Narrative:

Planned to do a couple of touch and goes. On the first landing, touched down softly on the approach end of runway 7R. As I advanced the throttle to go around again, I realized the propeller had hit. I immediately throttled back. The plane appeared to pull to the left. The left wing dropped first and the nose wheel must have folded back. The main gear was partially collapsed. The left gear more than the right. The nose wheel was in its well. The drain on the left tip tank was broken off and the propeller was, of course, bent. There appeared to be little other structural damage except to the gear doors. On final approach, both my husband and I went through 'gump'. The gear light showed green, the manual indicator for the nose wheel showed down and the gear horn did not sound.
