Product Support Survey 2011 Part 3: Engines

The top three spots for product support among turbofan builders remain unchanged this year from last year’s rankings: Williams retains the number-one position, followed by Rolls-Royce and Pratt & Whitney Canada, separated this year by one hundredth of a point. Last year Honeywell beat GE by just one hundredth of a point; this year, the two companies tied for fourth with 7.63. CFE brings up the rear, and CFM did not receive enough responses to qualify.

Among turboprop manufacturers, Pratt & Whitney Canada keeps the top spot; Honeywell moves up to second place this year from third place last year, displacing Rolls-Royce to third place this year from second place last year. Turbomeca remains last in the rankings.
