exited as soon as possible. An aircraft from another flight school was dispatched upon hearing the engine call to oun. As this aircraft overflew the site, student and instructor waved ok, then walked to farm house and called for help.

Title: ENG FAILURE INFLT. FORCED LNDG OFF ARPT.

Narrative: DURING A STUDENT TRAINING AN ENG FAILURE WAS EXPERIENCED. THE ACFT HAD BEEN PREFLTED USING A WRITTEN CHKLIST AND FOUND TO BE ACCEPTABLE FOR FLT. FUEL IN L TANK WAS APPROX 8 GALLONS, FUEL IN THE R TANK WAS APPROX 4-5 GALLONS FOR A TOTAL OF 12 GALLONS. THIS AMOUNT WAS ACCEPTABLE FOR THE 1 HR FLT SINCE FULL BURN IS AT 6.5 GALLONS PER HR. PRIOR TO TKOF AN ENG RUNUP WAS COMPLETED USING A WRITTEN CHKLIST. ALL ITEMS CHKED OK AND FOUND WITHIN LIMITS FOR FLT. THE TKOF FROM OUN WAS NORMAL AND WE CLBED TO AN ALT OF 3500 MSL. THE ENG FAILURE OCCURRED WHILE REVIEWING STEEP PWR TURNS WITH STUDENT. THE ENG STOPPED SUDDENLY, AS SOON AS THE FAILURE OCCURRED THE ACFT'S WINGS WERE LEVEL AND RESTART PROCS COMPLETED RESULTING IN RESTARTING THE ENG AFTER WHICH THE STUDENT AND MYSELF ELECTED TO RETURN TO THE ARPT AT OUN. SHORTLY THEREAFTER WE EXPERIENCED A SECOND ENG FAILURE. ONCE AGAIN WE ATTEMPTED TO RESTART THE ACFT'S ENG BUT WERE UNSUCCESSFUL. THE STUDENT AND MYSELF CONTINUED TO ATTEMPT TO RESTART UNTIL APPROX 100-200 FT AGL IN ALT. A FORCED LNDG WAS MADE IN A HAY FIELD. DAMAGE TO ACFT WAS CAUSED BY STRIKING A BARBED WIRE FENCE. AFTER BRINGING THE ACFT TO A COMPLETE STOP STUDENT AND INSTRUCTOR EXITED AS SOON AS POSSIBLE. AN ACFT FROM ANOTHER FLT SCHOOL WAS DISPATCHED UPON HEARING THE ENG CALL TO OUN. AS THIS ACFT OVERFLEW THE SITE, STUDENT AND INSTRUCTOR WAVED OK, THEN WALKED TO FARM HOUSE AND CALLED FOR HELP.
