On 8 March 2011, an Eastern Australia Airlines operated (the operator) Bombardier Inc. DHC-8-315 aircraft, registered VH-SBI, departed Melbourne, Victoria on a scheduled passenger service to Devonport, Tasmania.

On arrival at Devonport, a runway 24 area navigation global navigation satellite system (RNAV (GNSS)) approach was commenced. The crew did not become visual with the runway at the minima due to the prevailing weather conditions and a missed approach was conducted. The aircraft was climbed to 3,100 ft and a holding pattern conducted.

A second approach was commenced, during which time, the aircraft's speed decayed. The pilot in command (PIC) made two airspeed advisory calls and the copilot responded immediately by increasing power on each occasion. The two power applications failed to accelerate the aircraft and the crew observed the airspeed reduce to 107 kts. The PIC called assertively for more power to be applied and the copilot immediately responded by applying power. During the recovery, the aircraft's engines were over-torqued to 120% for about 2 seconds. The operator and engine manufacturer transient over-torque limits were not exceeded.

A second missed approach was conducted and the flight was diverted to Launceston, Tasmania where the aircraft landed without further incident.

In response to this incident, and a stickshaker warning event involving a Eastern Australian Airlines Bombardier Inc. DHC-8-315 aircraft on 1 March 2011 (ATSB investigation AO-2011-036), the operator issued a safety alert stating that the primary consideration for pilots is to maintain an awareness of the aircraft's speed, altitude and position; and controlling its flight path.
