Qantas grounds six planes to check maintenance files

Australia's airline safety body said Wednesday it would expand its investigation of Qantas after the company announced it temporarily pulled six aircraft from service because of irregularities in maintenance records. Three flights were canceled Tuesday night after Qantas pulled the planes. It was the latest in a spate of incidents with the airline since one of its planes made an emergency landing in Manila last month after an explosion tore a large hole in the fuselage. Qantas said the six B737-400s would be removed from service while the airline cross-checks maintenance records relating to work carried out at one of its Australian facilities.
