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. The engine is used to power homebuilt and ultralight aircraft. HistoryIn November 2014 the Australian Civil Aviation Safety Authority proposed restricting all Jabiru-powered aircraft to day-visual flight rules only, without passengers or solo students and within gliding distance of a safe place to land due to the engine line's safety record. This was in response to 46 reports of engine failure in flight. In flight failure modes included, but were not limited to: fuel starvation; valve/port collapse & breakage of critical bolts.[1][2][3] Both the manufacturer and Recreational Aviation Australia opposed the restrictions as unnecessary and unwarranted.[4] The final rule adopted somewhat softened the restrictions, allowing the carriage of passengers and students, but requiring them to sign an acknowledgement of risk before flying and restricting equipped aircraft to day VFR flight and within gliding distance of a safe place to land.[5] A subsequent tear-down of one engine by CASA resulted in recommendations in June 2016 for further easing of the restrictions.[6] Applications{{columns-list|colwidth=30em|
