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

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

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?

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
