Innovative repair of CF6-80C2 TR core bondment 

To meet every individule demand of our customer

Lufthansa Technik Shenzhen has introduced a new Airframe related components (ARC) repair procedure.

Due to deterioration by aging, CF6 fan reversers often suffered from wire mesh peel off. This caused a premature removal in order to replace the wire mesh. Many operators complained about this additional cost. That is why the OEM decided to introduce a new designed perforated skin for the core.

Several operators let their service provider install such new core bondments in order to improve reliability and cost in the long run. New parts, of course, are quite expensive. In addition, the leadtime of such parts was long because of the high demand.

With the new in-house repair procedure, the core bondment gets the new perforated skin which does not need the wire mesh. Result: wire mesh delamination is not possible, therefore no premature removals will happen for this reason and that means less cost. Compared to the OEM's list price, 40 percent costs can be saved by using Lufthansa Technik's upgrade instead of using a new part.

"As the only MRO provider who has this capability, Lufthansa Technik provides its customers with this cost- and time-saving solution," said Rick Xu, Chief Engineer of Lufthansa Technik Shenzhen.
