The Boeing 737 flight from Sydney was towed from the runway after a hydraulics failure during a landing Sunday night landing, The (Melbourne) Courier-Mail reported Tuesday.

The newspaper reported an engineering source said a "large pipe -- a kind of artery" failed on the plane's primary hydraulics system.

A retired engineer blamed the accidents on too many "pencil inspections" being done on Qantas planes.

"It involves someone ticking off a document to say something has been done when it has not," he said.

On Friday, a Qantas jumbo jet made an emergency landing in Manila with a hole in its fuselage. Then, on Monday night, a Melbourne-bound Qantas plane had to return to Adelaide because the doors covering the nose wheel bay would not close properly after take-off.
