Narrative:
While enroute it appeared that the anti-icing system didn't work properly. This forced the crew to divert to San Manuel. Because the airspeed indicators malfunctioned during the landing phase, the aircraft landed with a much too high speed. The reversers didn't operate, so the aircraft overran the runway and ended up in a ditch. The gear collapsed and the aircraft caught fire. The co-pilot was not qualified to act as a co-pilot on this flight.
PROBABLE CAUSE:
"Wrong runway .. selected .. pilot in command
Airspeed .. excessive .. pilot in command
Proper touchdown point .. not attained .. pilot in command
Operation with known deficiencies in equipment .. performed .. pilot in command
Judgment .. poor .. pilot in command
CONTRIBUTING FACTORS
Weather condition .. tailwind
Landing gear,main gear .. overload
Pressure induced by others .. pilot in command
Propeller system/accessories,reversing system .. failure,partial
Anti-ice/deice system,windshield .. inoperative
Precautionary landing .. premature .. pilot in command
Procedures/directives .. not followed .. pilot in command"
