Analysis

The pilot began taking off on a soft runway with a left quartering crosswind. He stated that he was unable to get enough speed on the soft mud for a safe takeoff. He cut the power to abort, but was unable to stop on the remaining runway. The plane continued off the end of the runway where the right main gear broke through thin ice and separated. The right wing was damaged and began burning where a navigation light had broken and caused a spark. A fire extinguisher was used to stop the flames, but the fire started again when the extinguisher was exhausted.
