Aircraft Accident/Incident Report
Mcalester, Oklahoma 74501
Friday, May 28, 1999 16:30 CDT
NTSB Narrative Summary Released at Completion of Accident
Shortly after takeoff, the airplane's left engine experienced a loss of power followed soon thereafter by a partial loss of power of the right engine. The pilot was unable to maintain altitude and made a forced landing in a field. The pilot added that he 'had to climb over power lines [and] stalled [the] aircraft.' The pilot stated that he had refueled the airplane with 90 gallons of fuel prior to his departure. He added that he had visually checked the fuel level prior to the departure; however, he did not sump the fuel tanks. Fuel samples that were taken from the airplane's left and right main fuel tanks contained a fluid on the bottom of each sample, which resembled water. A fuel sample taken from the refueling truck revealed no evidence of water contamination.
NTSB Probable Cause Narrative
The pilot inadvertently stalling the airplane while attempting to avoid power lines. Factors were the loss of power on both the left and right engines as a result of water contamination in the fuel system, the pilot's inadequate preflight procedures, and the lack of suitable terrain for the forced landing.
