Smoke System Inspection Checklist

Your Smoke System Inspection Checklist

We recommend doing a thorough inspection of your smoke system every year or every 50 hours of engine run-time to keep it in great shape. While Smoking Airplanes smoke systems are built to last, proactive maintenance will ensure beautiful smoke trails for years and years.

Before you start your inspection, pressurize the smoke system by closing and opening the oil mixture valve (or oil cutoff valve for jets).

Inspect the Oil Pump

  • Look out for leaks, frayed wire or cracks.
  • Make sure the screws on the oil pump are tight.

Clean the Inline Oil Filter

  • Loosen both hose clamps and remove the filter from the hose.
  • Use two pairs of pliers or lightly clamp the long end of the filter in a vise and unscrew with pliers.
  • Remove the spring and the screen.
  • Blow compressed air (about 20 psi) to clean the screen or carefully wash with soapy water.
  • Reassemble (the filter screen dome faces up) and don’t over tighten.

Inspect the Oil Tank

  • Check each component of the tank for leaks, cracks, or damage.
  • Make sure the filler cap seal is secure.

Inspect the OIl Tank Brackets

  • Check the tightness of the brackets connected to the airframe.
  • Then check the brackets on the oil tank.

Check the Vent System

  • Look over the vent system and its parts for any blocks.
  • Inspect the overall condition of the vent system.

Look Over the Black Pressure Hose

  • Make sure it doesn’t have any leaks or cracks.
  • Plus check that the hose clamps are secure and the tie-wrap hangers are in place.

Inspect the Wiring

  • Make sure the wiring is in good condition.
  • Check for any chafing, looseness, or potential short circuits.

Inspect the Injector and Stainless Steel Braided Hose(s)

  • Check for wear or blockage.
  • Inspect the tightness of the clamps.
  • Look out for weld cracking.

Ensure safety wire is in place and secure.
