Final Report


At about 0936 Central Daylight-saving Time on the 10 November 2016, a QantasLink Bombardier DHC 8 315 aircraft, registered VH-SBB, was on approach to Adelaide Airport South Australia. Two flight crew, two cabin crew and 43 passengers were on board the regular public transport flight.

At this time, the flight crew contacted air traffic control and informed the approach controller that they were at 9,000 ft. Soon after, the first officer, noticed that the captain’s electronic attitude director indicator (EADI) screen had gone blank. The flight crew conducted the display failure checklist.

The flight crew were then cleared to descend they noticed a faint electrical smell, they were not able to identify the source of the smell but suspected that it originated from the failed EADI screen.

The flight crew determined that the smell was getting worse and conducted their phase one-memory checklist items for a fuselage fire or smoke.

At about 0943, the flight crew made a PAN PAN call to air traffic control and advised that they had an instrument failure and electrical smell. The flight crew advised the tower controller that they would require emergency services on standby.

The aircraft landed, taxied onto taxiway E and stopped just passed the holding point clear of runway 12. All passengers and crewmembers disembarked the aircraft.

There were no injuries as a result of the occurrence and the aircraft was not damaged.

Many factors come into play when pilots make decisions in the aviation environment. There are many different models and tools that pilots can use for effective decision making, such as GRADE, as was used by the captain in this event. The models involve a systematic approach to decision making, to consistently determine the best course of action in response to a given situation.
