Accident occurred Friday, February 24, 2017 in Waukesha, WI
Probable Cause Approval Date: 04/04/2017
Aircraft: CESSNA 340A, registration: N255BC
Injuries: 1 Uninjured.
NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.
Before the positioning flight, the airline transport pilot monitored the weather and noticed the weather conditions were deteriorating near the time of the planned departure. The weather conditions included low visibility, freezing drizzle, and mist. In an effort to reduce the time in the deteriorating weather conditions, the pilot performed some before takeoff checks while the airplane was in the hangar. During the pilot’s “haste” to preflight and take off, she inadvertently selected the wrong switch for windshield heat. While on the instrument approach to the runway in night conditions, the pilot had no forward visibility due to 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. The pilot then activated the windshield heat switch and enough ice had melted for the pilot to conduct another approach. During the approach, the pilot increased the airspeed due to “carrying a lot of ice.” On short final approach, the airplane descended below the glidepath due to the ice accumulation. Subsequently, the airplane contacted the terrain short of the runway and then “skipped” onto the runway. The airplane came to rest upright and off the runway surface. 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.
The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
The pilot’s decision to fly in in conditions conducive to structural icing and her subsequent failure to maintain airplane control during the instrument approach.

WAUKESHA COUNTY -- Authorities tell FOX6 News a plane slid off the runway at Waukesha County Airport/Crites Field Friday evening, February 24th.
The Waukesha County Sheriff's Office says it happened around 6:48 p.m.
Upon arrival, the sheriff's office observed a Cessna 340A with substantial damage on the left side.
According to Crites Field Airport Director, Kurt Stanich, the plane landed short of the runway, which caused the plane to then skid off the runway.
The pilot and sole occupant, a 55-year-old woman from Sun Prairie, was able to walk away from the incident with no injuries.
The incident remains under investigation by the FAA and the Waukesha County Sheriff's Office.
The airport will remain closed until the plane can be removed and the airfield checked for debris.
No other details have been released.
