Narrative

THE QUAD CITY ARPT IS OPEN FROM 5 AM TO 11 PM DAILY. BTWN 11 PM AND 5 AM; ZAU WORKS THE AIRSPACE. WHEN THE CTLRS CLOSE THE TWR AT 11 PM; THE ARPT LIGHTS ARE OFF FOR RWY 5/23 AND RWY 13/31. ONLY RWY 9/27 IS LIGHTED. RWY 13/31 IS ALSO CLOSED FOR CONSTRUCTION. IF THE SYS MALFUNCTIONS; ALL LIGHTS COME ON ON HIGH INTENSITY. RWY 13/31 WAS SUPPOSED TO HAVE BEEN DISCONNECTED FROM THE SYS. SOMETIME AFTER THE CTLRS LEFT AT 11 PM ON AUG/XX/94; A MALFUNCTION OCCURRED AND ALL LIGHTS CAME UP ON HIGH -- INCLUDING THE RWY LIGHTS FOR RWY 13/31. THESE LIGHTS WERE ON UNTIL THE CTLRS CAME IN AT 5 AM AND TURNED THEM OFF. LUCKILY; NO ACFT CAME IN AND LANDED ON THAT RWY. THE RWY LIGHTS FOR RWY 13/31 SHOULD BE DISCONNECTED. THE RWY HAS BEEN CLOSED FOR OVER A YR. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATED THAT THE RWY OPENED ABOUT ONE MONTH AGO SO THAT THE ISSUE OF THE RWY LIGHTING IS A NON EVENT FOR THE FUTURE. MAINT SUPVR FAILED TO ADVISE ATC WHEN THEY RECONNECTED THE PWR LINES TO THE 'CLOSED' RWY. INTRAFAC COORD FELL DOWN.
