Narrative:

My student and I experienced a collapsed landing gear on touchdown on runway 14 at ZZZ airport. My student was at the controls of grumman cougar GA-7 and I was instructor pilot for this training flight. The approach to the landing mishap was to be the fourth full stop landing at ZZZ. On downwind leg; my student lowered the landing gear and gear down was indicated. The aircraft response appeared normal for the landing gear coming down. Power was reduced to about 15 inches of mp and a 500 FPM descent was initiated. Final approach was flown with 30 degrees of flaps with normal approach power. Another gear check was made on base leg. During the flare to landing; approaching what seemed to be normal attitude and touchdown ht; I noticed what felt like the landing gear touching down lightly; however; it appeared the gear collapsed at this point and the aircraft settled onto the runway with propellers striking the surface. We skidded down the runway for what seemed like a long time and we then made an immediate emergency evacuate/evacuation. On postflt inspection; both left and right landing gear were out of the wheel wells and collapsed under the wings.
