For reasons that are not clear, every engine manufacturer scored fewer points in this year’s survey than in last year’s, something that did not happen with the airframers and avionics makers. Williams International retains the number-one spot among turbofans for the quality of product support it provides our readers (its customers), and Rolls-Royce remains in the number-two spot. Pratt & Whitney Canada makes a big stride into third place (from fifth last year). Rolls-Royce Deutschland drops to fourth from third, its score falling the most at -5.47 percent; Honeywell climbs to fifth from sixth; CFE drops to sixth from fourth; and GE remains at the bottom in seventh.
Among engine models, the Williams FJ44 achieves the top average score this year, moving up from last year’s second place. Last year’s top-scoring Honeywell HTF7000 moves into fifth place this year, scoring nearly 8 percent less this year. All of Pratt & Whitney Canada’s turbofans move up in the model rankings this year, and the company’s PW500 series is the sole engine industry-wide to score more points this year than last, an improvement that elevates the engine to sixth place this year from 11th last year.
