Narrative:

I was giving dual instruction to a student pilot in an small aircraft owned by the student. After doing air work we landed and were taking off again. At approximately 100' AGL the engine died. I told the student 'I've got it', took control and lowered the nose to land straight ahead on the runway. The student, on his own, restarted the engine and applied full power. This carried us further down the runway at altitude and the engine then died again almost immediately. I again told the student 'I've got it' and landed, touching down on the runway but coming to a stop just off the end of the runway. No damage done to the aircraft or anything else. I made 2 mistakes. One of course, was that I failed to verify that the student had visually checked the fuel tanks. He of course had not. (Both fuel gauges read 1/4 at the time the tanks went dry, causing the engine failure.) the second mistake was that I had failed to establish with the student beforehand, that when I say 'I've got it', he is to do nothing unless he is told to. If the engine had run just a few moments longer after he restarted it and applied power, it would have carried us beyond the end of the runway rough terrain might have made this less than 'a good landing'.

Title: GA SMA ENGINE QUIT ON TKOF DUE FUEL EXHAUSTION.

Narrative: I WAS GIVING DUAL INSTRUCTION TO A STUDENT PLT IN AN SMA OWNED BY THE STUDENT. AFTER DOING AIR WORK WE LANDED AND WERE TAKING OFF AGAIN. AT APPROX 100' AGL THE ENGINE DIED. I TOLD THE STUDENT 'I'VE GOT IT', TOOK CONTROL AND LOWERED THE NOSE TO LAND STRAIGHT AHEAD ON THE RWY. THE STUDENT, ON HIS OWN, RESTARTED THE ENGINE AND APPLIED FULL POWER. THIS CARRIED US FURTHER DOWN THE RWY AT ALT AND THE ENGINE THEN DIED AGAIN ALMOST IMMEDIATELY. I AGAIN TOLD THE STUDENT 'I'VE GOT IT' AND LANDED, TOUCHING DOWN ON THE RWY BUT COMING TO A STOP JUST OFF THE END OF THE RWY. NO DAMAGE DONE TO THE ACFT OR ANYTHING ELSE. I MADE 2 MISTAKES. ONE OF COURSE, WAS THAT I FAILED TO VERIFY THAT THE STUDENT HAD VISUALLY CHECKED THE FUEL TANKS. HE OF COURSE HAD NOT. (BOTH FUEL GAUGES READ 1/4 AT THE TIME THE TANKS WENT DRY, CAUSING THE ENGINE FAILURE.) THE SECOND MISTAKE WAS THAT I HAD FAILED TO ESTABLISH WITH THE STUDENT BEFOREHAND, THAT WHEN I SAY 'I'VE GOT IT', HE IS TO DO NOTHING UNLESS HE IS TOLD TO. IF THE ENGINE HAD RUN JUST A FEW MOMENTS LONGER AFTER HE RESTARTED IT AND APPLIED POWER, IT WOULD HAVE CARRIED US BEYOND THE END OF THE RWY ROUGH TERRAIN MIGHT HAVE MADE THIS LESS THAN 'A GOOD LNDG'.
