However,staff were shocked to discover that a larger amount of freight than expected had been loaded into the rear hold of the plane,resulting in it breaching its maximum take-off weight by about 160 kilograms when it departed Sydney Airport.
Qantas confirmed that it was investigating how freight was “incorrectly loaded” onto the Dash-8,which has since been cleared to re-enter service.
“The flight operated normally and landed safely and without incident,” it said,adding that the safety of the flight was not compromised.
Mick Quinn,a former head of safety at Emirates and an ex-manager of air-safety investigation at Qantas,said overloading or incorrect loading of cargo in the wrong positions affects an aircraft’s centre of gravity and raised the risk of flight control difficulties.
“While aircraft are designed to have safety margins that will tolerate minor deviations in weight and balance,any deviation may produce a structural or aerodynamic risk,” he said.
Quinn,a former deputy CEO of the Civil Aviation Safety Authority (CASA),said runway length,temperature and wind direction were also among conditions that contribute to critical calculations of speed and safe flights.
