Final Report

Summary

At about 0730 Eastern Daylight-saving Time on the 14 December 2016, a Pelican Airlines British Aerospace Jetstream 32 aircraft, registered VH-OTQ, departed Newcastle Airport for Dubbo, New South Wales. Two flight crew and six passengers were on board the regular public transport flight.

Just after the aircraft reached the cruising altitude of FL 160, the captain who was the pilot monitoring, noticed the right engine exhaust gas temperature (EGT) gauge was indicating just outside the top of the green arc. The captain reduced the power to the right engine, but there was no corresponding reduction in the EGT.

The flight crew conducted the quick reference handbook (QRH) emergency checklist for the lack of response to power lever movement, the power lever was checked after about 5 minutes and was found to still be unresponsive.

The crew advised the controller of their situation and requested a new clearance to return to Newcastle. The crew also advised the controller that as a precaution they might conduct an in-flight engine shut down. The controller gave them a clearance to descend and track direct to Newcastle. The controller initiated an alert phase and the airport emergency services were requested to be on standby.

The flight crew conducted the QRH engine in-flight shutdown checklist and shutdown the right engine prior to commencing their descent to Newcastle.

On descent, passing through about 8,000 ft the captain became the flying pilot and the first officer the monitoring pilot. The crew conducted a visual approach and landed without further incident. The two crew and six passengers were not injured and the aircraft was not damaged.

It is important when time permits to broadcast a ‘pan’ or ‘mayday’, whichever is applicable, to air traffic control to alert the controller and remove any uncertainty about the severity of the situation.
