Narrative:

I was cleared for runway 28R. At the point I was to turn final, the tower changed me to runway 28L. I continued my base leg and turned final on runway 28L. I felt I was low, so I applied some power to slow my descent. As I approached the runway, I pulled the remainder of the power. As I started the roundout, the airplane ballooned. I continued to hold back pressure. The airplane stalled approximately 10 ft above the runway surface and the nosewheel contacted first and collapsed. I tried to hold the nose off the ground while I shut down the engine, secured the fuel and killed the magnetos and master switch. Unfortunately, the propeller had struck the runway surface prior to shutdown.

Title: PLT OF AN SMA SEL STALLED AND DROPPED ONTO THE NOSEWHEEL DURING LNDG FLARE CAUSING THE NOSE GEAR TO COLLAPSE.

Narrative: I WAS CLRED FOR RWY 28R. AT THE POINT I WAS TO TURN FINAL, THE TWR CHANGED ME TO RWY 28L. I CONTINUED MY BASE LEG AND TURNED FINAL ON RWY 28L. I FELT I WAS LOW, SO I APPLIED SOME PWR TO SLOW MY DSCNT. AS I APCHED THE RWY, I PULLED THE REMAINDER OF THE PWR. AS I STARTED THE ROUNDOUT, THE AIRPLANE BALLOONED. I CONTINUED TO HOLD BACK PRESSURE. THE AIRPLANE STALLED APPROX 10 FT ABOVE THE RWY SURFACE AND THE NOSEWHEEL CONTACTED FIRST AND COLLAPSED. I TRIED TO HOLD THE NOSE OFF THE GND WHILE I SHUT DOWN THE ENG, SECURED THE FUEL AND KILLED THE MAGNETOS AND MASTER SWITCH. UNFORTUNATELY, THE PROP HAD STRUCK THE RWY SURFACE PRIOR TO SHUTDOWN.
