Narrative:

I was flying with a CFI on the afternoon of [date] at ZZZ for flight training for a complex endorsement. We departed ZZZ from runway xx and headed in a northerly direction; practiced slow flight and power off stalls and a planned simulated gear malfunction. We headed back for a landing at ZZZ. As we proceeded to land; the CFI tripped the circuit breaker for the landing gear to simulate a gear malfunction. When the gear light did not indicate the gear was down; we performed a go-around. We flew back north of ZZZ; lowered the gear manually; turned the circuit breaker back on; confirmed that the gear was down; and performed several more landings while remaining in the traffic pattern. While preparing to land again; the gear light indicated that the gear had not lowered. We performed a go-around and it was determined the right gear would not lower. At this point; the CFI took control of the aircraft. We spent at least 30 minutes trying to get the right gear to come down. The CFI contacted ZZZ and ultimately was able to make contact with the owner of a maintenance facility located at ZZZ. The CFI performed at least two low passes to allow the maintenance facility owner to try and observe the status of the right gear. He also flew the plane in slow flight while attempting cycle the gear and also attempted to manually lower the gear. The right gear repeatedly would not lock in place. The CFI also tried several steep turns to increase the G forces to see if the right gear could be locked in place. All of these were unsuccessful. As darkness was approaching; the CFI made the decision to perform a gear up landing because he did not want to face that in darkened conditions. The CFI successfully landed the plane gear up on runway xx.there were no injuries and the only damage known at this time is to the propeller; landing gear and underbelly of the aircraft.
