Product Support Survey 2010 Part 3: Engines

Among turbofan manufacturers, Williams International remains tops with AIN readers for the support it provides to operators. Rolls-Royce, combined into one listing this year for the first time instead of being separated into R-R and R-R Deutschland, takes second place and, by barely a gnat’s whisker, bumps Pratt & Whitney Canada to third place. Honeywell takes fourth place, followed by GE, CFE and CFM, but the score spread from first (8.09) to last place (7.32) is not great (see rating scale on page 53), suggesting that the efforts of all the manufacturers are succeeding to levels that do not vary wildly.
