SMA ACFT DOING ACROBATIC MANEUVERS ENTERS SPIN AT LOW ALT. RECOVERS AT 20 FT AGL.

Narrative

I WAS GOING FROM VERO BEACH TO MELBOURNE TO SHOOT SOME IFR APCHS WITH A RENTED SMA CATEGORY UTILITY; SPIN APPROVED. AFTER THE TKOF; I DEPARTED EBOUND TO FOLLOW THE COASTLINE. I KNEW THAT SOME OF MY FRIENDS WERE THERE. SO I ASK THE TWR TO MAINTAIN THE AREA IN FRONT OF THE BEACH UP TO 1500 FT AND I GOT THAT. SO THE TEMPTATION HAS BEEN GREATER THAN MY JUDGEMENT. I PERFORMED A SERIES OF SNAP ROLL; AILERON ROLL; AND STEEP TURN. EVERYTHING WENT GOOD. I WAS ALWAYS ABOVE 1000 FT AND NEVER CLOSE TO THE BEACH. BEFORE LEAVING I DECIDED TO STALL THE AIRPLANE. I DON'T KNOW WHAT BUT THE AIRPLANE FELL ON A SIDE; THAT IN OTHER WORDS IT WAS A VERY QUICK SPIN. I WAS AT 900 FT; A FEW MOMENTS TO REALIZE THAT; AND I PERFORMED THE PROCS TO RECOVER FROM A SPIN; BUT I RECOVERED THE ACFT AT ABOUT 20 FT ON THE WATER. I GOT SCARED. ANYWAY EVEN IN THIS EVENT I WAS NOT CLOSE ENOUGH TO THE BEACH TO CREATE ANY DANGER FOR ANYBODY; EXCEPT ME AND MY FRIEND THAT WAS A PAX. WE WERE NOT WEARING PARACHUTES; AND I'VE NOT BEEN ALWAYS AT 1500 FT MIN. AFTER THAT I CAME BACK TO LAND.
