Low time pilot of a Cessna 172 lost control of his aircraft on landing.

Narrative

I was on approach; landing on Runway 30. Weather was clear; calm winds; unlimited visibility. My downwind; base and final approach were textbook. When I was within approximately 5 FT from the ground and flaring the aircraft; the plane seemed to fall out of flare and hit the ground hard. First the rear landing gear and then the front landing gear. It was a hard landing. I immediately attempted to level the aircraft as it was back in flight; again about 5 or so feet from the ground. I bounced and hit again. I controlled the aircraft down the centerline; slowed and exited and cleared the runway to the taxiway. I parked the aircraft under its own power in front of the FBO. Upon inspection of the aircraft and airframe; the firewall was slightly buckled; the right rudder pedal was stuck; the yoke assembly would not operate properly and there was a slight oil leak from the front nose wheel assembly. I believe the causal factor might have been caused by simply a windshear anomaly coupled with perhaps some fatigue. The lesson I learned is to stay alert and pay attention to your environment at all times. Landings are one of the most critical path moments in flying the aircraft. I make it a common and regular event to practice my pattern flying and landings. In addition; I will make it a common practice to spend a few hours per month with a CFII; to obtain recommendations and suggestions on my flying habits.
