Engine Parts Repair Technologies
Don't scrap what can be fixed
We focus on developing new repair techniques. Today numerous repairs which were originally invented by our engineers are now recommended as standard procedures in the manuals of engine manufacturers. A good example for this is our Advanced Recontouring Process (ARP) for worn compressor blades. The software-controlled process creates a completely new leading-edge profile with optimum aerodynamic characteristics. "Making a good engine even better" is not just empty words for us. Our innovative techniques not only increase the service life of your engine, but help to reduce the fuel consumption and to protect our environment as well.
EPAR: Longer life and less shop visits
Put to good use
By using EPAR repair technologies, you can reduce costs considerably and benefit from the increased service life of your components. Besides avoiding scrap and expensive new parts purchase, EPAR allows for an optimization of both the total costs and the on-wing time of your engines with a longer mean time between shop visits. We offer nearly 100 percent in-house repair capability. And as we have a strong interest in utilizing dismantled parts, we have set up a dedicated engine teardown shop with BizJet International in the US.

Big savings with bulkhead panel repairs
With two straightforward repair processes for the CFM56-5C engine's bulkhead panel, we offer a dependable and economic solution. The fire shield bulkhead panels of a turbofan isolate the thermal area from adjacent structural parts and protect the engine in case of flashbacks. During incoming inspections, we frequently observed major wear above the limit on the support plates of the low-pressure turbine cooling manifold tube support. The Engine Shop Manual does not offer a repair solution – the part would normally have to be scrapped and replaced.
We havedeveloped a repair process that comprises replacing the worn support plates with re-engineered locally manufactured parts. Form, fit and function of the new support plates are identical with the exchanged parts. Another fault regularly found was severe damage to the seal retaining lip. We perform a weld repair to restore the worn part to original drawing specifications. Both repairs are highly efficient and avoid the necessity to scrap parts.
