PA28 AT FWA LANDS AND HOLDS SHORT OF A C337 IN POSITION WAITING FOR TKOF.

Narrative

CESSNA CITATION DEP IFR WHILE PA28 WAS IN PATTERN DOING TOUCH AND GOES. THE CITATION DEVELOPED AN EMER DUE TO A DOOR OPENING IN FLT AFTER BEING HANDED OFF TO THE CTR. I VECTORED CITATION TO THE ARPT WHERE IT LANDED AT A HIGHER THAN NORMAL SPEED. I SEQUENCED THE PA28 ON THE DOWNWIND TO FOLLOW THE CITATION. WHEN THE CITATION ROLLED PAST TXWY Y I PUT THE C337 IN POSITION (2200 FT FROM THRESHOLD). THE CITATION ENDED UP ROLLING ALMOST TO THE END OF THE RWY. I LOST SITE OF THE PA28; BUT FELT I HAD TIME SINCE THE LAST TIME I SAW THE PA28 ON A MID FIELD DOWNWIND DOING A REQUESTED 360 TO ALLOW THE CITATION TO LAND. I WAS DISTRACTED WATCHING FOR THE CITATION TO CLR. WHEN I TURNED AROUND TO CHK FOR THE PA28 AND TO CLR THE C337 FOR TKOF I SPOTTED THE PA28 ABOUT TO TOUCHDOWN. I DIDN'T ISSUE TO A GAR BECAUSE I FELT IT WOULD HAD BEEN MORE DANGEROUS THAN ALLOWING THE PA28 TO LAND. THE PA28 STOPPED OVER 100 FT BEHIND THE C337; THEN CLRED THE RWY. THE PA28 PLT SAID HE SAW THE C337 SITTING ON THE RWY; BUT KNEW HE COULD LAND AND STOP SOON ENOUGH. HINDSIGHT WOULD DICTATE THAT I SHOULD NOT HAD PUT THE C337 INTO POSITION AT THE INTERSECTION AFTER THE CITATION LANDED TO ALLOW MYSELF MORE TIME FOR THE EMER (OPEN DOOR) TO RESOLVE ITSELF. I SHOULD ALSO HAD INSTRUCTED THE PA28 TO CONTINUE DOING 360'S ON THE DOWNWIND UNTIL THIS SITUATION WITH THE CITATION ENDED. A VERY VALUABLE LESSON WAS LEARNED TODAY. 'DON'T TRY TO DO TO MANY THINGS WHILE AN ACFT WITH AN EMER CAN DISTRACT YOUR ATTENTION FROM THE OP.' ALSO I SHOULD HAD REQUESTED ASSISTANCE FROM OTHER CTLRS OR SUPVR ON BREAK; BECAUSE MORE EYES AND EARS HELP KEEP THINGS SAFER. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR SAID HE SHOULD NOT HAVE BEEN COMBINED WITH THE APCH CTL POSITIONS WHILE WORKING THE LCL POSITION AND SHOULD HAVE CALLED FOR ASSISTANCE. HE SAID THE SUPVR AND THE OTHER CTLRS WERE IN THE BREAK ROOM. HE SAID HE BECAME DISTR WITH THE CITATION TURNING OFF LONG AND FORGOT ABOUT THE PA28 THAT WAS CLRED TO LAND. HE SAID THE FACILITY HAS A DIFFERENT POLICY ON STAFFING NOW.
