Synopsis
Prior to a positioning flight, the pilot monitored weather conditions and observed deteriorating conditions, including low visibility, freezing drizzle, and mist near the planned departure time. To reduce time spent in the worsening weather, the pilot performed some before-takeoff checks while the airplane was in the hangar. During the preflight, the pilot inadvertently selected the wrong switch for windshield heat due to haste.
Flight Sequence
During an instrument approach to the runway in night conditions, the pilot had no forward visibility because of ice accumulation on the windshield. The pilot executed a missed approach and contacted an instructor pilot at the departure airport to confirm the location of the windshield heat switch. After activating the correct switch, enough ice melted for the pilot to conduct another approach. During the second approach, the pilot increased airspeed due to carrying a lot of ice. On short final approach, the airplane descended below the glide path due to ice accumulation. Subsequently, the airplane contacted the terrain short of the runway, then "skipped" onto the runway. The airplane came to rest upright and off the runway surface.
Damage and Findings
Examination of the airplane revealed substantial damage to the left wing. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.
