General Electric’s proposed purchase of Honeywell International has been blocked by European Union regulators. As a result, the 146’s ALF502, the RJ’s LF507, and the RJX’s AS977 engines will remain Honeywell products rather than taking on the GE brand. It would not have been the first brandname change for the family’s engines, which have already gone from the Avco Lycoming, then Textron Lycoming, then AlliedSignal, then Honeywell brands. Excessive concentration in the market for regional jet engines was one of the concerns cited by the EU. GE’s CF34 engine powers the Canadair Regional Jet, and has been selected to power the Fairchild Dornier 728JET family and the Embraer ERJ-170 family.
