NTSB narrative

While climbing after takeoff, the former Czech military jet trainer experienced a total loss of engine power and struck pine trees in a wooded area about 1 mile southwest of the airport. Subsequent examination of the airplane's fuel system revealed fuel that drained from the fuel filter was contaminated with black sediment, and appeared "extremely cloudy." Additionally, the fuel filter element was contaminated and restricted the flow of fuel to the engine. The pilot purchased the airplane about 1 year prior to the accident. The maintenance records were not located. The pilot fueled the airplane from a tank on the back of a pickup truck. Review of fuel receipts revealed that the day prior to the accident, the pilot purchased about 138 gallons of "kerosene," 6 gallons of "off road diesel," and 27 gallons of "diesel" fuel. Review of a preflight inspection checklist for the airplane revealed that it included discharging "2 liters" of fuel from the fuel filter drain to check for contamination.

Probable cause

A total loss of engine power due to fuel starvation as a result of a clogged fuel filter that was not identified due to the pilot's inadequate preflight inspection.

  • Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
  • Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
  • The date is the local date, which is the same as the UTC date the NTSB stores.
