What iS the failure rate of the Rotax 912 engine?
Rotax has more than 10,000 engines on the registry, but only about a third of those were the 912 and 914 four-cylinders we were interested in. Based on our data, the overall rotax failure rate is 1. And here a warning about small numbers; an accident or two can sway the rate substantially. The rotax 912 is a horizontally-opposed four-cylinder, naturally-aspirated, four-stroke aircraft engine with a reduction gearbox. It features liquid-cooled cylinder heads and air-cooled cylinders.
