The Package C variant forms the largest part of the Trent 1000 fleet, powering a total of 170 aircraft out of 300 aircraft in service.Operators of Trent-powered Boeing 787s have encountered a number of in-service issues with the engine, leading to operational restrictions and grounding of aircraft in some cases. The current redesign addresses the IP compressor rotor blade, some of which had experienced cracking due to vibration.
