What happened
During a visual approach to a runway measuring 12,000 feet in length and 150 feet in width, the flight crew received an aural wind shear alert at approximately 700-800 feet above ground level. There were no secondary system indications associated with this alert. The approach continued uneventfully, becoming stabilized by 500 feet above ground level under visual meteorological conditions.
The aircraft touched down on the runway centerline at the 10,000-foot runway marker. Shortly after the nose wheel made contact with the surface, the airplane drifted to the right. The crew attempted to correct this drift by applying full left rudder, left aileron, and differential braking, but these inputs failed to stabilize the aircraft. Before departing the runway surface, the crew applied both brakes to reduce speed during the excursion. The flight crew was able to maneuver the aircraft back onto the runway, where it eventually came to rest on the left side of the runway. No injuries were reported.
The investigation
An examination of the aircraft by both the manufacturer and the operator revealed no mechanical anomalies that contributed to the accident. Following manufacturer recommendations, the nose landing gear assembly was removed and replaced. Subsequent functional check flights were completed without any noted anomalies.
