Avio's civil engines division grew revenues by 24% in 2012.
The Italian parts maker attributes the result to "the success of the GEnx engine" - which powers the Boeing 787 and 747-8 - and deliveries of GE's GE90 and CF6-80 powerlants and the CFM International CFM56.
The civil engines division represents the "primary activity" of the Avio group, which is in the process of being acquired by GE.
Overall, group revenues climbed 16% to €2.35 billion ($3.06 billion) last year. Earnings, at €431 million, were up 12%.
In December 2012, GE agreed to buy Avio's aviation business for $4.3 billion. The Italian group's space business, which accounted for 12% of 2012 revenues, was not included in the deal, which pends governmental and regulatory approval.
With a product line that spans low-pressure turbine systems, accessory gearboxes, geared systems and combustors, Avio is a partner to Pratt & Whitney on the PW1500G geared turbofans for the Bombardier CSeries and Airbus A320neo; Safran, on the Sukhoi Superjet-powering SaM146; and Rolls-Royce on the Trent 900, used on Airbus A380s.
