The top three finishers are separated by just a tenth of a point each, as they were last year, but AIN readers again this year name GE as the best provider of support for the engines that power their business jets, in this case the CF34s found on 600-series Challengers and the Lineage 1000. GE slid slightly to an overall average score of 8.3 from its 8.4 first-place score last year. Rolls-Royce and Williams switched rankings this year, with R-R rising to second place (with the same 8.2 it scored last year) and Williams falling to third with a score of 8.1 (down from 8.3 last year). Pratt & Whitney Canada comes in fourth with 8.0 this year, up from 7.9 last year. Honeywell takes fifth place this year with 7.8, down from 8.1 last year, and CFE is last with 7.4, down 0.2 from 7.6 last year.
Among makers of turboprop engines, the rankings remain unchanged: Honeywell is still king of the hill with a score of 8.6 for support of the TPE331, down from 8.8 last year. Pratt & Whitney Canada keeps second place for PT6 support with 7.7, up slightly from last year’s 7.6. Safran Helicopter Engines (the former Turbomeca) is last with 7.0, down from 7.3 last year.
