EVV TWR HAS BEEN HAVING DIFFICULTY GETTING A CAB PANE REPAIRED BECAUSE NO ONE IN THE AREA IS WILLING TO DO THE WORK.

Narrative

THE NORTHERNMOST WINDOW ON THE E SIDE OF THE TWR CAB IS NO LONGER COMPLETELY TRANSPARENT. THE SEAL BTWN THE 2 PANES OF GLASS FAILED SEVERAL MONTHS AGO ALLOWING CONDENSATION TO FORM INSIDE THE WINDOW ON A REGULAR BASIS; AND OF COURSE OBSCURING THE VIEW WHEN THIS CONDENSATION WAS PRESENT. THE AMOUNT OF CONDENSATION HAS BEEN SO GREAT THE RESIDUE LEFT BEHIND HAS MADE A LARGE PORTION OF THE WINDOW PERMANENTLY OPAQUE. THIS POSES A SERIOUS SAFETY HAZARD; AS IT OBSCURES THE VIEW OF THE APCH END OF THE MAIN RWY; RWY 22; USED FOR NEARLY ALL COMMUTER AND A LARGE PERCENTAGE OF CPR TFC; FROM THE LCL CTL POS. I HAVE PERSONALLY EXPERIENCED NOT BEING ABLE TO IMMEDIATELY LOCATE AN ACFT ON SEVERAL OCCASIONS BECAUSE OF THIS PROB. IT IS MY UNDERSTANDING THAT THERE IS NOT A LCL GLASS COMPANY WILLING TO ACCEPT THE JOB AND THAT EFFORTS ARE BEING MADE TO LOCATE A CONTRACTOR FROM ONE OF THE LARGER METROPOLITAN AREAS NEAR EVANSVILLE. HOWEVER; THIS PROB HAS GROWN TO A POINT THAT ACTION NEEDS TO BE TAKEN NOW; BEFORE IT CONTRIBUTES TO A SERIOUS INCIDENT. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATED THE FACILITY NOW HAS 2 BIDDERS COMPETING TO REPAIR THE FAULTY WINDOW IN THE TWR. HE SAID BOTH BIDDERS ARE FROM OUT OF TOWN; 100 MI AWAY. I ASKED ABOUT SPOTTERS TO HELP LOCATE TFC WHEN TFC PICKS UP. THE RPTR SAID THE TWR HAS A BRITE RADAR THAT HELPS AND MOST CIC'S SPOT WHEN IT IS REAL BUSY. THE FACILITY WORKS ABOUT 500 OPS A DAY (PART TIME TWR); 75 OF WHICH ARE COMMUTERS.
