What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) Pilot made the approach to the Toksook Bay Airport due to wind conditions with 10-degree flaps, due to what appeared to be about 20-25 KTS crosswind. After touchdown, on what the pilot expected was good runway conditions due to that mornings report by the village agent only said "good". The touchdown was normal and after about a 400 ft roll-out, he put the propellers into reverse to further slow down to stop and at this point a violent gust of wind caused the aircraft to quickly yaw to the left and began to slide to the right and off the runway. This is when he first realized the runway was covered with a clear coat of ice. The aircraft slid perpendicular to the runway for a short distance, then the right wheel caught a snow berm and the aircraft quickly swung to the right, causing the nose wheel to shear off. The aircraft also rolled enough to the right to have the right propeller strikd the snow berm, and right wing tip to brush the ground. The aircraft came to a stop with both main wheels on the ground and the crew evacuated the passengers through the normal exit. No injuries were sustained by the crew or the passengers. The pilot had landed there the previous day and the runway was bare gravel.

THIS IS WHEN HE FIRST REALIZED THE RUNWAY WAS COVERED WITH A CLEAR COAT OF ICE. THE AIRCRAFT SLID PERPENDICULAR TO THE RUNWAY FOR A SHORT DISTANCE, THEN THE RIGHT WHEEL CAUGHT A SNOW BERM AND THE AIRCRAFT QUICKLY SWUNG TO THE RIGHT, CAUSING THE NOSE WHEEL TO SHEAR OFF. THE AIRCRAFT ALSO ROLLED ENOUGH TO THE RIGHT TO HAVE THE RIGHT PROPELLER STRIKD THE SNOW BERM, AND RIGHT WING TIP TO BRUSH THE GROUND. THE AIRCRAFT CAME TO A STOP WITH BOTH MAIN WHEELS ON THE GROUND AND THE CREW EVACUATED THE PASSENGERS THROUGH THE NORMAL EXIT. NO INJURIES WERE SUSTAINED BY THE CREW OR THE PASSENGERS.
