Relief from operational limitations on Jabiru-powered aircraft
Owners and operators of aircraft powered by Jabiru engines may return to normal operations by meeting a number of conditions set out in a new CASA direction.
In late 2014 CASA first introduced a set of precautionary operational limitations on Jabiru-powered aircraft in response to a high rate of engine failures and malfunctions over a number of years. The limitations included restricting operations to daytime VFR flight, limiting flights over populous areas, requiring passengers to acknowledge their acceptance of the risk associated with flying in affected aircraft and requiring flying instructors to ensure students flying solo in Jabiru-powered aircraft were up-to-date with their engine-failure training.
Relief from these limitations follows on from CASA’s collaborative work with Jabiru to identify steps that could be taken to mitigate the risk of in-flight shut downs and related engine malfunctions until clear causal factors, and appropriate responsive solutions, could be identified. Recreational Aviation Australia assisted in this effort. Different maintenance-related actions are called up for engines falling within each of the three groups identified in the direction, and depending on whether the aircraft is, or has been, engaged in flight training operations. If the owners and operators of relevant Jabiru-powered aircraft do not undertake the actions applicable to their aircraft, the operating limitations will continue to apply to their aircraft.
The new direction and conditions took effect on 1 July 2016.
