Narrative:

We were doing routine pattern work in preparation for a multieng chkride to be conducted 3 days later. Everything was going smoothly including the use of checklists and excellent lndgs. On the last landing (which was intended to be either the last or next to last landing), we ended up on our belly. How we got there is still up in the air. On landing, I felt something -- I have no idea what it was. I only know I felt something wrong with either the landing gear or the airplane or something. It was a feeling which prompted me to initiate a go around. Since I was instructor and the student was flying, my hand was not on the throttle, his was. By the time my hand hit the throttles, the propellers were hitting the concrete. At that time I elected to ride it out rather than attempt a go around. When I am in the left seat, I am a very conscientious pilot and check the gear usually at least 3 times prior to landing, virtually always at least twice. I am the same way with a fresh student. However, I do occasionally get a little too complacent with a student who is doing well. To some degree, I do suspect that as a possibility that the gear was not extended. However, I know the gear selector was down, and the student swears he had a green light. In addition, the landing gear was partly out of the gear wells when it was jacked up. Preliminary inspection shows no definite gear damage. I feel (or at least hope) that it was gear collapse. Proper rtes have been filed, there were no injuries and only minor damage. FAA has listed it as an incident and has made an on-scene examination.

Title: GA SMA GEAR UP LNDG ON A TRAINING FLT.

Narrative: WE WERE DOING ROUTINE PATTERN WORK IN PREPARATION FOR A MULTIENG CHKRIDE TO BE CONDUCTED 3 DAYS LATER. EVERYTHING WAS GOING SMOOTHLY INCLUDING THE USE OF CHKLISTS AND EXCELLENT LNDGS. ON THE LAST LNDG (WHICH WAS INTENDED TO BE EITHER THE LAST OR NEXT TO LAST LNDG), WE ENDED UP ON OUR BELLY. HOW WE GOT THERE IS STILL UP IN THE AIR. ON LNDG, I FELT SOMETHING -- I HAVE NO IDEA WHAT IT WAS. I ONLY KNOW I FELT SOMETHING WRONG WITH EITHER THE LNDG GEAR OR THE AIRPLANE OR SOMETHING. IT WAS A FEELING WHICH PROMPTED ME TO INITIATE A GAR. SINCE I WAS INSTRUCTOR AND THE STUDENT WAS FLYING, MY HAND WAS NOT ON THE THROTTLE, HIS WAS. BY THE TIME MY HAND HIT THE THROTTLES, THE PROPS WERE HITTING THE CONCRETE. AT THAT TIME I ELECTED TO RIDE IT OUT RATHER THAN ATTEMPT A GAR. WHEN I AM IN THE L SEAT, I AM A VERY CONSCIENTIOUS PLT AND CHK THE GEAR USUALLY AT LEAST 3 TIMES PRIOR TO LNDG, VIRTUALLY ALWAYS AT LEAST TWICE. I AM THE SAME WAY WITH A FRESH STUDENT. HOWEVER, I DO OCCASIONALLY GET A LITTLE TOO COMPLACENT WITH A STUDENT WHO IS DOING WELL. TO SOME DEG, I DO SUSPECT THAT AS A POSSIBILITY THAT THE GEAR WAS NOT EXTENDED. HOWEVER, I KNOW THE GEAR SELECTOR WAS DOWN, AND THE STUDENT SWEARS HE HAD A GREEN LIGHT. IN ADDITION, THE LNDG GEAR WAS PARTLY OUT OF THE GEAR WELLS WHEN IT WAS JACKED UP. PRELIMINARY INSPECTION SHOWS NO DEFINITE GEAR DAMAGE. I FEEL (OR AT LEAST HOPE) THAT IT WAS GEAR COLLAPSE. PROPER RTES HAVE BEEN FILED, THERE WERE NO INJURIES AND ONLY MINOR DAMAGE. FAA HAS LISTED IT AS AN INCIDENT AND HAS MADE AN ON-SCENE EXAMINATION.
