- Date: February 10, 1994
- Aircraft: Cessna 421C Golden Eagle III
- Location: San Antonio, Texas, United States
- Fatalities: 2
- Phase of flight: Approach and landing
- Cause: Refueling with jet fuel caused preignition and detonation, leading to piston failures in both engines; the fuel truck lacked the restrictive nozzle needed for the aircraft's fuel tank restrictors.
A Cessna 421C air ambulance departing San Antonio reported a problem and tried to return. Both engines produced black smoke and the aircraft struck a tree half a mile from the runway threshold. Fuel samples were about half jet fuel, which had been put in during refueling, and both engines suffered piston failures.
