Narrative:

My student was coming down to flare about 5 ft above the runway. The airspeed was 76 KTS indicated which is the approach speed. We had full flaps. As he started his flare, the airspeed was slowing down to 67 KTS. I told him to lower the nose and add power. He did not do this, instead he pulled the throttles back to idle. I then said no, tried to add full power for a go around. By that time my student had guarded the throttles and the aircraft came down on all 3 tires. I knew it was a hard landing and that the aircraft was going to have to be looked at. Someone (an FAA inspector) showed us that the propeller was dinged. Also some skin was wrinkled. To prevent this from happening again, I would take over sooner and not let him get out of the instructing parameters. You want the students to go a bit too far so they prevent you from recovering in time.

Title: PLT TRAINEE MADE HARD LNDG IN A SMA TWIN CAUSING THE PROPS 'BLADE CURL' AND SOME SKIN WRINKLE.

Narrative: MY STUDENT WAS COMING DOWN TO FLARE ABOUT 5 FT ABOVE THE RWY. THE AIRSPD WAS 76 KTS INDICATED WHICH IS THE APCH SPD. WE HAD FULL FLAPS. AS HE STARTED HIS FLARE, THE AIRSPD WAS SLOWING DOWN TO 67 KTS. I TOLD HIM TO LOWER THE NOSE AND ADD PWR. HE DID NOT DO THIS, INSTEAD HE PULLED THE THROTTLES BACK TO IDLE. I THEN SAID NO, TRIED TO ADD FULL PWR FOR A GAR. BY THAT TIME MY STUDENT HAD GUARDED THE THROTTLES AND THE ACFT CAME DOWN ON ALL 3 TIRES. I KNEW IT WAS A HARD LNDG AND THAT THE ACFT WAS GOING TO HAVE TO BE LOOKED AT. SOMEONE (AN FAA INSPECTOR) SHOWED US THAT THE PROP WAS DINGED. ALSO SOME SKIN WAS WRINKLED. TO PREVENT THIS FROM HAPPENING AGAIN, I WOULD TAKE OVER SOONER AND NOT LET HIM GET OUT OF THE INSTRUCTING PARAMETERS. YOU WANT THE STUDENTS TO GO A BIT TOO FAR SO THEY PREVENT YOU FROM RECOVERING IN TIME.
