Redding - Butte

On August 11, 2010 at 08:55 AM, Redding - Butte experienced a crash involving Rockwell Aero Commander 500, operated by Frank N. Vessels, with the event recorded near Mt Steens Oregon.

The flight was categorized as private and the reported phase was flight at a mountains crash site.

2 people were known to be on board, 2 fatalities were recorded, 0 survivors were identified or estimated. This corresponds to an estimated fatality rate of 100.0%.

Crew on board: 1, crew fatalities: 1, passengers on board: 1, passenger fatalities: 1, other fatalities: 0.

The listed crash cause is human factor. The evening prior to the accident, the pilot acquired a computer generated text weather briefing. On the day of the accident, the pilot acquired another computer generated text weather briefing, and then contacted the Flight Service Station (FSS) for an interactive telephonic weather briefing. The information provided in all three briefings indicated that a flight on a direct route between the pilot's point of departure and his planned destination would take him through an area of forecast rain showers, thunderstorms, and cloud tops significantly higher than his intended en route altitude. Although the FSS briefer recommended an alternate route, for which he provided weather information, after departure the pilot flew directly toward his destination airport. While en route, the pilot, who was not instrument rated, encountered instrument meteorological conditions, within which there was an 80 percent probability of icing. After entering the area of instrument meteorological conditions, the airplane was seen exiting the bottom of an overcast cloud layer with a significant portion of its left wing missing. It then made a high velocity steep descent into the terrain. A postaccident inspection of the airplane's structure did not find any evidence of an anomaly that would contribute to the separation of the wing structure, and it is most likely that the wing section separated as a result of the airplane exceeding its structural limitations after the pilot lost control in the instrument meteorological conditions.

Aircraft reference details include registration N500FV, MSN 500-1248-73, year of manufacture 1962.

Geospatial coordinates for this crash are approximately 44.9572°, -123.0684°.
