- Date: June 30, 1991
- Aircraft: Beechcraft 65 Queen Air
- Location: Pioneer, California, United States
- Fatalities: 6
- Phase of flight: En route
- Cause: The pilot's improper emergency procedures in shutting down the good left engine. Contributing factors were an exhaust valve failure in the right engine following improper installation by maintenance personnel, and the pilot's limited familiarity with the aircraft.
After a partial power loss in the right engine on a private flight from Modesto to South Lake Tahoe, the pilot shut down the left engine as well. The Queen Air then rolled, inverted and entered a spin, colliding with trees in mountainous terrain. All six occupants were killed.
