X LANDED ON OCCUPIED RWY.

Narrative

X WAS EXECUTING THE LAKE PARKER ARR (SEE ATTACHED CHART) TO RWY 27R. EVERYTHING PROCEEDED NORMALLY DESPITE THE FAIRLY HVY TFC. AS I DID MY DOWNWIND (POINT A ON CHART); I WAS FOLLOWING 2 OTHER ACFT. A DC-3 WAS PROCEEDING WIDE OF MY ACFT FOR A LNDG ON RWY 27L. HE WAS AT 1500 FT DSNDING. I WAS AT 1000 FT DSNDING; TURNING BASE. A HAWKER JET WAS ON A STRAIGHT IN TO RWY 27L. THE PLANE I WAS FOLLOWING WAS A CESSNA 182. THE FIRST AIRPLANE FOR RWY 27R WAS A HOME BUILT BIPLANE. HE WAS 'CLRED TO LAND.' ALL OF THESE ACFT WERE EXECUTING THE LAKE PARKER ARR AND/OR ADDITIONAL INSTRUCTIONS FROM THE TWR. AS I TURNED BASE; THE CESSNA 182 WAS 'CLRED TO LAND' AND ABOUT THIS TIME A 'POPUP' APPEARED. A LOW WING PIPER (WHICH THE TWR LATER CALLED A 'SARATOGA') CAME INTO VIEW FROM MY 10 O'CLOCK LOW (FROM THE NE; SEE POINT B ON CHART). IT WAS OBVIOUS TO ME THAT HE HAD NOT EXECUTED A 'LAKE PARKER' ARR AND HE CUT IN BTWN THE CESSNA 182 AND MY PLANE. THE TWR CTLR SAW HIM BEFORE I DID AND MADE SEVERAL QUICK REFS TO THE 'LOW WING PIPER.' I WAS IN A LOW WING EXPERIMENTAL AND INITIALLY THOUGHT HE MIGHT BE REFERRING TO ME. THEN I SAW THE PIPER. THE CTLR TOLD THE PIPER TO FOLLOW THE CESSNA WHICH SEEMED APPROPRIATE SINCE HE NOW WAS BTWN US. I FOLLOWED THE PIPER. I STILL HAD THE DC-3 OUT TO MY L AND THE HAWKER ON AN APCH TO RWY 27L. NO TURNS SEEMED REASONABLE. I SLOWED MY PLANE AS MUCH AS POSSIBLE TO SPACE MYSELF BEHIND THE PIPER. THE PIPER LANDED ON RWY 27R AND KEPT THE RWY. BY NOW I WAS COMMENCING CORRECTIVE ACTION. THE PIPER STAYED SHORT ON RWY 27R AND THE CTLR TOLD HIM TO HOLD UP; AS IT 'APPEARED' ANOTHER PLANE WOULD PASS OVER HIM AND LAND LONG. I WENT R OF THE PIPER AT ABOUT 200 FT AGL. AFTER I PASSED OVER AND BEYOND THE PIPER; I SET UP AND EXECUTED A NORMAL LNDG ABOUT MID-FIELD. THE TWR DID NOT GIVE ME ADDITIONAL INSTRUCTIONS. THE CTLR WAS TALKING TO THE PIPER.
