GNK Now Repairs CFM56-5B Fan Blades
GKN Aerospace has won approval from Snecma Services to repair and overhaul CFM56-5B fan blades.

GKN Aerospace has won approval from Snecma Services to repair and overhaul CFM56-5B fan blades. The authorization covers the restoration of the blades’ overall length and midspan shrouds. Critical to the engine’s efficient operation, the blade length and midspan shroud dimensions erode over time. GKN restores the blades by first welding and machining extensions and then applying a coating of high velocity oxy fuel tungsten carbide on the midspan shrouds.
