Aviation accident ANC05FA038

The fuel truck operator's improper refueling of a gasoline engine powered airplane with jet (turbine) fuel, and the pilot's inadequate preflight, which resulted in a loss of power in both engines and subsequent collision with trees. Factors associated with the accident were the unclear communications between the Spanish-speaking fuel truck operator and the English-speaking pilot, and the fuel truck operator's lack of familiarity with the accident airplane's fueling requirements. An additional factor was the absence of the required placards adjacent to the fuel filler caps indicating that only gasoline (av-gas) should be used.
