Between 2001 and 2006, there were a number of fatal single and
multi-engine aeroplane accidents that occurred, where the ATSB
found that engine power loss during or after takeoff preceded loss
of control. Those accidents involved different aircraft types, all
below 5,700 kg MTOW, and a variety of pilot experience. Partial
power loss, sometimes intermittent, featured in most of the single
engine power loss accidents. ATSB research papers were also
indicating an uncontrolled flight into terrain (UFIT)
While the ATSB investigated each accident individually, a safety issue investigation was initiated on 3 July 2006, to enable a broader look into what may assist the aviation industry to manage the risk of operating aircraft that don't have assured takeoff performance when an engine loses power (generally aircraft below 5,700 kg MTOW). Of particular interest was how pilots managed a partial engine power loss during or soon after takeoff in single engine aircraft.
The investigation found no significant safety issues that had not been addressed by developments and changes within the aviation industry since July 2006. As a result, the safety issues investigation was discontinued, however the ATSB has initiated an aviation research project to produce educational material for the aviation industry on this topic.
