AIN readers rank GE as the top provider of product support among turbofan makers this year, a distinction the company earned once previously in the past 10 years when it shared the top spot with Rolls-Royce in 2012. Williams has been king of the hill for eight of the past 10 years (sharing that honor once, with Rolls, in 2014). Rolls-Royce takes third place among turbofan makers this year, followed by Honeywell, Pratt & Whitney Canada and CFE. It should be noted, however, that the top four placers this year are each separated by only one tenth of a point.
By a much wider margin, Honeywell takes the top spot among manufacturers of turboprops and turboshafts, outscoring second- and third-place finisher Pratt & Whitney Canada by almost a full point. Safran Helicopter Engines (née Turbomeca) takes fourth place. Rolls-Royce (manufacturer of the ubiquitous 250 helicopter turboshaft) did not receive enough responses to qualify for inclusion.
