Narrative:
On jan/mon/02 at about XA00, I was making a takeoff on runway 23 at the yng airport. Although there had been snow the night before, and this runway was closed when I arrived at about XB15, the snow had been removed and the runway appeared to be bare and wet when I taxied onto it for takeoff. Just east of the intersection of this runway and the main instrument runway 14/32, at a speed of about 80 KTS, I encountered an area of slush which due to its gray color and the concrete color of the runway was almost invisible. When I attempted to raise the landing gear after airborne, there was a failure of the nose gear actuator. I was unable to get a down and locked indication on the nose gear. I did 2 fly-by-the-tower passes and they told me that all landing gear looked normal. I declared an emergency and on landing, the nose gear collapsed. I went back to the area where I encountered the slush and found it to be right on the runway centerline, about 8-10 ft in diameter, with a depth of 2-3 inches. Based upon the initial findings of the maintenance department, the slush encounter damaged one or both of the gear doors such that the landing gear tried to retract through it, and broke the actuator. The slush pile on this runway in this spot was likely the result of plowing operations on the main runway. This runway and the intersection should have been inspected after the plowing operation was finished on the other runway. Runway 23 should have been closed until the slush area was removed.

Title: TWIN TURBOPROP PLT STRUCK ICE DURING TKOF AT A RWY INTXN CAUSING DAMAGE TO THE NOSE GEAR ACTUATOR ASSEMBLY RESULTING IN THE NOSE GEAR COLLAPSING DURING THE SUBSEQUENT EMER LNDG.
Narrative: ON JAN/MON/02 AT ABOUT XA00, I WAS MAKING A TKOF ON RWY 23 AT THE YNG ARPT. ALTHOUGH THERE HAD BEEN SNOW THE NIGHT BEFORE, AND THIS RWY WAS CLOSED WHEN I ARRIVED AT ABOUT XB15, THE SNOW HAD BEEN REMOVED AND THE RWY APPEARED TO BE BARE AND WET WHEN I TAXIED ONTO IT FOR TKOF. JUST E OF THE INTXN OF THIS RWY AND THE MAIN INST RWY 14/32, AT A SPD OF ABOUT 80 KTS, I ENCOUNTERED AN AREA OF SLUSH WHICH DUE TO ITS GRAY COLOR AND THE CONCRETE COLOR OF THE RWY WAS ALMOST INVISIBLE. WHEN I ATTEMPTED TO RAISE THE LNDG GEAR AFTER AIRBORNE, THERE WAS A FAILURE OF THE NOSE GEAR ACTUATOR. I WAS UNABLE TO GET A DOWN AND LOCKED INDICATION ON THE NOSE GEAR. I DID 2 FLY-BY-THE-TWR PASSES AND THEY TOLD ME THAT ALL LNDG GEAR LOOKED NORMAL. I DECLARED AN EMER AND ON LNDG, THE NOSE GEAR COLLAPSED. I WENT BACK TO THE AREA WHERE I ENCOUNTERED THE SLUSH AND FOUND IT TO BE RIGHT ON THE RWY CTRLINE, ABOUT 8-10 FT IN DIAMETER, WITH A DEPTH OF 2-3 INCHES. BASED UPON THE INITIAL FINDINGS OF THE MAINT DEPT, THE SLUSH ENCOUNTER DAMAGED ONE OR BOTH OF THE GEAR DOORS SUCH THAT THE LNDG GEAR TRIED TO RETRACT THROUGH IT, AND BROKE THE ACTUATOR. THE SLUSH PILE ON THIS RWY IN THIS SPOT WAS LIKELY THE RESULT OF PLOWING OPS ON THE MAIN RWY. THIS RWY AND THE INTXN SHOULD HAVE BEEN INSPECTED AFTER THE PLOWING OP WAS FINISHED ON THE OTHER RWY. RWY 23 SHOULD HAVE BEEN CLOSED UNTIL THE SLUSH AREA WAS REMOVED.
