A second performance improvement package (PIP2) for GE Aviation's GEnx-1B engine will enter into service in the third quarter of 2013.
PIP2 has completed 70% of its certification testing, including a period on the testbed flying, says Chuck Nugent, general manager of the GEnx programme.
The engine's first PIP (PIP1) is in-service with Japan Airlines (JAL), who took delivery of the first Boeing 787 with the improved engine in February, and is performing beyond expectations, says Nugent.
As of 6 July, eight GEnx-1B engines are in service on JAL's 787s. They have accumulated a total of 5,600 hours in 1,150 cycles, says GE. Another variant of the engine, the GEnx-2B, powers the Boeing 747-8I and 88 of the latter engine are in service, accumulating 126,000 hours over 27,000 cycles.
GE Aviation expects to deliver 3,400 engines in 2012, of which 2,400 will be commercial types, 200 more than in 2011.
The engine manufacturer forecasts a higher level of production in 2013, and anticipates handing over 2,600 commercial engines and a further 1,000 military powerplants.
GE Aviation chief executive David Joyce also expressed confidence in the manufacturer's proposal for the GE9X engine, which it hopes will power the proposed Boeing 777X. GE will compete against Pratt & Whitney and Rolls-Royce, which have also responded to a request for information issued by Boeing in 2011.
Joyce points out GE's incumbency on the 777-200LR and -300ER, as well as its commitment to the GEnx, which puts the engine manufacturer in a good position to deliver "the best engine for the 777X".
GE's CF6 engine, the predecessor of the GEnx, will remain in production through 2025, adds Joyce.
