CC138803 - Twin Otter

CC138803 Twin-Otter - From the investigator

The aircraft touched down on a smooth area of sea ice, but then bounced into the air after hitting an ice ridge perpendicular to the aircraft’s heading. The aircraft impacted the base of a larger ice ridge once it settled back onto the sea ice. The nose landing gear collapsed and the aircraft came to a stop shortly thereafter. The aircraft was very seriously damaged.
