Narrative Report
On September 26, 1982 at 01:08 PM, Hawthorne - San Luis Obispo experienced a crash involving Rockwell Aero Commander 520, operated by Donald Nelson, with the event recorded near Agoura Hills California.
The flight was categorized as executive/corporate/business and the reported phase was flight at a mountains crash site.
3 people were known to be on board, 3 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: 2, passenger fatalities: 2, other fatalities: 0.
The listed crash cause is human factor. During departure, the pilot climbed in IFR conditions to 6,000 feet. After leveling, a frequency change was made and he was cleared to 8,000 feet, which he acknowledged. About 2 minutes later, the controller radioed to the pilot that he was about 4 miles north of the airway, but there was no reply from the pilot. Shortly after that radar contact was lost and the plane crashed in mountainous terrain. Several residents in the area reported hearing extremely loud engine noises followed by complete silence. An investigation revealed that both wings had separated outboard of their respective engine nacelle assemblies. An examination of the fractures revealed the wings had separated from positive overload. The leading edges of both wings had ballooned upward, indicative of extreme airspeed. The empennage had separated in a yaw and from right torsional overload. Parts of the aircraft were found within a 1 mile arc, north of the main impact area. The pilot's recent instrument experience could not be verified. All three occupants were killed. Turbulence was forecasted below 8,000 feet.
Aircraft reference details include registration N2622B, MSN 520-134, year of manufacture 1954.
