Narrative:

While conducting IOE to unv, I moved the parking brake handle to illustrate a point and to reach a screw that needed to be resecured. Upon arrival at our destination, we canceled IFR and flew a normal visual approach to runway 24. While turning from base to final, unicom advised the winds were 280 degrees at 19 KTS gusting to 25 KTS. On touchdown on the centerline, the aircraft decelerated faster than normal, and felt like the main wheels were locked. Knowing the aircraft brakes to be touchy, I twice commanded the first officer to not touch the brakes. At my second command, he responded that his feet were flat on the floor. I then ensured the parking/emergency brake was completely disengaged. I was unable to maintain directional control as the aircraft continued to slow, and the aircraft turned approximately 135 degrees and came to rest with 1 main gear and the nose gear off the runway surface. The left engine was shut down using the emergency procedure, as it was over mud/grass, and the aircraft subsequently shut down. No injuries were reported, and the passenger deplaned into a van. Both main tires (one on each main gear) were flat, and I did observe a thin layer of ice on the ungrooved section of runway on which the aircraft came to rest. Supplemental information from acn 428764: I was PF on my second day, first leg of IOE. I used rudder to maintain runway centerline. As the aircraft decelerated below 70 KIAS, I was not able to maintain directional control via rudder pedals (use of the rudder). Right main tire was still on runway pavement. We secured left engine via feather lever. The right engine was secured via normal shutdown procedures. The captain asked the passenger if they were ok. (I did not hear their responses because I still had my headset on and the noise from radio communications.) when I disembarked the aircraft and stepped onto runway edge, I noticed it was very slick (ice) -- especially on the white paint of the runway edge marking. We postflted aircraft, proceeded in to terminal and the captain contacted company.

Title: A BA3200 LANDS AT UNV, PA, WITH THE PARKING BRAKE SET, EFFECTIVELY LOCKING THE WHEELS. THE ACFT YAWS 135 DEGS AND SKIDS OFF TO THE SIDE OF THE RWY, WITH THE L MAIN GEAR AND NOSEWHEEL OFF THE RWY.

Narrative: WHILE CONDUCTING IOE TO UNV, I MOVED THE PARKING BRAKE HANDLE TO ILLUSTRATE A POINT AND TO REACH A SCREW THAT NEEDED TO BE RESECURED. UPON ARR AT OUR DEST, WE CANCELED IFR AND FLEW A NORMAL VISUAL APCH TO RWY 24. WHILE TURNING FROM BASE TO FINAL, UNICOM ADVISED THE WINDS WERE 280 DEGS AT 19 KTS GUSTING TO 25 KTS. ON TOUCHDOWN ON THE CTRLINE, THE ACFT DECELERATED FASTER THAN NORMAL, AND FELT LIKE THE MAIN WHEELS WERE LOCKED. KNOWING THE ACFT BRAKES TO BE TOUCHY, I TWICE COMMANDED THE FO TO NOT TOUCH THE BRAKES. AT MY SECOND COMMAND, HE RESPONDED THAT HIS FEET WERE FLAT ON THE FLOOR. I THEN ENSURED THE PARKING/EMER BRAKE WAS COMPLETELY DISENGAGED. I WAS UNABLE TO MAINTAIN DIRECTIONAL CTL AS THE ACFT CONTINUED TO SLOW, AND THE ACFT TURNED APPROX 135 DEGS AND CAME TO REST WITH 1 MAIN GEAR AND THE NOSE GEAR OFF THE RWY SURFACE. THE L ENG WAS SHUT DOWN USING THE EMER PROC, AS IT WAS OVER MUD/GRASS, AND THE ACFT SUBSEQUENTLY SHUT DOWN. NO INJURIES WERE RPTED, AND THE PAX DEPLANED INTO A VAN. BOTH MAIN TIRES (ONE ON EACH MAIN GEAR) WERE FLAT, AND I DID OBSERVE A THIN LAYER OF ICE ON THE UNGROOVED SECTION OF RWY ON WHICH THE ACFT CAME TO REST. SUPPLEMENTAL INFO FROM ACN 428764: I WAS PF ON MY SECOND DAY, FIRST LEG OF IOE. I USED RUDDER TO MAINTAIN RWY CTRLINE. AS THE ACFT DECELERATED BELOW 70 KIAS, I WAS NOT ABLE TO MAINTAIN DIRECTIONAL CTL VIA RUDDER PEDALS (USE OF THE RUDDER). R MAIN TIRE WAS STILL ON RWY PAVEMENT. WE SECURED L ENG VIA FEATHER LEVER. THE R ENG WAS SECURED VIA NORMAL SHUTDOWN PROCS. THE CAPT ASKED THE PAX IF THEY WERE OK. (I DID NOT HEAR THEIR RESPONSES BECAUSE I STILL HAD MY HEADSET ON AND THE NOISE FROM RADIO COMS.) WHEN I DISEMBARKED THE ACFT AND STEPPED ONTO RWY EDGE, I NOTICED IT WAS VERY SLICK (ICE) -- ESPECIALLY ON THE WHITE PAINT OF THE RWY EDGE MARKING. WE POSTFLTED ACFT, PROCEEDED IN TO TERMINAL AND THE CAPT CONTACTED COMPANY.

A BA3200 lands at unv, PA, with the parking brake set, effectively locking the wheels. The aircraft yaws 135 degrees and skids off to the side of the runway, with the left main gear and nosewheel off the runway.
