Incident occurred during a training flight at kprc, including conducting power off 180S, a landing maneuver that involves power idle from pattern altitude to the spot of intended landing. On short final an excessive decent rate was noticed and power was reintroduced to initiate a go-around. Initiation of the go-around was too late and crew were unable to prevent a hard landing. After the initial hard landing the aircraft was able to climb away from the runway. The hard landing caused concern and troubleshooting measures were exercised. Crew then made a low approach and asked kprc tower for a visual inspection of the gear. Tower advised the gear seemed to be down and locked. The crew decided to complete a soft field landing just in case there was damage to the nose gear. Crew completed the landing and held the nose off the runway for as long as possible before the nose and prop struck the runway. Upon nose gear touching down, the nose gear collapsed causing damage to prop, gear doors, lower cowl, and gear tunnel. It was also observed that the initial hard landing had not only caused the nose gear tire to burst but it had also broken all four mounting lugs off of the nose gear strut actuator attach fitting, causing the nose gear to collapse.
