Aircraft Accident/Incident Report

NTSB Narrative Summary Released at Completion of Accident
The business jet touched down near the threshold of the 5,500-foot-long, asphalt runway, at an airspeed of 100 knots. The pilot reported the braking effectiveness as "adequate" initially, and as the airplane approached the mid-field position of the runway, the braking effectiveness decreased until it was "near nil," and the airplane was no longer decelerating. The pilot maneuvered the airplane off the left side of the runway to gain traction from the adjacent grass area, during which it impacted a drainage ditch, resulting in substantial damage to the airplane. The area off the end of the runway was an open field with no obstructions. Examination of the runway revealed it was covered in black ice, with a thin layer of water. The weather reported at the time of the accident included 5 miles visibility with light snow. An employee of the fixed base operator (FBO) at the airport reported that at the time of the accident the main ramp and taxiways were coated with 1/4 to 1/2 inch of ice from earlier precipitation. The airport manager reported that, about 1.5 hours prior to the accident, when he was leaving for the day, the forecast was for little or no precipitation and the temperature was expected to increase. However, the temperature decreased instead, resulting in the formation of ice on the runway. The airport manager reported at the time of the accident the north end of runway 17 was dry; however, the south end of runway 17 had "some ice on it." The normal procedure for the airport to treat ice on the runway was to issue a NOTAM to close the runway and deploy their ice melt product. Then, they would cancel the NOTAM and issue another one stating that ice is present on the runway. Because the temperature was forecast to rise and not fall, the airport did not use any ice melt product on the runway. Additionally the airport personnel did not have the equipment or training to issue braking action reports, nor was it required. The pilot reported no pre-impact mechanical deficiencies with the airplane.
NTSB Probable Cause Narrative
The airplane's runway excursion during landing roll following an encounter with ice. Contributing to the accident was the ice-covered runway, and the airport personnel's lack of knowledge regarding the runway condition.
