SMA HAS CLOSE PROX TO SECOND SMA AFTER LNDG ON SAME RWY.

Narrative

THERE WERE SEVERAL ACFT EITHER ON THE GND AWAITING TKOF OR IN THE TFC PATTERN AT AUSTIN EXECUTIVE ARPT WHEN I APCHED ON THE 45 TO ENTER THE TFC PATTERN. ANOTHER ACFT; SMA A; ANNOUNCED THAT HE WAS 3 MI E. I ANNOUNCED THAT I WAS 2 MI E; THEN ANNOUNCED ENTERING L DOWNWIND FOR RWY 18. SMA A PLT ANNOUNCED L DOWNWIND FOR RWY 18. AS I TURNED BASE I ANNOUNCED MY BASE LEG; THEN SMA A PLT ANNOUNCED BASE. AS I TURNED FINAL I ANNOUNCED FINAL; FULL STOP; AND THEN SMA A ANNOUNCED FINAL. I MADE A WHEEL LNDG AND WAS UNABLE TO STOP UNTIL ABOUT 20 FT PAST THE LAST TXWY IN FRONT OF THE FBO. RATHER THAN TIE UP THE RWY BY TAXIING TO THE END; I ELECTED TO TURN 180 DEGS TO EXIT THE TXWY AND ANNOUNCED WHAT I WAS DOING. WHEN I TURNED THE ACFT I SAW SMA A COMING TOWARD ME ON THE RWY. HE HAD APPARENTLY LANDED JUST BEHIND ME AND WAS ON ROLLOUT. I EXITED THE RWY AS QUICKLY AS I COULD; AS I COULD NOT JUDGE HIS SPD AND WAS APPREHENSIVE OF A COLLISION. SMA A WAS OCCUPIED BY A STUDENT AND INSTRUCTOR. THE RWY IS 5000 FT LONG AND THIS TOOK PLACE IN THE FIRST 2/3 OF IT. I FEEL THAT THE OTHER AIRPLANE SHOULD NOT HAVE LANDED ON A RWY OF THAT LENGTH WITH ANOTHER ACFT STILL ON THE RWY. I DID NOT DISCUSS THE INCIDENT WITH THE INSTRUCTOR IN SMA A SO I DO NOT KNOW WHAT THEIR MOTIVATION WAS. HOWEVER; I CAN THINK OF NO SIT WHERE LNDG SO CLOSE BEHIND ANOTHER ACFT WOULD BE ACCEPTABLE. THIS INCIDENT WAS WITNESSED BY ANOTHER FLT INSTRUCTOR WHO WAS ON DOWNWIND WITH A STUDENT AND SAW THE OTHER AIRPLANE FOLLOWING ME. SHE STATED THAT IN HER VIEW THE OTHER ACFT SHOULD NOT HAVE FOLLOWED SO CLOSELY AND SHOULD HAVE DONE A GAR WHEN IT BECAME APPARENT THAT THEY WOULD LAND WHILE I WAS STILL ON THE RWY. THE INSTRUCTOR IN SMA A CERTAINLY WAS NOT TEACHING GOOD PROCS TO HIS STUDENT. THE PLT OF SMA A AND I WERE BOTH REMISS IN NOT COMMUNICATING WITH EACH OTHER IN THE PATTERN. I SHOULD HAVE ASKED HIM HIS POS; IF HE SAW ME; AND HIS INTENTIONS. I WOULD HAVE GONE AROUND MYSELF IF IT WOULD HAVE PREVENTED SUCH A DANGEROUS SIT. IF I HAD A PROB WITH MY ACFT; OR IF THE OTHER ACFT'S BRAKES HAD FAILED; A COLLISION MIGHT HAVE OCCURRED.
