TWR LCL CTLR REQUESTED FLC RPT THE OM WHEN ON AN ILS APCH. THEY FAILED TO RPT IT BECAUSE THEY LOST THE DME'S TEMPORARILY; BUT COULD HAVE RPTED THEIR POS RELATIVE TO THE GS. TWR RELEASED ANOTHER ACFT TO TKOF TOWARD APCHING ACFT.

Narrative

ON FEB/FRI/96; WE CONDUCTED AN IFR FLT FROM 2B6 TO BDR. NY APCH VECTORED US TO THE FINAL APCH COURSE AT 2000 FT MSL FOR RWY 6 AT BDR. WHEN NY SWITCHED US OVER TO THE BDR TWR WE HAD ALREADY BEEN ESTABLISHED ON THE ILS RWY 6. ON THE TWR FREQ WE RPTED; ESTABLISHED ON THE ILS RWY 6. THE TWR ADVISED US TO RPT STANE INTXN. WHEN WE DOUBLE-CHKED THE APCH CHART FOR RWY 6; WE NOTICED THAT WE LOST THE DME INDICATION. WHEN THE DME INDICATION CAME BACK; WE CHKED OUR POS ON THE ILS AND FOUND OUT THAT WE ALREADY PASSED STANE. BY THAT TIME WE HAD THE RWY IN SIGHT AND RPTED THIS TO TWR. THERE WE NOTICED A SINGLE ENG PIPER IN A L TURN; WHICH TOOK OFF FROM RWY 24; I BELIEVE FOR TOUCH AND GOES. THIS PLANE CAME NOT NEAR US; WE HAD TO TAKE NO ACTIONS AND CONTINUED OUR APCH. THE PIPER WAS APPROX 1 1/2 MI AWAY AND ABOUT 500 FT LOWER THAN US. IT WAS JUST A SURPRISE FOR US SEEING ANOTHER AIRPLANE; WHICH TOOK OFF FROM THE OPPOSITE RWY. AFTER WE LANDED ON RWY 6; THE TWR ADVISED US TO RPT STANE INTXN THE NEXT TIME; BECAUSE THEY CANNOT SEE OUR POS ON THE ILS. I BELIEVE; THAT BY THE TIME WE HAD BEEN ADVISED TO RPT STANE; WE HAD BEEN RIGHT OVER IT; IF NOT ALREADY PASSED IT. IF WE DID NOT LOSE OUR DME INDICATION FOR A FEW SECONDS; WE COULD HAVE VERIFIED OUR POS ON THE ILS FOR SURE RIGHT AWAY. AS WE HAD NOT A GREAT VFR DAY THAT MORNING; I WAS WONDERING WHY THE TWR LET SOMEBODY TKOF ON AN OPPOSITE RWY WHILE THERE IS AN IFR INBOUND ON THE ILS.
