    COMPANY PHILOSOPHY

    3/31

    Currently, a fuel leak typically takes 36 to 72 hours to be

    repaired... (sometimes, a lot longer than that)!

    AEROWINGs new technologies canreduce this time to 6 to 12 hours,

    with very good reliability

    TYPICAL EXAMPLE: FUEL LEAK

  • 7/21/2019 Aircraft Tank Repair

    Most Time Consuming Tasks when Repairing a Fuel Leak:

    1.) Finding the leak source inside the tank

    2.) De-sealing (removing) the faulty sealant

    3.) Cure time for new sealant

    4.) Quality control of the repair (Soak Check) -In the event of a re-leak, the clock starts again from zero!

    THE FOUR MOST TIME CONSUMING TASKS

    5/31

    SAME METHODS SINCE 1940s

    Most Common Methods Currently Used for Finding Fuel Leaks:

    Blow Back Method - High pressure air applied from the

    outside leak point and searching for bubbles inside the tank

    (admitted by Boeing to be around 60% accurate)

    Dye Method Using low viscosity penetrating fluid

    It is the lightest and smallest inert gas molecule.

    It easily flows through very small leak paths.

    It permits non destructive and dynamic testing.

    HELIUM IS A VERY LIGHT INERT GAS

    NEW TECHNOLOGY - HELIUM LEAK DETECTION: WHY HELIUM?

  • 7/21/2019 Aircraft Tank Repair

    7/31

    Helium is non toxic and non reactive.

    Helium is non hazardous.

    Helium is non flammable, nor explosive.

    HELIUM IS SAFE

    NEW TECHNOLOGY

    AEROWING - Helium Leak Detection -

    Proven by Boeing and Airbus to be 95 98% accurate inlocating leaks within the tank

    Important Features: Portable, Intrinsically Safe, Accurate,Selectable Sensitivity, Auto Zero Feature

    Able to be used for finding leaks in other aircraft systems(Pitot Static System, Oxygen System, EnvironmentalControl System, Engine Bleed Air System, etc.)

    HELIUM METHOD ADVANTAGESHELIUM METHOD ADVANTAGES

    Helium is 1000 times more sensitive than bubble.

    Helium allows dry testing, better for health and safety.

    Helium allows dry quality control for rapid repair cycle and

    less expensive testing.

    RAPID DESEALINGRAPID DESEALING

    DAYS TO REMOVE SEALANT:

    Current method - scrape sealant by hand using pieces of

    plastic or aluminum fashioned as cutting tools

    Existing sealant can be 2-3 inches thick with multiple layers

    Difficult areas to work inside (and outside) the tank
