What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) During takeoff roll on runway 04, aircraft encountered ice spot on runway. Aircraft began sliding to the right after accelerating to approx. 60-70 knots airspeed. As the pilot began to abort the takeoff the aircraft started sliding to the left. It exited the left side of the runway approx. 1000 feet from the departure end of runway 04. As it was exiting the runway it turned approx. 120 degrees nose left. It departed the runway an estimated speed of knots coming to rest in the snow about 6-10 feet off the runway. The crew had landed on this runway about 45 minutes earlier in a different aircraft and encountered some wet spots on the runway (also a NOTAM for this was in effect). By the time they departed the wet spots had time to freeze as the temperature dropped after the sun set.
