In years past, the top business jet OEM in AIN’s annual product support survey tended to lead its nearest competitor by just a few hundredths of a point, but Bombardier decisively took the top spot this year with a nearly one-third-point lead, averaging an overall 8.37 score. The Montreal-headquartered business jet manufacturer also dominated in six of the 10 categories rated by AIN readers in the survey—cost-per-hour programs, parts availability, cost of parts, AOG response, warranty fulfillment, and technical reps—and placed second in all but one (authorized service centers) of the others.

Dassault, whose Falcon line improved on its score year over year, ended up in second place among business jet manufacturers in this year’s survey, leapfrogging rivals Gulfstream and Embraer with an overall score of 8.08. Savannah-based Gulfstream, which tallied an average score of 8.05 in this year’s survey, led in the overall aircraft reliability category with a 9.01, and its factory-­owned service centers topped that category as well (8.18).
