The AEL mark I fuel sample kit will accurately measure trace quantities of free water in which fuels?

• A. Gasoline or jet fuels
• B. Gasoline only
• C. Jet fuels only
• D. Diesel

Answer: (A)

Testing for free water in aviation fuels is about spotting tiny amounts of water that can settle out of fuel and cause engine problems or fuel-system icing. The AEL Mark I fuel sample kit is designed for the fuels commonly used in aviation that have similar behavior with water—gasoline (AVGAS) and jet fuels (kerosene-based fuels like Jet A or Jet A-1). Its chemistry and procedure are calibrated to detect trace free water in these fuels, giving a quick indication of contamination levels in either one. Diesel isn’t within the kit’s typical use, and its different properties can lead to inaccurate results with this test setup, so the kit isn’t intended for diesel. Therefore, the kit will accurately measure trace quantities of free water in gasoline or jet fuels.
