( CNN ) -- An A380 superjumbo bound for Sydney came loose from a tow truck and partially rolled onto grass at Singapore airport . Singapore Airlines was the first carrier in the world to operate the double-decker aircraft . No-one was injured in the incident involving the world 's biggest airliner , a Singapore Airlines spokesman said , but passengers were taken off so the plane could be repositioned and inspected for any damage . A truck being used to push back the plane in preparation for the flight `` experienced some form of failure '' causing it disconnect from the aircraft , a Singapore Airlines spokesman said . `` As a consequence of the failure on the truck , the aircraft ... came into contact with the grass verge off the airport tarmac . The aircraft was not under its own power at the time , '' he said . `` It is too early at this time to know the cause of the incident but Singapore Airlines will investigate this quickly , and is filing reports with the appropriate Singapore authorities , '' the spokesman said . An airline spokesman told CNN 's Richard Quest that four wheels had ended up on the grass . All four tires had now been replaced . `` As far as Singapore Airlilnes is concerned , the plane is ready to fly again , '' Quest said . The airline made arrangements for as many customers as possible to continue on their journey from Changi Airport to Sydney aboard a Boeing 747-400 . Most passengers departed for Sydney on a new flight early Friday morning , while some others flew to alternate destinations such as Melbourne and Brisbane on existing flights . `` The remaining customers , about 10 of them , have left , or will be leaving , for Sydney today , '' the spokesman said . Singapore Airlines received its first A380 in October last year to become the first carrier in the world to operate the double-decker aircraft , which it is currently using for the Singapore-Sydney route . Changi Airport , which is home to the Singapore Airlines A380 fleet , has declared itself ready to handle the plane . It widened and lengthened existing runways and widened runway shoulders to allow the plane to maneuver . Airports around the world have had to make changes to accommodate the A380 , such as enlarging runways and gates and bringing in vehicles which can tow the plane and lift high enough to reach its upper decks .
