Narrative:

We were practicing commercial power-off 180 degree landings for my upcoming commercial check ride. We had taken off on runway 13; and proceeded to make right closed traffic on runway 17 right; cleared for short approach. [Flight instructor] demonstrated one power off 180 to me; and then I made 5 myself; for a total of 6 approaches. On the 4th or 5th approach; the landing gear did not indicate a green light to signal the gear down and locked after lowering the handle. This issue has happened to me twice before in this aircraft over the past 2 weeks- once on my first flight in the aircraft while approaching to land at ZZZ and once on approach to land in ZZZ1. All three times this issue has occurred; I was able to cycle the gear back up; and back down; with positive green light indication that the landing gear was then down and locked. Several days before this flight; the aircraft while being flown by another pilot had a similar issue which was not resolved by cycling the landing gear; and the aircraft was grounded until maintenance inspected it. On the 6th approach to landing of this flight; I was setting up for another power off 180 approach. Abeam the intended touchdown point (the 1000 foot markers) on runway 17 right; I went through the setup for the power off 180- as I performed each step; I verbalized what I was doing out loud. I reduced the throttle to idle. I applied carburetor heat; and lowered the landing gear handle to the down position. I then lowered 10 degrees of wing flaps.I looked at the mirror on the right wing to see that the gear was physically down; and the green 'gear down' light illuminated on the instrument panel. I turned right base; angled toward the end of the runway and put in 20 degrees of wing flaps. As I lined up on the centerline of the runway I added full wing flaps as I crossed the threshold of runway 17 right. At no time did the landing gear warning horn ever sound; nor did I ever raise or physically touch the landing gear operating lever after putting it down on the downwind leg of my approach. The aircraft settled and impacted the runway with a loud grinding sound. Smoke began to fill the cockpit as I held the yoke full to the rear to keep pressure off the nose and induce aerodynamic braking; while maintaining directional control with the rudder pedals. I also saw [the flight instructor] holding the yoke back as well during the incident. When the aircraft came to a stop on the runway; there was still smoke in the cockpit; and [the flight instructor] ordered me to evacuate the aircraft. I exited through the left door; and moved aft of the tail of the aircraft. By the time I had reached the tail of the aircraft I noticed [the flight instructor] had not yet exited; and and called out to her. I approached the right side door just behind the right wing as she came out of the aircraft safely. [The flight instructor] and I then walked to the grass on the west edge of runway 17 right. Crash fire rescue and airport operations personnel arrived shortly thereafter.
