The Australian Transport Safety Bureau is investigating an incident where an Emirates Airline Airbus A380 descended below minimum assigned altitude while on approach to land at Melbourne Tullamarine International airport.
The Bureau’s safety investigations and reports website says that the aircraft, registered A6-EDM (MSN 42), was operating a flight from Auckland on 14 July when the incident occurred. It was positioned around 28km south of the airport at the time.
“When cleared for the runway 34 RNP approach, the aircraft descended below its assigned altitude of A030 and out of controlled airspace. The controller alerted the crew and the aircraft climbed back to A030,” it says.
The operational incident is being investigated, with an expected completion of July 2017.
According to Flightglobal the Engine Alliance GP7270-powered A380 was built in 2010, and is owned by the airline.
