Factors associated with the accident were the gusting wind and the icy runway. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - on ground/water, takeoff - roll/run - weather condition - gusts (contributing factor) - weather condition - crosswind (contributing factor) - compensation for wind conditions - inadequate, pilot in command (cause) - terrain condition - runway - terrain condition - icy (contributing factor) - On ground/water encounter with terrain/water, takeoff - roll/run - terrain condition - snow covered ## Analysis The airline transport certificated pilot of the Title 14, CFR Part 135 flight was taking off on runway 33, when a gust of wind blew the airplane to the left edge of the runway where it encountered a snow berm. The pilot reported the runway was ice-covered, and the wind was from 060 degrees at 20 knots, with gusts to 25 knots. The airplane exited the runway, the nose gear collapsed, and the left wing struck the ground. According to the director of operations for the operator, there were no known mechanical anomalies with the airplane prior to the accident. He said the airplane sustained damage to the left wing, nose gear and propeller during the accident. ## Factual narrative The airline transport certificated pilot of the Title 14, CFR Part 135 flight was taking off on runway 33, when a gust of wind blew the airplane to the left edge of the runway where it encountered a snow berm.
