The Asiana Boeing 777-200ER which crashed at San Francisco International airport was powered by Pratt and Whitney PW4090 series engines.
Three engine manufacturers have offered power plants for the Boeing 777. Pratt and Whitney offered the PW4000 series. Rolls Royce offered its Trent 800 and General Electric offered its GE90 series.
The infographic below shows the share of market each manufacturer has on the 1,113 Boeing 777s delivered till date.
Since the last few years, GE90-115B and GE90-110B are the exclusive engine series for the currently manufactured 777 variants – the 777-300ER, 777-200LR, and the 777F freighter. So eventually it will have a 100% share of the market. Even on the upcoming 777X project, GE is expected to remain the sole source supplier with a new upgraded engine.
