Sequence of Events
The pilot reported that after takeoff, he remained in the traffic pattern to conduct touch and go landings. A final approach was flown at 65 knots with full flaps extended. He believed he was holding full up elevator control pressure when the airplane landed hard. The aircraft bounced and porpoised over onto the nose landing gear.
Inadvertent Power Application
The pilot stated that his hand was still on the throttle and he inadvertently applied power. The airplane became airborne again, and he noted a loss of elevator control.
Control and Landing
Elevator trim was used to fly the airplane around the traffic pattern for a final landing. The pilot successfully landed the aircraft using trim for pitch control.
Damage
Bent structure from the collapsed nose landing gear impinged on the cockpit control column, likely restricting elevator control movement.
