What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) The aircraft was being taxied under power in conjunction with ramp snow removal operations. As the aircraft was being taxied, the speed of which was described by the pilot as a "fast taxi", the aircraft encountered a section of the surface that was contaminated with ice. The aircraft tires lost traction with the surface resulting in the aircraft sliding off of the taxi surface into an adjacent snow berm. The right wing contacted the snow berm resulting in substantial damage.
