Analysis

During takeoff on runway 14 with the winds from 310 deg at 17 knots, satisfactory acceleration occurred through 70 knots followed by a slowing rate of acceleration at 80 knots. The captain then reduced power and shortly thereafter felt the left main tires strike something and the aircraft began a left yaw. Attempts to regain directional control were unsuccessful an N5475M rolled off the east side of the runway and struck a snowbank. The crew shut down the engines and evacuated the passengers. The downwind takeoff was necessitated by visibility requirements for the departure.
