Narrative:
While acting as sic on hawker, the captain began the approach on ILS 5 at gon airport, ct. The WX was reported as 1 1/2 mi visibility, 5000 ft RVR, 200 ft ceiling in fog. Wind 240 degrees at 8 KTS, wet runway. The captain was cleared for the approach and at 400 ft I observed the runway lead-in lights and the runway environment. I told the captain what I saw and he confirmed he had the runway and landed. Our reference speed was 114 KIAS and we landed at around the 3500-4000 ft mark. After landing, the captain applied brakes and lift dump. He then told me he had poor braking action and asked for my assistance. We both applied brakes, however, this was insufficient to avert going off the end of the runway. We came to rest approximately 90 yards off the end, and got out of the aircraft and pined the gear. There was no damage to the runway nor its lighting. There was no damage to the aircraft, however, there is a maintenance facility which is cleaning and carrying out the necessary inspections and no passenger was hurt nor injured. I think that the main contributing factor was the poor braking from the aircraft and landing with a tailwind. This aircraft also does not have any thrust reversers and is completely reliant on brakes and lift dump.

Title: HS125-600 FLC FAILED TO STOP AND WENT OFF END OF RWY AFTER FAILING TO STOP ACFT AFTER LNDG AT THE 4000 FT MARKER DOWNWIND ON A WET RWY WITH NO THRUST REVERSERS.
Narrative: WHILE ACTING AS SIC ON HAWKER, THE CAPT BEGAN THE APCH ON ILS 5 AT GON ARPT, CT. THE WX WAS RPTED AS 1 1/2 MI VISIBILITY, 5000 FT RVR, 200 FT CEILING IN FOG. WIND 240 DEGS AT 8 KTS, WET RWY. THE CAPT WAS CLRED FOR THE APCH AND AT 400 FT I OBSERVED THE RWY LEAD-IN LIGHTS AND THE RWY ENVIRONMENT. I TOLD THE CAPT WHAT I SAW AND HE CONFIRMED HE HAD THE RWY AND LANDED. OUR REF SPD WAS 114 KIAS AND WE LANDED AT AROUND THE 3500-4000 FT MARK. AFTER LNDG, THE CAPT APPLIED BRAKES AND LIFT DUMP. HE THEN TOLD ME HE HAD POOR BRAKING ACTION AND ASKED FOR MY ASSISTANCE. WE BOTH APPLIED BRAKES, HOWEVER, THIS WAS INSUFFICIENT TO AVERT GOING OFF THE END OF THE RWY. WE CAME TO REST APPROX 90 YARDS OFF THE END, AND GOT OUT OF THE ACFT AND PINED THE GEAR. THERE WAS NO DAMAGE TO THE RWY NOR ITS LIGHTING. THERE WAS NO DAMAGE TO THE ACFT, HOWEVER, THERE IS A MAINT FACILITY WHICH IS CLEANING AND CARRYING OUT THE NECESSARY INSPECTIONS AND NO PAX WAS HURT NOR INJURED. I THINK THAT THE MAIN CONTRIBUTING FACTOR WAS THE POOR BRAKING FROM THE ACFT AND LNDG WITH A TAILWIND. THIS ACFT ALSO DOES NOT HAVE ANY THRUST REVERSERS AND IS COMPLETELY RELIANT ON BRAKES AND LIFT DUMP.
