Virgin Blue wheel problem blamed on axle corrosion

A CORRODED axle is being blamed for a nosewheel coming off a Virgin Blue plane as it taxied at Melbourne Airport on Saturday.
The aircraft was at the end of the runway when a ground engineer noticed one of the wheels had fallen off. The crew were apparently unaware of the problem.
Virgin Blue chief executive Brett Godfrey today rejected claims from aircraft engineers that the fault would have been picked up in an overnight pre-flight safety check.
“In a nutshell, that type of issue with the nosewheel would not have been found on a general inspection,†he said. “You have to take the wheel off, you have to get access to the axle.
“It was an actual axle shear and the early indications were that it was corrosion. If that turns out to be case, you typically find corrosion of that magnitude when major checks, basically when the aircraft is stripped down.â€
Mr Godfrey said the aircraft would have still functioned with one wheel and he believed the airline’s safety management system exceeded required standards.
He said the aircraft had been overhauled by Lufthansa Technik about 12 months ago and this sort of problem was rare.
The airline had inspected all aircraft around the same age and with a similar number of landing and take-off cycles and there were no signs of cracks, corrosion or fatigue.
“At this early stage, we think it was an anomaly,†he said.
Australian Licensed Aircraft Engineers Association federal secretary Steve Purvinas had earlier said the nosewheel fault could have caused serious problems.
Mr Purvinas said Virgin Blue checked its planes every day, but not always before each flight.
"We say that there would have been some tell-tale signs here that this wheel was ready to give way and unfortunately it wasn't picked up," he said.
The Australian Transport Safety Bureau is investigating.
