A New Zealand-bound Qantas flight had to be aborted minutes before takeoff when wing damage was discovered by an engineer at Sydney airport.

The Christchurch-bound Qantas 747-300 was taxiing towards the runway at 9.15am (AEST) Saturday, when an engineer noticed damage to its right wing flap.

The engineer notified the pilot, who aborted the flight.

Qantas said all 213 passengers on the plane had been provided with accommodation and meal vouchers, and booked on another flight on Sunday morning.

The cause of the damage was being assessed, a spokeswoman for the airline said.

The aborted flight is the latest mishap in recent months to plague the flying kangaroo.

In July a Qantas 747 had its belly torn open when an oxygen tank exploded on a flight over Manila, sparking an Australian Transport Safety Bureau investigation.

And in October a Qantas plane suffered a dramatic midair plunge on a flight from Singapore to Perth, where the plane fell 200m in 20 seconds, hurling unrestrained passengers around the cabin.

About 40 passengers were taken to hospital after the plane made an emergency landing in Learmonth, near Exmouth in Western Australia’s north.
