On Monday, a Qantas flight which was bound for Buenos Aires came back to Sydney due to some technical problems. After its Airbus A390 superjumbos landed due to an engine failure, for the Qantas Airlines, this is second such safety failure incident.

As the investigation is still on about the partial disintegration of a Rolls-Royce engine on November 4, the Qantas had grounded the fleet of six Airbus A380s. P

resently the airline is depending upon its fleet of 26 Boeing 747s for the long haul routes which are busy. Since its launch in 2007, the world's largest passenger plane has beset with the serious incidents, the latest of which was the engine failure of November 4, which was caused by an oil fire.

These incidents have hit the Airbus who had manufactured the plane. These failures have hit the stock of aviation, which in turn have prompted the Airbus to warn the investors about the setbacks in delivery of the plane. In Singapore, a Qantas Boeing 747 made an emergency landing due to the engine failure just after two days following A380 incident.
