Qantas has stood down two pilots after they failed to lower the landing gear on a flight into Sydney last week.

Qantas says the flight crew received a cockpit alert after what the airline has described as a “brief communications breakdown”.

It says the flight crew on the Melbourne to Sydney service responded quickly to the problem and started “a go around” before landing safely.

The incident has been reported to the Australian Transport Safety Bureau while Qantas is carrying out its own investigations.

A spokesman for the Australian and International Pilots Association, Captain Barry Jackson, says the investigation will look at what action the pilots took.
