What engine does a jabiru have?
The Jabiru 3300 is a lightweight four-stroke, horizontally opposed flat-six air-cooled aircraft engine produced by Jabiru Aircraft. The engines are direct drive and fitted with alternators, silencers, vacuum pump drives and dual ignition systems as standard. Problems with Jabiru engines include failures of through bolts, flywheel bolts and valve train assemblies, as well as cylinder cracking.
How much horsepower does a Jabiru 3300 engine have?
The J3300 is a 120HP aircraft engine manufactured by Jabiru in Australia. It is a direct drive, flat six boxer layout. The Jabiru 3300 is a lightweight four-stroke, horizontally opposed flat-six air-cooled aircraft engine produced by Jabiru Aircraft. The engines are direct drive and fitted with alternators, silencers, vacuum pump drives and dual ignition systems as standard.
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. Jabiru’s engineering team has identified an issue with specific batches of crankshafts that could, in certain circumstances, lead to crankshaft failure. This issue was discovered after a small number of in-service engine failures occurred. Importantly, no injuries have resulted from these incidents.
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. Owners and operators of light aircraft with Jabiru engines that have 3/8 inch diameter through-bolt configurations need to be aware of the continued elevated risk of a through-bolt failure leading to an engine failure or malfunction in flight.
