What are the disadvantages of a jabiru?
Problems with Jabiru engines include failures of through bolts, flywheel bolts and valve train assemblies, as well as cylinder cracking. Engine through-bolt failures were the most commonly reported failure mechanism in Jabiru powered aircraft with 21 through-bolt fractures reported between 2009 and 2014.The Jabiru are a very capable robust and solid platform; easily serviced and widely supported; and they get up and move when needed. Its a good all rounder aircraft.Problems with Jabiru engines include failures of through bolts, flywheel bolts and valve train assemblies, as well as cylinder cracking.
Are Jabiru engines reliable?
Jabiru engines have a 300% higher rate of failure than Rotax, which itself has a 30% higher rate of failure than Lycoming and Continental engines. 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.
