Narrative:

Upon arrival in hpn, flew an ILS approach to runway 16. WX was approximately 150 broken, 7 mi visibility and winds 160/04. It had been raining earlier, but had ceased at the time of our arrival. Consequently the runway was wet. Approach was normal flaps 40 degrees. Aircraft weight was approximately 90000 pounds and approach speed 135 KTS. Touched down on speed and approximately 1000' down runway. Runway length 6548'. Upon T/D went into reverse thrust and aircraft appeared to be slowing down normally. When brakes were applied, skidding occurred and anti-skid was cycling. Increased reverse thrusting and braking; however, was unable to stop aircraft prior to departing end of runway. Nose wheel and mains in grass approximately 5' from pavement. Speed at time of runway departure was very close if not below slow taxi speed. Consequently no apparent damage done to aircraft. No personnel were injured. Tower had emergency equipment and ground personnel to meet aircraft. I instructed tower to relay to ground personnel to use extreme caution so as not to pull tail cone exit handle. Tower did relay message and gave me a frequency to talk directly to ground personnel (122.95). Again I told them to not pull tail cone exit handle. They said they were unfamiliar with the aircraft and would wait until ground handling personnel arrived. Upon their arrival, they pulled the incorrect handle and tail cone came off. Passenger and F/a's had been previously briefed and were aware of the situation. At this time they exited through the rear of the aircraft and were bussed to the terminal.

Title: ACR LNDG ON WET RWY SLIDES SLOWLY OFF RWY INTO GRASS.

Narrative: UPON ARR IN HPN, FLEW AN ILS APCH TO RWY 16. WX WAS APPROX 150 BROKEN, 7 MI VISIBILITY AND WINDS 160/04. IT HAD BEEN RAINING EARLIER, BUT HAD CEASED AT THE TIME OF OUR ARR. CONSEQUENTLY THE RWY WAS WET. APCH WAS NORMAL FLAPS 40 DEGS. ACFT WT WAS APPROX 90000 LBS AND APCH SPD 135 KTS. TOUCHED DOWN ON SPD AND APPROX 1000' DOWN RWY. RWY LENGTH 6548'. UPON T/D WENT INTO REVERSE THRUST AND ACFT APPEARED TO BE SLOWING DOWN NORMALLY. WHEN BRAKES WERE APPLIED, SKIDDING OCCURRED AND ANTI-SKID WAS CYCLING. INCREASED REVERSE THRUSTING AND BRAKING; HOWEVER, WAS UNABLE TO STOP ACFT PRIOR TO DEPARTING END OF RWY. NOSE WHEEL AND MAINS IN GRASS APPROX 5' FROM PAVEMENT. SPD AT TIME OF RWY DEP WAS VERY CLOSE IF NOT BELOW SLOW TAXI SPD. CONSEQUENTLY NO APPARENT DAMAGE DONE TO ACFT. NO PERSONNEL WERE INJURED. TWR HAD EMER EQUIP AND GND PERSONNEL TO MEET ACFT. I INSTRUCTED TWR TO RELAY TO GND PERSONNEL TO USE EXTREME CAUTION SO AS NOT TO PULL TAIL CONE EXIT HANDLE. TWR DID RELAY MESSAGE AND GAVE ME A FREQ TO TALK DIRECTLY TO GND PERSONNEL (122.95). AGAIN I TOLD THEM TO NOT PULL TAIL CONE EXIT HANDLE. THEY SAID THEY WERE UNFAMILIAR WITH THE ACFT AND WOULD WAIT UNTIL GND HANDLING PERSONNEL ARRIVED. UPON THEIR ARR, THEY PULLED THE INCORRECT HANDLE AND TAIL CONE CAME OFF. PAX AND F/A'S HAD BEEN PREVIOUSLY BRIEFED AND WERE AWARE OF THE SITUATION. AT THIS TIME THEY EXITED THROUGH THE REAR OF THE ACFT AND WERE BUSSED TO THE TERMINAL.
