According to new findings released today, a flawed oil feed pipe could have been a cause of the oil fire that led to an uncontained engine failure in the Rolls-Royce Trent 900 engine on Qantas’ QF32 on Nov. 4.
The Australian Transport Safety Bureau released this recommendation a day before a more comprehensive report on the incident is due. Pictured below is a stub pipe taken from the QF32 engine, showing where fatigue cracking occurred. This was in a part of the pipe where the wall was thinner, due to a misaligned counter-bore.
The pipe is one of the components being examined at the Rolls-Royce facility in Derby, U.K. Qantas believes this latest finding “appears to provide a more definitive explanation for [Nov. 4] the engine failure.”
