Narrative:
At approximately XA50 am, in heavy snow, we aborted a takeoff due to contamination on the wing. We had an extended taxi time plus a hold-short time to let another aircraft depart. By the time we were on the runway, there was snow on the wing. During the takeoff roll, it was apparent that the wing still had a little snow on it. We aborted the takeoff due to possible contamination, and went back to the gate to make sure we were deiced and had a clean airframe. Supplemental information from acn 570098: a takeoff was aborted due to possible contamination on the wing surface. Upon final inspection of the wings before takeoff, the wings appeared wet with water droplets and the winglets had a dusting of snow. On the takeoff roll and at approximately 60 KTS, I noticed what appeared to be a ridge of moisture aft of the fuel cell and ahead of the aileron on the left wing. We aborted the takeoff and proceeded the ramp for future inspection.

Title: B350 CREW ABORTED TKOF AFTER THE CAPT DETECTED WING CONTAMINATION AFTER EXTENSIVE DELAYS IN HVY SNOW.
Narrative: AT APPROX XA50 AM, IN HVY SNOW, WE ABORTED A TKOF DUE TO CONTAMINATION ON THE WING. WE HAD AN EXTENDED TAXI TIME PLUS A HOLD-SHORT TIME TO LET ANOTHER ACFT DEPART. BY THE TIME WE WERE ON THE RWY, THERE WAS SNOW ON THE WING. DURING THE TKOF ROLL, IT WAS APPARENT THAT THE WING STILL HAD A LITTLE SNOW ON IT. WE ABORTED THE TKOF DUE TO POSSIBLE CONTAMINATION, AND WENT BACK TO THE GATE TO MAKE SURE WE WERE DEICED AND HAD A CLEAN AIRFRAME. SUPPLEMENTAL INFO FROM ACN 570098: A TKOF WAS ABORTED DUE TO POSSIBLE CONTAMINATION ON THE WING SURFACE. UPON FINAL INSPECTION OF THE WINGS BEFORE TKOF, THE WINGS APPEARED WET WITH WATER DROPLETS AND THE WINGLETS HAD A DUSTING OF SNOW. ON THE TKOF ROLL AND AT APPROX 60 KTS, I NOTICED WHAT APPEARED TO BE A RIDGE OF MOISTURE AFT OF THE FUEL CELL AND AHEAD OF THE AILERON ON THE L WING. WE ABORTED THE TKOF AND PROCEEDED THE RAMP FOR FUTURE INSPECTION.
