Overhaul

Overhauling your engine

Things wear out, things deteriorate and things break. If this is true in any industry, it is even more true in aviation. Aircraft need constant repair, inspection, and upkeep whether they get used or not. In fact, it’s a common theory that aircraft have more problems and need more repair when they are not used regularly.

Airframes and aircraft engines are carefully inspected, adjusted and tested at each scheduled inspection. And often, a number of problems are discovered and repaired during these events.

When we overhaul an engine, we do a complete disassembly of the engine. We thoroughly inspect the engine, repair it as necessary, reassemble, test, and approve it for return to service within the fits and limits specified by the manufacturer’s overhaul data.

 

Cleaning

Soda Blasting

AERO Assist uses soda blasting to clean the engines and engine parts. It is a new paint stripping and cleaning technology that propels a bicarbonate-of-soda media (via compressed air) onto the area to be cleaned. This process removes paint and contaminate without harming the underlying surface. Blast material is specially formulated sodium bicarbonate (baking soda). Soda blasting can clean all types of surfaces. Our specially designed soda is delivered to a surface by means of low pressure compressed air at high velocity. The soft, sharp granules of the soda are used to clean, degrease and remove paint and dirt from your engine casing without damage or residue (including bearings and seals!). Many other methods such as water blasting sand blasting or chemical cleaning are too abrasive to the surface and are not environmentally friendly. Soda blasting uses blasting media that is 100% biodegradable, non toxic, non hazardous, non sparking, non flammable, water soluble, odorless, non corrosive and mould resistant.

Ultrasonic Cleaning

Ultrasonic Cleaning Systems are based on high-frequency sound waves, which are transmitted through a flowing liquid where the piece to be clean is submerged. Treatment takes between 10 and 45 minutes, but no operator presence is needed.

Ultrasonic waves produce cavitation, in which millions of gas bubbles are generated into the liquid, and then compressed until they implode, releasing huge amounts of energy. This energy hits the dirt,grease or carbondust over the surface of the objects to be cleaned, removing it without damaging the piece.

The result is a micro-brushing phenomenon which cleans the pieces treated. As gas bubbles are only 1 µm, they penetrate into every orifice, making Ultrasonic Cleaning best system for highly complex components in any kind of material (cast iron, steel, aluminium, copper, bross, titanium, bronze, some plastics & rubbers, …).
