The pilot was approaching to land after a period of solo practice in the training area. The touchdown was moderately heavy and the aircraft bounced. It then commenced to porpoise, until the nosewheel partially collapsed and the propeller struck the runway. The pilot was probably concerned because two other aircraft were approaching to use the same runway, and she perceived a need to vacate the area at the first taxyway. Witnesses reported that the aircraft did not flare for touchdown, and that it appeared that the pilot had tried to force it onto the ground.
